United Utilities is set to host a drop-in event in Ambleside.
The event will give the public a chance to learn more about the proposed investment at the Ambleside wastewater treatment works.
The company says the investment aims to improve the water quality in Windermere.
The drop-in session will be held at Ambleside Parish Centre on Wednesday, November 6, between 2pm and 7pm.
United Utilities recently announced plans for an additional £156 million investment around the catchment, on top of the previously announced £41 million.
Projects at four storm overflows at Ambleside, Elterwater, Hawkshead, and Near Sawrey wastewater treatment works are set to begin in the coming weeks.
The proposed investment will reduce storm overflow operations from the remaining two sites in the catchment and improve treatment processes at nine wastewater treatment works, it is claimed.
Andrew Marshall, delivery manager for United Utilities, said: "As people begin to see work happening around the catchment, we know many will want to find out more.
"This drop-in event gives people the chance to come along and ask any questions they might have about our investment at Ambleside."
For anyone unable to attend the event, United Utilities’ information centre in Windermere is open Monday to Friday between 9.30am and 5pm.
