Project Appreciation and Objectives
The revised Bathing Water Directive (rBWD) was adopted in England and Wales in 2006 and will be implemented for the first time in 2015. The new Directive will increase the pressure on the UK government to improve bathing water compliance. Water companies play a central role in bathing water management by disinfection of effluent discharged to bathing waters, but face conflicting pressures to both control emissions and minimise expenditure. Directive compliance is predicted to drop significantly when the higher standards of the rBWD are introduced and this is expected to draw negative attention to the water industry.
This project will help companies to forward plan for the rBWD; it has a collaborative element that will set out the common issues and potential solutions, and a tailored output for each participant that sets the results in their own context with respect to the rBWD and options available to them.
Benefits to Clients
- Development of a long term and pro-active approach to ensuring compliance with the rBWD, particularly if compliance with the rBWD is lower than that with the current BWD.
- Managed risks of escalating Capex and Opex costs and avoided increases in customers' bills.
- Well informed response to the rBWD in business plans for the next AMP.
- Identify the implications of the identification of further inland freshwater bathing sites to each company.
- Identify the relevance of sewerage and coastal models for use as a prediction system for bathing water quality and how they might be used to control disinfection.
- Review the technical feasibility and benefits of using active management to operate disinfection processes at waste water treatment plants.
- Assess the current status of bathing water compliance and risks against the rBWD requirements for each participating company.
- A report that sets out:
- common issues and potential solutions being considered or implemented;
- the feasibility, benefits and barriers to the development of a real time water quality prediction system using sewerage and coastal models; and
- the technical feasibility and benefits of using active management to operate disinfection processes.
- Company-specific reports of potential impacts of the rBWD on their bathing waters and actions to deal with them.
