RESIDENTS living near to Ramsden Reservoir are being warned against bogus callers as improvement work starts at the site.
Yorkshire Water says work will not impact on water supply and is advising homeowners to be on their guard if they are approached by people claiming to be involved in the work.
The company are due to begin year-long work on the spillway at the reservoir.
As part of the work, recreation facilities and the picnic area around the site will be closed for safety reasons.
Nicola Senior from Yorkshire Water said: “We acknowledge quite a few people will miss the picnic area and the views from the dam, but a construction site can be a dangerous place and public safety is our paramount concern.
“The work is part of a modernisation programme which has included improvements at a number of reservoirs in Yorkshire.
“We hope people will appreciate the work is essential if we are to be sure of maintaining an efficient water supply in years to come.
“Although some of the usual routes will be temporarily unavailable, the long-term benefits outweigh the short-term inconvenience.”
As part of the modernisation of the dam, the new spillway will be constructed at the opposite side of the reservoir embankment to the existing one.
The current footpath across the dam will be diverted for safety reasons while Brownhill Lane, which runs along the eastern shore of the reservoir, will be closed to traffic.
The picnic area and car park on Brownhill Lane will also be out of bounds.
Preliminary work is expected to start next Monday, February 18, when the site will be closed off.
Yorkshire Water hope work will be completed next spring.
Customers and walkers can view plans for the proposed work at a drop-in at Hinchliffe Mill Junior and Infants School, Waterside Lane, Holmbridge, on Monday, February 11 from 4.30pm until 7pm.
Representatives from Yorkshire Water will be on hand to answer questions and talk about the project.
