For decades, urban drainage was guided by a simple philosophy: get the water off the streets and into the nearest river as fast as possible. However, as impervious surfaces expanded and extreme weather events became more frequent, this approach led to overwhelmed systems, urban flooding, and severe ecological damage to receiving waters.

The standard provides a clear, rule-based approach to dimensioning municipal wastewater treatment plants that use a single-stage activated sludge process. This method covers everything from calculating baseline carbon removal to designing complex systems for nitrification and denitrification. The primary objective is to balance the active biomass in the aeration tank with the separation capacity of the secondary settling tank. used in wastewater treatment
