The Consortium were presented with the Award for its work on Boughton Water Treatment Works. As part of that work the potential existed to make the filter building more sustainable by harvesting rainwater from the building roof and using this within the process to supplement the output of drinking water. The rainwater harvesting system has been designed to be sustainable by working under gravity requiring no energy input to get the harvested water into the wash water tanks. In addition by re-designing the collection point locations and routes no additional materials were required to harvest the rainwater.
The treated water pumps on site have different capacities and are chosen to operate depending upon the required flows and pressures within the water distribution system. This allows the pumps to operate more efficiently and hence save on the use of power.
In designing this scheme environmental issues were a very important consideration and it is thanks to the client, Dee Valley Water, for being open to the suggestions put forward by the consortium.
