The site was assessed by one of our team, and a method statement and risk assessment drawn up. The culvert on the motorway was completely blocked. Water was unable to pass through the foul and storm lines due to a vast amount of stone, grit and materials.
In order to carry out these works with no disruption to traffic we decided to enter the culvert by confined space entry with our high powered suction and blowing DISAB vacuum excavation unit. The debris was collected with the DISAB unit and the material was removed to a sealed skip on site. This skip was disposed at an authorised disposal facility.
The culvert was fully cleaned with no disruption to the general public.
Sealing and repairs works on a grease bin consisting of rebuilding base damage and sealing fiberglass unit using structure injection and reinforcement.
Using the appropriate personal protective equipment, we cordoned off the work area with barrier tape and signage.
This was one of the larger reservoirs in the Irish Water network. AQS Solutions was commissioned to clean and de-sludge the reservoir for the first time in a while.
