Camera deployed to monitor pumps

Specialised ATEX upgraded cameras have been used to help monitor pumps and improve health and safety in a stormwater chamber in Bristol
Screens at Wessex Water’s Ashton Avenue works
Wessex Water has deployed a specialist camera to help monitor the commissioning and operation at one of its largest sewage pumping stations. In March 2010, the company began building a new pumping station at Ashton Avenue near the Cumberland basin in Bristol.
The facility is used for storm pumping in the event of heavy rains and includes a new 400m2 screening chamber that removes debris from the flow. The screens can handle some 8,000l/s of stormwater, however, the screening chamber sits in an enclosed water screening building, which David Mining, Wessex’s ICA technical & development manager, describes as an extremely “unpleasant environment”.
To enhance health and safety and keep staff out of the chamber as much as possible, Wessex Water has worked with German software company Mobotix and its Hampshire-based partner, security camera specialist SeSys. SeSys has deployed a Mobotix camera, modified to meet ATEX standards for explosive atmospheres, to monitor the pumps.
During the commissioning stage, the camera allowed technicians to adjust the speed of the pumps remotely. “We had experience working with SeSys and IP cameras from other projects and it was felt that the technology would be useful especially during the commissioning phase,” explains Mining.
“When the pumps are going full speed, the chamber can be an unpleasant place to work and the Mobotix cameras allow us to monitor the process from the control room.”
The SeSys SE-ATEX-IP-S-D24 camera uses technology based on a Mobotix D24 camera and was selected based on its ATEX rating, proven reliability in similar hostile locations and high quality images. “We have also integrated the video feed into the local control panel and we can also remotely view any situation over our Wide Area Network,” Mining explained.
This installation has proven reliable within the pumping station and Mining believes that the use of CCTV technology in this way helps the organisation to ensure the highest levels of service delivery, especially during times of heavy rain.
