March Construction Project Hamilton

The Requirement

Condor was contacted by March Construction to help with a contaminated dewatering requirement that consisted of dealing with heavy hydrocarbons in the groundwater. The job at hand for March Construction was to construct suitable ground works for Kiwi Rail to extend their workshop. Over the year’s hydrocarbons had leaked out of old tanks and oil spills into the ground had come in contact with the groundwater.

The Solution

Our Condor Sand Trap WTS unit was recommended for this project with a lamellar clarifier, along with our industry-leading hydrocarbon filter pads which the hydrocarbons will adhere and let water drain through. Our oil skimmer was also fitted to the system to skim off heavy floating hydrocarbons in the water. PAC was dosed prior to the water coming into the WTS unit to help settle out the heavy soiling in the groundwater being pumped into the system.

The Result

The unit was delivered to the site and set up, commissioned by Condor Staff. Testing was done to make sure discharge into the stormwater was compliant before leaving the site. A handover was done to the March Construction site manager to go over the management of the WTS unit, controlling the dosing PAC pump, and how to change over the used hydrocarbon filter pads before leaving the site
