The PPCWD is grateful to USAID Safe Water as it turns over the completed Hydrologic Reports for the 6 major rivers in Puerto Princesa; Babuyan, Bacungan, Inagawan, Irawan, Langogan, and Montible.

The hydrologic reports contain the surface water and groundwater information of each river source, including its basin information, historical discharge, flow analysis, projection of future flows under different climate scenarios, field validation, and potential groundwater recharge areas.

This information is vital in the operation of PPCWD as it provides data on the availability of supply in the potential water sources in the city.
