Treatment Plant Expansion

 

We are currently in the process of expanding our 9.6 mgd Oliver P. Roemer Water Filtration Facility. 

Phases I and II have been completed.

 

Phase I: Expanding the facility from 9.6 mgd to 14.4 mgd.  This will include UV disinfection for Crypto and Guardia to meet future LT2 surface water treatment regulation.

 

Phase II: This will allow the plant to treat 14.4 mgd of State  Project water using enhanced coagulation to achieve at least a 35% reduction in TOC and to treat 6.0 mgd of Lytle Creek water for particulate (china clay) removal to assure full utilization of this high quality water supply.

 

Phase III: This will expand the plant from 14.4 mgd to 20.4 mgd with the installation of a 6.0 mgd Membrane Plant.
