How many types of water distribution networks are there?
four network types
The aim of a distribution network is to supply a community with the appropriate quantity and quality of water. There are four network types: dead end, gridiron, circular and radial systems.
What are the different types of water distribution?
The following are four major types of a water distribution system,
- Dead-end or Tree Distribution system.
- Gridiron Distribution System.
- Circular or ring Distribution System.
- Radial Distribution System.
What is the most common water distribution system?
Pipe-Network Configurations A grid/looped system, which consists of connected pipe loops throughout the area to be served, is the most widely used configuration in large municipal areas. In this type of system there are several pathways that the water can follow from the source to the consumer.
Where do the UK’s fresh water supplies come from?
