Sizing and Regulations
In order to work out which Domestic Sewage Treatment Plant is suitable for your property you must abide by the British Water flows and loads guide (4). The table of loading’s on the guide, set out the suitable sizes of treatment plants for different types of property.
A domestic dwelling is fairly straightforward to work out. This is usually the number of bedrooms in the property plus two.
For example, a three bedroom house becomes five (requiring a Bio-Pure 1 Domestic Sewage Treatment Plant).
However, if the Sewage Treatment Plant is required for more than one property, then two must be added for each dwelling.
a two bedroom house plus two = four
a three bedroom house plus two = five,
and a four bedroom house plus two = six,
Add them all together = fifteen (4+5+6=15). This will require a Bio-Pure 4 Sewage Treatment System.
For a non- residential property, the size of the Bio-Pure required will depend on the purpose of the property. Please contact us and we will be able to work out the correct size Bio-Pure required for your needs.
