Yorkshire Water is asking customers for their views on the company’s spending programme for the next few years.
The company is putting together its business plan for 2015-2020.
The plan, which will be submitted to industry regulator Ofwat in December for its approval, will detail exactly where investments will be made and ultimately how much customers will be asked to pay.
Ideas include cutting leaks and pollution, reducing risk of sewer flooding to hundreds of homes, and reducing carbon dioxide emissions.
Yorkshire Water is in the middle of an £1.8 billion investment, due to be finished by 2015, which includes a £78 million upgrade of Blackburn Meadows treatment works.
Richard Flint, Yorkshire Water chief executive, said: “We’re asking customers how they want to see us spending their money.”
The public can visit the website www.blueprintforyorkshire.com to comment on the plans.
Yorkshire Water will also hold a drop-in session for customers on Fargate in Sheffield, on Saturday, August 31.
Some funding for the investment is coming from increased charges, with average water and sewerage bills rising by £12 in 2013-14.
