Urban Water Management

Most areas proposed for development in the Perth, Peel and South-West regions have significant water resource issues. Urban water management strategies build onto traditional water management approaches to improve the quality and quantity of water resources post-development. Effective urban water resource management is achieved by integrating total water cycle management into urban development planning and design.

Strategic planning is important in total water cycle management and is a key focus in the State Water Management Strategy (Government of WA). The extent of investigation is determined by a sites condition and should accommodate the varying nature and scale between planning stages to keep information relevant. 

Urban water management is integrated into land use planning via water sensitive urban design techniques. The aim is to manage flood risk while maximising water re-use, efficiency and recycling with structural and non-structural controls for both existing and proposed urban development.

Bioscience has expertise in all aspects relating to Urban Water Management Strategy, particularly Local Water Management Strategies and Urban Water Management Plans. We incorporate water sensitive urban design objectives and storm water management principles in land use planning to achieve better water management practices.

 

Groundwater Modelling

Groundwater Modelling Groundwater monitoring and modelling programs are primarily needed to assess the current state of groundwater resources in regards to water quality, Average Annual Maximum Groundwater Levels (AAMGL) and direction of flow for urban and industrial developments.  Such investigations are conducted by Bioscience as part of an Urban Water Management Strategy (particularly in areas were the watertable is within 1.5m of the natural surface) or during Wetland Investigations in regards quantifying wetland boundaries.   

Depending on the specific site requirements, groundwater is usually monitored for up to 2 years, before sufficient data is available to accurately model using appropriate analytical and/or numerical groundwater modelling software such as Modflow®, HydroGeoAnalyst 2009®, and AquafierTest 4.2®.

Aquifer Testing

With water in rivers, wetlands and aquifers becoming less freely available for human use, regulation and licensing of remaining resources becomes more stringent. Our background in agriculture and horticulture, and our knowledge of water quality and hydrology and water use efficiency means we are ideally placed as an effective interface between users and regulators.

We organise and conduct aquifer pumping tests to evaluate and characterise bores and aquifers in order to determine any impacts on other users or the environment, and to determine sustainable yields. Aquifer pumping test are among the most expensive field tests in hydrogeology; it is therefore crucial to seek the advice of experienced professionals. 

Bioscience conducts aquifer tests in accordance with the Australian Standard 2368 “Test pumping of Water Wells”.  The data generated from these aquifer tests are then used to generate groundwater models and/or evaluate the efficiency of a proposed production well, using various software programs such as Modflow®, HydroGeoAnalyst 2009®, and AquaferTest 4.2®.  Hydrological Reports, produced to the requirements of the Department of Water then contribute to the important accumulating archives of the state water resources.

Licensing

Groundwater Licences are required for all commercial users of groundwater and artesian groundwater wells in Western Australia. This requires obtaining exploration licenses and abstraction licenses. The amount of detail required by the Department of Water depends on location and on the volume of water required.

Bioscience can assist with the application of a groundwater licences under section 5C of Right in Water and Irrigation Act 1914, from an initial desktop investigation, supervision of bore drilling and equipping, then testing bores. Data and logs are reported in a detailed Hydrogeological Assessment and associated Operating and Management Strategy to the requirements of the Department of Water.

Annual monitoring, analysis and reporting services are provided to many of the state’s largest water users.
