Tank Stream, Sydney
Sydney’s Tank Stream is significant in Australia’s colonial history, but is now buried in stormwater drains. It is one of many lost waterways around the world that have been buried beneath our urban
areas. There are substantial economic, social and environmental benefits of daylighting these lost urban streams.
A new website developed by the University of Sheffield (UK) has been developed for practitioners, water managers, policy makers and anyone with an interest in river restoration and sustainable urban design. It is a resource of case studies from all over the world, collating information on the goals and outcomes of daylighting projects. This is helping to share knowledge and expertise across the world, connecting like-minded individuals, and demonstrating the benefits and challenges of daylighting urban streams.
Everyone is invited to browse the case study map and add new sites – even if they are only in the planning stage – and connect on Facebook.
After just over two years of very intensive activity, the Hawkesbury-Nepean River Recovery Program (HNRRP) is coming to an end, having successfully delivered its intended outcomes on time and under budget. The ﬁnal edition of HNRRP e-news reﬂects on some of the major achievements from the seven HNRRP projects and celebrates the great work that has been done to improve the health of the Hawkesbury-Nepean catchment. The Hawkesbury-Nepean river system frames the western edge of the Sydney Basin and is one of New South Wales’ most important natural assets.
The last edition of HNRRP e-news discussed how the Hawkesbury-Nepean River Recovery Program is meeting one of its key objectives – the prevention of an estimated 48.2 tonnes of nutrients (nitrogen and phosphorus) entering the Hawkesbury-Nepean river system each year. In the June 2011 edition of HNRRP e-news we look at our other key objective – securing 7.24 gigalitres (billion litres) per year for additional environmental ﬂows in the Hawkesbury-Nepean river system. You can also read about the HNRRP projects and how they are progressing as the program nears completion.
The coincidence of the Queensland Floods Commission of Inquiry and Information Awareness Month offers the opportunity to explore how well our communities are using information and knowledge in regard to natural disasters. In early January this year the media carried horrific images and stories of the loss of life and damage caused by flooding in the southern Queensland towns of Toowoomba and Grantham and in the cities of Brisbane and Ipswich. Surprise was expressed at how such severe events could have happened. But the reality is that these floods have their predecessors, as explored in the article Queensland floods: information, history and knowledge.
The Hawkesbury Nepean River Recovery Program (HNRRP) aims to help improve the health of the river system by reducing the amount of nutrients entering the river system and making more water available for environmental ﬂows. The March 2011 issue of HNRRP e-news explores one of these important objectives, looking at how the HNRRP is working to prevent an estimated 48.2 tonnes of nutrients entering the river system each year and discussing how this will beneﬁt the river. You can also read about the start of works for the Hawkesbury City Council South Windsor Efﬂuent Reuse Scheme and some interesting insights into other HNRRP projects.
