    Explanation for Domestic housing sewage generation
    A treatment system for a single house with up to and including 3 bedrooms shall be designed for a minimum population (P) of 5 people.

    The size of a treatment system for a single house with more than 3 bedrooms shall be designed by adding 1 P for each additional bedroom to the minimum single house value of 5 P, eg:

    • House with 3 bedrooms = minimum 5 P systemhouse with 4 bedrooms = minimum 6 P system (5+1)

    • House with 6 bedrooms = minimum 8 P system (5+3)

    For groups of small 1 and 2 bedroom houses or flats

    • Flat with 1 bedroom = allow 3 P

    • Flat with 2 bedrooms = allow 4 P

    A treatment system serving a group of houses shall be designed by adding together the P values for each house calculated independently, eg:

    • For a group of two houses (3 and 4 bedrooms, respectively) the system shall be for a minimum of 11 P (5+6)

    If the calculated total P for a group of houses exceeds 12 P then some reduction may be made to allow for the balancing effects on daily flow of a group of houses (round UP not down)

    • Where the total is 13-25 P multiply the total by 0.9 to give an adjusted P value, e.g. if there are four four-bedroom houses the total P will be     24 P (4 x 6) and the adjusted P will be 22 P (24 x 0.9 = 21.6)

    • Where the total is 26-50 P multiply the total by 0.8 to give an adjusted P value, e.g. if there are four three-bedroom houses and three four-       bedroom houses the total P will be 38 P (4 x 5 and 3 x 6) and the adjusted P will be 31 P (38 x 0.8 = 30.4)
