Vault Pumping and Septic Service at Silver Lake State Park

The Michigan Department of Natural Resources is issuing a Request for Proposal (RFP 260000001382) for vault pumping and septic system maintenance services at Silver Lake State Park in Mears, Michigan. The procurement seeks a qualified contractor to provide comprehensive waste removal and disposal services for eight vault toilet facilities containing 13 vaults ranging from 600 to 1,200 gallons and seven septic tank locations with capacities between 1,000 and 5,000 gallons. The estimated annual service requirement is approximately 34,200 gallons, with vault toilet pumping frequencies varying from once to twice annually and septic tank services ranging from annually to once every three years. Deliverables include all pumping operations, equipment provision, labor, waste disposal, and transportation services required to maintain these facilities, with pricing submitted on a per-vault unit basis for toilet facilities and per-1,000-gallon basis for septic tanks as a single firm price for a 365-day period. The contractor must hold a Michigan Department of Environmental Quality license to remove and transport septage waste in compliance with Part 117 of the Natural Resources and Environmental Protection Act and must maintain commercial general liability insurance with minimum limits of $2,000,000 general aggregate and $1,000,000 per occurrence, along with automobile liability and workers' compensation coverage. Key deadlines include a bidder questions deadline of March 16, 2026, and a proposal submission deadline of March 23, 2026 at 3:00 p.m. Eastern Time, with an anticipated contract commencement date of April 1, 2026 and a three-year initial term with options to renew for up to two additional one-year periods at the State's discretion.

The RFP does not specify set-aside designations or restrictions limiting competition to particular enterprise types, meaning this opportunity appears open to all qualified bidders meeting the licensing and insurance requirements. No incumbent contractor or existing infrastructure integration requirements are identified in the available documentation. Pricing adjustments during the contract term are permissible only through written requests supported by documentation of actual cost changes and are subject to mutual negotiation between the parties. Liquidated damages of $1,000 plus $100 per day are assessed for late or improper completion of services, and payment will be made via Electronic Funds Transfer within 45 days of invoice receipt. While a specific award value or budget range is not disclosed in the RFP materials, the scope of services and estimated 34,200 annual gallons of combined pumping capacity provide a basis for bidders to develop competitive pricing proposals.
