About this file
This document is a standard details reference guide for corrosion control specifications issued by the Washington Suburban Sanitary Commission (WSSC) in Maryland. The file serves as a technical standard manual for water infrastructure projects and contains comprehensive tables of contents and detailed drawings for corrosion prevention and protection measures related to water main construction and connections. The document covers approximately 59 standard detail specifications organized into seven major sections addressing ductile iron pipe bonding, thermite welding, sacrificial anode installation, insulated flange joints, test stations, field-applied coatings, and PVC pipe anode protection systems. These standards apply to the construction of water house connections ranging from 1 inch to 2 inches in diameter and sewer house connections from 4 inches to 6 inches in diameter, as referenced in the related Area Water and Sewer House Connection contract solicitation for approximately 11,000 linear feet of water connections and 2,600 linear feet of sewer connections across Prince George's and Montgomery Counties, Maryland.
The document establishes mandatory technical specifications and installation procedures for contractors performing water and sewer infrastructure work under WSSC projects. These corrosion control details are essential reference materials for bidders and contractors responding to the May 26, 2026 deadline for the Area Water and Sewer House Connection solicitation. The specifications address critical protective measures including bonding of metallic components, cathodic protection through sacrificial anodes, insulating flange installations to prevent galvanic corrosion, and proper test station placement and configuration. Contractors must comply with these WSSC standard details when submitting sealed responses through the agency's eProcurement Portal, ensuring that all work related to the approximately 150 new service installations meets established corrosion control standards and specifications.
