Driving down pumping costs
27 February 2015
Welsh Water is set to reduce the cost of its roadside pumping kiosks, following the adoption of ABB variable-speed drives. Up to 20 kiosks a year are to be installed. Each contains two pumps, each driven by an ABB drive for water and wastewater, ACQ810, up to 22kW, in duty/ standby mode, housed in IP54 enclosures.

The water utility needed to pump water to, and sewage away from, roads on new housing estates that are adopted by the local authority.
Welsh Water wanted a standard solution that would be simpler than the previous method. It specified its requirements to ABB, with which it has a framework agreement covering the supply of variable-speed drives. ABB worked on the project with its Authorised Value Providers, APDS.
The kiosks come with a generator changeover panel. The generator is external and brought to site in the event of an emergency. The changeover panel has a specific type of connector fitted, allowing the generator to be connected very quickly.
One of the major requirements specified by Welsh Water is to have its own pressure and flow parameters incorporated in the drive software. This allows its engineers to easily adjust the kiosks’ pumping regime to meet the needs of housing developments as they expand.
Another example of these customised parameters is the emergency stop feature. In the event of one drive stopping in an emergency, the other drive would come online which could cause a problem for Welsh Water, particularly in the event of a pipe burst. An interlock was needed on this parameter, preventing the second drive from kicking in so that a leak could be traced and corrected.
The ABB drives offer customised control panel displays with the error messages familiar to the company’s engineers. The drives provide data over their Modbus link to the company’s telemetry system. As Welsh Water is using telemetry across the board, it was important that any drives installed could integrate into this system.
