Well 10 Connection​

Last summer Boart-Longyear drilled 991 feet and installed the 24 inch diameter well casing for the City of Moscow Well Number 10 at the West edge of 'A' Street. This well was drilled into the Grande Ronde Aquifer, which is the deeper of the two aquifers available to the City of Moscow, and will provide higher quality water requiring less treatment.

Project Overview

The Well Number 10 Connection project will install approximately 800 linear feet of ductile iron water line that will connect the existing 16-Inch water line in 'A' Street to the existing 12-Inch water line in the Palouse Mall Parking lot that currently connects Well Number 9 to the City of Moscow distribution system. This connection will allow the Well Number 10 site, once completed, to contribute drinking water and provide redundancy that will ensure the City of Moscow can continue to provide water even if one of the wells must be shut down for repairs or maintenance.


The contract for the Well Number 10 construction project was awarded to Sandry Construction, Inc. from Spokane, Washington. Timeline for construction is currently being established.

Construction Update - September 4, 2017

Sandry Construction has completed the installation of the water line. The City of Moscow Water Department is disinfecting and testing to ensure that the line will be ready to connect once the Well Number 10 site is developed.


  • Fire Flow - The amount of water supplied to firefighting equipment by a hydrant connected to the water distribution system.

  • Water Well - A water well is an excavation or structure created in the ground by digging, driving, boring, or drilling to access groundwater in underground aquifers.
