Stormwater Harvesting: Good Maintenance Practice

Australian Open 2019 has ended. First few weeks in February Melbourne had little (if any) rain and IVWater took the opportunity to conduct annual maintenance clean out activities for stormwater harvesting infrastructure at Melbourne Olympic Park.

In collaboration with Cleanaway and Melbourne Olympic Park management all underground infrastructure components were inspected using CCTV and CSE to determine the extent of cleaning/maintenance required. The clean out procedure was carefully planned (and timed) to minimise the disruption of public activities. The whole stormwater harvesting system was inspected and tested and more than 30 tons of sediment and litter was removed from the GPT, various pits, pump station and detention and storage tanks. That also means that 30 tons of sediment and litter will not enter the Yarra river this year! Melbourne Park is now ready for another 12 months of operation until the next annual clean. All we need now is lots of rain!

Integrated Water Management Regional Workshops: Capturing the Potential of Stormwater

We have been working tirelessly together with IPWEA VIC and DELWP organising a series of four regional workshops "Getting Integration into the Integrated Water Management" including "Capturing the Potential of Stormwater" presentation by IVWATER.

The workshops took place in Colac, Maryborough, Narre Warren & Traralgon featuring presentations by state, regional, local and private sector stakeholders.

For details on workshops follow the links below:

Melbourne Water Stormwater Harvesting Guidelines Seminar
(Thursday 6th Oct 2016)

This seminar was organised by Melbourne Water Corporation (via Clearwater) for Local Government and Industry practitioners involved in planning, design, construction, operation and maintenance of stormwater harvesting projects within Melbourne Water jurisdiction.

Melbourne Water Guidelines (update)

As the licensing authority and waterway manager for urban waterways within the Melbourne region, Melbourne Water has developed draft technical guidelines for stormwater harvesting structures and is continuing to develop principles and rules relating to the volume, rate of harvest and location of stormwater harvesting. These rules and principles form an important part of overall resource management for stormwater in this region.

The guidelines are designed to provide proponents and engineering practitioners with guidance on Melbourne Water's requirements for stormwater harvesting schemes on Melbourne Water assets and recommended options for the design, construction, operation and maintenance of diversion structures. Melbourne Water Guidelines for Stormwater Harvesting have been formally released by Melbourne Water and are available on:

IVWater is proud to be part of the 5 years long development of these Guidelines that involved comprehensive industry and stakeholders consultation and addressing complex and challenging issues such as environmental/base flow requirements in the urban drainage systems in the context of stormwater harvesting. We congratulate Melbourne Water, all stakeholders involved and the Stormwater industry in general on the the release of this long awaited guidelines.

Sewer Mining and Stormwater Harvesting Facilities Tour, Melbourne Sports Precinct

Water recycling facilities tour at Melbourne Sports Precinct was organized by IV Water in collaboration with the Federation University, Melbourne Cricket Club and Melbourne Olympic Park Trust on Tuesday 22 September 2015. More details can be obtained on our Non-Commercial Projects page.

IV Water has received some great feedback in the form of a thank you letter from Federation University:

Operation and Maintenance of WSUD Infrastructure

Operation and maintenance of WSUD and stormwater harvesting assets presents some significant problems within the industry. Some excellent solutions have been developed to cope with the issues in maintenance and operation of such schemes over the past decade however these experiences are currently not well known within the industry. In an effort to capture the best practices in operation and maintenance of WSUD and stormwater harvesting projects and provide a forum for knowledge sharing around these issues IPWEAvic has organized a workshop on 3rd June 2014 at Banyule City Council. The workshop was fully booked in advance with more than 55 people attending on the day.

Capturing the Potential of Stormwater

Management of the urban water cycle in Australia has changed significantly over the past few decades.

Stormwater management philosophy has evolved from the conventional, but still important, flood mitigation paradigm, to the current runoff quality control approach. It is now progressing towards the harvesting and reuse concept whilst retaining the previous two targets.

Given the current interest in the uptake of stormwater as a resource (stormwater harvesting) and the on-going commitment to control and treat the run off prior to its discharge into the natural environment by application of WSUD - the Australian stormwater market is also set to grow in the years to come.

The pace that the stormwater market in Australia grows will, to a large degree, depend on the certainty that it can offer to the public, the clients and the government in delivering the stated objectives. In this paper the author looks at the current stormwater harvesting practice and highlights some of the issues that could facilitate the uptake of this valuable resource in Australia in the years to come.

Independent Verification Scheme for Stormwater Treatment Devices

Melbourne Water Corporation in recognition of the industry need engaged IVWater to prepare a road map paper on the development of an independent verification scheme for stormwater treatment devices and the IVWater Road Map report presenting the findings and conclusions from this study has now been released for public consultation via the Stormwater Industry Association (SIA) website:

Stormwater Harvesting in Urban Environments

Stormwater management philosophy in most developed countries has evolved over the last decades from the conventional but still important flood mitigation paradigm, to the current runoff quality control approach, and now is progressing towards the harvesting and reuse concept whilst retaining the previous two targets. Stormwater harvesting offers multiple solutions to urban water systems such as mains water demand reduction, water quality improvement and in many cases creek ecosystem health protection. Stormwater harvesting has been incorporated into the broad concept of integrated urban water management (IUWM) which emphasizes diversification of urban water sources in order to embed resilience into the whole of the urban water (Burn et al., 2011; Maheepala and Blackmore, 2008; Coombes and Kuczera, 2001). IUWM promotes stormwater source control through a number of engineering measures, generally known as water sensitive urban design (WSUD) in Australia, also called low impact development (LID) in the USA, and sustainable urban drainage systems (SUDS) in the UK. Numerous stormwater harvesting schemes are in operation in Australia with a number of medium to large schemes operating in Melbourne.

Australian Guidelines for Water Recycling (2006)

The Australian Guidelines for Water Recycling (2006) require water treatment technologies to be validated before the water recycling scheme is operational. The guidelines describe the concept of validation but do not specify how it should be done. There is currently no consistent approach to validating water treatment technology across Australia. As a result, validation of identical or similar technologies can often be replicated in multiple states/territories, causing unnecessary duplication of work for the regulators, as well as delays, inconsistencies and an increase in costs before a scheme is commissioned.

The primary purpose of Stage 1 of the National Validation (NatVal) project was to deliver a road map on how to develop a national validation framework for water recycling schemes in Australia, consistent with the Water Recycling Guidelines. The framework must be practical, feasible and accepted by regulators, water authorities and suppliers in all jurisdictions. Water Quality Research Australia was the project leader for this phase of the program. The final road map report and supporting material were received in December 2011 and signed off by the Centre in January 2012.
