Community Water Systems

ANNUAL WATER USE REPORTS and SYSTEM WATER PLANS help ensure that community water systems
reduce their vulnerability to drought and are prepared to respond to potential water shortage conditions.

Community water systems are required to submit a System Water Plan update every five years. (ARS §45-342). The system water plan includes a water supply plan, water conservation plan, and drought preparedness plan.

How does Conservation Prepare Communities for Drought?

Planning for future water needs includes conservation as well as augmenting water supplies. This may reduce the chance of declaring an advanced stage of drought and the need for emergency sources of water.

  • By using less water each day, water supplies can be stretched or banked for future use.
  • Using less water overall extends the life of water treatment plants and delays the costs of enlarging facilities or drilling new wells.
  • Conserving water results in more water to go around. To conserve water:
    • Find and fix leaks to save thousands of gallons of lost water.
    • Use rainwater, graywater or reclaimed water to water plants.
    • Plant low water use plants -- - they tolerate water shortages much better than high water use plants, so you won’t have to water as much.
