An official from the Davao River Basin Management Alliance said there is an urgency to implement Vertical Helophyte Filtering Systems (VHFS) to rescue the ailing Davao River. Dr. Della Grace Bacaltos, representing the Help Davao Network, bared this during a media interview held on November 23, 2023, at Bapa Benny Tutud of Ateneo de Davao University (AdDU). She underscored the need to expand VHFS deployment along the Davao River owing to elevated levels of phosphate, suspended solids, and fecal coliform.
