About this file
This is a standard details document for corrosion control specifications prepared by the Washington Suburban Sanitary Commission (WSSC Water) in Maryland, serving as technical guidance for water infrastructure projects. The document provides a comprehensive table of contents listing 59 detailed specifications organized into seven sections covering ductile iron pipe bonding, thermite welding, sacrificial anode installation, insulated flange joints, test station installations, field-applied coatings, and polyvinyl chloride (PVC) AWWA C-900 pipe anode protection. These specifications address corrosion prevention and cathodic protection methods for water main connections, valve installations, hydrant bonding, pipeline crossings, insulating joints, and house connections ranging from 3 inches through 12 inches in diameter. The document was last updated in September 2021, with certain sections revised as recently as August 2020.
The specifications contained within this document serve as the technical standards and design details that contractors must follow when executing water and wastewater infrastructure repair, rehabilitation, and replacement projects under WSSC Water's Indefinite Delivery/Indefinite Quantity requirements contract. These corrosion control details are essential components of the construction standards applicable to work involving water mains, valves, valve vaults, water and sewer house connections, meter housings, manholes, fire hydrants, and other appurtenances throughout Prince George's and Montgomery Counties, Maryland. Contractors responding to WSSC Water solicitations for urgent repairs and rehabilitation of water and wastewater assets must ensure compliance with these standardized corrosion protection details as part of their overall project execution and quality assurance procedures.
