Evoqua’s Water Treatment Tech Helps City Address Water Supply Challenges

activated carbonEvoqua Water Technologies will provide its water treatment technologies and services to the city of Paso Robles, California, as the city attempts to overcome water supply challenges due to the state’s ongoing drought.

In the past, the city relied entirely on groundwater, drawn from a large aquifer. To diversify its water supply, the city launched the “Lake Nacimiento Water project” and secured a supplemental 4,000 acre-feet per year water entitlement. The use of the Lake Nacimiento water will enable the city to reduce its dependency on the Paso Robles Groundwater Basin, and provide a reliable long-term water supply.

The city selected Evoqua Water Technologies to design, manufacture and install a granular activated carbon adsorption system as a part of the new water treatment plant.

The treatment plant will utilize Evoqua’s UltraCarb 1240AW granular activated carbon media to treat the Lake Nacimiento water supply for removal of total organic compounds. By using this advanced carbon, the city of El Paso de Robles expects to treat more water per pound of carbon than would otherwise be possible using standard coal-based carbons. This will reduce the life cycle cost of treatment and save the Paso Robles and its water users money.

Evoqua supplied two custom built HP Series 1220SYS adsorption systems. The ASME code-stamped 12-foot diameter 20,000-pound media capacity vessels are carbon steel, lined and manufactured/assembled at Evoqua’s Red Bluff, California, manufacturing facility.

In December, Evoqua participated in the White House’s Roundtable on Water Innovation, along with other industry and public leaders, to discuss how to plan, efficiently use, and develop new supplies of clean water.
