The adoptable station was a 3m internal diameter by 6.35m deep concrete chamber with a separate, adjacent valve chamber. The pumping station requires an emergency storage of 39.2m3 to cater for the occupancy of the 245 dwellings. The water pumping station had all the requirements demanded by United Utilities including control equipment housed in a road side weatherproof kiosk. The sewage pump station was supplied with two DGN pumps, one ultrasonic level detection system and one ATEX FLO101 high level alarm float switch. T-T also installed a Text-Tel telemetry unit to monitor any alarms prior to adoption.
Due to a low point along the rising main a washout chamber and air release valve was required. The washout chamber is designed to ensure any sediment that may settle in the lowest point of the raising main can be washed out via a manhole access. The air release valve ensures that there is no air entrapment in the pipelines, thus avoiding water hammer.
The Estimating Manager from Bovis Homes comments “I have used T-T Pumps for over 25 years and I have always received good, professional advice. In one instance a S104 station which was particularly difficult to achieve technical approval with United Utilities, T-T’s Technical Manager attended a meeting with me and his knowledge proved invaluable in finally securing approval. T-T provide a prompt detailed design to enable submission for approval . During installation the T-T team attended pre-start meeting and were always willing to help and assist in the civils and mechanical and electrical installation. They are very accommodating in adjusting dates to meet our site deadlines. T-T give good knowledgeable advice from sales through to delivery and are always willing to help.”
The delivery and installation schedule of the sewage pumping station was arranged to suit the requirements of the overall site program and the adoptable pumping station was commissioned to ensure full working order. T-T lead the adoption process and ensured a smooth handover to United Utilities.
