Our Services
Phoenix Water Services delivers safe, reliable water and wastewater services to over 1.7 million customers by managing a sustainable network of resources. Our water supply draws from a diverse mix of sources, including the Salt, Verde, and Colorado Rivers, allowing us to prioritize surface water while reserving groundwater for critical needs. Phoenix's advanced water treatment facilities ensure that every drop meets the highest quality standards before it reaches your tap. Our wastewater system efficiently treats, recycles, and repurposes water, supporting environmental health and sustainable reuse for agriculture, energy production, and river replenishment. Through careful management, we provide essential services that protect public health and preserve water resources for generations to come.

2 Production wells are a type of well that only pump water from underground
3 Storage and recovery wells have the ability to store water underground and pump for use later on
4 We do not strongly rely on well water, since 98% of our water supply comes from surface water which meets our current demand
5 Groundwater is used sparingly to save it for times of drought
