Natural ecosystems have been used for wastewater treatment for centuries. Natural Treatment Systems (NTS) -- capture, retain, and treat storm water, converting this “nuisance” into a valuable source of water. These natural systems remove a wide variety of contaminants, including nutrients, pathogens, and micro-constituents. Its a long proven treatment for water reclamation.
Natural systems for treatment of wastewater have always been attractive as a cost effective alternative to the costly expense of developing storm drains and sewers. Natural treatment systems require a modest level investment and low maintenance and operation costs. NTS are an environmentally sound alternative to storm drains and sewers which, when overwhelmed during periods of heavy rain, result in damage to our valuable ecosystems.
The natural treatment systems are modeled after the successful system of natural treatment ponds which remove nitrogen, phosphorus and bacteria from surface waters entering the local water sources.
Man-made wetlands use natural ecosystems to remove sediment, nutrients, pathogens and other contaminants from dry weather runoff and prevent these contaminants from reaching vital water sources and the ocean. NTS wetlands also provide additional neighborhood open space and wildlife habitat.
NTS provides an environmentally sound way to address the pollution caused by urban runoff. Urban runoff is any water that flows into storm drains when there are no storms. Polluted urban runoff flows to the ocean year-round due largely to inefficient watering of landscaping, hosing down of sidewalks and driveways, and washing of cars. This water carries trash, fertilizers and other contaminants with it, polluting our local streams and the ocean.
Natural treatment systems are very efficient treatment technologies for purification of many types of wastewater, sludge handling and use of purified water for irrigation. Natural treatment systems are quite often underestimated in their treatment performance by water authorities and it is not uncommon that the water authorities are reluctant to permit the use of these systems.
Natural technologies of wastewater treatment focuses on the use of natural technologies of wastewater treatment, including, among others, constructed treatment wetland, soil filters, waste stabilization ponds, aquatic plants systems, irrigation by pre-treated wastewater. These natural technologies of wastewater treatment are environmentally friendly ways of treatment and management of particular types of wastewater.
The natural technologies of wastewater treatment use natural, commonly occurring self-treatment processes that take place in the soil, water and wetland environment. The vegetation is directly involved in the treatment process, especially by the formation of favorable conditions for the development of microorganisms involved in the treatment process, and simultaneous utilization of released plant nutrients for the biomass production.
