  1. 1. DENR Administrative Order No. 34 Water Usage and Classification Water Quality Criteria
  2. 2. Water Usage and Classification• The quality of Philippine waters shall be maintained in a safe and satisfactory condition according to their best usages .
  3. 3. Fresh Surface WatersClassification Beneficial UseClass AA Public Water Supply Class I. This class is intended primarily for waters having watersheds which are uninhabited and otherwise protected and which require only approved disinfection in order to meet the National Standards for Drinking Water (NSDW) of the PhilippinesClass A Public Water Supply Class II. Public Water Supply Class II. For sources of water supply that will require complete treatment in order to meet the NSDW.Class B Recreational Water Class I. For primary contact recreation such as bathing swimming, skin diving.
  4. 4. Fresh Surface WatersClassification Beneficial UseClass C •Fishery Water for the propagation and growth of fish and other aquatic resources; •Recreational Water Class II (Boating, etc.) •Industrial Water Supply Class I (For manufacturing processes after treatment).Class D •For agriculture, irrigation, livestock, watering, etc. •Industrial Water Supply Class II (e.g. cooling, etc.) •Other inland waters, by their quality, belong to this classification
  5. 5. Coastal and Marine WatersClassificatio Beneficial Use nClass SA •Waters suitable for the propagation, survival and harvesting of shellfish for commercial purposes; •Tourist zones and national marine parks and reserves established under Presidential Proclamation No. 1801Class SB •Recreational Water Class I •Fishery Water Class IClass SC •Recreational Water Class II •Fishery Water Class II •Marshy and/or mangrove areas declared as fish and wildlife sanctuariesClass SD •Industrial Water Supply Class II •Other coastal and marine waters, by their quality, belong to this classification
