Water main installation is nearing completion. Once everything is installed, the contractor will perform a pressure test. For the test, 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. Contractor is going to start on storm sewers while waiting for the water main testing.
