Alluvium developing Sydney Water’s WSUD Policy

14.12.2014 - Posted by Richard McManus


Alluvium is currently working with Sydney Water on a significant project to develop a Water Sensitive Urban Design (WSUD) Policy for the organisation. The project ties in to Sydney Water’s corporate vision that “Sydney Water is the Lifestream of Sydney” and their strategy for enhancing the liveability of our cities. The WSUD policy will help Sydney Water link their programs to their customers’ objectives for a more liveable urban environment.

The project has involved significant consultation throughout Sydney Water, including numerous interviews and small group sessions. In early October, Alluvium facilitated a WSUD Symposium with four keynote speakers and 60 Sydney Water staff. The project has been very well-received and we are excited about where the project could lead.

Parramatta River Catchment Group launches the Our Living River campaign

8.12.2014 - Posted by Alexa McAuley
This week the Parramatta River Catchment Group launched the Our Living River campaign, which aims to build support for making Parramatta River swimmable again by 2025. Until the 1950s, swimming was a common activity in the River, even in the freshwater sections. However since that time, urban development of the catchment and increasing awareness of recreational water quality issues has seen swimming all but disappear.

While preparations for the campaign were underway this year, we've been doing a project behind the scenes to understand the feasibility, options, timeframes and potential costs. Our work has helped show how we could bring back swimming to the Parramatta River, and has already encouraged Parramatta Council to make Lake Parramatta a more accessible swimming spot this summer.

We’re really excited by this initiative, which connects our catchment management work to tangible community benefits, and it’s great to see that there is a real buzz about the possibilities for Parramatta River. The next step for us is to continue working with Parramatta Council to help them realign their catchment management activities with the concept of a swimmable river by 2025.

Sydney Park $10M urban water project and park upgrade

3.12.2014 - Posted by David Knights
The $10M Sydney Park urban water project and park upgrade in the City of Sydney is nearly complete. The Park now has an 850 ML/year stormwater harvesting scheme, with a series of bioretention and wetland systems to treat harvested flows. Also, existing ponds have been transformed to provide storage of treated flows, as well as to enhance habitat and landscape outcomes.

Alluvium developed the stormwater treatment and reuse designs, civil engineering and hydraulic engineering for the water project and Park upgrade (as part of an integrated design team with Turf Design and Environmental Partnership). We were also on site providing supervision throughout the construction process and to ensure that the stormwater elements were integrated with the major landscape upgrades to the Park.

Major new artworks are also part of the works, designed by Turpin and Crawford in collaboration with the design team. The artworks will celebrate the treatment of water occurring at the park.
