Uffington Waste Water Treatment Works (WwTW) is operated by Thames Water and serves a population of 700-800 in a rural situation. The WwTW comprised a Primary Settlement Tank, Filter Bed and Humus Tank. Due to its age and an increasing load from the village the works required chemical coagulant dosing to improve load removal through precipitation, settlement and filtration. The site was starting to breach consents occasionally and Thames Water was aware that discharge limits for the WwTW were likely to be tightened in the next few years. This would potentially require the need to upgrade the whole site. The cost of chemical dosing was also significant on what is a relatively small site.
