Wick Station

Drainage Case Study

QTS were contacted by NWR to look at a problem at Wick Railway Station in May 2015. There was an issue with the existing interceptor tank which was no longer working properly and QTS were asked to investigate. We initially carried out a CCTV survey to ascertain where all the connections were coming from and to prove connection to the tank. We also had to find out if there were any outgoing pipes and if so where did they outfall.

Having done all of this and providing a report showing nothing was running into the tank other than rainwater we were then asked to seal the existing tanks inlets and outlets to stop rainwater filling it up as it was costly to continue to empty it. Water was ponding around it and the ground area was sodden. We dug out all of the soil around the tank and replaced it with pea gravel and stone wrapped in terram. We fitted new lids and concreted them in place and sealed the top of the tank to prevent water ingress. The works were completed on time and within budget.
