United Utilities has voiced concerns over a proposed gas storage facility, which it claims could leak into an underground sewage tunnel which runs under Blackpool.
United Utilities is now seeking assurances from Halite over the plan to store 900 cubic metres of gas in salt caverns near Preesall – formerly proposed by American company Canatxx.
In a document sent to Halite, United Utilities said: “A key concern of the proposed development would be to ensure our wastewater assets remained well protected from any gas leakage, which would occur through the fissured ground strata believed to exist underneath Wyre Estuary.
“The developer would have to satisfy sufficient investigation had been done to assure the development would not increase the risk of future explosions of gas impacting on the treatment facilities.
“This would also apply to the Fylde Coast Interceptor (sewage) Tunnel which runs the whole length of the Fylde coast from Manchester Square headland at the southern end of the Golden Mile, along the front up to Rossall School.
“The risk of gas escaping the caverns and entering the tunnel provides a clear route for passage of leaked gas all the way along the front to south Blackpool.
“Hence the development potentially puts at risk both United Utilities’ assets and properties/hotels in close proximity to the tunnel and the coastline.
