Water Sources on Farmland

What are the main sources of farm water?

Common sources include drilled or dug wells, springs, ponds, streams, municipal or rural water systems, and collected rainwater. Many farms use more than one, such as a well for the house and a pond or hydrant for stock.

Each source differs in cost, quality, and risk. A well is dependable but needs power or a pump. A spring costs little but can change flow with the seasons. A pond depends on rain and runoff. A rural water district gives steady supply but costs a monthly fee.

Draw a simple map of your farm showing each water source, the pipes or hoses that leave it, and the places where water is used. This map shows weak points, like a single line serving three barns, and helps you decide where a backup is worth the expense.

What should you know about wells?

Wells draw groundwater and are typically the main supply for rural homes. Private wells are not regulated for quality the way public systems are, so testing is the owner's responsibility. The EPA and your county health department explain what to test for and how often.

Location, depth, construction, and maintenance all affect safety. Keep potential contaminants, such as livestock yards, chemicals, and septic systems, away from the well, and follow local rules on distance. A licensed well driller and your state well program are the right sources for standards.

• Test water with a certified lab and keep records.
• Keep the area around the wellhead clear and sloped away.
• Use licensed contractors for drilling and repair.

What about springs, streams, and ponds?

Springs can provide excellent water, but they need protection from animals and runoff. A properly developed spring box, designed with technical advice, keeps the water cleaner. Surface water from streams and ponds can carry bacteria, algae, and runoff contaminants.

Livestock may drink from ponds, but water quality still matters for animal health, and surface water is generally not safe for people without treatment. Ask the extension office about testing and the NRCS about protecting the source. Streams are often regulated, so check before diverting or fencing.

Test any surface or spring water before you rely on it for drinking, and ask the county health department what the results mean. Never assume clear water is safe, since many harmful contaminants cannot be seen or tasted.

What are the legal rules?

Water rights differ across the country. Some states treat water as owned by the landowner along the stream, and others allocate it by permit or by who used it first. Using or storing water without the proper right can lead to fines or loss of access.

Before depending on any source, contact your state water resources agency to learn what rules apply, and have an attorney look at the deed for any water rights that came with the land or were severed from it.

How can you protect water quality?

Protecting the source is cheaper than cleaning up after it. Keep fuel, fertilizer, pesticides, and manure well away from wells and surface water. Maintain septic systems, and fence livestock out of streams and springs where practical.

Buffer strips of grass or trees along streams filter runoff. The NRCS offers technical help with these practices, and cost-share programs may be available. Ask your local office about current options.

How do you plan for drought?

A dry summer exposes weak water systems. Know how much water your animals and crops need, and how much your source can reliably supply in a bad year. Storage tanks, a second source, and conservation measures give a margin of safety.

Drought.gov and the National Weather Service provide current drought information, and your extension office can share regional guidance. A plan made before a drought is easier than a scramble during one.

What does it cost to keep water reliable?

Water systems are not a one-time cost. Pumps wear out, pipes freeze, filters need replacing, and tanks need cleaning. Ask contractors about expected maintenance and energy use, and set aside a repair fund.

Many rural households and farms share systems with neighbors. If you do, put the agreement about maintenance and costs in writing. A clear understanding prevents arguments when something breaks in the middle of a cold night.

• Budget for pump, pipe, and filter replacement.
• Insulate pipes and protect pumps from freezing.
• Put shared system agreements in writing.
