Rochedale Water Main Project Edit

Trunk mains

Whether it’s sewer or water, trunk mains are critical infrastructure.

Diona has been delivering trunk mains for over 20 years using bores, micro tunnels, deep trenching and conventional methods. Our ability to deliver technically challenging projects within tight timeframes has seen us work on key projects across Australia.

Distribution

Diona has successfully delivered hundreds of kilometres of water, recycled water, and sewer distribution infrastructure over the last 30 years. We hold framework agreements with WaterNSW, SA Water, Queensland Urban Utilities, Logan Water Alliance, Hunter Water and numerous councils.

From inception to completion, and everywhere in between, our community sensitive teams deliver solutions.

Pump Stations

Pump stations encompass significant civil works, piping and mechanical, electrical and control works.

Diona’s award winning teams have delivered pump stations to 25m depth in highly constrained urban site conditions. In fact, we have delivered pump stations to Sydney Water, Queensland Urban Utilities, Hunter Water, Ballina Council, Lismore Council and many others.

Whether its sewage, water or reclaimed effluent, and regardless of the delivery methodology or capacity, Diona always delivers.

Renewals

We appreciate that working with renewals is different. Our operating teams are experienced shut-down program delivery managers. Working with operations and network staff to achieve the right outcome is central to what we do.

Whether it’s a pump station, civil structure, or other network asset, our teams will work with you to devise and deliver the best possible solution.

Despite these works being carried out under difficult conditions and at night, your team worked closely with SWC and WCG to complete these works safely with minimal disruption and inconvenience to the surrounding businesses and the general public.

I would like to thank the Diona team for the excellent collaborative delivery of the Powells Creek Naturalisation project. There were significant challenges throughout the project which Diona resolved with Sydney Water and all the relevant stakeholder to ensure an outstanding outcome for the community. The team did an excellent job.
