Portfolio of Lake Therapy

Sustainable solutions and transparency at every stage.

It takes more than just in-depth knowledge of highly complex ecosystems such as ponds, lakes or inland waterways to ensure that water therapy is successful: Even having the scientific expertise to create the best concept using innovative products is sometimes not enough. To us, it goes without saying that everyone involved in each stage of a water restoration project should operate with maximum transparency and traceability. 

Thanks to this approach, when you collaborate with OASE Water Technology on a project, you can rely on much more than just technical work by our experts and the expertise of OASE Water Technology partners. We provide comprehensive support throughout the entire process – from scientific water analyses and accurately determining root causes and location, to presenting economical solutions using our sustainable and effective water therapy techniques, to final reporting and monitoring.  

After all, we're all aiming for the same outcome: Ensuring that the water can once again be used to its full potential for a long time to come.

Analysis and survey

Our water therapy is based on having an accurate understanding of the current condition of the water. This includes evaluating purely physical features, such as the area, total depth, height of the free water column, depth of the sediment or the type and nature of any tributaries. We also analyse the water and sediment using all significant physical and chemical parameters and conduct a survey of all the flora, fauna and microbial life in the water. In general, collecting as much information as possible before starting the work – including a comprehensive history of the water – gives us a better basis from which to create a bespoke concept for the solution.


Our experts can gather all of the measurements and perform the analyses at our laboratory facilities: Alternatively, external service providers can also be commissioned to conduct the survey should you wish. We can also use existing data, as long as long as it contains all of the information required and the tests were conducted relatively recently. The ideal basis for our work is a combination of existing historical data and an analysis conducted shortly before the water is treated, as this allows us to gain a more accurate comparative insight into the effects of the treatment after it is administered.

Using lake mapping for analysis and visualisation

Sometimes a picture says a thousand words: Our lake mapping technology is an innovative method for collecting information about the water before it is treated and building a digital image of its condition. By using state-of-the-art eco sounding and ultrasonic measurement technology along with real-time geodata acquisition, lake mapping allows us to obtain an accurate image of the water – for example the size; the depth of the water; the depth, amount and consistency of the sediment; the amount of water flowing in; and the amount/weight of the algae present.


The benefits of this approach are twofold, as we are able to gather accurate data and then turn it into a 3D image: Lake mapping can generate an image based on 10 parameters, which can then even be integrated into Google Earth using a KMZ extension. The software can also generate an image of the desired results in advance, allowing existing problems to be presented in an image that is clear and easy to understand. Such information can be a valuable tool, for example when presenting the information at events or during official planning meetings with authorities.  

There are three versions of lake mapping available that offer various display options to choose from.

Ongoing monitoring

We offer long-term scientific monitoring to allow the effects of the treatment and the developments in the water to be accurately documented. This monitoring includes: the initial survey analysis; testing four weeks after the treatment is administered; four tests on a monthly basis following the initial tests; and final analysis and reports. All essential water and sediment parameters are recorded so that you – or the relevant authorities – can build an accurate picture of the effect that the therapy is having on the water and use this as a basis for the best possible before/after comparison. 

Bespoke product recommendations

Using the analysis and survey, we develop a treatment strategy and outline which products would solve the problem – or problems – identified. Depending on the conditions, this may be a single product or a combination of products – in some cases, an entirely new product is formulated specifically for the issues at hand. This entire preparation process is conducted in close collaboration with your local OASE Water Technology partner, who will later administer the treatment.  

Our product recommendation includes all of the important details you need to make an informed decision: the quantities required, a schedule, the method of application, data sheets, ingredients – and, of course, a detailed cost overview.  

We are happy to explain our recommendation in detail and answer any questions you may have.

Information for all parties involved

The innovative OASE Water Technology water therapy has already proved successful in many cases, but is still relatively unknown to authorities and the public. This makes keeping them informed and operating with full transparency all the more important.

If required, we can assist our customers by providing details about the process, products and application to authorities or associations in the form of information sheets or presentations. Our experts are also on hand to answer any technical questions immediately.  

What's more, we can help you inform local residents about the water therapy treatment, for example by installing project boards at the site or in the town hall, and create transparency for all other parties that are directly or indirectly involved, e.g. angling or water sports clubs, health authorities or fisheries agencies.

Minimally invasive application

Once all preparation work has been completed, all permits have been granted and the ideal schedule has been determined with the customer, the water treatment process can begin: This is carried out by a qualified OASE Water Technology Partner that has been involved in the project from the start and is familiar with all the relevant details about the water. Even at this point, our experts are still on hand to answer any questions at any time.


The entire process is simple and unobtrusive – but above all environmentally friendly. All it requires is going out on a boat, which can be manoeuvred almost silently and emission-free over the water thanks to its electric drive. Using precise GPS data and a device designed specifically for this purpose, the product can be applied specifically to the areas where it is needed. After the treatment has been applied, everything looks exactly the same as it did before – no banks destroyed by excavators, no sludge, no churned-up footpaths – so there's no need for any rectification work. 

Final reporting

Usually it's the results that count in the end – but we are also interested in the process: Our mission is to make all analyses and measures along the way completely transparent and easily understandable. Soon after we have finished the treatment, or after a period of your choice, we will provide a detailed report to present the results. Reporting can also be outsourced to third parties if required.
