How to identify an existing drainage system

0

All fields are likely to have some form of field drainage.

Ensure you have a final drainage plan and not a proposal.  A final plan may include the words ‘ completion’ or ‘as built’ and should always be signed.

In the absence of a final drainage plan:

  • Local drainage contractors may hold copies of final record plans
  • Produce a sketch map
  • Locate any visible outfalls
  • Look for field surface signs
  • If outfall cannot be found it may be necessary to dig trenches across most likely locations

To find out more have a look at the ADDB Field Drainage Guide which looks at the principles, installation and maintenance issues.
