Our Treatment Solutions for Surface Water

Surface water, including rivers, dams and stream, is extremely vulnerable to contamination by pollutants including chemicals, bacteria, parasites and viruses. Like ground water, it can be easily treated and made safe for use by our specially designed treatment systems.



Surface water is any source of water located on the earth’s surface. This can include rivers, creeks, lakes and dams. It is more easily polluted than sea water and ground water, but is often located closer to where it is required. There is far more fresh water in ground water than surface water, but ground water is harder to access.

Surface water can become polluted via run-off events and as a result of wind-blown material. Common contaminants include microbiological contamination, chemical pollution, nutrients and sewage. Surface water will often have multiple contaminants of concern present meaning that multiple treatment technologies will need to be combined to treat the water to a potable standard.

Surface water treatment is important for agriculture, horticulture, industry, governments and communities. Moerk Water has extensive experience treating surface water sources and has a range of different technologies for producing clean water from surface water including membrane desalination, clarification filtration and UV disinfection.

Most Common Plants & Systems for Treating Surface Water

Our treatment plants are individually designed to meet the specific requirements to create a supply of water that is safe for drinking or use in commercial and industrial situations.

UV Sterilisation

Flow Disinfection is the go-to solution when you are treating biologically contaminated surface water. Reverse osmosis will remove all microbiological content from the water and concentrate it into the effluent stream and will also remove the salt.

Clarification Filtration

Clarification Filtration is a chemical/physical method to reduce the dirt load in the water. Fine particles below a certain size will pass through standard filters. Following clarification filtration, depending on the water quality required, the water can be further purified to reduce the salt load or remove any other contaminants of concern.

Iron Removal Systems

Moerk Water’s Iron Removal Systems remove iron from any water source, eliminating concerns about iron bacteria contamination, corrosion, and scaling. Our iron removal systems utilise aeration mechanisms and filters with an automated backwash to reliably removing iron from the water while keeping the systems hands-free and operating costs as low as possible.


Typically when we think of reverse osmosis we imagine large facilities that underpin a city’s water supply or small under sink units. However, in our context, we have adapted these membrane systems to be both transportable and optimised for whatever scale various agricultural and commercial concerns require.

Brackish Water Treatment

Moerk Water specialises in designing and building custom desalination plants and systems to treat various saline water sources to achieve water that is ready for commercial application and/or safe drinking water.


Moerk’s water treatment technology can convert a wide range of water types, including sea water, brackish water and contaminated water into safe drinking water that meets World Health Organisation water quality standards.
