Surface Water Drainage Calculations

Many local authority together with projects requiring Code for Sustainable Homes require both flood risk assessments and surface water calculations. Both help to identify the current and potential risk of on and off site flooding and excessive surface water runoff.

Our team of engineers are able to provide you advice on how to best minimise and where required manage surface water runoff to ensure compliance with both local planning authority guidelines and SUR1 of the Code for Sustainable Homes.

Our best advice would be to get us involved early, ideally at a pre planning stage or most certainly prior to any works commencing onsite. This will enable our team to develop the most cost effective solution whilst working with your design team to achieve compliance.
