Water and Wastewater Storage Experience

Paso Robles Tank builds steel tanks that hold potable water, greywater, and sludge for utilities across California. That work has earned repeated national recognition from STI/SPFA, including the Holly Drive Steel Tank Reservoirs in Upland, named a 2023 Tank of the Year, and the Dalton Reservoir Replacement in Livermore, a 2020 Tank of the Year.

Our work spans new reservoirs, replacements, and structural upgrades to tanks already in service. The Jamestown Reservoir Replacement Project took the STI/SPFA 2018 Tank of the Year, and the Washwater Tank Seismic Improvements in Rancho Santa Fe earned the STI/SPFA 2023 Tank of the Year Product Award for Repair and Modification. Whether you need a new reservoir or seismic reinforcement for an existing tank, our team manages the project from design through startup so the finished tank protects your water supply for decades.
