Queensbury Tunnel Repairs

Client:Hammond ECS
Flow Rate:120m³/hr

Background

The Queensbury Tunnel stands as a monument to the determination and courage exhibited by railway engineers during the Victorian era.

The historic former railway tunnel is now closed, derelict and flooded. It also has the dubious title of the ‘UKs most dangerous tunnel’.

Hammond ECS are tunnelling specialists who were tasked to assess the tunnel’s condition and report on viability of opening it as a cycle way, or alternatively permanently sealing it up.

The Overall Objective

The tunnel required de-watering before discharge to a nearby stream. The water had very fine solids which would require treatment before discharge and the water was being pumped 24 hours a day 7 days a week.

Solution

Siltbuster installed a full treatment system capable of treating 120m³/hr that would enable the solids to settle to ensure clear water would be discharged.

The Environment Agency attended the site regularly due to previous issues with cloudy water. The Siltbuster system was able to reduce the Total Suspended Solids from 92mg/L to below 11mg/L.
