About this file

This is a chemicals specification document related to water treatment services for the Washington Suburban Sanitary Commission (WSSC) in Maryland. The file contains detailed chemical requirements for HVAC and biosolids treatment systems across eleven WSSC facilities. The contractor must provide comprehensive water treatment services including all necessary chemicals, supervision, labor, equipment, materials, and tools to maintain proper operating conditions across the designated systems. Sealed responses must be submitted via WSSC's eProcurement Portal at https://procurement.opengov.com/portal/wsscwater no later than 2:00 pm on Monday, August 3, 2026, with late submissions not accepted. The scope encompasses both mechanical and water systems requiring specialized chemical treatment to meet operational and regulatory standards.

The chemicals specification document outlines the specific chemical products, formulations, and quantities required for the contract performance. These specifications establish the baseline requirements and standards that bidding contractors must meet or exceed in their proposals. The document serves as a critical reference for contractors to understand the technical requirements and chemical treatment protocols necessary to successfully perform water treatment services at all eleven WSSC locations, ensuring compliance with applicable water quality and system maintenance standards.
