Treatment systems for urban (WSUD) systems
Urban development can generate impacts on water quality due to chemical and pollutants from roads and roofs. Hard surfaces also cause water to runoff much faster, rather than soak into the ground. These impacts can result in what is referred to as “urban stream syndrome”. Constructed Treatment systems for effective removal of pollutants need to be designed to maximise the treatment processes specific to the target pollutant(s). Water Sensitive Urban design (WSUD) is an integrated approach to minimise the impacts of urban stormwater.
The State Planning framework through the State Planning Policy directs matters of “State Interest” that Local Governments must approximately integrate into any new or amended planning schemes for the respective area.
The State interest for Water quality is one of 17 State interests and is stated as “The environmental values and quality of Queensland waters are protected and enhanced” and requires local government to consider several policies including:
Water Sensitive Urban Design
Urban development can generate impacts on water quality due to chemical and pollutants from roads and roofs. Water Sensitive Urban design (WSUD) seeks to minimise this impact by integrating developments with a site’s natural features and promoting the integration of stormwater, water supply and sewage management.
Treatment systems complement, but do not replace the need for measures to prevent the loss of pollutants from the source, such as erosion control (e.g. pile fields, ground cover) or remove the need to implement nutrient, sediment, chemical and water best management practices. Best management practices are the essential first step in any treatment train to prevent or minimise pollutants entering the water system.
The ‘Living Waterways’ approach developed by Water by Design (Healthy Land and Water) is a best practice environmental management approach that assists practitioners and government to deliver enduring and affordable outdoor spaces which engage the surrounding communities.
