Important changes – Public Sewer Connection

Posted in Latest News on 01 October 2012

On October 1st 2012 important changes came into force for any building and construction work that involves connection to the public sewerage network in Welsh Water’s operating area.

The Welsh Ministers’ Standards will standardise sewer construction and mandatory adoption and will improve the long-term performance and reliability of the network. Ensuring that sewers connecting to the public network are constructed to an adoptable standard will help to avoid future problems such as sewer flooding of homes and pollution of the environment.

The requirements for construction standards will mean that all new gravity foul sewers and lateral drains that connect with the public sewerage network must be constructed to agreed specifications. They will then be adopted by Welsh Water and become their responsibility to maintain.

How could this affect you?

The Water Industry (Schemes for Adoption of Private Sewers) Regulations 2011 provide for the transfer of private sewers and lateral drains connected to the system between 1 July 2011 and 1 October 2012. This second transfer will happen on 1 April 2013.

The Welsh Ministers’ Standards have been published using powers under Section 42 of the Flood and Water Management Act 2010. It will also become a requirement for every new sewer connection and lateral drains approval by Welsh Water (foul or surface water sewerage) to be conditional on an adoption agreement before any work begins.

An adoption agreement will be needed whether you are connecting a new or existing property to the public sewer network for the first time, or if you are building a large multi-phased development. The only exception to this requirement is if a new connection to the public sewerage system is only for a drain which does not extend beyond the boundary of a premises. The new requirements mean that some customers will be required to enter into sewer adoption agreements for the first time. Others, such as large scale developers who know about the company’s long-standing arrangements, will need to revise their procedures.

Following these changes, an adoption agreement must be in place before any construction or connection to sewers and lateral drains to the public network can take place.

Welsh Water have also produced a short film explaining the changes in the law relating to Sewer Adoption and Connection in the operating area, and how this will impact you.
