Office tank sizing
The below table gives an indication of tank sizing for a typical office. The table
is based on the average office water consumption of 50 litres per person, per day,
which is equal to 31 litres of non-potable demand. The below table can be used to
give an approximate tank sizing based on the building occupancy and its associated
demand. The information below is a guide only and Polypipe WMS recommends a full
assessment must be carried out for individual sites. Please visit www.polypipewms.co.uk
to download an assessment form.
