DOST-Funded Technology to help keep Siargao water safe


Safe water may be the next attraction in Siargao as the island puts on board the eco-friendly Septic Tank System or Eco-sep. This technology consists of a septic water management system that addresses the problem of untreated wastewater in resorts, public establishments and households. Launched in Siargao last September, the Eco-sep technology is installed in three pilot sites, namely General Luna Market, General Luna High School and Traveler’s Beach Resort. “Samples collected from these sites will serve as a baseline for the DoST [Department of Science and Technology] to encourage resort owners, LGUs [local government units]and households to adopt the technology in our campaign [as part of the project],” according to engineer Noel Ajoc, project coordinator. Dr. Merlinda Palencia, developer of the Eco-sep technology, explained that the Eco-sep system deployed in the pilot sites contains Vigormin, an organomineral that hastens the decomposition of harmful bacteria that lodge in septic tanks. Vigormin prevents bacteria from escaping from the tank, thus avoiding contamination of wastewater in sewage systems. Palencia noted that the Eco-sep system will be very efficient in Siargao. Most septic tanks on the island have a bottomless design, which allows wastewater to quickly seep through the ground. This poses higher risk of contamination in freshwater and seawater.
