United Utilities has launched an important study into the future of Cogra Moss – a ‘retired’ reservoir in west Cumbria.

Built in 1880, the reservoir ceased to be used as a water source for local homes and businesses in 1975 - United Utilities has continued to maintain the reservoir since then.

The reservoir, which is used by local fishing clubs, and is valued by local people as a place for recreation and relaxation, is subject to thorough safety inspections every 10 years by an independent inspection engineer. The most recent inspection, in 2014, identified that work was required to the embankment of the reservoir, along with further equipment upgrades to allow the reservoir to be drawn down in the event of an emergency or planned event.

Under the Reservoir Act 1975, the water company has a legal obligation to either carry out all the necessary remedial work, or to discontinue the reservoir by draining it – which would lead to the site being returned to its natural state - a process known as ‘renaturalisation’.

To help decide which of the two options to pursue, United Utilities has launched a detailed study. This includes an analysis of the costs and associated benefits of both options, plus a study of the environmental and ecological implications of each.

Gaynor Murphy from United Utilities said:

 “We know how passionately the community feels about Cogra Moss. Local people have been making their voices heard over recent weeks, and we’ve been listening.”

“We can assure everyone that no decision will be made until we have examined all the facts. We expect to complete the study in the next few weeks, and will hold a public exhibition before the end of September to share our recommendation with the local community.”

United Utilities aim is to find the best long-term solution for the site, by balancing the needs of wildlife and local people and the financial implications of each option.
