New or replacement water supplies

A replacement water connection is the provision of a new water service pipe to a property that is already being supplied with water from Anglian Water, either by a direct supply or part of a common supply shared with other properties.

A replacement water supply is normally requested when:

There is a need to replace old lead, galvanised and other metallic pipes.
There is an increase in water usage, which requires a larger sized water connection. Existing water service pipe is relocated.
Existing property demolished and new property or properties are being constructed.
Property is on existing common supply and requires a separate supply.
Property is divided into multiple properties.

Water regulations information

It is imperative when requesting new water mains and water connections that ALL drawings and information requested in Section 5 of the 'Application for new water supplies (mains and connections)' are submitted to us with the application form. Failure to do so will delay your application being processed.

Trickle flow plugs

Important Note – All new boundary box, manifold and wall box connections will be installed with a trickle flow plug at the time of connection. The trickle flow plug will give adequate flow and pressure for the testing of the internal plumbing system, but will not be adequate to supply an occupied property.

The water meter will be installed at the same time as the internal water regulations inspection takes place to ensure compliance with the Water Supply (Water Fittings) Regulations 1999. Therefore it is important that the property is fully plumbed when requesting the meter installation.

When you are ready for the internal water regulations inspection and meter installation, please contact us on 0800 137631 9am to 5pm Monday to Friday, quoting the Anglian Water job numbers. Please allow five working days for the meter to be installed from the date requested.

At the time of the meter fit Anglian Water will also record an accurate meter location as well as confirming the postal address, occupancy date and occupier if known, which will ensure accurate billing of our new customers.

It is a criminal offence for Developers or their contractors to tamper with the trickle flow plug in any way

Chlorination information

If the service pipe you are installing falls into the following categories, you will need to arrange for this to be chlorinated and tested before we connect it to our network:

Pipes are equal to or greater than 25 millimetres internal diameter (32 millimetres outside diameter) and equal to or less than 50 millimetres internal diameter (63 millimetres outside diameter) and are greater than 100 metres in length.
Any pipe greater than 50 millimetres internal diameter (63 millimetres outside diameter) and any length.

Please liaise with our Connections Team on 0845 60 66 087 so that the connection can be booked within the chlorination validity period.
