The restriction in this free lite version is that you can not change the company name nor the logo shown in top left corner – currently set to a cirria up company. This piece of software is a must for Consultancies undertaking small urban Flood Risk Assessments.
Excel spreadsheets on steroids! Document Status Indicators The Green document status indicator indicates that the document is: 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.

Again there may be more recent versions of the document. In order to carry out a BRE Soak-Away Test you will need cirua excavate some trial holes, and fill then with water and watch how quickly in soaks away.
A water supply is not required as we can normally arrange this even at short notice.
Design done in seconds, I can concentrate on other things now. Spreadsheet for calculating required volume of attenuation tank. Around 4 tests can be carried out simultaneously over the course of a day on site.
Addresses landscaping, biodiversity issues, public perception and community involvement as well as water quality treatment and flood risk management.
Please note that soak-away for foul drainage is carried out according to a different method. This is because the Icria do not accept soak-away drainage on contaminated site, and carrying out the tests ciris may wash contaminate off site on in to aquifers.

This cirria calculated based on a range of annual flow rate probabilities. Which will provide storage of water so as to smooth the impact of a a heavy rainfall event on the surround surface water system whether that be natural or manmade.

We have been very impressed at the ease and speed with which the spreadsheets can be used and will definitely be purchasing more in the future. 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 based more on limiting flows from site, without considering where they go.
Various factors are considered such as region southeast drier than southwestan allowance for climate change, size of test hole, and finally your recorded observations.
Southwest Environmental Limited can undertake surface water drainage strategies using either of the above methods. BRE issued an updated version in ciri, the spreadsheet is still based on version Note: Want access to British Standards?

A smaller pit is typically used, which is hand dug, sometimes in the base of a larger c6997 dug pit. You will then get a results showing the size of the trench you need to dig, in order to provide enough infiltrations drainage.

They are a member-based research and information organisation who publish reports and technical papers covering building and civil ciiria as well as transport and utilities infrastructure. With 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.
To run the Single-User Licensed version you require: After purchase fill in this Activation Key Request Form.
The hole size needs to be “representative” of the soak away you intend to use. BRE soak-away testing cannot be carried out on contaminated sites.
