Report
Summary
Significant sewer improvements over the past 10 to 15 years have warranted the need to recalibrate the City sewer model. The original Mega Metering project scope included installation of 170 portable sewer meters, water flow monitoring for 30 days, and use of flow meter data to fully calibrate the sewer model.
The revised scope of work includes installation of an additional 44 portable sewer meters, performing field investigations to verify system schematics, providing additional portable metering services to verify the accuracy of WSD permanent meters, and quantifying the diversion of flow from various split manholes. The data gathered from each meter location will confirm or allow for adjustments of flow rates within the expected range for that meter’s location.
Contract Term
The contract term remains at one year, ending on June 30, 2018.
Financial Impact
With the one-time addition of $211,881.42, the revised aggregate contract value is now $831,131.82. Funds are available in the Water Services Department's Capital Improvement Program budget.

This contract is the result of Solicitation 84-16-102-RFP-8442, awarded by City Council (Payment Ordinance S-43663) on June 21, 2017, with an original aggregate value of $619,250.40.
