7. DISCUSSION and BACKGROUND
The 27" diameter transmission main was installed in 1957 to convey water between pressure
zones 2 and 3 of the water system. This is a steel pipe with cement lining on the inside and
outside of the pipe. A leak on this transmission line was reported and investigated by Water
Division staff. Because of the pipe material, the repair required the expertise of an outside
contractor.
Valverde Construction, Inc. was contacted because of their experience repairing this pipe
material. They have successfully repaired leaks at other locations for the City in the past. Their
workmanship and reasonable pricing has proven beneficial to the City. Valverde Construction
proceeded to repair the leak on a time and material basis under the supervision of the Water
Division. Work was done around the clock in coordination with SCE due to the required street
closure to accommodate equipment and safety measures. After completion, time and material
tickets and an invoice were submitted to the City in the amount of $37,806.
The repair work has been completed and the waterline is back in service. Staff is requesting the
authorization to make final payment to Valverde Construction, Inc. The cost paid to Valverde
Construction along with staff time involved in reparing the leak will be submitted to SCE for
reimbursement based on evidence that the leak was caused by the installation of the power pole.
Due to the nature of the leak, the City did not have time to conduct a bid process and seek prior
City Council approval of this contract.
