Water Treatment System Upgrade Project

Water Treatment System Upgrade Project

The Project is proposing to improve and replace an existing water distribution system that currently serves 34 residential connections in the unincorporated area of Orleans. The Project would demolish an existing in-line filtration plant and replace it with a new surface, direct-filtration WTP. The Project would construct a new water treatment building with a backwash reclaim tank. A proposed generator and propane tank would be located adjacent to the water treatment building. The existing in-line filtration plant would be replaced due to age, deteriorating condition, outdated composition of the existing system, lack of system redundancy, and insufficient reserves to support fire response flows. The Project would also demolish an existing redwood raw water tank and replace it with a new bolted steel water storage tank. Implementation of the proposed Project would increase water storage capacity and/or operational capability of the overall system. The proposed improvements have been sized to provide for system redundancy and calculated fire flows without additional residential service connections that are non-growth inducing. All components of the Project are described in more detail below. Refer to Figure 3 for a Site Plan of the proposed Project.
