The design work would be carried out to satisfy the requirements of 'Approved Document H' together with
BS EN 752, BS EN 12056-2 or 'The SUDS Manual', C753, 2015 as appropriate. We can also design drainage to be
adopted by the relevant water company
Transfer of Private Sewers
It should be noted that from 1 October 2011 the responsibility for most existing private sewers (that is a 'drain' serving two or more properties) which connect to a
public sewer was transferred to the relevant water company. It was originally proposed that all sewers subsequently constructed would be adopted by the water
companies and would need to be designed and constructed to the standards set out in 'Sewers for Adoption'. This mandatory adoption has been implementation in Wales
but is still pending in England.
The mandatory adoption of sewers means that in Wales, only drains within the curtilage of a property fall within
the remit of Building Regulations. An adoption agreement with the relevant water company has to be in place for most new sewers and lateral drains before construction
of the development can commence. Since the situation within England has not yet changed, new private sewers can still be designed and constructed to the requirements of the Building Regulations.
Implementation in Wales of Schedule 3 of F&WMA, 2010
Schedule 3 of the Flood and Water Management Act, 2010 has been implemented in Wales. This means that the surface water drainage for a new development of more than one property has to be approved
by the SUDS Approving Body (SAB) before planning permission can be granted. The surface water drainage for a small single property would still be designed in accordance with the Building Regulations.

Design of SUDS in England
In England the use of SUDS for developments of ten or more properties is applied by way of the planning system but the Building Regulations still apply for smaller developments.
