Annual Purchase of Water and Wastewater Treatment Chemicals

The City of Rosenberg, Texas is requesting bids for the annual purchase of water and wastewater treatment chemicals under ITB #2027-14B, with sealed bids due November 5, 2026 at 2:00 p.m. and a question deadline of October 30, 2026 at 5:00 p.m. Bids must be submitted electronically through the OpenGov Procurement portal and will be publicly opened at City Hall.

The procurement covers three chemicals in specified volumes: sodium hypochlorite 12.5% (30,155 gallons), liquid ammonium sulfate 40% (5,949 gallons), and liquid poly-ortho phosphate blend 70/30 (1,695 gallons). Delivery is required to multiple treatment plants within Rosenberg — one surface water plant, six groundwater plants, and a reclaimed/reuse station — with deliveries due within three business days of order placement between 8:00 a.m. and 4:30 p.m. All chemicals must conform to ANSI/NSF 60 standards and applicable AWWA specifications. Vendors must submit product samples for independent laboratory analysis at their own expense, provide certified manufacturer's laboratory reports with each delivery documenting lot number, manufacture date, and chemical composition, and supply minimum five references from municipal or government water treatment clients within the past five years. Vendors are responsible for all delivery equipment, unloading operations, hoses, fittings, and pumps, as well as spill cleanup from their negligence. Three failures to meet specification, delivery, or documentation requirements constitute grounds for purchase order termination.

The initial contract term runs October 1, 2026 through September 30, 2027, with potential renewal for four additional one-year terms. Pricing must be firm for year one; price adjustments in subsequent years are capped at 2.5% annually based on the Houston-The Woodlands-Sugar Land Consumer Price Index and require 60 days' notice with supporting documentation. All pricing must include delivery and freight (FOB Rosenberg), and vendors must submit published OPIS pricing sheets supporting quoted unit prices. The City is exempt from state and federal sales and excise taxes and will award to the lowest responsive and responsible bidder. Vendors must maintain workers' compensation and liability insurance with minimum $500,000 per occurrence for general and comprehensive automobile liability, and must complete certifications regarding anti-boycott, anti-terrorism, and COVID-19 vaccination policies.
