Thames Water has today refuted claims by the former Ofwat chief that the company's plans for a 'super sewer' are overpriced.
The company has hit back, saying all other suggested options would cost more, and the new network is desperately needed to ease pressure on the current system, which was built for a much smaller population.
*Thames Water says: *
The Thames Tideway Tunnel is needed to give greater capacity to a system built in the 1850s to take both sewage and rainwater. London's population growth and the covering over of open land which could once absorb rainfall mean that a system designed to discharge to the river only occasionally, after exceptionally heavy rainfall, now discharges untreated sewage to the river on average once a week.
Thames Water also stressed the company hasn't asked the Government for a loan to for the works. It says the company is funding and delivering £2.7bn of it's £5.4bn programme to clean up the Thames as 'business as usual'.
