WINEP Great Ayton STW Storm Tank Capacity

Afternoon All,

Let’s get up to date with WINEP Great Ayton STW Storm Tank Capacity:

Work to install the dewatering solution to allow the shaft sinking to restart commenced last week and is expected to continue for the next week or so. Once all the wells are in place, they can be connected together, and the ground water can start to be pumped down. This water should come out of the dewatering wells clean, but we will also run it through a Lamella Settlement Tank to make sure any remaining suspended solids have been completely removed before discharge.

Again, we do not anticipate either the abstraction or discharge of the water to have any negative effect on the surrounding environment and we have taken all reasonable steps to ensure that that is so.

We have also worked on our new solution to feed the new storm tank/shaft without the need for a sizable diversion of existing surface water pipes and new headwall on the riverside. This is all now agreed, and we have laid the first section of feed pipe and constructed a manhole.

Next, we will start on the interceptor chamber which will, upon completion of the works, divert the existing storm water for storage in the new storm tank/shaft until the flows have dropped sufficiently for it to be treated as normal.

In the meantime, we are installing temporary storm storage tanks and pumps which will triple the current storm water storage volume on site to address the chance of overflows whilst the permanent works are completed.

Thanks for taking the time to visit the portal.
