NWRB Functions1. Policy Formulation and CoordinationFormulate policies and plans within theframework of Integrated Water ResourcesManagement (IWRM)Plans 2007 Philippine IWRM PlanFramework IWRM Plan in Pampanga RB(completed) Groundwater ManagementPlan in Water ConstraintCities (on-going) Comprehensive WaterResources Assessment ofMajor River Basins (ongoing)Policies Groundwater Allocation forMetro Manila andsurrounding areas Groundwater Allocation forMetro Cebu Granting of Water Rightsover Surface Water forHydropower Projectsrequiring more than 80%dependable flowAmendment to the 1976 Water Code ofthe Philippines (on-going)
NWRB Functions2. Resource Regulation- Conserves and protects all waterresources-Regulates water utilization andallocation based on policiesconsistent with beneficial use andsustainable development.- Regulation of water use throughthe water rights systemWaterFor LivelihoodWaterAs a Resource
NWRB Functions3. Economic Regulation Protects consumers and safeguardthe economic viability of waterutilities by: determining service standardsand targets tariff levels and schemes monitoring and measuringcompany performance enforcing compliance imposing sanctions Authorize the operation of privatewater service providers by grantingCertificate of Public Convenience(CPC)Viability ofUtilityConsumersLocal Government SystemsRural Water AssociationsCooperativesPrivate Sector UtilitiesBulk Water SuppliersWater Peddlers

Water Resources Management : Issues and ChallengesWater Quality and Quantity Unabated extraction ofgroundwater due to rapidurbanization andindustrializationInadequate Sewerage andSanitation facilitiesWatershed degradationDeteriorating health of riverand coastal systemsIndiscriminate land usedevelopment
Water Resources Management: Issues and ChallengesExtreme Events:Increasing incidence andintensity of water relatedrisks such as Typhoons,Floods, Droughts andLandslides.
Water Resources Management: Issues and Challenges Increasing waterdemand togetherwith insufficientwater infrastructurethreatens tooutstripsustainable levelsof supply
Water Resources Management: Issues and ChallengesGroundwater ContaminationLeaching of industrial,agrochemicals and animalwastes in agro-industrial areasSub-surface dischargesfrom latrines and septicsystems and infiltration ofpolluted urban run-off
Water Resources Management: ChallengesSurface Water PollutionDirect dumping of domesticsolid waste in rivers andlakes created adverseimpact on water quality andavailabilityWastewater dischargesfrom domestic andindustries to bodies ofwater contaminate waterbodies
Water Resources Management: Issues and ChallengesThreats of Climate Change Increased intensity and frequency ofstorm (La Niña) and droughtNiño)(El Variation in streamflow andgroundwater recharge affecting waterquality and seasonal wateravailabilitySeven extreme tropicalcyclone/southwest monsooninduced extreme events occurredin 1991 to late 2004 Higher temperatures affecting waterquality (such as eutrophication) Sea Level rise causing saltwaterintrusion into surface and groundwater, affecting the amount andquality of water suppliesThe worst drought occurred in1997-1998 El Niño, resulted insevere water shortage in M.Mla
Water Resources Management: Issues and Challenges Numerous and Conflicting laws andpolicies at the national and local levels Absence of updated and reliabledata/information to fully conduct a waterresources assessment (supply anddemand analysis, water balance, etc.)

Water Resources Management: Initiatives andOpportunities Presence of the Water Utilization Units (WRUs) -DENR toassist NWRB in terms of inventory of water users indifferent areas nationwide and other selected functionsrelated to water permit inspection and monitoring andassisting water permit applicants Established regional offices in Metro Cebu and MetroIloilo in 2018 Partnership with DOST PCIEERD (R and D projects) todevelop capabilities in increasing the resiliency of waterresources through proper management and planning forappropriate infrastructure as well as growing challengesand uncertainties brought upon by climate change
