Manhole and Sewer Survey, Eccles Sewage Works
United Utilities needed to investigate the performance of overflows in and around Eccles Sewage Treatment Works.
RPS was asked to carry out a comprehensive survey that included manhole, CCTV and confined space man entry sewer surveys. The man entry survey was carried out in a large diameter brick sewer in a critical location. CCTV surveys by others had failed to give the detail required on this critical asset and the client required a visual and photographic inspection. The inspection, called a traverse, required a detailed safety assessment and plan. It was successfully completed with a 5 man specialist team and the client was able to use the records and photographic evidence as the benchmark for assessing any future deterioration.
