Title
Authorize the City Manager to Issue a Purchase Order to USSI, LLC in the Amount of $218,400 for the Smoke Testing of the City’s Wastewater Collection System by Piggybacking on Clearwater Contract No. 22-0006-UT - Jeffrey E. Poteet, General Manager, Water & Sewer
Body
BACKGROUND:
Smoke testing is an easy, cost-effective way of locating leaks in the collection system with little disruption to the City’s sewer customers. An additional advantage to this method of investigation is that it will not only test the City’s maintained gravity main pipes but will also test the integrity of the sewer laterals. This method has been used extensively all over the country for over 40 years to locate defects in sewer systems.
Damaged pipes, improper private sewer construction or illegal connections to the sewer offer an easy route for storm water or other non-wastewater discharges to enter the sanitary sewer collection system. Non-wastewater flows entering the sanitary sewer collection system not only takes up valuable capacity (which could potentially cause raw sewage spills), but costs extra money to treat and convey.
Since the wastewater collection system is underground and is constantly subject to the forces of nature, dynamic changes can occur in relatively short periods of time. Those forces of nature may be heightened because Marco Island is a barrier island whose soil is primarily made of sand. Sandy soils are loosely packed so when it rains these soils shift and compact more easily, causing pipes in the ground to fail. All equipment necessary for the collection/transmission of domestic wastewater, including equipment provided, pursuant to Rule 62-604.400(2), F.A.C., shall be maintained to function as intended.
Pursuant to City of Marco Island Purchasing Ordinance, Section 2-255(c)(3), the purchase of goods and services available from federal, state, or local government agency existing contracts can be piggybacked. USSI, LLC has been selected by piggybacking on the City of Clearwater Contract No. 22-0006-UT.
This project will smoke test 455,000 linear feet of gravity main at a cost of $0.48 per linear foot for a total cost of $218,000. This cost includes smoke testing all areas of Marco Island and a detailed report with the findings. Staff will use this report to identify issues in the system and prioritize deficiencies so the Collections and Distribution Department can make proper repairs.
FUNDING SOURCE / FISCAL IMPACT:
Funding for this Purchase Order is in the approved FY25 W&S C&D Operating Budget (Fund 400) under GL account 4005361-523400. The project is short of $80,000 due to a price increase from $0.32 per linear foot last year to $0.48 this year. The necessary funds will be obtained from GL 4005363-253100, which has a remaining balance of $150,000 allocated for the Lead and Copper Revision Rule Survey budgeted last year. However, the LCRR survey will now be performed under the Advanced Metering Infrastructure Contract, therefore, these funds are no longer needed.
RECOMMENDATION:
Authorize the City Manager to issue a purchase order to USSI, LLC for the Smoke Testing of the City’s Wastewater Collection System in the amount of $218,400.
POTENTIAL MOTION:
“I move to Authorize the City Manager to issue a purchase order to USSI, LLC for the Smoke Testing of the City’s Wastewater Collection System in the amount of $218,400.”
