ATEC Water Systems to supply filters for Utah groundwater project

Under the contract, ATEC will manufacture a total of 320 filters for the project at its facilities in Hollister, California over the next 12 months. This is the largest contract in ATEC's history.

The Vineyard Wellfield Groundwater Polishing Project is a treatment facility that will deliver 60 million gallons per day (MGD) or approximately 54,000 acre-feet per year of clean groundwater to central Utah communities.

"ATEC’s filters are the most innovative, effective and affordable solution for groundwater treatment on the market," said Scott Slater, CEO of Cadiz and president of ATEC. "We are pleased to be supporting the Central Utah Water Conservancy District in this exciting project to make groundwater available as a reliable source for their communities.”

Although the water from the area meets or exceeds primary and secondary drinking water standards, some of the wells contain elevated levels of manganese, iron, ammonia and hydrogen sulfide which can lead to discoloration of and particles in the water. The ATEC filters will remove or reduce these constituents to optimize the use of groundwater from the CWP in Vineyard. Pilot testing of the ATEC filter and media on Vineyard groundwater was successful at removing and reducing the constituents of concern.

“Impaired water systems and groundwater contamination are a global threat,” said Susan Kennedy, Cadiz executive chair. “ATEC filter systems gives Cadiz critical new tools to augment water supply for communities in a changing climate.”

As ATEC's filters are manufactured, they will be delivered to the Vineyard treatment plant, tested on site, and then installed by the project's general contractor overseeing construction of the facility. ATEC staff, in coordination with CUWCD, will monitor and track the long-term performance of the filters once the treatment plant is online.
