Flows and Loads is the Sizing Criteria, Treatment Capacity for Small Package Sewage Treatment Plants. This code of practice was prepared by the British Water Package Sewage Treatment Plant Focus Group comprising manufacturers, suppliers and service companies of all types of small wastewater treatment systems.
This code of practice provides a table of loadings which allows the total daily sewage load from properties to be calculated and it is recommended that all designers should use this table when sizing and designing non-mains sewage treatment systems. The flows and loads values given represent current best knowledge within the UK but may change with time in line with per capita water use.
The Diamond wastewater (sewage) treatment range is designed using the British Water code of practice flows and loads, to ensure the tank is sized correctly.
