CCTV DRAINAGE SURVEYS AND SEWER CLEANING

Our CCTV services are operated on a nationwide basis with our client base consisting of various water companies, consulting engineers, construction companies and private clients.

In the event of the sewers for CCTV investigation requiring cleaning prior to CCTV then we offer a cleansing service via use of our mobile jetting unit.

A large proportion of our CCTV work is for post construction company “hand over” on sewers for water company adoption and also private client “build over” surveys for property extensions.

Using our mobile CCTV unit containing state of the art CCTV technology we are able to check the inside of drains and sewers in order to make sure they’re in top condition, prove connectivity and trace underground pipe routes using the CCTV crawler in combination with a Sonde device to indicate a location above ground.

Our modern CCTV drain survey technology makes surveying sewers and drainage structures more efficient than ever. The wheel-mounted camera unit or “crawler” is lowered into the drainage network and the crawler travels along the pipe sending high-definition images back to a digital image recorder and monitor within the CCTV control van.

The data is viewed by our trained operator who will note any potential issues, such as cracks, fissures, collapsed sections, ground water ingress, blockages or displaced joints and code the fault data in order to produce a drainage report using our WINCAN software.

CASE STUDY

STAFFORD SEWER
CCTV SURVEY

Our client, a major drainage engineering consultancy needed to verify the path and condition of a culverted watercourse along a storm sewer in order to assess the potential capacity of the sewer to carry extra flows and determine if any remedial works were required within the sewer based upon its current condition.

The CCTV crawler was introduced to the sewer at the last D/S manhole prior to the watercourse outfall into a lake. We then CCTV’d upstream through a number of manholes on the storm run until we came across the infall point of the watercourse at the end of a ditch which required remedial work and also CCTV proved that a suspected pipe connection was not in use and the sewer capacity would not be exceeded by future extra flow input volume
