ILOILO CITY: Most local government units in Western Visayas do not know the importance of rainwater catchment and harvesting, and some are even biased against the simple technology and took for granted the storing of rainwater intended for use during the summer months. This was bared by former Environment Secretary Elisea Bebet Gozun who is currently the USAID Be Secure Climate Resiliency Team Leader and Jessica Salas, a board director of the Metro Iloilo Water District, during an El Nino forum held on Thursday and Friday in this city. Gozun said an existing national law enacted in 1989 requires barangays to have rainwater catchment and harvesting facility to help mitigate the impact of the dry season. But local government units (LGUs) took for granted the provisions of the law and considers rainwater harvesting a low priority. Meanwhile, Salas said there is a need for a new and stronger law to compel LGUs to establish rainwater catchments in their respective barangays, schools, barangay health stations, other government facilities and even homes.
