Executive Summary The city operates 12 sewer lift stations that pump wastewater flow uphill to higher elevations in the sewer collection system. These stations use flow meters to measure sewer flow and to monitor lift station operation. The flow meter at the Cannon Lift Station, located at 2197 Cannon Road, as shown in Exhibit 3, is at the end of its service life and requires replacement. The estimated construction cost including contingency, construction management and inspection, public outreach, and engineering and administration is $983,500. The City Council’s approval of these plans, specifications and contract documents is required under Carlsbad Municipal Code Section 3.28.080(E) because the expected value of the work exceeds $200,000.
