Water Department & Reservoir Emergency Power
The City of Moscow water distribution system depends on the operation of electrically powered pumps to supply drinking water from the City wells to the water towers and finally to the City of Moscow residents. In short-duration outages the storage in the water towers can provide drinking water, but in longer duration outages such as the outage experienced Friday, May 5th the pumps may need to operate using the emergency generators to supply power. Currently, in this situation, the Moscow Water Department Facility provides the majority of the water supply. The emergency power generator that is currently located at the Water Works Facility is barely sufficient to meet the demand created by the pumps and needs to be upsized. In addition, the emergency power needs at the Southeast Reservoir are being met by a portable generator which needs to be controlled manually.
This project will provide permanent stand-by power generators with automatic reset for both the Moscow Water Department Facility and the Southeast Reservoir. These generators will ensure that in the case of a longer power outage the City of Moscow residents will continue to have water both at their homes for consumption and at the hydrants for fire protection.
The contract for the emergency power project was awarded to Gropp LLC of Moscow, Idaho. The contractor began preparing the sites at the beginning of May with the generators expected to arrive in the middle of June. The project is expected to be complete by the end of July.
Construction Update - September 4, 2017
The generator at the Southeast reservoir has been installed and wired and is ready for its initial startup. Western States Equipment and Trindera Engineering will be in Moscow to support the initial startup and ensure that the generators are functioning properly.
The old generator has been removed at the Water Treatment Plant and the new generator has been installed in its place. Gropp Electric is finishing up the final connections and then the generator will be ready to test and startup.
- Domestic Flow - The amount of water supplied for everyday domestic use, such as for sinks, showers, toilets, etc.
- Fire Flow - The amount of water supplied to firefighting equipment by a hydrant connected to the water distribution system.
- Redundancy - Having more than one water main or pump supplying a development or neighborhood so that one component can be shut down for repairs while the other one still operates to serve that development or neighborhood.
