Cleanblu DEWATS rendering

DEWATS stands for Decentralized Wastewater Treatment Plants. Traditionally, in established regions wastewater is managed using a network of sewer systems, lift stations and large central treatment plants. A multitude of drawbacks exist to these largely obsolete systems that leads to contamination of the groundwater table as well as rivers, oceans and other natural water bodies. The economic burden of maintaining these traditional systems is huge and not sustainable for most municipalities. As a typical example in 2008, the State Department of Environmental Conservation reported that the city of New York's, system consisted of 6,000 miles of pipes, 135,000 sewer catch basins, 93 pump stations, and 14 massive sewage treatment plants. The majority of the city's sewer pipes, laid long before the federal government passed the 1972 Clean Water Act and mandated newer technologies, are part of what is called a "combined sewer system." Most of this system was in fact laid out 50 to 150 years ago, and there have been few major upgrades since then. It takes a staff of 6,000 and $2 billion a year just to maintain these antiquated systems.Several international studies have proven that the cost of DEWATS is significantly cheaper to implement and operate. Numbers range by country but are anywhere between three to ten times cheaper depending on existing sewer infrastructure. When used in combination with an existing sewer system, processed water is flushed into the sewer, which then acts as an underground irrigation system, leaching the clean water into the ground thus replenishing dwindling groundwater levels. In the case of new developments DEWATS eliminates the need to build a sewer infrastructure and treatment plants, saving billions of dollars, enormous amounts of energy and processing water and eliminating the vast amount of potential decontamination to waterbodies, soil and atmosphere.
