WATER RESOURCES

Water is a vital resource for life and it is especially important here in the arid southwest. Having a long-term water supply is an essential part of sustaining economic health. The City's water service area has been awarded the Designation of Assured Water Supply and has demonstrated the availability of a 100-year water supply based on current and future demand projections. 

It is important to preserve our groundwater resources. Currently the City's drinking water all comes from pumped groundwater. We use a mix of Central Arizona Project surface water and treated wastewater to replace the water we pump to ensure we have a sustainable source. 

The City of El Mirage is a proud partner of WUIW

WASTEWATER QUALITY

WWTP

The City operates a wastewater reclamation facility that treats an average of 2 million gallons a day of wastewater from our system. Once cleaned we recharge the water into the ground for future use. We constantly test and monitor the output to ensure the water we store is clean and safe for the environment.

Blockages in our sewer system can cause headaches for both residents and the City. Do your part to help protect our collection system.
