Water Conservation

It is important to preserve the City of Concord's water source, Penacook Lake. Water conservation measures can be taken to help limit water consumption. The City of Concord saves water with help from the City's Water Conservation Technician by conducting leak detection surveys, performing water audits, and partnering with the EPA's WaterSense Program.

Did you know that less than 1% of all the water on Earth is available for human consumption? The average American uses over 80 gallons of water a day and clean drinking water is becoming a vanishing resource. Conserving water can help maintain our water sources. Penacook Lake is Concord's water source; help conserve it for future generations by limiting your water use.

Here are some ways to conserve our water supply and save money on your water bill:


Outdoor Conservation

Car Washing

Wash your car in sections and rinse with short spurts from the hose. If you need to wash often, go to a car wash that recycles water. Try to wash cars near plant life to allow overflow to benefit the greenery.


Select native species that don’t need as much water. Mulch heavily. Let grass grow higher in dry weather – saves burning and saves water.


Practice smart watering. Water slowly and as infrequently as possible. Water at night or early morning to minimize evaporation, preferably between the hours of 7:00 p.m. to 8:00 a.m. Inspect lawn irrigation systems annually to prevent misaligned heads from wasting water. Keep a close watch on wind shifts while using sprinklers. Consider a weather based controller instead of a clock based timer. Try using a rain barrel as a source of irrigation water.


Cover when not in use to prevent evaporation. Avoid over-filling to prevent spilling.


Bathroom Waste


Do not flush to dispose of trash. Save water by flushing when necessary. Consider upgrading your toilet to a WaterSense labeled model, which requires less water when flushing. Displace water in the tank to save water by using plastic bottles or bags filled with water and weighted with pebbles. Check for leaks by listening for running water or by adding food coloring to the water tank. A leak is present if the coloring appears in the toilet bowl within the hour without flushing. Watch our instructional video on how to detect a toilet leak.

Shower / Tub

Turn off water while lathering and try to shower for less than five minutes with a light spray. A full tub can hold 50+ gallons of water, so if you use the tub do not overfill and try to use less than half. Check faucet for leaks and replace faulty fixtures.


Clean shaving razors and toothbrushes with an occasional burst of water. Do not keep the faucet running. Check faucet for leaks and replace faulty fixtures.

In The Kitchen

Replacing Bathroom Fixtures

Garbage Disposals

Use Sparingly. Dispose waste in the garbage to minimize water use.

Washing Fruits & Vegetables

Use a vegetable brush for fruits and vegetables. Spray sparingly with short bursts of water.

Defrosting Food

Plan ahead to thaw frozen foods naturally without using water.

Washing Dishes

Pre-clean dishes by wiping them with paper napkins from your meal. Rinse everything all at once. Soak pots and pans overnight if necessary. Use a dishwasher for full loads only. Check faucet for leaks and replace faulty fixtures.

Drinking Water

Store water in the refrigerator or use ice cubes to get your water cold. Avoid running water at the tap to get cold water. Recycle any unused drinking water for other purposes.


Use appliances that use the least amount of water and energy. Check connections for leaks.

Around the House

Household Leaks

Household Cleaning

Use recycled water for cleaning. Use new water only when necessary.


Reduce waste by insulating hot water pipes to avoiding waiting for hot water at the tap. Inspect water pipes regularly for leaks in connections or pinholes. A pinhole leak can waste up to 170 gallons of water a day.

Washing Machine

Newer machines typically allow you to select load cycles and water levels. Select minimal water use, or only wash full loads. Use cold water to save energy and money.
