Drainage is the removal of surface and sub-surface water. Sustainable urban drainage systems (SUDS) are systems designed to efficiently manage the drainage of surface water in the urban environment.
Plumbing refers to any system that allows the movement of fluids, typically involving pipes, valves, plumbing fixtures, tanks and other apparatus.
Plumbing systems might be used for:
- Heating and cooling.
- Waste removal.
- Potable cold and hot water supply.
- Water recovery and treatment systems.
- Rainwater, surface and subsurface water drainage.
