This topic covers information related to roof drains that are installed during construction. Roof drains are installed on flat roof surfaces to provide a drainage location for ponding stormwater.

This topic covers information related to septic tanks that are installed, as part of a septic system during construction. Septic systems are often installed in locations where that local jurisdiction has not provided sewage pipes for removal of wastewater and matter.

Regular cleaning and maintenance of septic tanks to remove solids is necessary.

This topic covers information related to FOG or fats, oils and grease disposal systems that are installed during construction. Fats, oils and grease from residential or commercial kitchens can clog sanitary sewer lines and in turn cause wastewater backups. A plumbing device known as an interceptor is designed to be installed in-line with a sanitary waste line to collect or intercept most fats, oils and grease, prior to their entry into a sewerage system.

This topic covers information related to sanitary waste and vent piping that is installed during construction. Sanitary waste piping carries waste water and matter from a structure. Vent piping, a component of the sanitary waste system, vents sewage gases to the exterior of the structure or outdoors.

This topic covers information related to sanitary sewerage piping systems that are installed during construction. Sanitary sewerage systems carry waste water or matter away from a structure and into a larger sewerage network for collection, treatment and disposal. A structures sanitary sewerage system includes piping, drains, valves, interceptors, separators and other components.

This topic covers information related to potable water storage tanks that are installed during construction. Potable water storage tanks are containers used to store water for human consumption. The container may be roof or ground mounted, elevated or installed indoors. They are generally installed in close proximity to the structure they provide potable water too.

This topic covers information related to water pumps that are installed during construction, as part of a plumbing system. A water pump may be a direct lift, displacement, velocity, buoyancy, or gravity type. They are used to move fluids, such as water into or through a structures plumbing system.
