Subject

Resolution 2018-16 Agreement with Rye Engineering for Water System Leak Detection Services.

Background

The Water Services Department budget for FY 2018 includes water distribution system leak detection services associated with the department’s ongoing water loss reduction efforts. Leak detection is an integral part of department efforts to reduce water. Leak detection services offered by Rye Engineering include acoustic detection of escaping water from pipes, valves, hydrants and other system appurtenances. Rye technicians use advanced listening devices to pinpoint leaks and prioritize leaks based on size and estimated loss volume.

In FY 2017, Rye Engineering completed leak detection services in the water system’s north pressure zone, or about 50 pipe miles of coverage (20% of the distribution system). The work resulted in detection of 10 pipe leaks estimated at about 1.5 millions gallons of water loss per month (see attached summary report).

The next phase of leak detection services includes coverage of the remaining distribution system or about 175 miles of pipe. Rye reports their findings to the Water Department staff and staff then prepares prioritized work orders for repairs of the leaking facilities. Accordingly, Rye has a submitted an engineering services proposal for this work in an amount not to exceed $31,875.00 which includes a 10% contingency allowance. This contract amount is within the budgeted amount included in the department’s FY 2018 budget and therefore, staff recommends approval of the attached agreement.

Should you have any questions, please contact Chris Milton, Director Water Services.
