Case Study – CCTV Drain Survey for McLaren at Hale Wharf

Drain Jetting and CCTV in North London

Hale Wharf is a new waterside development for the London Borough of Haringey. The first phase of development was completed by McLaren in 2022, delivering 249 new homes. In phase 2, McLaren will deliver 191 further homes on the banks of the River Lee Navigation in North London.


Drainage Requirements on Construction Sites

All construction sites require drainage experts to map existing drainage systems, clear drainage issues caused by accumulated waste materials, and prepare drains for full use. At every stage of the development, McLaren needs to be able to call on drain clearance teams that have the skills, specialist equipment and experience to carry out work promptly and efficiently.

CCTV Drain Inspection and Drain Jetting for McLaren

Drainflow was contracted to carry out a CCTV drain survey on existing pipework, and flush through the system using drain jetting hoses. The Drainflow team uses CCTV technology to check for sewer misconnections and inspects the interior of pipework for potential blockages.

Drain clearance utilises two specialist procedures:

  • CCTV Drain SurveyUsing CCTV technology, the Drainflow team is able to inspect a drainage system for blockages, damaged pipes, or misconnections. The remote-controlled camera equipment, mounted on a crawler platform, is sent into the pipework. The camera sends back real-time 360° imagery, allowing our engineers to diagnose any issues, and pinpoint the location.
  • Drain JettingWe use high-pressure drain jetting hoses to flush through the pipe work. Working from the mouth of the drain, water jets exceeding 3000psi are inserted into the drains and the jets remove mud or silt, dislodge wedged objects, and clear accretions, such as dried concrete, attached to the pipework.
