Case Study - CCTV Drain Survey for Wheatley Homes, Henlow

CCTV Drain Survey for Wheatley Homes, Henlow

The Drainflow team recently paid a visit to the attractive village of Henlow between Biggleswade and Hitchin. Our client, Wheatley Homes, asked us to carry out drain jetting and a CCTV drain survey in the new Victoria Cross housing development in preparation for local water authority adoption of the foul and storm drainage system.


Storm Drainage

This is also known as surface water drainage. Storm drainage collects the water from roads, gutters, roofs, patios, and driveways. The water that is collected is free from household waste, and so it can run off into watercourses, and has no need to be treated in the sewers.

Foul Water Drainage

This is the waste that comes from bathrooms, kitchen, and utilities. The foul water drainage system collects it and transports it to the sewers where the water is treated. Storm and foul water drains obviously need to be kept separate in order to eliminate the risk of pollution.

Drainflow Carries Out CCTV Drain Inspection and Cleaning

The drainage system for a new housing development needs to be inspected and flushed through prior to public use. The Drainflow team checks for any sewer misconnections and inspects the pipework for potential blockages.

Drain clearance for new housing developments utilises two procedures:

  • CCTV Drain Survey. This is an inspection of the drainage system which allows us to check for blockages, or damaged pipes. We use a remote-controlled CCTV camera, mounted on a ‘crawler’ platform. The HD camera provides 360° real-time imagery to our surface monitors from the interior of the pipework.
  • Drain Jetting. Drainflow engineers use drain jetting hoses to cleanse the pipe work serving the storm and foul water drainage. Working from the mouth of the drain, water jets exceeding 3000psi flush out mud or silt, dislodge wedged objects, clear accretions clinging to the pipework.
