Key services for Wastewater Pipeline and Infrastructure
Wastewater pressure mains
DM Civil specialises in the construction of Water Corporation assets including wastewater pumping stations, from Type 10 to Type 360. We are regularly invited to price the deepest and most difficult ground conditions, high risk installations. Our experience in piling and grouting of excavations, as well as dewatering in environmentally sensitive environments, has established us as a preferred contractor for this work.
Wastewater pumping stations
Whether standalone or in conjunction with a wastewater pumping station, DM Civil has the experience and qualified staff to construct pressure mains in any material and in any ground condition. We are a Water Corporation Critical Services Panel member for plastic welding of HDPE pipe and we are equally qualified to install rubber ring jointed PVC.
wastewater treatment plants
DM Civil has constructed all categories of treatment plants in the metropolitan area as well as regional. Whether the client is Water Corporation or Department of Communities, we have the capability to construct concrete oxidation ditches, lined ponds or mechanical and electrical installations.
