Working against the clock, we had to engineer a method of improving flow rate into the Southern Seawater Desalination Plant, Binningup

Dwellingup Water Main and Transfer Pump Station
When Dwellingup needed a water pipeline with minimal impact to the environment and community, we got our trenchers out and into gear.

Quinns DN1950 Main Sewer
The overall project consisted of approximately 5.2km of HDPE plastic lined DN1950 reinforced concrete sewer pipe, a wastewater treatment plant (WWTP), an ocean outfall and a further 1km of DN1950 sewer pipe to connect the WWTP to the ocean outfall.

Alkimos DN700 Distribution Main
The project involved the installation of 1.4km of DN700 MSCL Water Main in varying ground conditions utilising different construction methodologies.
Hill Street Water Main Renewal
The general methodology for construction is to duplicate the existing cast iron main with the appropriate size PE pipe alongside the existing main which remains live, and to tie in to the existing main at the end points to produce two live mains.

The project involved the installation of 560 metres of DN150 and DN200 PVC pipework. The project had a contract period of 8 weeks to tie in with the Shire of Katanning completing their own urban development works.

Client references for Pipeline projects
I am pleased to say that the operations team were extremely impressed with the quality of the asset that has been built.
The team that DM Civil placed on the project was excellent and the level of communication between Water Corporation team and DM Civil was definitely a key to the success of the project .
As a project team we are very pleased with the outcome, and also the manner in which it was achieved, where cooperation between the contractor and client created an environment where both parties achieved their goals.Marc Griffiths
Principal Project Manager, Water Corporation![]()
DM Civil embraced the Corporation's commitments to landowners and worked closely with the Corporation to ensure that construction was carried out in accordance with these commitments. DM Civil worked collaboratively with the Corporation to constantly adapt to the changing ground conditions and continue pipe laying in extremely trying conditions during the peak of the winter rains whilst ensuring all environmental conditions placed on the project were met.
DM Civil demonstrated an excellent environmental and safety work ethic throughout the entire project and responded immediately to any issue the Corporation raised. DM Civil take pride in their work and this shines through at every level in the company. I would like to congratulate the whole team for doing a great job and look forward to the next opportunity to work with DM Civil.Michael Mulrennan

Throughout the project, Russell and Paul demonstrated a high level of professionalism and commitment to quality, as did your entire crew. DM Civil staff were always suggesting innovative and cost saving ways to approach the project. They clearly were invested in ensuring that what work was done was work of which they could be proud.
It was a delight working with all the members of your team. Their creativity allowed us to achieve what would normally be unthinkable in terms of timing and quality. While the award was for project management, I wanted you to know that we couldn’t have done it without you and appreciate all you did.Nancy J Churchill
Director, Lowes Churchill & Associates Pty Ltd![]()
The works were completed in a professional manner, due attention to the contract restrictions including installation of the main through a sensitive environmental area and limited clearing in accordance with clearing permits.
The works were completed within the budget and programmed timeframes and DM Civil provided a cooperative and proactive attitude, in particular when implementing the above ground section of works. DM Civil's approach to occupational health and safety and quality items was first class.Sylvain Cabanel
Project Manager, Water Corporation / PPS Partnership![]()
The Pipe construction was managed extremely well considering the complexity of the work, the interface with the road construction and the tight time constraints. Any difficult issues were recognised early and managed efficiently on site.
All DM Civil personnel on site readily accepted and put into practice all the Alliance principles defined in our charter. Not only was the pipe constructed to a very high quality but the pipe team contributed to excellent overall results in environment, safety and public relations.David McGill
