Durward Well Developing & Equipping

Puente Basin Water Agency

The Durward Well Development & Equipping Project is a vital initiative aimed at providing a new local groundwater source for the region, reducing reliance on imported water. Managed by the Puente Basin Water Agency in partnership with Rowland Water District and Walnut Valley Water District, the project involves constructing a new well capable of supplying 1,000 gallons per minute. The well connects the Pomona-Walnut-Rowland Joint Water Line, where its water will be blended with existing sources to enhance supply reliability.

Civiltec Engineering has led the design, planning, and construction oversight for the project, with David Song, PE, serving as the Project Manager. The well is designed to reach 850 feet deep, equipped with a 16-inch stainless steel casing and a 150-horsepower pump to ensure consistent water production. Timothy Kwan, PE, played a key role in designing the system, which includes a 10-inch discharge pipeline to integrate the well into the regional water network and a 16-inch flush-to-waste pipeline for maintenance. The project also incorporates advanced automation, including a SCADA system for remote control and monitoring and a soft starter for efficient operation.

To maintain high water quality, Civiltec incorporated cement annular seals and bentonite barriers to prevent contaminants such as nitrate, VOCs, and perchlorate from entering the water supply. The team conducted aquifer tests to identify the best extraction points, ensuring the well produces clean and safe drinking water. Reflecting on his experience, Timothy Kwan shared that witnessing the well pump testing was a highlight of the project. “I spent a while working on this project, so seeing it come to life felt incredibly rewarding. It confirmed that everything I did contributed perfectly to helping the community.”

With rigorous engineering, strategic planning, and cutting-edge technology, Civiltec is proud to be a part of the Durward Well Project. Proving the well to be a reliable, sustainable, and cost-effective water resource, strengthening the region’s water infrastructure for years to come.
