Case Study – CCTV Drain Survey for Sisk at Wembley

CCTV Drain Survey for Sisk at Wembley

No sooner had the Drainflow team taken delivery of our new van, but it was out on the road heading for its first job in Wembley. John Sisk & Son recently won the contract for two new residential buildings – NE02 and NE03 – at Wembley Park’s North East Lands. Drainflow was called in to carry out a CCTV drain survey and drain jetting operation.


CCTV Drain Survey

It’s quite something to carry out a CCTV drain survey with the iconic Wembley arch towering over you! The new van was all ready to go with our CCTV crawler; this is a remote-controlled, wheel-mounted CCTV camera that goes deep into the drainage system and sends back real-time 360° images to our surface monitor. Drainflow engineers can inspect the pipes for damage and blockages; better still, they can pinpoint any problems.

Drainflow Drain Jetting

Cleaning out a drainage pipes requires drain jetting. Tough, flexible hoses allow us to work from the mouth of the drain, sending high-pressure water jets in excess of 3000psi right through the system. Whether the problem is debris from the site, or encrusted materials on the pipes, the sheer force of the blast is guaranteed to dislodge it.

Drainflow Drain Jetting

The Sisk construction job required a survey and drain clearance of both storm and foul water drains:

  • Storm Drains. This is surface water collected from gutters, roofs, pavements, and roads. The water doesn’t contain any household waste so it can run off into watercourses, rather than being treated in a sewage works.
  • Foul Drains. This is water containing waste that comes from bathrooms, kitchens, etc. The foul drain transports waste water to sewage works where the water is treated.
