SuDS Calculation Service

If you're at the pre planning stage, have a planning condition or need to satisfy building control you may require an Attenuation tank sizing design. This may have been completed by an Architect or a drainage engineer.

In order to complete the calculation we require:

Roof Area (m2)
Other hard (ground) surfaces area (m2)
Postcode of development
Allowable discharge rate (l/s)
Climate change factor (if specified)
Storm profile/duration (if specified)

If you are combining attenuation with rainwater harvesting the additional info is required:

No of bedrooms of proposed development
Use of rainwater - toilet flushing, toilet flushing and irrigation, toilet flushing machine washing and irrigation
