The water delivered to your home travels more than 150 miles through mountain and desert terrain before it emerges from your tap.


High in the mountains of northern and eastern Arizona, the water that flows from your tap begins as snowflakes in a winter storm.

When springtime temperatures rise, that snow begins to melt.

And then its journey begins — an adventure through wilderness and forests to an SRP reservoir system that provides water, and life, to our desert community.


Melting snow first collects in small streams as it cascades down mountainsides, flowing into tributaries and then into the Salt and Verde rivers.

SRP hydrologists measure not only the snowpack, but also the flow of water to determine how much water will be available each season. They also determine how much may be needed from other sources, such as groundwater pumped from wells in the Phoenix area.






Valley cities accept water from SRP's delivery system at their water treatment plants. SRP’s water system can also deliver other sources of water, including water from SRP wells, the Colorado River and municipal wells. This diversity of sources ensures a reliable water supply is available under a variety of conditions.

City water treatment plants purify the water to ensure it meets all federal and state water quality standards and deliver it via a series of underground pipes directly to your home.


Water enters your home through your municipality's distribution network, providing water for the essentials of daily life.

Outdoor uses consume the largest percentage of SRP water. Some of this is captured by evaporation, which sends water back into the atmosphere where it will fall as rain again elsewhere.

The water you use indoors is recaptured from the drains in your sinks, baths, showers, toilets and washing machines.


Water that goes down any drain in your home is delivered to your community's wastewater treatment system.

The sewage is highly treated to remove solids and impurities. This reclaimed water can be used for beneficial purposes including irrigation for parks and golf courses, at Palo Verde Nuclear Generating Station, for agricultural purposes or to recharge Valley aquifers.
