Sustainable Water Alternatives

While some of these technologies may not be applicable to the Manukau Harbour they may provide stimulus for the development of new applications to benefit the Harbour.

If you want to add to this list please email us directly. We are very interested in any alternative technologies that will stop the continued pollution of the Manukau Harbour


Singapore – PUB, Singapore’s National Water Agency

Managing the Country’s water supply, water catchment and used water in an integrated way.
PUB has embarked on a new shift in Singapore water management. The water agencies encourage everyone in the 3P (People, Public and Private) sectors to take joint ownership of Singapore’s water resource management. Known as the 3P approach, this is embodied in PUB’s tagline – Water for All: Conserve, Value, Enjoy.
Central to this new approach is the Active, Beautiful, Clean Waters (ABC Waters) Programme which will transform Singapore’s reservoirs and water bodies into beautiful and clean streams, rivers and lakes, creating a vibrant City of Gardens and Water. At the same time, these new community spaces bring people closer to water, so they better appreciate and cherish this precious resource. Over 100 potential locations have been identified for the implementation of the programme by 2030. Over 20 projects have been completed island-wide, and more will be rolled out between now and 2017 to various parts of Singapore.

The Deep Tunnel Sewerage System (DTSS), a 48-kilometer-long used water superhighway, conveys used water from the northern and eastern parts of Singapore to the centralised Changi Water Reclamation Plant for treatment before the treated used water is further purified into NEWater.
We are now planning for Phase 2 of the DTSS. Similar to DTSS Phase 1, DTSS Phase 2 will consist of four components: a deep tunnel (South Tunnel), associated link sewers, a centralized WRP integrated with NEWater facilities and deep sea outfall. It will cover the western part of Singapore, including the downtown city area and major upcoming developments such as Tengah New Town, and is targeted for completion in 2022.

Melbourne – Water Sensitive Cities

The changing role of the urban water sector

Guest Editorial Piece by Professor Tony Wong, CEO, CRC for Water Sensitive Cities Since the National Water Commission’s 2011 report on the future direction of urban water in Australia, the sector has intensified its strategising of its changing and future role across various fora. The Commission challenged the sector to “enhance its effective contribution to more liveable, sustainable and economically prosperous cities in circumstances where broader social, public health and environmental benefits and costs are clearly defined and assessed”. Therefore it will be necessary to for the water retailers to move beyond the traditional provision of ‘taps and toilets’ services of water supply and wastewater disposal to realise more multifunctional and flexible urban water systems delivering a broader range of services and outcomes for communities. Future urban water infrastructure will harvest and recycle an integrated mix of water sources (such as catchment water, stormwater, wastewater, greywater, seawater) bounded by principles such as minimising ecological footprints, through a more flexible combination of centralised and decentralised systems. It is this more complex systems approach that will enable a more sophisticated suite of social and ecosystem services such as water security, flood management, water quality protection of waterways, urban heat mitigation, enhanced biodiversity, amenity, social cohesion, catchment repair and overall improved system resilience – or coping capacity for future uncertainties.


Todd Wastewater Solutions

In 1989 Dr. John Todd, an internationally recognized inventor and a pioneer in the design and construction of ecological wastewater treatment systems, decided it was time to offer a cost-effective, renewable or what is now commonly referred to as “green” solution to the growing global wastewater crisis.
The company Dr. Todd founded, John Todd Ecological Design, has constructed dozens of Eco-Machine wastewater treatment systems based on Dr. Todd’s visionary ecological philosophy and award-winning practical designs in eleven countries on five continents around the world.
