UK WATER INDUSTRY RESEARCH

My UKWIR

Asset Management research theme

Asset Management

The programme area includes asset location, distribution operation and maintenance strategies (DOMS) and pipeline innovation. UKWIR developed a £10 million programme of work 'Minimising Streetworks Disruption' to improve knowledge of underground assets. Other areas of research include pipeline materials and contaminated land. Leakage projects have built around the landmark 1994 'Managing Leakage' report with UKWIR's comprehensive update in 2011. The leakage projects have been prioritised to help water companies reduce leakage to their economic levels.

Resilience – performance measures, costs and stakeholder communication

Project Status Project Completed

The Water Act 2014 gave Ofwat a new primary duty to further the resilience objective in the water industry, including highlighting the need for long-term resilience of water and wastewater systems and service provision when faced with increasing external stresses, such as environmental pressures, population growth and changes in consumer behaviour.

 

For business plans, companies will need to be able to:

  • Develop measures and targets which reflect customer priorities
  • Demonstrate that proposed costs are efficient

 

Meeting resilience requirements will also affect supply-demand planning. Updated WRMP and Drought Plan guidance moves water resources planning away from simply testing supply systems against historic droughts, with the intention of better understanding resilience to other types of drought. For example the latest Water Resources Planning Guideline states: “By testing your plan to a number of different droughts and aligning with your drought plan, you should be able to identify areas where resilience needs to be increased to meet customer and stakeholder expectations, or government policy”.

 

Improving resilience can involve choosing appropriate investments in the short-term to reduce risk for future customers, where the probabilities of risks occurring and their impacts are often uncertain difficult to predict. This makes it problematic to develop measures and targets. In addition, communicating risks in order to assess customer priorities poses difficulties.

When is ‘surface water removal’ the most cost beneficial solution?

Project Status Project Commenced

Removing surface water from foul or combined sewers offers a number of benefits, both in terms of reducing operational expenditure and flows (and subsequent flooding and spill frequency), as well as offering wider community benefits.

There is an increasing appetite across the water industry to consider and deliver such interventions to help manage a range of drivers, but this appetite is not matched by an in depth understanding of the scenarios and catchment characteristics that make surface water removal options more cost beneficial than traditional engineering solutions.
