A corporation stop is primarily used for which purpose?

A corporation stop is primarily designed for service line connections, which means it facilitates the connection of a water service line to the main water supply line. The purpose of a corporation stop is to allow for the precise control of water flow from the mainline into the service line that leads to individual customers.

When a service connection is made, the corporation stop enables operators to turn the water supply on or off as necessary. This is essential during maintenance or emergency situations, as it allows for quick response without disrupting the entire main line system. Essentially, the corporation stop is pivotal in ensuring that individual properties can be serviced from the main water distribution system while maintaining operational control over water flow.

In contrast, options related to valve control and drainage systems do not align with the specific function of a corporation stop, which is specifically tied to service line connections.
