Document Description
The project would construct and operate additional wastewater treatment infrastructure at the existing Regional Treatment Plan and construct a new parking and laydown area adjacent to the RTP’s primary access road. The treatment infrastructure site is approximately 1.1 acres, and the parking and laydown area is approximately 0.7 acres. The proposed treatment facilities would connect to the RTP’s Advanced Water Treatment system to further treat recycled water produced and reduce its total dissolved solids content. The 0.7-acre parking and laydown yard is located east of the proposed treatment facility. It would be paved and feature drainage improvements and a driveway connecting to the existing RTP access road.
