Commission to investigate Thames Tunnel

 An independent commission is to study the case for the massive Thames Tunnel. The tunnel is Thames Water’s preferred solution to reduce sewer discharges into the Thames and avoid EU fines. But it is hitting increasing opposition from local residents, councils and MPs.

The commission will be led by Lord Selbourne. He said: ”The key question is whether this multi – billion pound scheme is the best solution for making the Thames cleaner or whether there are sensible alternatives that are cheaper, greener and less disruptive”. Thames Water’s Chief Executive, Martin Baggs, recently revealed that the sewer’s initial £3.6 billion price tag  - initially costing customers £65 per year for life – was based on 2008 figures and ‘will inevitably increase’. 

The concern has to be that the Water Companies have a strong incentive to favour capital intensive rather than operating cost schemes. One of the reasons for this is that any new capital expenditure increases the Regulated Capital Value of the business and therefore increases returns to shareholders. This is one of the main reasons why investors like Mcquarie bank are able to achieve returns of nearly 12% for their shareholders. Ofwat is looking at the capital cost, operating cost balance and in the view of this blog needs to take action to redress the balance. 

Ofwat review backs slimmer regulation

Defra has published David Gray’s review of Ofwat. The main conclusion is that the regulatory review process has worked well and that there is no need for major change. It does suggest that a lighter, less prescriptive approach is needed back by much clearer guidance from Government on the objectives.

The review has recognised the highly negative impact on the industry of the current 5 year roller coaster of investment and all the unnecessary costs this imposes on the supply chain.  The reviews recommendation to reduce the burden of reporting is to be welcomed.   

The concern is that the current regulatory process encourages capital intensive, end of pipe solutions and does not adequately address the need for the industry to become more sustainable and adapt to the challenges of climate change and population growth. Gray does recognize that currently there is an incentive for water companies to increase their regulatory capital valve and hence return to shareholders and suggests that there needs to be a review by Ofwat of the current rewards and penalties and framework of incentives. There is increasing concern in the industry that some current shareholders are only there for the short term gains – as evidenced by the bid for Northumbrian Water and that some water companies are selling key assets like buildings and then leasing them back – the model that ultimately led to the downfall of Southern Cross.

The industry has some massive challenges – especially the unprecedented growth in population and the uncertainty of climate change. Innovation and sustainable solutions like reuse of water and management of catchments must become the norm – it is disappointing that Gray has not taken this on board. Lets hope that Richard Benyon in the forthcoming water white paper rises to the challenge.    

Private sewer transfer goes ahead

Changes being introduced today (1^st July) by Defra mean that from October responsibility for private sewers will transfer to the water companies. This change has been a long time happening and will remove the uncertainty and risk from householders. For water companies it means a doubling in the length of sewers for which they are responsible and also a massive increase in workload.

The change may have unexpected consequences for the water companies. The condition and repair history of the sewers being transferred is not known. Currently repair work has been done on a short term fix basis with no incentive to solve the underlying long term issues. This is where the real benefit to society lies. Hopefully wasteful repeat visits to repair reoccurring blockages will become a thing of the past. Finding and justifying long term solutions wont be easy given the complete lack of knowledge of the private sewer system and the lack of historic records. There may be significant opportunity for the water companies to reduce repair costs but until a repair history is established this may be hard to justify.

There will certainly be a huge increase the number of calls with customers. Managing this well will be crucial if water companies are not to see their Service Incentive ratings plummet. As yet no one knows what the cost of all this will be. it is likely that some water companies will push for an interim determination and that may bring fresh problems.
