The contractor is pulling the last section of water main pipe and will be making the connection to the existing water main. This connection is scheduled for Monday weather permitting which will require a water shutoff for 6 – 8 hours. Residents should receive notices on their doors today. After the connections are made, the contractor will install the fire hydrants. Then the water main will need to be pressure tested. It’s actually quite a simple test, in that the main is filled with water and pressurized to 150 pounds per square inch (psi). To pass the pressure test, pressure must be held at 150 psi for 2 hours. Once the pressure test passes, the water main gets chlorinated. Once the chlorination tests pass, the contractor can begin on water services.
