Anglian Water is generally supportive of Policy DM4 particularly the reference to Sustainable Drainage Systems (SuDS) and incorporation of water efficiency measures as part of new development. forming part of the design of new development.

However we would ask that the policy be amended to include a positive reference to the provision of SuDS by making it clear that it is the preferred method of surface water disposal and specific reference to the risk of sewer flooding as outlined in our response to the previous Local Plan consultation.

In respect of water efficiency/re-use we are actively supporting residential developers to include such as part of our Green Water Programme (https://www.anglianwater.co.uk/developers/green-water.aspx). Such measures are not limited to rainwater harvesting and can also include stormwater recycling systems and water recycling systems.

We would therefore suggest that list of measures referred to in the Policy should be extended to include these measures as well as rainwater harvesting.

It is therefore proposed that Policy DM4 is amended as follows:

'a. it does not increase the overall risk of all forms of flooding in the area or elsewhere through the layout and form of the development and appropriate application of Sustainable Drainage Systems (SuDS;
b. That no surface water connections are made to the foul system and connections to the combined or surface water system is only made in exceptional circumstances where it can be demonstrated that there are no feasible alternatives (this applies to new developments and redevelopments);
c. that adequate sewage treatment capacity and foul drainage already exists or can be provided in time to serve the development;
d. it will be adequately protected from flooding in accordance with adopted standards wherever practicable;
e. it is and will remain safe for people for the lifetime of the development; and
f. it includes water efficiency measures such as water re-use, stormwater or rainwater harvesting, or use of local land drainage water where practicable.'
