House Developments

The most common way to get a water supply is to connect a service pipe from the water main to your property. In most built-up areas, there is a main in the road or footpath to connect your property to. In more rural areas this may be further away and require a longer service pipe to be laid.

A new property must have its own supply and is most commonly connected by a standard 25mm connection onto our water main. This provides a flow rate of up to 1 litre per second and a minimum of 15 metres (1.5 bars) pressure at the boundary stop tap.

A new or replacement water supply is normally requested when:

  • New premises are being built on vacant land
  • An existing property is demolished and new property is being constructed
  • Replacement of lead, galvanised or other metallic pipes is required
  • There is an increase in water usage, which requires a larger sized water connection
  • A change to the entry of the water pipe into your site from the existing highway is desired
  • A property is on existing common supply and requires a separate supply
  • A property is divided into multiple properties
