Sewage treatment plants for multiple properties.
Theses are calculated as follows
For each property the first two bedrooms are classed as 2 people in each then all the following bedrooms are just one person
5 bedroom house = 7 people
When calculating multiple properties the sizing should be calculated individually for each property then added together
5 bed property = 7 people
7 bed property = 9 people
Total = 16 people
Also a reduction can be made for flow fluctuations
If the total population is between 13-25 a 10% reduction can be made
If the total population is between 26-50 a 20% reduction can be made
Calculations should always be rounded up not down.
Please call us if you would like us to calculate this for you.
