The UK’s Bristol Water is responsible for the water supply in the Bristol area for nearly 1.2 million people, covering a 926 square-mile region. After working in a cluttered workspace with a system developed piecemeal over the last two decades, Bristol Water decided to completely upgrade its operational control room with a new display system that helps provide improved monitoring and more efficient working conditions.

Electrosonic provided a new overview display comprised of a video wall and big-screen display; new workstation displays, furniture and consoles; and a central control rack, which includes image processing equipment. The overview display consists of six 55-inch LCDs with narrow mullions configured in a 3x2 video wall, plus a separate 65-inch LCD. The video wall is supported by a free-standing structure from Thinking Space, which eliminates the need for the room’s wall to provide structural support. The workstations, subcontracted by Electrosonic from SBFI, were designed with operator ergonomics and welfare in mind, and are tailored for two people, each of whom is outfitted with three 23-inch, edge-lit LCDs on fully-adjustable mounts.

A factory-wired central rack contains support equipment, including a video wall image processor, a KVM switch, a satellite receiver, a room controller and an audio amplifier. It also has space for eight PCs installed by Bristol Water staff, which serve as the main image sources.

Electrosonic also supplied a touchscreen controller for selecting preset video wall configurations, and remote KVM controls, which are installed on the main operators’ console, for taking full control of the video wall via access to the image processor. The video wall has a default configuration, which places the various image sources at preferred positions, but the image processor allows any source image to appear at any size anywhere on the display.

Permanently connected to the 65-inch display, an alarm monitoring system is supported by dual computers that receive data through a SCADA (Supervisory Control And Data Acquisition) system, and monitors all of Bristol Water’s pumps, water levels, flow rates and more.

A GIS (Geographical Information System) maps the precise location of all the Bristol Water assets and provides map data for the location of incidents and personnel. An SMS (Short Message Service) Board handles much of the staff communications, and logs and displays all messages as they are sent. TV news channels can also be displayed on the overview display as they often offer the quickest way of receiving meteorological, incident and relevant news.

The entire Bristol Water system is covered by security monitoring. Principal status information and related images are available on a security display in the control room; if an incident is detected, the camera nearest to the incident is automatically selected for display. For safety and practical reasons, a lone worker display pinpoints the location of each worker engaged with routine inspections or investigating minor incidents by automatically tracking the worker’s cell phone or handheld radio position.
