Sunraysia Environmental provides solutions for improving the viability
and profitability of clients and businesses.

Irrigation Approvals

Regulations for irrigation developments vary from state to state and often within states. We have assisted irrigation development on green field sites in most states and territories, and are skilled in soil survey to determine crop suitability, and in getting your project through the maze that is the approvals process. Our strength is that we run an integrated process: Step 1: We ensure you select the property that is best for your enterprise. Step 2: We co-ordinate the assessments and approvals to gain regulatory sign-off in the shortest time. We get your approvals faster so you can start development sooner, saving you significant time and money.

Environmental Approvals and Compliance

Development of land or a change in land use often requires regulator consent and/or a license. Our speciality is knowing the approvals process intimately, understanding the site specific, local and regional issues and targeting the “show stoppers” first.

We are well regarded by regulators for providing unambiguous reports that meet their requirements. This means they rarely need to seek additional information, which avoids costly delays for our clients. 

Contaminated Site Assessment and Remediation

The contamination of land can have catastrophic long term impacts by poisoning humans and destroying the natural environment. Don't buy a problem. Let us determine if your next land purchase or development site is contaminated. We can also determine the extent of any contamination and advise whether clean-up to the required level is a financially viable option.

Industrial Wastewater Disposal & Re-use

On the driest continent, it seems crazy that we have the term "waste" water. We work with wineries, fruit processors and municipal water authorities to find the most effective use for water that is a by-product of their processes. It has been regarded that "waste" water has no value and is disposed of with minimal thought to gaining additional benefit from a resource that has already been paid for. We show clients how to view this water as a resource so it can become an earner on the balance sheet and not just a cost for disposal. 

An recent example is a large winery that for years has discarded their waste water. With our expertise, they have planted a 20 ha vineyard using that same water to grow grapes to be put through their winery. By using our service, we helped create a win win situation for both the winery and the environment.

Soil Surveys

Regardless of what you wish to do with land, soil surveys are an insurance policy. When deciding which property to buy or changing a land use, a soil survey will determine whether the land is suitable for your proposed enterprise. Besides identifying soil constraints, we may be able to help overcome limitations such as poor root or water penetration. With more than 150,000 ha surveyed for various land use changes, we are well placed to help you make the best soil based decisions.

Site Salinity Management Plans

High levels of salt in the soil can cause failure in most building materials and make gardens look ugly. Getting us to determine salt levels in soil and groundwater pre-development means the developer can undertake any drainage or preventative building strategies from the start. This will avoid expensive and disruptive retrofits, warranty claims, unhappy customers and poor publicity. Our key output, a Salinity Action Statement, clearly states what needs to be done to prevent salinity impacting on your next residential development.

Aquatic Ecology & Aquaculture Services

Constructed Wetland and Reedbed Wastewater Filtration Technology

Constructed Wetland and Reedbed Wastewater Filtration Technology.


Constructed Wetlands: shallow, permanently wet substrate growing aquatic plants, Constructed Wetlands mimic the bio-filtration action of a natural wetland system. The plants trap & retain large amounts of solids, particulates and dissolved constituents. Providing habitat for native wildlife is an added bonus.


Horizontal Flow Reed-beds: used for larger flow rates and in tertiary treatment regimes. Effluent gently flows through a mass of reeds. This type of wetland can have higher biodiversity with amphibians, invertebrates and bird species present.


Vertical Flow Reed-beds: used where space is restricted, effluent is periodically sprayed over the surface media. The water percolates down through the gravel substrate and the reed’s root systems, where nitrified bacteria breaks down the organic substances. The cleansed water is collected in pipes below the reed-bed.


Natural Plant Process: removal rates include; 70—90% of Biological Oxygen Demand, 60—90% of Suspended Solids, 40—90% of Nitrogen, eradication of faecal coliforms and seasonal Phosphorus removal.


Energy requirements are minimal, particularly if the design includes a gravity feed input.
