Claremore completes 2,200‑foot gravity sewer rehab under CDBG grant; final change order approved

Council received a final report on a gravity sewer rehabilitation project that replaced fragile clay tile lines across segments of the city and used a 2023 Community Development Block Grant (CDBG) small‑city award for funding. The project targeted aging sanitary sewer segments and included manhole work, service taps, and repairs.

The project matters because the city described the sanitary sewer collection system as Claremore’s top infrastructure concern; staff said addressing failing gravity lines reduces infiltration and inflow to the wastewater plant and lowers the risk of residential backups and liability claims.

Staff said Horseshoe Construction of Texas was the contractor. The city performed design, surveying, project management, inspection and some CCTV work in house; the Community Development Department handled CDBG grant management. The contract was awarded in April 2024 at about $520,000; final deduct change order totaled approximately $11,007.34 and the final project cost was reported near $510,000. Staff estimated roughly $220,000 in savings from the city’s in‑house work. Work items included about 2,200 linear feet of gravity sewer rehab, two manholes replaced, 11 manholes rehabilitated, one lamp/pump(?) rehab, 52 service taps placed and 27 repairs completed; the primary construction method was pipe‑bursting with high‑density polyethylene liners.

Staff showed before‑and‑after CCTV and photos of collapsed clay‑tile segments and noted the project was on schedule and under budget. Public complaints were minimal, staff said. The final deduct change order for Horseshoe Construction was presented and approved by motion during the meeting.

Ending: Staff said the work reduced inflow and infiltration at the plant and that more system upgrades will be needed across the city; the city will continue to pursue grant funding for further sewer work.
