£120.00
Maximum quantity available reached.

If you or your client are at the pre planning stage, have a planning condition or need to satisfy building control you may require a Soakaway sizing design to demonstrate the soakaway volume required. 

The output is a pdf document which provides the soakaway dimensions required.  

The calculation will be performed as per CIRIA 3D method as standard. The BRE 365 method can be used by request only.

What we require: 

  1. Address and Postcode of development 
  2. Roof Area in plan (m2)
  3. Other impermeable ground surface area which discharge to drain or to the soakaway (m2, a runoff coefficient of 0.95 will be assumed unless otherwise stated) 
  4. Infiltration rate, determined by an Infiltration test
  5. Climate change factor will be based on DEFRA's climate change allowance map assuming an epoch for development with a lifetime between 2061 and 2125.
  6. Design Storm period (if specified, otherwise 1 in 100 year summer storm assumed)
  7. Safety factor of 1.5 will be assumed unless specified otherwise. 
  8. Anticipated loading of tank/soakaway (<3T = min 0.27m cover, 12T = min 0.65m cover, 40T = min 0.85m cover, 60T = min 1.02m cover)
  9. Preferred plan dimensions/constraints (e.g. 6m x 4.2m, standard crates measure 1.2l x 0.6w x 0.42h m)

Simply post these details in the notes or email technical with your order number as the subject line.
