National Drainage Survey of 80 Factories

A large national company approached Free Flow to provide drainage expertise. Free Flow were appointed against all the major national drainage companies on both quality and value criteria.


The survey included a complete investigation of all drainage assets at all of their factory sites. The exact scope was developed with the client and a bespoke concise survey reporting format was evolved.


Over a period of six months, all 80 factory sites were visited and a thorough survey carried out which included the capture of technical information on each manhole, inspection chamber, gully, petrol interceptor and pipeline.
All foul, surface water, process and land drainage systems were inspected and all drainage assets were assessed on fitness for purpose and condition. All potential environmental liabilities were also highlighted.


Detailed recommendations were prepared for:


  • Immediate remedial works and repairs
  • Intermediate works
  • Long term improvements to meet environmental legislation and planned maintenance.

A detailed plan was prepared and all chamber covers were sprayed with either blue or red colour to indicate function.


The survey reports also detailed a breakdown of future capital and operational investment.


The project was completed on time and to budget.
