The Urban WasteWater Treatment Directive (UWWTD) is a European Union directive which has been in place Since 1991 to protect the environment from the effects of wastewater discharge. It is concerned primarily with the collection, treatment and discharge of domestic and industrial waste water (from some specific industries).
The directive has provided a number of specific targets with deadlines – In England and Wales, these targets are managed through a series of Asset Management Plans (AMP) each with a 5 year life cycle. Ofwat are the responsible body for England and Wales assessing performance and issuing guidelines for each of the AMP projects. Water companies will carry out the requirements usually via contractors. In many cases, a group of contractors are assembled as a ‘joint venture’ to manage the implementation of much of the work.
At the time of writing, AMP 6 is currently under way (2015). During the first few AMP periods, Ofwat were primarily concerned with implementation of the directive through new builds and upgrades. In the later AMPs, the emphasis has shifted to delivering value for money by maximising current assets.
The plans are outlined in the 5 yearly Ofwat price reviews and can be viewed on the Ofwat website. The currently active review is the 2014 price review. Included on this site are policies and instructions to the various Water Authorities.
In Scotland, Scottish Water are directly accountable to the Scottish Parliament, and ministers set objectives, they also tend to work on 5 year plans under the name ‘Quality and Standards’ (Q&S).
