Water System Design for Layer Houses: Pipes, Pressure, and Flow

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Peak water demand for laying hens can be 2-3 times the average hourly rate, and can double or triple during heat stress, necessitating system design for these extreme conditions to prevent reduced feed intake and egg production.
• Nipple drinker flow rates should be set between 60-100 mL/minute for mature layers, with operating pressure at the drinker line typically maintained between 2-6 psi, adjusted based on bird observation and manufacturer specifications.
• Friction loss in water pipes is critical; main supply lines should be at least 1 inch for runs over 100 feet, and drinker lines should also be 1 inch for lengths over 100 feet to ensure adequate pressure at the farthest nipple.
• Water quality parameters such as pH (6.0-8.0), Total Dissolved Solids (<1,000 ppm), and absence of significant iron (>0.3 ppm) or bacterial contamination are crucial for bird health and drinker function.
• Daily monitoring of water consumption, pressure, and bird condition, alongside weekly checks of chlorine residual (2-5 ppm) and nipple flow rates, serves as an early warning system for potential health or system issues.
• Common design errors include undersizing main lines, ignoring friction loss, setting pressure too high, inadequate filtration, and failing to plan for heat stress, all of which can compromise flock performance.

Water is the most essential nutrient for laying hens, yet it is often the most overlooked component of a poultry operation. A mature layer will drink between 0.25 and 0.5 liters of water per day under normal conditions, and that volume can double or triple during heat stress. If your water system cannot deliver adequate flow at the right pressure to every nipple in the house, you will see reduced feed intake, lower egg production, poor shell quality, and increased mortality before you ever notice a problem with the birds themselves.

This guide is for poultry farmers, farm managers, and technical staff who are planning a new layer house, renovating an existing water system, or troubleshooting performance issues. It covers the fundamentals of water system design for layer houses, including pipe sizing, pressure management, nipple drinker flow rates, water quality considerations, and the recordkeeping practices that keep a system performing year after year. The goal is to give you a practical framework for making design decisions that support bird health and production efficiency.

At a Glance

Before diving into the technical details, here is a quick summary of the most important points covered in this guide:

These numbers are starting points. Your specific flock size, house layout, and local water quality will influence the final design. The sections below explain how to make those calculations and adjustments properly.

Understanding Water Requirements for Laying Hens

Water intake drives feed intake. When hens reduce water consumption for even a few hours, feed intake drops proportionally, and the effects on egg production can last for days. Understanding what drives water consumption is the first step in designing a system that meets your flock's needs.

Factors That Influence Water Intake

The primary factors affecting how much water your layers will drink include:

Environmental temperature. Hens drink more as temperatures rise. At 70°F (21°C), a layer may consume around 0.25 liters per day. At 90°F (32°C), that can rise to 0.5 liters or more. In extreme heat, consumption can approach 1 liter per bird per day. Your system must be sized for these peak conditions, not for average days.

Feed composition. Diets high in protein, salt, or certain minerals increase water requirements. If you feed a high-calcium layer ration, expect higher water intake as the birds regulate mineral balance. Changes in feed formulation should prompt a review of water system capacity.

Egg production level. Hens producing at high rates need more water to support egg formation, particularly for shell development. A hen laying at 90 percent production consumes more water than one laying at 70 percent.

Bird age and body weight. Larger breeds and older hens drink more than smaller or younger birds. If you house multiple ages or breeds, account for the heaviest group in your design calculations.

Health status. Sick birds may drink more or less depending on the condition. Respiratory disease, diarrhea, and certain metabolic disorders increase water needs. A sudden change in water consumption is often the first sign of disease, which is why daily monitoring matters.

Calculating Total Water Demand

To size your system, calculate the peak water demand for the house. Use the highest realistic consumption figure, not the average.

For example, consider a house with 20,000 laying hens. Under normal conditions at 75°F, expect 0.3 liters per bird per day. That is 6,000 liters or about 1,585 gallons per day. Divide by 24 hours to get an average hourly flow of about 66 gallons per hour, or roughly 1.1 gallons per minute.

But birds do not drink evenly throughout the day. They drink heavily around feeding times and during the early morning and late afternoon. Peak demand can reach 2 to 3 times the average hourly rate. For design purposes, multiply the average hourly rate by 2.5. In this example, peak demand would be about 2.75 gallons per minute.

Now factor in heat stress. During a heat wave, consumption might double. That puts peak demand near 5.5 gallons per minute for a 20,000 bird house. Your system should be capable of delivering at least this volume at the pressure required by your drinker lines.

Water Consumption as a Management Tool

Because water intake changes before other visible signs of trouble, daily water consumption records serve as an early warning system. A drop of 10 percent or more from the previous day warrants investigation. Check drinker function, water pressure, water quality, and bird behavior. If consumption remains low for more than 24 hours, consult your veterinarian or extension agent.

Poultry Water Pressure and Nipple Drinker Flow Rates

Nipple drinkers are the standard for commercial layer operations because they keep water clean and reduce spillage. However, nipple drinkers only perform well when pressure and flow are correctly set for the age and size of the birds.

How Nipple Drinkers Work

A nipple drinker consists of a stainless steel pin inside a plastic or brass body. When the bird pecks or pushes the pin upward, water flows around the pin and into the bird's mouth. The amount of water delivered depends on the drinker design, the water pressure at the nipple, and the length of time the bird activates the pin.

Two basic types of nipple drinkers are used in layer houses:

Threaded nipples screw directly into the pipe. They are simple and reliable but can be difficult to replace if they fail. They are often used in houses where the drinker line is replaced periodically.

Push-in nipples fit into a grommet or socket in the pipe. They are easier to install and replace but require a properly sized hole and a secure seal to prevent leaks.

Both types are available with different flow rates and trigger forces. For mature layers, choose a nipple with a flow rate between 60 and 100 mL per minute at the operating pressure you plan to use. High-flow nipples are useful in hot climates where birds need more water, but they also increase spillage and manure moisture if pressure is set too high.

Setting Operating Pressure

The pressure at the drinker line is controlled by a pressure regulator, usually located at the start of each line. Most layer houses operate between 2 and 6 psi at the regulator. The correct pressure depends on the nipple type and the age of the birds.

Start with a lower pressure, around 2 to 3 psi, and observe the birds. If they are spending too much time at the drinkers or appear to be struggling to get enough water, increase pressure in small increments. If you see water pooling under the drinkers or excessively wet droppings, reduce pressure.

A simple way to check flow rate is to hold a graduated cylinder under a nipple and activate it for 30 seconds. Multiply the volume by 2 to get the flow per minute. Compare this to the manufacturer's specification for the nipple at your operating pressure. If flow is significantly lower than expected, the problem may be low line pressure, a clogged filter, or worn nipples.

Pressure Loss Along the Line

Pressure at the regulator is not the same as pressure at the last nipple in the line. Friction between water and the pipe walls reduces pressure as water travels through the line. The amount of pressure loss depends on pipe diameter, flow rate, pipe length, and the number of fittings and elbows.

For a drinker line with a regulator at one end and a flush valve at the other, pressure at the far end may be 1 to 2 psi lower than at the regulator. This is normal and must be accounted for when setting the regulator.

If you have long lines, consider installing a mid-line pressure regulator or using a larger diameter pipe to reduce friction loss. Some growers use a regulator at both ends of the line to maintain more uniform pressure. Alternatively, you can install a pressure gauge at the far end of the line to verify actual pressure and adjust accordingly.

Common Nipple Problems and Fixes

Leaking nipples waste water and keep litter wet. Leaks are often caused by debris holding the pin open, worn seals, or excessive pressure. Check for drips regularly and replace faulty nipples promptly.

Clogged nipples reduce water availability. Sediment, mineral scale, and biofilm can block the pin mechanism. A good filtration system and regular line flushing prevent most clogs.

Trigger force too high makes it hard for birds to get water. This can happen with new nipples that have stiff springs or with certain nipple designs. If you see birds pecking at nipples repeatedly without drinking, check trigger force and consider a different nipple type.

Incorrect nipple height forces birds to stretch or crouch. The nipple should be at or slightly above the bird's head level so the bird drinks in a natural position. Adjust line height as the flock matures.

Water Pipe Sizing for Layer Houses

Pipe sizing is the most common design error in layer house water systems. Undersized pipes cause pressure drops, reduced flow, and uneven water delivery across the house. Oversized pipes waste money and can create problems with water stagnation and cleaning.

Basic Principles of Pipe Sizing

Water flows through a pipe at a rate determined by the pipe diameter and the pressure pushing it. Larger pipes carry more water with less friction loss, but they cost more and hold more water that can stagnate between flocks.

The goal of pipe sizing is to deliver the peak water demand to every drinker line at the pressure required by the nipples. This requires knowing the flow rate and the acceptable pressure loss over the length of the pipe.

Friction Loss Calculations

Friction loss is expressed in pounds per square inch (psi) per 100 feet of pipe. It depends on the pipe material, diameter, flow rate, and the condition of the pipe interior. Smooth pipes like PVC and polyethylene have lower friction than rougher materials like galvanized steel.

A simplified approach for most layer houses is to use a friction loss chart for the pipe material you plan to install. These charts are available from pipe manufacturers and from extension publications. Find your flow rate on the chart and read the friction loss per 100 feet for the pipe diameter you are considering.

As a rule of thumb, keep friction loss below 2 psi per 100 feet of pipe for the main supply line. For drinker lines, keep friction loss below 1 psi across the full length of the line. This ensures the last nipple in the line still receives adequate pressure.

Practical Pipe Sizing Recommendations

For most commercial layer houses, the following guidelines apply:

Main supply line from the water source to the house: Use 1 inch minimum for houses up to 500 feet from the source. For longer runs or houses with more than 20,000 birds, use 1.5 inch or larger. The main line must deliver the total peak demand for the house without excessive pressure loss.

Distribution lines within the house: These are the lines running the length of the house, typically along the feed lines or between rows of cages. For houses up to 400 feet long, 1 inch PVC or polyethylene is adequate for most layer operations. For longer houses or high-demand situations, use 1.25 inch or 1.5 inch.

Drinker lines: These are the lines with nipples attached. They are usually 0.75 inch or 1 inch in diameter. For lines over 100 feet, use 1 inch to reduce pressure loss along the line. Some manufacturers offer larger diameter drinker lines for high-flow applications.

Riser pipes and vertical drops: Use the same diameter as the line they feed. Avoid reducing diameter at the point of connection, as this creates a pressure drop.

Fittings and Valves

Every fitting, elbow, tee, and valve adds friction and reduces pressure. Minimize the number of fittings in the system and use long-radius elbows where possible. Ball valves have lower friction than gate valves and are easier to operate.

Install a main shutoff valve at the water entry point to the house and individual shutoff valves for each drinker line. This allows you to isolate sections for maintenance or to control water during flock depopulation.

Water Hammer and Surge Protection

When valves close quickly, the sudden stop of water creates a pressure spike known as water hammer. This can damage pipes, fittings, and drinkers. Install air chambers or water hammer arrestors at the end of long lines and near quick-closing valves. Slow-closing valves reduce the risk of water hammer.

Water Quality for Layers

Water quality affects bird health, drinker performance, and the effectiveness of medications and vaccines administered through the water. Poor water quality can reduce consumption even when the system delivers adequate volume and pressure.

Key Water Quality Parameters

pH. Water with a pH between 6.0 and 8.0 is generally acceptable for layers. Extremely acidic water can corrode metal fittings and reduce the effectiveness of some vaccines. Alkaline water can promote mineral scale buildup in pipes and drinkers.

Total dissolved solids (TDS). TDS measures the total concentration of dissolved minerals in water. Levels below 1,000 ppm are considered safe for poultry. Higher levels can cause reduced water intake, diarrhea, and poor performance. If TDS exceeds 3,000 ppm, find an alternative water source.

Hardness. Hard water contains high levels of calcium and magnesium. While these minerals are not directly harmful to birds, they cause scale buildup in pipes and drinkers. Scale reduces flow and can clog nipples. Water softeners or periodic acid flushing can manage hardness problems.

Iron and manganese. These metals cause staining and can support the growth of iron bacteria that clog pipes. Levels above 0.3 ppm iron or 0.05 ppm manganese can cause problems. Filtration or aeration can remove these metals.

Nitrates and nitrites. High nitrate levels, above 10 ppm, can affect bird health and indicate contamination from fertilizer or animal waste. Test water from new wells and from wells near agricultural activity.

Bacterial contamination. Total coliform bacteria should be absent from drinking water. E. coli indicates fecal contamination and requires immediate action. Shock chlorination of the well and water system is the first response, followed by retesting.

Chlorine residual. If you chlorinate the water, maintain a residual of 2 to 5 ppm at the farthest drinker. This controls bacterial growth in the lines without affecting bird intake. Test chlorine levels weekly and after any system changes.

Water Testing

Test your water source before building a new house and at least annually thereafter. More frequent testing is warranted if you notice changes in bird performance, drinker clogging, or water appearance. A standard poultry water test includes pH, TDS, hardness, iron, manganese, nitrates, and bacterial counts.

Your local extension office can recommend a testing laboratory and help interpret results. If you use a private lab, ask for the poultry drinking water standards so the report is formatted for your needs.

Water Treatment Options

Depending on your water quality test results, you may need one or more treatment steps:

Filtration removes sediment and suspended solids that clog drinkers. A 50 micron filter is adequate for most systems. Finer filters, down to 5 microns, remove more particles but clog faster and require more frequent replacement. Install filters at the water entry point and check them weekly.

Water softening removes calcium and magnesium to prevent scale. Softening is useful in areas with hard water but adds sodium to the water. Monitor sodium levels to ensure they stay within acceptable ranges.

Chlorination controls bacterial growth in the water system. Use a metering pump to inject chlorine solution at a rate that maintains the desired residual. Do not add chlorine to water that will be used for live vaccines, as it will inactivate the vaccine.

Acidification lowers water pH to control bacteria and reduce scale. Organic acids are commonly used. Acidified water can corrode metal components, so use plastic or stainless steel fittings.

Reverse osmosis removes most dissolved minerals and contaminants. It is expensive and produces a large volume of waste water, so it is rarely used for commercial poultry operations unless the source water is severely contaminated.

Designing the Water System Layout

A well-designed water system delivers water to every bird with minimal pressure variation and minimal maintenance. The layout should follow the house design and support the management practices you use.

Main Line Placement

The main water line typically enters the house at one end or in the middle, depending on the location of the water source and the house orientation. From the entry point, the line runs the length of the house, with takeoffs to each drinker line.

For houses with a central feed alley, the main line is often installed along the alley or above the cages. For floor houses, the main line runs along a wall or down the center aisle.

Drinker Line Configuration

Drinker lines run parallel to the feed lines, with nipples spaced according to the manufacturer's recommendation. For layers in cages, typical nipple spacing is 8 to 10 inches, with one nipple available for every 4 to 6 birds. For floor operations, provide one nipple per 8 to 10 birds.

Each drinker line should have its own pressure regulator and a flush valve at the far end. The regulator maintains the correct pressure for the nipples, and the flush valve allows you to clean the line and remove sediment.

Elevation and Slope

Water lines should be installed with a slight slope, about 1 to 2 percent, toward the flush valve. This allows the line to drain completely when needed and helps move sediment to the flush point. The slope is especially important in houses where lines are flushed regularly.

Access for Maintenance

Design the system with maintenance in mind. Install access points at regular intervals so you can inspect and clean lines. Union fittings allow you to disconnect sections for repair. Label all valves and lines so workers can identify them quickly.

Expansion and Future Needs

If you plan to expand the house or increase bird numbers, design the water system with extra capacity. Oversizing the main line by one pipe size costs little and provides flexibility for the future. Installing extra takeoff points and valves makes it easier to add drinker lines later.

Step-by-Step Water System Design Process

Follow these steps to design a water system for a new layer house or to evaluate an existing system.

Step 1: Determine Peak Water Demand

Calculate the number of birds in the house and estimate peak daily water consumption. Use the highest expected consumption rate, which occurs during heat stress. Multiply the number of birds by the per-bird consumption to get total daily demand.

For example, 20,000 birds at 0.5 liters per bird per day equals 10,000 liters per day. Convert to gallons by multiplying by 0.264, which gives 2,640 gallons per day. Divide by 24 hours to get an average hourly flow of 110 gallons per hour, or about 1.8 gallons per minute.

Apply a peaking factor of 2.5 to account for uneven drinking patterns. This gives a design flow of 4.5 gallons per minute. During heat stress, double this to 9 gallons per minute. This is the flow your system must deliver at peak conditions.

Step 2: Determine Required Pressure

Check the nipple drinker manufacturer's specifications for the recommended pressure range and flow rate. Most layer nipples operate at 2 to 6 psi. Choose a target pressure in the middle of the range, around 3 to 4 psi, and verify that the nipples deliver the desired flow at that pressure.

Step 3: Calculate Friction Loss

Using a friction loss chart for your pipe material, calculate the pressure loss for each section of the system. Start at the farthest drinker line and work back to the water source. Add the friction loss for each section to determine the total pressure required at the source.

For example, if the farthest drinker line is 300 feet from the main line connection and the main line is 200 feet long, calculate the friction loss for both sections at the design flow rate. If the drinker line loses 0.5 psi and the main line loses 1 psi, the total friction loss is 1.5 psi. Add this to the required pressure at the last nipple, about 3 psi, to get a minimum pressure of 4.5 psi at the main line connection.

Step 4: Select Pipe Sizes

Choose pipe diameters that keep friction loss within acceptable limits. Use the friction loss chart to compare options. Select the smallest diameter that meets your pressure requirements to minimize cost, but consider future expansion needs.

Step 5: Design the Regulator and Valve Layout

Plan the location of pressure regulators, shutoff valves, and flush valves. Each drinker line needs a regulator at the start and a flush valve at the end. The main line needs a shutoff valve at the house entry and additional valves for each branch.

Step 6: Plan Water Treatment

Based on your water quality test, plan the treatment equipment needed. Include filtration, chlorination, or other treatment as required. Install treatment equipment before the main line so all water entering the house is treated.

Step 7: Verify With a Pressure Test

After installation, test the system before placing birds. Fill the lines, check for leaks, and verify pressure at multiple points. Measure flow at the farthest nipples to confirm the system meets design specifications.

Monitoring and Recordkeeping

A water system performs best when you monitor it regularly and keep accurate records. Consistent monitoring helps you detect problems early and track the effectiveness of your management practices.

Daily Checks

Walk the house at least once daily and check:

• Water consumption from the flow meter or by reading the water level in the header tank
• Water pressure at the regulators
• Signs of leaking nipples or wet spots under the lines
• Bird behavior at the drinkers, including any signs of difficulty drinking
• Water appearance, including clarity and any unusual color or odor

Record your observations in a logbook or digital record. Compare daily consumption to the previous day and to the expected range for your flock size and house temperature.

Weekly Checks

Once per week, perform more detailed checks:

• Test chlorine residual at the farthest drinker
• Measure nipple flow rate at several locations along each line
• Check filters and clean or replace as needed
• Inspect regulators for proper operation and adjust if pressure has drifted
• Check for mineral scale or biofilm buildup in the lines

Monthly and Seasonal Checks

Monthly, review your water consumption records and look for trends. Compare consumption across flocks and seasons. Check water quality with a simple test kit for pH and hardness.

Before hot weather arrives, inspect the entire system to ensure it can handle increased demand. Flush all lines, replace worn nipples, and verify that cooling systems are working.

Record Keeping

Keep the following records for each house:

• Daily water consumption
• Water pressure readings
• Water quality test results
• Nipple flow rate measurements
• Treatment chemical usage
• Maintenance and repair activities
• Any bird health issues related to water

These records help you identify patterns and make informed decisions. They also provide valuable information when consulting with your veterinarian or extension agent.

Using Water Consumption Data

Compare daily water consumption to feed consumption. A normal ratio is about 2 parts water to 1 part feed by weight. If the ratio changes significantly, investigate the cause.

A sudden drop in water consumption often precedes a drop in feed intake and egg production. Check the system first, then look at bird health. If consumption does not recover within 24 hours, contact your veterinarian.

Common Mistakes in Water System Design

Learning from the mistakes of others can save you time and money. Here are the most common water system design errors seen in layer houses.

Undersizing the Main Line

The most frequent mistake is installing a main line that is too small. This causes pressure drops when multiple drinker lines draw water simultaneously. The result is reduced flow at the farthest nipples, especially during peak drinking times. Always calculate peak demand and size the main line to handle it with margin.

Ignoring Friction Loss

Many growers set the pressure regulator to the desired pressure at that point but do not account for pressure loss along the drinker line. The last nipples in the line may receive significantly less pressure than the first. Install pressure gauges at the far end of long lines to verify actual conditions.

Setting Pressure Too High

High pressure causes nipples to leak, spillage to increase, and litter to become wet. Wet litter leads to foot problems, ammonia production, and fly infestations. Start with low pressure and increase only as needed.

Poor Water Quality Management

Failing to test water or ignoring test results leads to chronic problems with clogged drinkers, mineral scale, and bacterial growth. These problems are difficult to correct once established. Test water before building and regularly thereafter.

Inadequate Filtration

Sediment and debris in the water clog nipples and wear out regulators. A simple filter can prevent most of these problems. Install a filter with the correct micron rating for your water source and check it regularly.

Not Planning for Heat Stress

Systems designed only for average conditions fail during heat waves. Water demand can double or triple in hot weather. If your system cannot deliver that volume, you will see reduced feed intake and egg production during the hottest part of the year.

Neglecting Maintenance

Even a well-designed system fails without regular maintenance. Nipples wear out, regulators drift, filters clog, and scale builds up. Establish a maintenance schedule and stick to it.

Using Incompatible Materials

Mixing incompatible materials, such as galvanized steel and copper, can cause corrosion. Use materials recommended by the system manufacturer and avoid mixing metals in the same line.

When to Call a Veterinarian or Extension Agent

Most water system issues are mechanical and can be resolved by the farm team. However, some situations require professional assistance.

Contact Your Veterinarian When

• Water consumption drops by more than 10 percent and does not recover within 24 hours
• Birds show signs of dehydration, including lethargy, reduced feed intake, or increased mortality
• You suspect waterborne disease or contamination
• Birds are not drinking even when water is available and pressure is correct
• You see neurologic signs or other symptoms that could indicate a water-related toxicosis

Your veterinarian can help rule out disease and recommend appropriate testing or treatment.

Contact Your Extension Agent When

• You are designing a new house or major renovation and need help with calculations
• Water quality tests show levels outside recommended ranges
• You are considering new water treatment equipment and need guidance
• You want help interpreting water consumption records or troubleshooting performance issues
• You need recommendations for laboratories, equipment suppliers, or system manufacturers

Extension agents have access to research-based information and can connect you with specialists in poultry water systems.

Frequently Asked Questions

How much water do laying hens need per day?

A mature laying hen typically drinks 0.25 to 0.5 liters per day under normal conditions. During heat stress, consumption can rise to 1 liter per bird per day. The exact amount depends on temperature, feed composition, egg production level, and bird size. Monitor actual consumption in your house and compare to these ranges to detect problems early.

What is the correct water pressure for nipple drinkers in a layer house?

Most nipple drinkers for mature layers operate at 2 to 6 psi at the drinker line. Start at 2 to 3 psi and observe the birds. If they are struggling to get water, increase pressure gradually. If you see leaking nipples or wet litter, reduce pressure. Always check the manufacturer's recommendation for your specific nipple model.

How do I measure nipple drinker flow rate?

Hold a graduated cylinder under a nipple and activate it for 30 seconds. Multiply the volume collected by 2 to get the flow rate in milliliters per minute. Compare this to the manufacturer's specification for your nipple at the operating pressure. Measure flow at multiple nipples along the line to check for pressure loss.

What size pipe should I use for the main water line in a layer house?

For most commercial layer houses, use 1 inch minimum for the main supply line. For houses over 500 feet from the water source or with more than 20,000 birds, use 1.5 inch or larger. Calculate friction loss at your peak flow rate to confirm the pipe size is adequate.

How often should I flush the drinker lines?

Flush drinker lines at least weekly to remove sediment and biofilm. Flush more frequently if you have hard water, high iron levels, or problems with clogged nipples. Flushing is especially important before placing new birds and after any treatment or medication through the water system.

What water quality tests should I run for my layer house?

At minimum, test pH, total dissolved solids, hardness, iron, manganese, nitrates, and bacterial counts. Test your water source before building and annually thereafter. Test more frequently if you notice changes in bird performance or drinker function. Your extension office can recommend a testing laboratory.

How do I know if my water pressure is too high?

Signs of excessive pressure include leaking nipples, wet litter, increased water consumption without a corresponding increase in feed intake, and wet droppings. Measure the actual flow rate at the nipples and compare to the manufacturer's specification. If flow exceeds the recommended range, reduce pressure at the regulator.

Can I use well water for my layer house?

Yes, many layer houses use well water. However, well water must be tested for bacterial contamination, minerals, and other parameters before use. Wells near agricultural activity or septic systems are at higher risk for contamination. Test regularly and treat as needed.
