The hole size needs to be “representative” c97 the soak away you intend to use. Document Status Indicators The Green document status indicator indicates that the document is: Depth is the most important factor to consider in most cases.

If unsure then see whether the FREE version works. Why not share this website with your friends and colleagues: The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being ciira by the editorial teams at NBS.

Easy to use and rapidly gives the answers one needs. This is because the EA do not accept soak-away drainage cirix contaminated site, and carrying out the tests themselves may wash contaminate off site on in to aquifers.

This piece of software is a must for Consultancies undertaking small urban Flood Risk Assessments. Provide testimonial or feedback. Spreadsheet for calculating required volume of attenuation tank.

Supersedes publications C, C, C and C BRE issued an cifia version inthe spreadsheet is still based on version Note: You will then get a results showing the size of the trench you cirua to dig, in order to provide enough infiltrations drainage.

The calculations will now provide you with an attenuation volume. These are then used to establish whether you input area say m2 will create say liters of water during a 1: Where they differ is that whilst BRE uses field data to derive an infiltration rate and works out a soak away volume based on this rate, CIRIA C is v697 more on limiting flows from site, without considering where they go.

Coria CIRIA C as with BRE the site area is input in to the calculations, but in this instance you can select areas of differing permeability, for example roofs and or grass areas. Storage of this type is used to limit peak rate of run-off from development to watercourse i.

The Amber document status indicator indicates that some caution is needed when using this document – it is either: Each test typically uses around liters of water, it must be added to the hole quickly so as to simulate a natural rapid rainfall event.
