A nice example of a high level inlet into the pond, supported with gabion baskets providing a stable headwall
Example of a swale with inlet connections of traditional underground drainage protected by gabion type baskets.

A nice example of a detention basin adjacent to the highway with high level weir overflow into drainage ditch
A lovely example of a swale with a gravel base, designed to infiltrate, convey and clean surface water
A combination between traditional and green roofs. Green roofs hols the rainwater for a longer period than traditonal roofs which helps to reduce the rate the water runs off the roof decreasing flood risk

Equipment required for Surface Water Testing in accordance with CIRIA 156, it isn\'t too bad if it is lovely weather like this!
Nice example of using the public open space as a way to store and mange surface water safely.

Is Code for Sustainable Homes Mandatory?

From 1 May 2008 it is now mandatory for all new homes to be rated against the Code and include a Code or nil rated certificate within the Home Information Pack. We are increasingly becoming aware that, when planning permissions are being awarded, the Local Authorities are including a condition that the house must achieve “Code 3 for Code for Sustainable Homes”.

In order to achieve compliance with the Code there are mandatory elements for surface water drainage which must be met otherwise CODE cannot be met and the application could be void.

The mandatory elements require the development to have a surface water system designed to the 1 in 100 year storm, plus an inclusion for climate change. In order to satisfy the criteria infiltration tests and soakaway sizing must be completed by a qualified individual, chartered and be a full member of a recognised Institution as ICE or CIWEM, to which Louisa satisfies this.

If the mandatory elements cannot be met then it will not be possible to obtain Code for Sustainable Homes, this means that you will not be able to discharge the planning conditions, hence, potentially making the permission invalid.

Take action and ask for some advice from us.

If you think it is likely that your site will be required to achieve Code for Sustainable Homes then we strongly recommend that you speak to us to ensure that you can achieve the mandatory elements at an early stage. Not doing so could cost you thousands of pounds in wasted application fees and architects fees.

We are currently designing a flow chart for energy assessors which will be available for download here soon.
