Sewage Pollution

I have repeatedly raised the issue of sewage dumping on the beach in my constituency in this Chamber. The Government continually use the excuse that it would cost up to £660 billion to upgrade our sewers, but the actual cost, over 10 years, would be £21.7 billion. Since privatisation, £72 billion has been paid out in dividends, so why are the Government not making the water companies meet these costs?
