    Common challenge

    The common challenge tackled by DOC2C's is the existing low-technology infrastructure for drinking water production, soon inadequate to ensure supply of excellent water quality while adapting to pollution and climate change.

    Production of safe drinking water is increasingly under pressure in the area. The main concern is the growing concentration of Dissolved Organic Carbon (DOC) in surface water. DOC reduces the efficiency of all treatment steps and threatens water quality due to emerging substances, formation of harmful disinfection by-products and lowered biostability in the network.

    Main Achievements

    DOC2C’s raised the knowledge level about innovative technologies for DOC removal/control, and has served as the basis for the evaluation of these technologies by others. All technologies come with pros/ cons, but having a team of utilities and researchers involved in technology development and validation, gives confidence to the water industry in their decision making about the technologies. Working in collaboration we have implemented many novel technological approaches to water treatment and monitoring associated with DOC removal. We published several peer reviewed papers and a wide range of more trade related periodicals. Alongside the very well attended annual workshops, we presented widely at nation and international conferences and more locally to key stakeholders including the local community. This has all supported the more rapid transition from low to high technology in the water sector and expanded the range of technical solutions that are suitable to produce drinking water from fresh surface water. Examples would be new piloting at Scotland, Anglian Water, and now also in Birminham UK, along with potential future studies of new technology in Singapore, Australia, and the USA. The expansion of infrastructure was evidenced by the starting up of the Mayflower WTW, as well as the inline coagulation for PWN - both surface waters. The next project will be in Scotland. 

    The range of testingprovided the evidence and confidence required to make the transition from research to implementation (e.g., Mayflower WTW, widespread roll out Zetasizer, S::CAN instrumentation etc.) and sharing these insights via DOC2C’s means other utilities and academia can build on this knowledge and decide how best apply it to their own situations when the opportunities arise. We know of many other organizations in the UK who are applying DOC2C’s learning in their operations. Every water supply situation is unique but it is likely that others will benefit from DOC2C’s to provide future proof, cost efficient and environmentally friendly approaches to meet their drinking water supply goals. The DOC2C's project also helps with the abatement of investment and operational costs for production faciltites and R&D. This was accomplished by the body of work done and reported on by PPs; thus others can rely on that data and investigate the next stages of development/improvement/applicability rather than invest at the early stages of development.
