The Department of Science and Technology (DOST) will embark on a pilot project that aims to sanitize, through natural biological techniques, the residential areas along the city's coasts. A Dutch scientist, who has worked with the agency as an intern, is proposing the use of marshland plants, or helophytes, to naturally filter waste water headed to the sea. The project will work alongside a cheap and profitable public toilet and laundry system.
