Ecosystem have design and build more than 400 Water Reclamation Facilities (WRF) using the most efficient & powerful biotechnology process since 1995. The Ecosystem Sequence Bio Reactor technology is proprietary and unique. Unlike all other technologies, it does not produce hazardous, explosive and rotten egg smelly Hydrogen Sulfide gases. This technology was specifically developed for sewage treatment plants to be located underground and beneath the lowest level of the basement for high rise & high density buildings when space is a problem. In 1997,this technology was applied for use in a sewage treatment plant located in the lowest basement level 2 of the most luxurious Cebu Condominium in the Philippines, the first of its kind in the world. Another salient feature is this is the most compact system in the high-end category for excellent quality of effluent compliant to the latest International Standard for Water Re-use.
