Clean Water Modelling Advisory Group Autumn Conference

Transcription

1 Clean Water Modelling Advisory Group Autumn Conference Day 1: Modelling the Demand for Water Thursday 23 October 2014

2 Facing water industry challenges Hans Jensen

3 Topics for today What is UKWIR? What do we do? A non-competent view on modelling water networks, distribution and delivery!

4 UK Water Industry Research Ltd? GWRC 2011

5 What UKWIR is about. Procuring and delivering single voice research on behalf of the water industry Robust and reliable evidence based on sound science Collaboration Shaping and leading the future research agenda Sharing best practice guidance and encouraging continuous improvement

6 Challenges

7 Water Act priorities Service and price Outputs are delivered at least cost in a sustainable way A long-term perspective Better reflecting water scarcity and environmental damage Catchment management approaches Encouraging water trading Conserving water resources Affordability Competition for business customers and water trading

8 Examples: UKWIR water mains and related research DOMS 15 years on and guidance manuals Tools for the DOMS forward looking approach Integrated network management roadmap Effect of pressure on meter accuracy Smart sensors Mapping the underworld Leakage

9 Customer behaviour and water use (with EA) Understanding changing consumption patterns due to improved efficiency, economic pricing and social pressures, weather and regional dimensions Better methodologies for demand forecasting including behavioural change and mapping consumption behaviour Structured approach to data collection and linkage to existing geo-demographic segmentations A tiered approach according to data availability to improve forecasting & analysis for WRMPs, PR14

10 Smart metering in the water sector (with Ofwat & EA) Project need was identified by the industry s Smart Metering Advisory Group Understanding customer expectations and perceived benefits by a review of metering trials and targeted customer interviews Learn from and compare with the energy sector trials In-depth understanding of costs/benefits/value across stakeholders and developing a robust cost/benefit model Shared framework to collect, aggregate and categorise information

11 Current leakage projects... Methods to quantify leakage Assessment of Low Flow Components of Night Use and the Water Balance Effect of Weather on Leakage and Burst Factors affecting background leakage Improved Household Night Use Allowances Leak Detection on Plastic Pipes Quantification of Customer Supply Pipe Leakage

12 A non-competent persons view of modelling water networks, distribution and delivery It needs doing! The right kind of people are doing it! Sharing best practice guidance Research needs? Technology needs?

13 What are we looking to achieve? A sustainable service that is an exact fit with agreed customer requirements delivering WATER DISTRIBUTION: VISION FOR 2050 levels of service at optimum cost through a fully-controlled intelligent distribution system

14 Some specifics: Good quality sensors and data Diurnal variations and peak instantaneous or fifteen minute demands Daily demand profile changes and trends Pipe condition Demographics Climate change

15 Some more specifics New pipe materials with intelligence Realistic pipe material condition assessment and remaining life determination methodologies Realistic whole life costing methodologies including carbon and social costs Algorithms for real time network management Understanding what to respond to what does the data actually mean Turn data into information that can be used How much data do we actually need centrally, if at all?
