Overview
With increasing urban and agricultural development, water quality management has become a major issue for freshwater, estuarine and marine ecosystems. River floods, mine site water management, agricultural land and water management and urban, commercial and industrial stormwater and wastewater management all impact upon offsite water quality . The impact and fate of pollutants on these ecosystems is often dependent on the complex interaction of many hydrological and biogeochemical processes.
Quantifying relationships between stream water quality and catchment land uses is a major goal of many water quality monitoring programs. This is a challenging task that is rarely achieved through simple analysis of raw data alone. This presents significant challenges with information from appropriately designed monitoring studies coupled with appropriate analysis recognised as crucial for understanding process dynamics and for assessing cause– effect relationships.
Water Technology is a recognised leader in catchment water quality assessment and management, offering a comprehensive range of services. We have experience in all facets of catchment water quality management: from monitoring program design, implementation and review; from simple data analysis to complex state-of-the-art catchment water quality models. Project dimensions cover an expansive range from isolating the impact of runoff from different land uses on the Great Barrier Reef, to assessing the fate of landfill seepage on RAMSAR listed wetlands to developing water quality management strategies for urban developments. We combine leading edge technology with outstanding project experience to deliver economic and environmentally sustainable solutions.
Selected Projects
Ballina Salinity Infiltration Investigation
Client: Ballina Shire Council and NSW Department of Commerce
Water Technology was part of a team investigating salinity infiltration to the Ballina sewer network. The purpose of the study was to identify and prioritise the nature and extent of the capital works required to significantly reduce saline and ADWF. To maximize cost effectiveness, an investigation technique of spot testing followed by camera inspection was employed. This offered a substantially cheaper alternative to traditional in-pipe flow gauging operations to narrow down the pipe lengths for detailed camera inspection.

Corner Inlet Decision Support System
Client: West Gippsland Catchment Management Authority
Water Technology and Melbourne University were engaged to undertake a catchment audit to identify sources of pollutants and develop strategies to protect the ecological values of the RAMSAR listed estuary. The project team developed a comprehensive sediment and nutrient model (E2) of the catchments of Corner Inlet calibrated to event based water quality monitoring.
