Do you need help with your SuDS design?
We offer two standard support packages to help you in meeting planning consent conditions:
SuDS storage volume estimation
Storage volume estimation using the UKSuDS.com volume estimation tool, supported by a letter.
For those wishing to have support in using the uksuds.com storage volume estimation tool, HR Wallingford can carry out the analysis for you and provide the report with a covering explanatory letter.
These can then be used to meet the planning officer’s requirements for an estimation of the required surface water runoff attenuation storage volume for the site.
What to expect:
- Development description and assumptions relating to discharge controls and contributing areas.
- An estimated attenuation or infiltration storage volume
- A summary of the parameters used and why, and a statement of what the results mean.
Cost: £500 (+VAT)
Please note, we will first need to confirm that a standard approach is appropriate for your site and your requirements.
