Work is continuing at a controversial £5m reservoir project.
And disruption may be caused to some residents in Marsden, when two cranes are delivered as part of the work to replace the historic Spillway at Butterley.
The machinery will be delivered during next week and the one after and may result in “a small number of customers” on Binn Road having to move parked cars during hours of delivery.
It is the latest news regarding the Yorkshire Water renovation project that has been contracted out to Mott MacDonald Bentley (MMB), who will begin the main construction phase in May.
Staff will raise the spillway walls and replace the steep section (towards the middle of the spillway) with a straight slope to ensure flood waters are contained within the channel.
So far, they have been working to improve site access routes, set up a site compound, install fencing and implement localised footpath and bridleway diversions.
A spokesman from Yorkshire Water apologised for the “inconvenience” caused by the works, which has led to the reservoir access road from Binn Road to be closed during working hours.
Following reports of children entering the construction site in March, Yorkshire Water has also sent education guides have been to Marsden Junior and Infant School to talk to the children about the dangers of entering them, the water cycle and the project, which is due for completion in summer 2017.
The stone spillway was designed by Thomas Hawksley in 1906 but a previous inspection of the spillway by an independent Panel Engineer highlighted the need to adapt the spillway to ensure it continued to meet with legislation, in particular, the Reservoirs Act 1975.
Original plans to replace the spillway were fought by many local residents and conservationists.
They feared the historic stone would be replaced with concrete.
Yorkshire Water amended the plans and they have now been approved.
