Description

The St. Mary Parish Water & Sewer Commission No. 4 seeks sealed bids for a comprehensive water‑system consolidation improvement project. The effort will modernize, expand, and interconnect existing water distribution infrastructure within the parish, addressing capacity, reliability, and regulatory compliance. The bid package includes detailed plans, specifications, and civil‑engineering drawings that encompass a broad scope of construction activities. • Design‑build or separate‑contract approach for water mains, pipelines, valves, and related appurtenances. • Required earthwork, trenching, back‑filling, and site preparation across multiple public right‑of‑ways. • Installation of new water‑treatment facilities, storage tanks, and pressure‑regulating stations as indicated in the project plans. • Coordination with existing utility services, traffic control, and compliance with local, state, and federal environmental regulations. • Deliverables include as‑built drawings, testing & commissioning reports, and a warranty period for installed infrastructure.

Budget estimate

$5,000,000 – $15,000,000

The project involves extensive civil construction, pipe installation, and water‑treatment upgrades across a parish‑wide network. Comparable municipal water‑system consolidation projects in Louisiana typically range from $5 million to $15 million, depending on pipe diameter, length, terrain, and ancillary facilities. Therefore, a reasonable earnings estimate for a contractor handling the full scope would fall within that band.
