Water supply & drainage type

Question

Accepted Answer

Water supply can be either direct or indirect, while drainage can be either single stack or separate system.

Water supply can be direct, where water is supplied directly from the mains to the fixtures, or indirect, where water is stored in a tank and then supplied to the fixtures.
Drainage can be a single stack system, where all waste water is collected in a single stack and then discharged into the sewer, or a separate system, where foul water and surface water are collected separately and discharged into different sewers.
The type of water supply and drainage system used depends on the building's design, location, and local regulations.
For example, in high-rise buildings, an indirect water supply system is often used to maintain water pressure, while a separate drainage system is used to prevent foul water from contaminating surface water.
