Grinder Pump Replacement Services

The St. Mary's County Metropolitan Commission is issuing Invitation to Bid (ITB 26-13-F) for grinder pump replacement services at residential locations throughout St. Mary's County, Maryland. The scope of work encompasses the complete removal of existing sewage grinder pumps and vaults, installation of new pumps and vaults, reconnection to existing service lines and pressure mains, installation or replacement of electrical conduit and wiring, and connection of control panels to grinder pump components. Bidders must provide complete pricing for all 14 line items, including installation of seven-foot and seven-foot-one-inch to twelve-foot grinder pumps, conduit and wiring installation, isolation valve and box installation, select backfill, washed gravel, and pumping of waste from vaults. The Commission estimates replacement of approximately 30 to 50 grinder pump units annually, though no minimum quantity is guaranteed. All electrical work must be performed by a licensed electrician, subcontractors are compensated at actual cost plus 10 percent, and all work must be warranted for one year from completion. Sealed bids are due by 3:00 p.m. Eastern Time on April 30, 2026, at 23121 Camden Way, California, Maryland 20619, with the bid opening scheduled for the same date and time. Requests for information must be submitted by April 16, 2026, at 12:00 p.m. Eastern Time. The contract will be awarded to the lowest responsible, responsive bidder providing the best value based on evaluation criteria including price, quality of goods or services, bidders' previous experience on relevant work, and location of the bidder relative to emergency response time.

The contract commences upon approval and execution of the agreement, with three optional one-year renewal periods available by mutual consent, and pricing may be extended based on the Consumer Price Index with Commission approval. A performance bond of $100,000 is required within ten days of award. The Commission supplies all grinder pumps, vaults, risers, vault extensions, control panels, and valve boxes, eliminating the need for bidders to procure these materials. No specific set-asides for disadvantaged enterprises or restrictions on organizational type are mentioned in the procurement documents. The contract does not specify an incumbent vendor or current contractor, suggesting this may be a new contracting initiative or a re-competition. While no explicit award value or budget range is provided in the documentation, the estimated annual volume of 30 to 50 grinder pump installations combined with the performance bond requirement of $100,000 indicates a substantial contract opportunity. The Commission reserves the right to reject any or all bids and to award the contract based on factors other than lowest cost.
