H2O Innovation Designs Water Reuse System for Dry California City

by | Sep 9, 2015

H2O Innovation will design and build a water reuse system for another dry California city — Carlsbad — during the state’s ongoing drought, the water treatment company says.

The ultrafiltration system will have a 3 MGD (11,356 m3/d) capacity and will treat the effluent of the Encina Water Pollution Control Facility. The filtrate water will then be used for non-potable water applications such as irrigation and certain industrial applications.

This design-build project will be the third expansion of the Carlsbad Water Recycling Facility and will receive financial help provided by the state.

The Carlsbad installation is among H2O Innovation’s new contracts in the US and in Canada with a total value of $7 million. Of the contracts secured in the last few weeks, two of them consist of the design, manufacture, delivery and commissioning of drinking water systems for municipalities located within the US.

The Sweetwater Authority in California, located near San Diego, has selected H2O Innovation to expand its desalination plant, which was built by the company in 2000. The existing system produces 4 MGD (15,141 m3/d) of drinking water and will be increased to 5 MGD (18,927 m3/d) with the addition of three reverse osmosis trains treating brackish water. This system expansion will benefit the cities of Bonita, Chula Vista, and National City, which are all affected by the drought in California.

Additionally the city of Arkansas in Kansas also contracted H2O Innovation to replace its existing lime softening system used for the production of drinking water. A new four trains RO system will be installed to produce 3 MGD (11,356 m3/d) of drinking water from groundwater. The manufacturing of this system is preceded by a 45-day piloting period to validate the treatment scheme.

Finally, the Company will design, manufacture, deliver and commission a new membrane bioreactor (MBR) system to be installed in the province of Quebec. This wastewater system of three trains will treat 36 GPM (196 m3/d) of wastewater. This is the company’s first wastewater project in Quebec.
