Types of Plumbing System

Plumbing systems are an essential part of any building’s infrastructure. They are responsible for delivering clean water for drinking, cooking, and washing, as well as removing wastewater to be treated and disposed of. There are several types of plumbing systems that are commonly used in different types of buildings. In this article, we will discuss the four main types of plumbing systems: water supply, drainage waste and vent, storm water, and gas supply.

1. Water Supply System:
Water supply systems are responsible for providing safe and clean water for various purposes in a building. They consist of pipes, fixtures, and fittings that are connected to a water source, which is usually a municipal water supply or a private well. There are two main types of water supply systems: Direct system and Indirect system.

a. Direct system:
In a direct system, the water enters the building at the main supply point and is distributed to individual fixtures and appliances. This system is commonly used in small buildings or where space is limited.

b. Indirect system:
In an indirect system, the water is fed through a storage tank or cistern before supplying to individual fixtures. This system is commonly used in larger buildings, and it helps to maintain water pressure and flow in the building.

2. Drainage Waste and Vent System:
The drainage waste and vent system is responsible for removing wastewater from a building and maintaining healthy indoor air quality. It consists of pipes, traps, and vents that are connected to fixtures and appliances such as toilets, sinks, and showers. This system also prevents harmful gases from entering the building by creating a balance of air pressure within the pipes.

a. Single stack system:
In a single stack system, all the waste from different fixtures flows into a single vertical pipe that is connected to the main sewer line.

b. Double stack system:
In a double stack system, there are two waste stacks – one for soil waste (toilets and urinals) and another for kitchen and bathroom waste. Both the stacks are connected to the main sewer line.

3. Storm Water System:
Stormwater systems are designed to handle excess rainwater and prevent flooding in and around a building. They consist of gutters, downspouts, and underground pipes that collect and direct the rainwater away from the building.

a. Combined system:
In a combined system, both the sewage waste and stormwater are collected and conveyed through a single pipe system. This is commonly used in smaller cities and older buildings.

b. Separate system:
In a separate system, the stormwater is collected and transported through a separate network of pipes to discharge into a nearby water source. This system is commonly used in larger cities and new building constructions.
