Sewerage - PE
The PE is an estimate of the usage made of sewage facilities. It is not a measure of population. For residential areas the population equivalent is calculated as five per dwelling and is a direct measurement of the population in an area.
However for commercial areas it is calculated from the floor area, which is considered to be proportional to the number of people using a premises during the day. In this case it does not reflect the population living in an area.
