This project will improve the water storage capacity at the Power Plant. A new 120,000 gallon capacity RO permeate storage tank will be added. A pre-purchased RO module skid unit and water softener skid unit will be installed in a new pre-engineered pre-framed panelized building. This project includes an extension of an existing underground tunnel for access from the new building. All required structural, electrical, plumbing, heating, and ventilation connections from the existing building to the new structure are included in this project.
