Capital Improvement Project


Cobblestone Dr Zone R2-R4 Water Main Connection

Estimated Construction Schedule: Slated to begin April, 2023 and is anticipated to be completed November, 2023.
Construction Contract Amount: Pending
Project ID #: 1999
Description: The Project will install approximately 1,045 linear feet of new 10-inch diameter water main and a pressure-reducing assembly that will connect a high-pressure zone with a lower-pressure zone to improve fire protection in the Cobblestone neighborhood. Approximately 174 linear feet of 8-inch diameter water main will be added near the southern end of Cobblestone Drive to provide operational flexibility including the ability to isolate the Cobblestone neighborhood into a separate pressure zone.

Construction Update Image

August-September, 2023: The majority of the work is now complete (8-24-23). The high pressure zone has been connected to the low pressure (Cobblestone) zone. Now, if your neighborhood experiences a low pressure situation, for example, if a fire hydrant is opened, the new pipeline pressure reducing valve will fully open to supply the large amount of water and pressure that my be required to fight a fire. This is a huge safety improvement to your neighborhood that hopefully you will never need, but if you do, it is there. Additionally, the system has been set to provide a small increase in your daily water pressure from what it was previously. The new water pressure is enough to be noticeable and is generally considered preferrable by customers.
