Pump Station Data Collection Form
The diagram below shows an example of a typical layout for a cavity drainage system using modular drain inlets.
- Calculate the Basement plan area then divide by 12 (to calculate 1 drainage point every 12m2) and show a 12m grid with one drain point within each square.
- Mark on the longest drain run from the furthest drain point to the proposed sump location, then enter this dimension into box (f) on Sheet 2.
- Include any external areas (e.g. Lightwell) providing they do not exceed a total area of 12m2, if the area is larger than this we recommend that a separate surface water pump station is used.
