Case Study – Storm water culvert CCTV survey

UKDN Waterflow Culvert Survey

Project: Culvert CCTV survey

Customer: Cheshire East Borough Council

Sector: Local Authority

Location: Kidsgrove, Staffordshire

The challengeUKDN Waterflow Culvert Survey

UKDN Waterflow undertook surveys of five storm water culverts in and around the Kidsgrove area on the Staffordshire border, providing detailed reporting to engineers on behalf of Cheshire East Borough Council.

Investigations were carried out over several days with a three man technical services team handling the large bore 900mm culverts, and a mobile CCTV crew from Stockport using the latest Ipek mainline CCTV crawler unit to provide the very best high resolution footage.

Access to the culverts was through triangular ‘Hartlid’ covers leading to brick manholes and catchpits. Confined Spaces access, dye testing and sonar tracing were all used to determine depth flow and direction of the culverts.

The culverts, including one measuring 1.2 kilometres, totalled over three kilometres in length and were of concrete, brick and twinwall plastic construction.

The solution

Detailed reports were issued for each of the storm water culverts including levelling surveys and topographical information to assist the client in accurately modelling the area. This is critical when calculating flow capacity, and allows us to create an accurate and detailed programme of immediate repairs and preventative improvement.
