Soakaway design BRE digest 365 Soakaways have been the traditional way to dispose of stormwater from buildings and paved areas remote from a public sewer or watercourse. In recent years, soakaways have been used within urban, fully sewered areas to limit the impact on discharge of new upstream building works and to avoid costs of sewer.

For small soakaways serving 25m2 or less, a design rainfall of 10mm in 5 minutes is quoted in the Building Regulation Approved Document H as being an appropriate worst case. For soakaways serving areas greater than 25m2 reference should be made to BS EN 752-4, or BRE Digest 365 Soakaway design. BRE Digest 365 is the most commonly used document. BRE Digest 365 Back in 1991, the Building Research Establishment (BRE) published its guidance on soakaway design. The BRE acts as a centre of building science and as a consultancy on all things to do with the built environment. In other words, when they publish something, it’s worth following. The tests are carried out in accordance with the methods described in BRE Digest 365 "Soakaway Design", but modified based on the advice given in Section H2 of Building Regulation Approved Document H "Drainage and Waste Disposal" 2002. Once the trial pit is excavated a 300mm x 300mm square section is excavated by hand at test level. Published Standards do not include soakaway tests, so the UK standard for these tests should continue to be use, namely BRE Digest 365: BS EN ISO 22282-2: 2012: Part 2: Water permeability test in borehole without packer: BS 5930 clauses 25.4, 25.5, 27 and 28 deleted. Accommodated in BS5930:2015: BS EN ISO 22282-3: 2012: Part 3: Water pressure.

The regulators are increasingly asking for it at planning and pre-construction stage. To aid in the design of the soakaway, Ground Investigation Specialists Ltd can carry out in-situ testing to determine the soil infiltration rates of the near surface strata, all in accordance with BRE Digest 365. To avoid this risk many design standards including BRE Digest 365 specify that the soakaway must be able to empty half its storage volume within 24 hours. This also prevents unsanitary or anaerobic conditions from forming within a soakaway which has a pool stagnant water at the bottom for long periods following rainfall. BRE.
