DEWS project is the continuation of HYDROMET Project which aims to deploy 500 units of hydrometeorological stations (Automated Rain Gauges (ARG) and Water Level Monitoring Stations (WLMS)) and warning stations in minor river basins all over the country.

A total of 33 hydromet stations are to be installed to PAGASA-validated sites in CALABARZON Region - 13 ARG and 20 WLMS. Data from these sensors are viewable at

HYDROMET Project is a roll-out project led by the Advanced Science and Technology Institute (ASTI) which deployed 1,000 hydrometeorological sensors all over the country and was implemented in 2013-2014. The project was also one of the components of DOST's Nationwide Assessment of Hazards (NOAH) Project.

The DOST Regional Offices were tasked to deploy the hydromet stations to 18 major river basins and selected minor rivers systems.

For CALABARZON, a total of 54 hydromet stations were installed - 36 Automated Rain Gauges (ARG), 17 Water Level Monitoring Stations (WLMS) and one TANDEM (ARG+WLMS). Data from these sensors are viewable at

Hazard Notification, Dissemination and Awareness (HaNDA) is an ICT-enabled Disaster Risk Reduction and Management (DRRM) system used in the dissemination disaster-related updates, gathering field reports during occurrence of disasters, monitoring of data from ASTI-developed hydromet sensors and warning/alarming of LGUs. HaNDA also stores CALABARZON Region hazard maps, vulnerability ratings and DRRM-related information.
