Biwater Explores New Source of Water


Biwater to Provide Indirect Potable Reuse Solution for Padre Dam Municipal Water District in California 

Biwater will provide a complete turnkey design, and supply and commission all process, mechanical, electrical and control components for the plant.

The project is  to include: Field pumps, a chlorine contactor, chemical dosing systems, ultrafiltration system, reverse osmosis system, advanced oxidation process system (using ultraviolet light (UV) and oxidation), programmable logic controller (PLC) and instrumentation, motor control centres and electrical panels.

Biwater was chosen for its ability to supply a fully integrated system on a fast-track delivery.

The new facility will treat secondary effluent from a wastewater treatment plant in the District, and the treated water will be used for demonstration and testing purposes, to ensure it meets or exceeds the California Public Health Department’s draft regulations.

“This innovative project will see the Padre Dam District set new benchmarks for water reuse, and enable it to create a reliable source of water, underpinning East San Diego County’s economy and future prosperity,” said Jorg Menningmann, President, Biwater Desalination and Membrane Treatment Sector.

Following commissioning, the demonstration project will run for a period of one year. In parallel, studies will continue to assess the capacity of Santee basin aquifer and the feasibility of extending the project beyond the demonstration and testing period, to serve a larger customer base in California.

After the testing period, the District hopes to be able to expand the facility, to construct a full-scale plant to provide up to 10 million gallons per day (US) of treated water with indirect potable reuse potential. With the necessary approvals to proceed, treated water would be injected into the local groundwater basin.
