Water leakages: which company is the worst?

Posted by MereNews On May - 8 - 2012

Over three billion litres of water leaks from our water companies every day according to data obtained by the Guardian showing that over half of water companies are not required to reduce their leakages before 2015.

Despite the wettest April on record, millions of people across the UK are facing a hosepipe ban for the rest of the year and drought has been declared in southern and central England. Damian Carrington writes:

Ofwat and the water industry highlight a one-third reduction in leakages since privatisation, but over the past 12 years, year-on-year leakages have increased as often as they have fallen, suggesting no long-term downward trend.

The average annual customer bill for water has risen by £64 since 2001 and is now £376, while the companies collectively made £2bn in pre-tax profits and paid £1.5bn in dividends to shareholders in 2010-11.

The data from regulator Ofwat shows some suprising results by water company – more than half of water companies won’t have to reduce their leakages at all before 2015. The chart below shows how estimated water leakages have changed over time.

Here are some of the key points from the figures:

• From 1998-2011 there was only a 5% cut in leaks by the 21 water companies serving England and Wales
• 1.5% cut in leaks – the target for the next 4 years (to 2014-15)
• 10% – the target for the next 25 years according to Ofwat
• 11 of the 21 water companies have zero % leak targets for years up to 2014-15
• Southern water, which missed its leak target (again) in 2010-11 by 16%, is allowed to *increase* leakage by 6% by 2014-15
• 3.36bn litres of water a day are currently being leaked, and aiming for 3.24bn by 2014-15 – roughly 25% of all water
• Average bills have risen by £64 in last decade to £376 a year

The tables below show company targets up to 2014-15. Data showing figures for company estimates of total leakage (MI/d) from 1998-99 to 2010-11 can be found in the spreadsheet.What can you do with the data?
