Dwr Cymru Welsh Water supplies water, sewerage and trade effluent services to homes, offices and businesses in Wales and parts of England. In Henllan west Wales they have a wastewater treatment plant which serves the village with a population of over 800. The population of the area has been projected to increase over the next 30 years and so required an upgrade as part of their growth plans.
The Overall Objective
They required a system to enable them to maintain treatment capacity during the construction of new facilities at its Henllan and Croesgoch Sewage Treatment Works in west Wales, as part of the water company’s capital investment programme for growth projects.
Siltbuster Process Solutions were contacted to provide a complete temporary treatment system to be delivered at short notice. SPS were able to fully install the system within 3 weeks to treat up to 14L/second. The system consisted of 4 HB40R units, 2 with an auto desludging facility to provide primary settlement, and 2 further units as humus settlement in conjunction with the Welsh Water internal SAF unit.
Due to the success of the SPS plant, the existing works were taken offline to allow the complete refurbishment of the sites. Ultimately this approach provided the efficiency and flexibility in the construction programme to ensure that the key delivery date was not compromised.
