A Step Change in Water Distribution for AMP6 – how are we going to make it happen?

Our customers expect a water supply that is: always on good to drink at the right pressure delivered at an affordable price. When things go wrong they expect they expect faults to be rectified with minimal impact. This is being reinforced through the new Ofwat measures – interruptions over 3 hours, serviceability and Service Incentive Mechanism (SIM) This poses some management challenges for Water Companies and in particular Severn Trent Water:

• Estimating the impact of climate change and demographics on future consumption
• Continuing to reduce leakage and maintain the lowest per capita consumption
• Achieving stable serviceability and safeguarding future generations with an aging network
• Achieving zero complaints for all aspects of water quality – pressure, discolouration etc
• Getting the right balance between resilience v optimised network v capacity to trade water
• Developing a risk based investment programme – understanding the criticality and condition of our underground assets
• Real time data – we need to know things have gone wrong before our customers tell us
• Minimise operational/energy costs

Ideally we wouldn’t start from where we are. We need a strategy to ensure that informs the development of

Items to consider:

• Raw water / treated water
• Operational use –emergency
• nly?
• Water quality
• Value of water
• Who pays? STW for the benefit
• f Anglian?

Water Trading: Realistic proposition or aspirational?

To make this a reality it will need change of mindset and national leadership to co-ordinate the Water Industry, Regulators and Politicians

Establish Network Design Authority to oversee the end to end process & remove the silo mentality

What needs to change to enable us to make the step change?

National approach We need strategic leadership to define the rules and help identify most likely scenario – lack of clarity results in short- termism and stagnation Customer and stakeholder engagement on needs Build case for investment to secure network for future generations To incentivise water trading Company approach Change of mindset

• Balance of longterm

effectiveness v efficiency

• Stop blaming Regulatory

regime on short-termism Better alignment of asset strategies and communicate to suppliers Move from reactive to proactive Invest in more R&D and make the most of what we already have Supply Chain approach Evolve from project to programme Short term contract to long term partners Competitors to collaborators Take a system approach

• New standards for build
• Development of integrated

systems

• More consideration of how

to operate and maintain for the next 100 years

Many of the solutions lie with industry leaders to make this happen
