The Facts about Sewers For Adoption 7th Edition

What is it?

Sewers for Adoption 7th edition takes into consideration the new transfer of private sewers to the water authorities that took place on the 1st October 2011. In order to prevent the creation of more new private sewers and lateral drains it provides guidance on acceptable standards that will allow their adoption. Currently the publication of Sewers For Adoption 7th Edition has been delayed, however, it is anticipated to be introduced in early 2012.

What does it mean for developers?

Developers will be required to enter into a Section 104 adoption agreement for all new sewers and laterals that will connect to the public sewer system serving more than 2 dwellings.

Things to consider

Architects and planners will need to consider the implications of their planning layouts in relation to sewer adoption. As far as is practicable sewers and lateral drains serving two or more properties will need to be laid in highways or public open space. Where this is not possible sewers can be laid in rear yards/parking areas or unfenced gardens provided there is free access. If free access is not available, provision will need to be agreed with the water authority. Previously foul and surface water drainage runs tended to be routed along the rear of properties, however this will no longer be acceptable. This will inevitably result in the requirement for more space to the front of properties. Commonly agreed construction standards are to be introduced for these new elements of drainage which will be more in line with Building Control requirements rather than the standard required for the main systems within the road. These include the acceptability of plastic drainage and reduced access inspection chambers.

Will the Act benefit us?

The main benefit is to the home owner/social landlord in that maintenance of virtually all drainage will become the responsibility of the water authority.

Are there associated costs?

It will be necessary for all new private drainage to be offered for adoption under a Section 104 Agreement with the water authority. This will require that drainage is technically vetted and inspected and that appropriate bonds placed to cover the initial maintenance period. The exact costs are not known at this stage, but it is anticipated capital costs will increase to cover the administration. Need more information?
