CLIENT: Peabody
PROJECT: Coppabella Dredging

SCOPE OF WORK:

We were engaged to remove approximately 100,000m3 of product and return it back into the co-disposal. The dam was at capacity, and the process plant water was being contaminated by the silts and fines contained in the dam.

CHALLENGES FACED:

As the dam was at capacity, we were initially challenged by the deployment of the dredge. With a long arm excavator we were able to dig a hole that allowed the dredge to float.

ACHIEVEMENTS/OUTCOMES

Not long into the project we began to notice the materials being pumped to the co-disposal were returning to dam and a rate of 50% or more. Site were aware and had already begun the development of new co-disposal cell. Once we pumped to the new cell the return rate was less than 2%. The whole project was definitely a success, keeping the CHPP in clean water for processing.
