Water supply engineering

Sourcing, treating and distributing drinking water.

In depth

Water supply provides safe, adequate water from surface or groundwater sources via intake, treatment, storage, and distribution. Planning considers demand growth, yield, reliability and cost. Dams and reservoirs regulate supply; groundwater needs sustainable abstraction.

Key points

  • Source selection
  • Per capita demand
  • Reservoir yield
Example

A city draws water from a river reservoir 30 km away.

Why it matters

Water supply systems deliver safe drinking water to communities, so their design protects public health and supports growth.

Where this is used

  • Planning a new water source and treatment plant for a growing town.
  • Designing a supply main to serve a new housing estate.
  • Checking the quality of raw water before treatment.

Frequently asked questions

What is Water supply engineering?

Sourcing, treating and distributing drinking water.

Why is it important to understand water supply engineering?

Water supply systems deliver safe drinking water to communities, so their design protects public health and supports growth.

What are the main stages of a water supply?

Abstraction from a source, treatment to a drinking standard, storage, and distribution to consumers under sufficient pressure.

What affects the choice of source?

Quantity, quality, reliability, cost and the environmental effect of abstraction.

How is Water supply engineering used in practice?

Typical applications include planning a new water source and treatment plant for a growing town, designing a supply main to serve a new housing estate and checking the quality of raw water before treatment.

What should I learn before Water supply engineering?

Study "Culverts and drainage" first (topic 77 of 112 in Civil & Structural). It covers the groundwork this topic builds on.

What are the key points of Water supply engineering?

Source selection. Per capita demand. Reservoir yield.

Can you give an example of Water supply engineering?

A city draws water from a river reservoir 30 km away.

What comes after Water supply engineering?

The next topic is "Water treatment processes", which builds directly on this one.

How difficult is Water supply engineering?
