The London Assembly has today set out a number of concerns about Thames Water’s proposal for a new tunnel to reduce the amount of untreated sewage flowing into the River Thames each year.

Morgan Sindall Group plc, the construction and regeneration group, has a £3.6bn forward order book in place and said it is “well positioned to meet the challenges and opportunities in 2011 and beyond.”

Thames Water has made significant progress at Mogden Sewage Works in west London, which is undergoing a £140m upgrade to reduce the amount of storm sewage that overflows into the River Thames following heavy rain.
