Bondi Beach stormwater harvesting scheme
Concept design, detailed design and documentation
Waverley Council, 2011


Equatica completed detailed designs and construction documentation for a stormwater harvesting and reuse scheme at Bondi Beach. Treated stormwater will be used for toilet flushing and irrigation at the site. The project also includes a bioretention system as an aesthetic and functional element of the scheme, to make some of the stormwater harvesting infrastructure visible at the surface of the site and improve the opportunities for education and public engagement. Construction was completed in 2011, with Equatica providing construction services and assistance with project approvals.

Blacktown Showground redevelopment
Concept design, detailed design and documentation
Blacktown City Council, 2011


Equatica worked with Blacktown City Council and McGregor Coxall to develop designs for the revitalisation of Council's Blacktown Showground. The site will also highlight Blacktown Council's commitment to sustainable water management. Equatica designed stormwater treatment and harvesting systems including a wetland, bioretention system, 1,000 kL storage tank and connections to toilet flushing and irrigation systems.

Echo Point stormwater harvesting and reuse project
Concept design, detailed design and documentation
Blue Mountains City Council, 2009-10


Equatica has completed concept and detailed designs for a stormwater harvesting scheme at Echo Point, and construction has recently been completed. Stormwater is harvested from nearby streets and treated in a bioretention system within the road at the top of the Echo Point lookout. A storage tank is integrated beneath the bioretention system. Treated stormwater will be used to flush the toilets at the site's busy toilet block, saving approximately 2 ML of water per year.

Stormwater Harvesting Scheme for the Crest sporting complex
Concept design review, detailed design and documentation
Bankstown City Council, 2009


Equatica reviewed an initial concept design and then completed detailed designs for a stormwater harvesting scheme at Bankstown’s Crest sporting complex. The stormwater harvesting scheme involves diversion from the underground stormwater system, storage in an existing open pond, treatment and reuse for sports field irrigation. Equatica’s review identified key improvements to the initial concept design, which have made the scheme more robust and cost-effective.

Hudson Park stormwater harvesting and reuse scheme
Concept design, detailed design and documentation
Strathfield Municipal Council, 2010


Equatica is currently completing detailed designs for a storwmater harvesting and reuse scheme at Hudson Park in Strathfield. Hudson Park includes a golf course, driving range and oval, and is currently Council's thirstiest site. Saleyard Creek runs through the site in an underground channel, and the stormwater harvesting scheme involves extraction of stormwater flows from the channel for treatment, storage and reuse within the park. A key aspect of the design is that baseflows will be preserved within the channel, as they are needed to supply a harvesting system downstream at Airey Park.

West Circular Quay stormwater harvesting and reuse
Concept design, detailed design and documentation
With the NSW Government Architect's Office for Sydney Harbour Foreshore Authority, 2010


The Government Architect's office is currently preparing designs for the revitalisation of West Circular Quay, including First Fleet Park and the Museum of Contemporary Art forecourt. As part of this project, Equatica is working on detailed designs for a stormwater harvesting and reuse scheme at the site. Treated stormwater will be used for irrigation, avoiding future mains water consumption of approximately 3.5 ML/year. A key challenge at this site has been gathering information on the existing storwmater network, some of which dates back to the 1800s. Equatica has worked closely with the services survey team to gather the relevant data.

Mason Park stormwater harvesting and reuse scheme
Concept design, detailed design and documentation
Strathfield Municipal Council, 2009


Equatica completed concept and detailed designs for a stormwater harvesting and reuse scheme at Mason Park in Homebush. The project involves harvesting stormwater from an adjacent Energy Australia site, and conveying it to an underground tank within the park for treatment and reuse. A key part of the project involved liaison with Energy Australia to arrange for the stormwater diversion to take place from their property into the neighbouring park. The project is currently out for tender, for construction in 2010.

Peace Park Stormwater Harvesting and Reuse
Concept and detailed design
City of Sydney, 2009


Equatica investigated potential stormwater harvesting options to provide water for irrigation of Peace Park and nearby community gardens. The investigation looked at the feasibility of harvesting from various water sources, including roof runoff from adjacent buildings and stormwater from adjacent streets. The investigation also looked at storage options. Following the feasibility investigation, Equatica was engaged to complete detailed design and documentation of the preferred scheme, and construction was completed in 2010.

Stormwater harvesting strategy for Mildura’s Riverfront Park
Mildura Rural City Council, 2009

Equatica completed a stormwater harvesting strategy for Mildura’s Riverfront Park. The stormwater harvesting strategy forms one component of a masterplan for a major upgrade of facilities at the park. The stormwater harvesting strategy involved feasibility assessment, concept-level analysis and investigation of funding opportunities.

Rushcutters Bay stormwater harvesting project
Detailed site investigations and approvals
City of Sydney, 2009


Equatica assisted the City of Sydney to implement a stormwater harvesting project at Rushcutters Bay Park. Equatica reviewed designs for the stormwater diversion and gathered additional information on stormwater invert levels and other services on site. Equatica also undertook water quality sampling and helped organise Sydney Water approvals for the project. The image on the left shows a CCTV survey being completed for a sewer adjacent to the stormwater diversion.

Meadowbank Park stormwater harvesting and reuse scheme
Concept design, detailed design and tender documentation
City of Ryde, 2009


Equatica undertook a strategic assessment of sustainable water supply options for Meadowbank Park, including stormwater, wastewater and groundwater. This involved estimation of future irrigation demands, analysis of various alternative sources, and water balance modelling for each option. A workshop was held with Council where stormwater harvesting was identified as the preferred option. Equatica then completed concept and detailed designs for the stormwater harvesting scheme, including storage, treatment and distribution infrastructure. The scheme will supply water for more than ten sports ovals.

Prince Alfred Park stormwater harvesting and reuse
Detailed design review and documentation
City of Sydney, 2009


Equatica reviewed a stormwater harvesting scheme proposed for Sydney’s Prince Alfred Park, and put forward design amendments that would improve the feasibility, reliability and cost-effectiveness of the scheme. Equatica’s review included catchment analysis to determine the most optimal harvesting scheme for the irrigation of a sports oval and lawn area. Equatica then worked collaboratively with the multi disciplinary design team and the City of Sydney to complete detailed designs and specifications for the stormwater harvesting works, including stormwater diversion, storage and treatment systems. Construction is currently underway.

Sydney Park / Munni St Catchment Stormwater Harvesting and Reuse Project
Concept and detailed design
With AECOM for the City of Sydney and Sydney Water, 2008-09


Focused on Sydney Park, this project assessed stormwater, groundwater and leachate options for local and regional non-potable water supply. The project involved an initial water balance model to determine flows of each water source through the site, as well as modelling of the series of five existing wetlands within Sydney Park. This identified the need for greater water within the wetlands, and the potential to treat stormwater through the wetlands for reuse in irrigation or in local industry. The WSUD Strategy, concept and detailed designs were delivered by David Knights. Detailed design was completed by Equatica in collaboration with Sophie Spinks at AECOM.
