Case Study – Confined Space Entry

Confined space entry to clear storm water lines.

Location Redbank
Date May 2020
Duration 2-4 Weeks

Lee’s Environmental is currently onsite cleaning out the stormwater drains at the Richard Cooks construction site for the new Goodman Fielder Distribution Centre at Redbank. As part of normal handover when a site is completed, stormwater drains require a clean out for approval.
Because the stormwater drains at this site are 2m deep underground, we brought out our Confined Space and Emergency Response Unit which contains all the equipment for our Confined Space Entry Certified technician to go down under the ground to access the stormwater.

The cleanout of stormwater drains requires one of our large 10,000L combo trucks with jetting heads capable of cleaning out 1.2m diametre pipes. The stormwater pipes at this site are extremely blocked with dirt, gravel and concrete slurry from the contruction site. The massive 3.2 Kilometers of stormwater drains would normally take one of our combo units only 2-3 days to clear, however due to the extremely blocked condition of the drains, the project has blown out over 2 weeks so far.

Fortunately, the combo unit we brought to site, nicknamed The Enforcer, may be the fastest, most powerful combo truck in Queensland and is fully capable of the difficult task with its 6300 CFM Vacuum pump able to pump out from a massive 18+ metres deep and its 180m long, 1 inch jet rodding hose can breakdown blockages in long pipes, shift firm sludges, and break up dirt at lightning speeds.

Our experienced technicians are going underground using Confined Space Entry gear and feeding the jetrodding pipe down into the stormwater drains.

The site involves a high level of health and safety requirements and all our technicians have been received site specific inductions. We are observing a 3m exclusion zone and as part of our standard operating predure, our confined space entry equipment has been certified and gas detectors calibrated.

Please contact us if you require stormwater drain cleaning or confined space entry.
