Private Drainage Surveys

Return to services list

We undertake private drainage surveys to determine the connectivity, pipe size, cover levels & invert levels of non public sewers.

These surveys consist of:

• Identifying private manhole covers
• Determining its function i.e. foul, surface or combined
• Obtaining outgoing pipe sizes & depths
• GPS to obtain cover levels & locations of each manhole cover
• Dye testing, CCTV or electro location to determine the private sewers connectivity

The information obtained is then processed and the two documents are produced.

One document to illustrate the private sewer network and the other, a schedule, to provide the information on each private manhole surveyed.
