Water Service Installation - Fiskdale, MA

A typical municipal water system consists of transmission mains, distribution mains, and service lines. Transmission mains are designed to convey large amounts of water over great distances, typically between major facilities within the system including but not limited to treatment plants and storage tanks. Distribution mains are an intermediate step toward delivering water to the end customers and are smaller in diameter than transmission mains and typically follow the general topology and alignment of the city streets. Fire hydrants, isolation valves, control valves, blow-off valves and other operational and maintenance appurtenances are often connected directly to the distribution mains. Service lines, also called services, transmit water from the distribution mains to the end customers.

A typical residential water service consists of a corporation stop, curb stop, curb box, and 1” PE3408 polyethylene or type K copper tubing. Each of these components are described in more detail below:

• Corporation Stop: A corporation stop is the primary control fitting and its sole purpose is to allow for the installation of a new water service line without interrupting water pressure within the distribution main. It is designed to be installed under pressure with a drilling and tapping machine and is either threaded directing into the distribution main or threaded into a service saddle that is strapped to the distribution main. Once the corporation stop is installed, it is ready to accept the polyethylene or copper tubing which connect to the curb stop.
• Curb Stop: A curb stop is an inline valve that works on the same principle as a corporation stop. It is typically the first (and only) valve installed downstream from the corporation stop and the only valve designed specifically to control the flow of water to the facility. While corporation stops are typically buried with no access from ground level, curb stops are installed with a curb box
• Curb Box: A curb box is the “above ground” access point to the curb stop. Curb boxes are typically made of cast iron and adjustable in height to allow for grade adjustments.
• Polyethylene and Copper Tubing: Depending on the municipality, polyethylene or copper tubing may be used to connect the corporation stop to the curb stop, and the curb stop to your building. Services larger than 2” are most often constructed using ductile iron pipe.
