Storage overflow above the backwater level

Storage overflow above the backwater level

In very few cases the overflow will be above the backwater level. In this situation the overflow water can be directed straight to sewer with the given grade. Here the overflow must lie at minimum 20 cm above the backwater level. The overflow must be below the inlet pipework with a larger or same diameter as the inlet pipe.
