As cities across the Southwest face mounting water challenges, Phoenix is taking strategic action to safeguard its drinking water supply. A recent Opflow article highlights the City of Phoenix’s latest investment in drought resilience: the 4A-B10 Booster Pump Station (BPS). Designed by Carollo, this new facility is a key component of the city’s Drought Pipeline Program, making it possible to deliver water from the Salt and Verde rivers where it’s needed most—especially during shortages on the Colorado River.
Addressing Drought Challenges with Smart Infrastructure
Long before restrictions on the Colorado River took effect, Phoenix proactively secured additional water resources to reduce its dependence on a single source. The 4A-B10 BPS allows the city to move treated water from the 24th Street Water Treatment Plant to its northern pressure zones via a 66-inch transmission main. The facility is also designed for flexibility: in the event of changing water demands, it can send water back south to balance supply across the city.
Strengthening Water Distribution for a Changing Climate
Built with efficiency and long-term sustainability in mind, the booster pump station includes six high-capacity vertical turbine pumps, with space for future expansion. To maintain stable operations, the facility features two 50,000-gallon surge tanks to manage pressure fluctuations, as well as advanced water quality testing and modeling to aid in a smooth transition to this new water source.
Investing in a Secure Water Future
This project is more than an infrastructure upgrade—it’s an investment in Phoenix’s long-term water security. Thoughtful design, rigorous planning, and a commitment to resiliency helps the city remains prepared for future water challenges.
