Most of the natural and manmade lakes and dams are subject to the gradual accumulation of organic waste material at the bottom. Logs, dead animals, storm washouts and other materials settle at the bottom and slowly build up a graveyard of unhealthy mass which is characterized by its total lack of oxygen, and consequent support of anaerobic pathogenic life. This accumulation may progress to the point where the whole lake dies. The dirty constitution and resulting odor makes such water unattractive and useless for marine life, recreational purposes, and especially as a drinking water source.

The natural solution to this problem is to be found in enhancing the oxygen levels in such lake. For this purpose special, laser-cut hoses are engineered to flow at the top of the anaerobic mud located at the bottom of the lake. With a relatively small compressor assisted with ozone for automatic self-cleaning from inside the diffusing hoses, even a very large and very sick lakes can be restored to full aerobic health in just about ten weeks. In addition, the hoses slowly eat through the already accumulated organic waste at the rate of approximately 6" (15 cm) per year until the bottom is clear. The system also hinders any new accumulation of waste.

As a result of the remediation, marine life is restored, and the water becomes very clean and suitable for recreational purposes. Dissolved organic content may also drop from the typical 5 to 20 mg/L down to below 1 mg/L. Logically, if the lake is used to supply drinking water, the treatment station downstream requires much less ozone to finish the purification process and sanitize the water flow completely from all viruses, bacteria, mould and parasites.

Though this technology has been around for many decades it is not yet well known for the simple fact that it is too inexpensive and thus not as attractive to lake remediation equipment suppliers. In the present budget restricting situation most communities cannot afford the large expense of treating their bad lake water. It is much easier to clean the lake first, and use the intensive ozone treatment to complete the sanitation process.
