Rainwater drainage scheme

The rainwater drainage scheme from the roof is a drawing that demonstrates how water from the drainage pipes is directed to drainage wells or other elements of the drainage system.

To develop such a scheme, I need:

- A building plan indicating the location of the drainage pipes
- A site plan
- Topographic and geodetic survey of the site (scale 1:500 — if possible) or indication of the natural existing slope of the site
- Information about the location of existing drainage wells (if any)

This data will allow for the creation of an accurate and effective scheme that will help avoid flooding and preserve landscaping elements.
