Water Industry (Financial Assistance) Bill

John Bercow Excerpts

Wednesday 29th February 2012 Commons Chamber

[Dan Rogerson]

The hon. Gentleman is making a powerful case for the need to be mindful at all times of how outdated sewerage systems can cause problems. People may be more accepting of occasional discharges during periods of very high rainfall, but he knows north Cornwall well, and if he considers the area of Trevone he may wish to look again at South West Water’s record on delivering its promises, because in that area discharges have been occurring several times a month, and the company has yet to take action. I have raised that issue with South West Water, and we hope to address it soon, but he is absolutely right that there is a problem not just here in London, but throughout the country.

[Mr Speaker]

Order. There is a worrying pattern developing whereby the erudition of interventions is equalled only by their length.

[Mr Offord]

I take it from that only that you would like me to talk for even longer, Mr Speaker.

I absolutely agree with the hon. Gentleman, however, and having had some experience as a lifeguard in Cornwall I have seen at first hand the problems that South West Water has caused. I intend to go on to address the points that he raises.

From my experience in Cornwall and elsewhere, I am aware also that there are 500 regulated sewer overflows on Britain’s beaches that, as the hon. Gentleman rightly says, are supposed to operate only after heavy rain. However, swimmers and surfers often complain, even to me, that the overflows operate more regularly to relieve pressure on sewerage systems that are said to be “at bursting point” by the various water companies.

Despite a £10 billion investment programme by water companies since privatisation, about one in four beaches still fails to qualify for the European Union’s top category. The investment has ensured that 96% now meet the lower mandatory standard, but this still means that a swimmer, surfer or scuba diver has a 14% chance of contracting a bacterial or viral infection, and that is simply not acceptable.

Every year the water companies factor into their operating costs the insignificant fines, ranging from a couple of thousand pounds to tens of thousands of pounds, that can be levied on them, and they know that it is cheaper to pay them than to ensure that their infrastructure performs within the terms of their licences. Water companies are labelled repeat offenders, as year on year they are fined for impacting the environment with unlicensed discharges of untreated sewage. Only last Friday South West Water was ordered to pay almost £40,000 in fines and costs for allowing sewage to escape into the River Dart near Galmpton in south Devon, after effluent entered the river last May and caused the closure of a shellfishery.

The 1976 EU bathing water directive is not designed to identify effectively the impacts on the environment from combined sewer overflows. It is useful in giving an indication of water quality over the bathing water season, but all that it really tells us is the water quality during 20 short periods over 140 days, and only in the most popular bathing zones, not at the points where water is most likely to be polluted, such as the mouth of a river or the nearest CSO on the beach.

The revised bathing water directive, which will come into force in 2015, will mean four years’ consecutive data being examined and water being measured against tougher standards. However, there will still be 20 samples, and many pollution incidents will fall between the gaps. I remain concerned that many CSOs are deemed not to have an impact on bathing waters, and so are licensed for even more frequent discharges—the licences do not contain a set figure.

The CSOs also discharge when a predetermined volume of water is being passed forward within the sewerage system. When that volume is reached, the CSO can be employed to release pressure from the system, resulting in raw sewage on beaches and in rivers more than 100 times a year, equal to the frequency in London. Those CSO discharges can also have an impact on the coastal environment. Our over-reliance on CSOs has resulted in the European Commission taking the UK to court over a breach of the EU urban waste water directive of 1991. The case has been heard, but we are still waiting for the judgment.

I support the Thames tunnel, the super-sewer or whatever we want to call it, for the environmental and economic benefits that it will achieve in London. The project is expected to add £70 to £80 to the average Thames Water waste water charge, which has been among the lowest in the country, and I recognise the problems that that would cause some people. Even with the Thames tunnel, however, Thames Water’s bill would rise only to the national average. The additional resources from the Government should allay some of the fears of the people whom colleagues have mentioned.

I also welcome the reduction for South West Water customers, but according to one estimate highlighted by the company itself, the cost of removing or further reducing the impact of CSOs in its region’s network would be about £500 million, which could add as much as £40 a year to the average bill in the region. If the Government propose to subsidise each South West Water customer by £50, the company should by its own evidence be able to afford to undertake that work from its current resources. I should like that to happen, particularly given the introduction of the new bathing water directive. Until that occurs, it is anathema for any Government to claim that we have bathing water of a high standard in this country. My experience, and that of other Members, has been that that is simply not the case.
