Catchment Management

We bring together science and information on natural resources and community characteristics, to develop sustainable social, economic and environmental outcomes.

 

Evaluation of land management practices associated with pathogen loads within Myponga Catchment

Project managed and delivered information on land and agricultural management practices associated with pathogen loads within the Myponga Catchment. The information was used to support catchment modelling and to better inform SA Water’s understanding of risk to this drinking water supply.

Screening Assessment of Effectiveness of Catchment Barriers to Reduce Cryptosporidium Risks to Water Treatment Plants

naturallogic has been engaged by the SA Water Corporation to provide an assessment of the potential for catchment barriers to contribute to a reduction in cryptosporidium incident risk at its Happy Valley, Anstey Hill and Hope Valley treatment plants. This Stage 1 ‘screening level’ assessment is incorporates relevant water quality information, land use / land management practice knowledge, fate and transport estimates, mitigation options and potential log removal capacities for these systems

 

Catchment Works for the Reduction of Pathogens in Drinking Water Supply Catchments

naturallogic has been engaged to provide strategic advice to the Upper Torrens Land Management Program to deliver catchment works for the reduction of pathogens in drinking water supply catchments. The consultancy focused on the development of partnerships with SA Water, the public water authority, and the provision of advice regarding catchment delivery models, stewardship management and ensuring investment control through the development of appropriate funding agreements.

 

Public health issues associated with stock accessing waterways upstream of drinking water off-takes

naturallogic is supporting Water Futures Pty Ltd develop a report for the Victorian Department of Health on the public health issues associated with stock accessing waterways, with a focus on pathogen management. The report has reviewed background documents with regard to riparian management and environmental legislation and has provided scientific bases for the risks associated with stock access. An evaluation of risk mitigation measures, including fencing watercourses, exclusion areas upstream of drinking water off-takes and the management of juvenile stock is also provided.

 

A review of the Waste Control Project for Adelaide Hills Council

The Mount Lofty Ranges Waste Control Project was initiated to audit on-site wastewater systems for risk to drinking water supplies and facilitate system upgrades as appropriate. The project has now been running for 10 years, with 2460 properties audited and 689 failing systems upgraded. naturallogic was engaged by Adelaide Hills Council to review the subsequent water quality benefits (with a focus on virus loads) and assesses the residual risk of the on-site systems to drinking water quality within the region.

 

Emigrant Creek Catchment Management Plan

naturallogic and Water Futures Pty Ltd has developed the Emigrant Creek Catchment Management Plan for Rous Water.
The plan has been developed by completing the following actions:
• Preparing a written description of the catchment and source water.
• Setting water quality objectives for raw drinking water and ecosystem health.
• Assessing source water quality against those water quality objectives.
• Assessing risks to water quality within the catchment in its current state.
• Identifying future actions for Rous Water and stakeholders to reduce risks.

 

Kersbrook Creek Water Quality Improvement Project: Pathogen Reduction

naturallogic was engaged (SA Water) to develop and undertake this project to examine the feasibility of and develop a spatially targeted mitigation plan for implementing an accelerated pathogen reduction effort (primarily stock exclusion from watercourses) to achieve desired reductions of pathogens in the Kersbrook Creek sub-catchment (located within the Torrens Catchment).  The project also provides a robust quantitative monitoring and evaluation plan to report on the pathogen water quality outcomes of the mitigation program. This project is a ‘proof of concept’ to evaluate of the effectiveness of the catchment, based pathogen reduction efforts before a wider program would be rolled out to other catchments in the Mount Lofty Ranges.

 

Public health issues associated with stock accessing waterways upstream of drinking water off-takes

naturallogic has supported Water Futures Pty Ltd to develop a report for the Victorian Department of Health on the public health issues associated with stock accessing waterways. The work was focused on pathogen management and reviewed background documents with regard to riparian management and environmental legislation and has provided scientific bases for the risks associated with stock access. An evaluation of risk mitigation measures, including fencing watercourses, exclusion areas upstream of drinking water off-takes and the management of juvenile stock was also provided.
