Yorkshire water contacted me today with the following email to give an update on the works currently being undertaken in Bishopthorpe.
Repair at Junction of Maple Ave / Beech Ave
We are in the process of trying to isolate one of the two mains, which is damaged at this location and once this is achieved this will significantly reduce the amount of tanker movements in the area. Unfortunatelt there could be one or two more nights of tanker movements. At this location, we will continue to have a presence 24/7, until the works are completed.
We are current completing our survey works in the road - to give our team a clear understanding of the location of existing services, ground formation and other pertinent factors that we need to account before prior to making a repair. Once this investigation work is complete, our team will immediately commence the repair works.
At this stage, we expect the repair works to commence early next week (w/c 24th Oct) and may take 1-2 weeks to complete. We'll have a much more
definitive idea of the extent of repairs and timescales once our survey works are complete.
We appreciate that the over-pumping arrangement and frequent tanker movements are a disturbance. At this stage however these are critical in
enabling our team to complete the works as quickly as possible, whilst minimising any further disruption to the local community. As soon as the extent of works is known, we'll be writing to all in the area to advise of our intentions.
Repair at Keble Park North
At this stage, our engineers are in the progress of determining the best solution for the works required to make the repair at this location. The works here may involve two elements of works;
i) Necessary amendment to the support structure that supports the pipe at this location (known as a thrust block) - the extent of this repair is
dependent on a number of complex equations which our engineers are in the process of completing. The outcome of this assessment will determine the
size of the operation required to make the repair - it is our best intention to keep this to an absolute minimum if possible.
ii) In addition to this, we'll be internally resealing the pipe through a process known as 'patch lining', which is the least disruptive and unobtrusive means of making a repair; however, given the size and pressure of this particular pipe, we are waiting on a specialist material to arrive from Germany, which is expected to be delivered towards the end of next
week;
Any repairs will follow thereafter.
At this stage we expect works to commence from w/c 31st Oct, and could take 1-4 weeks; until we determine the extent of the repair, it is difficult to provide a definitive timescale.
Please rest assured that we understand the frustrations with the temporary measures employed by our team in the short-term. We will do our utmost to minimise any further tanker movements and pumping arrangements at the earliest opportunity, although both measures are critical to addressing the issue.
