Pasig River Rehabilitation Commission
On January 1999 through Executive Orders 54 and 65 the Pasig River Rehabilitation Commission was created.
“Upgrade the water quality of Pasig River to Class C level.”
PRRC Chairperson Sec. Jose L. Atienza, Jr.
• Class AA• Waters intended as public water supply
requiring only approved disinfection to meet the Philippine National Standards for Drinking Water (PNSDW)
• Class A• Waters suitable as water supply
requiring conventional treatment to meet PNSDW
• Class B• Waters intended for primary contact
recreation like bathing, swimming and skin diving
• Class D• Waters intended for agriculture,
irrigation, livestock watering, etc.
CLASS C
•Waters for fishery
•Secondary recreation like
boating
•Water supply for
manufacturing processes after
treatment
What is Class C water quality?
Target 1: Eliminate offensive odor
Target 2: Reduce BOD load from 330 tons/day to 200 tons/day
Target 3: Reduce solid waste
Target 4: Increase and control the flow of water
Target 5: Reduce flooding
Target 6: Enforce Zoning Ordinances by respective LGU’s
Target 7: Remove sunken vessels
Target 8: Develop linear parks
Target 9: Relocate informal settlers
Rehabilitation Programs for Pasig River
Based on the Final Report of the 1990 Feasibility Study conducted by the Department of Environment and Natural Resources (DENR) and the Danish International Development Assistance (DANIDA) the following targets were identified to improve the water quality and environmental condition of Pasig River:
Target 10: Establishment of water transport service
Target 11: Bioremediation / Aeration and Filtration
Target 12: Phytoremediation
Rehabilitation Programs for Pasig River
In addition to these, the PRRC Project Management Office identified additional programs to be included in the rehabilitation of Pasig River. These are:
Targets 1, 2, 4 and 5
Eliminate offensive odor; reduce BOD; increase and control flow of water and
reduce flooding

Pilot Site : Brgy. Napindan, Taguig City
Site Description : The pilot site is an 800 m X 1.1 m parapet wall with domestic wastewater coming from 79 households in the area.
Bioremediation : Twenty three (23) carefully selected, useful, non-pathogenic and naturally-occurring microbial isolates were used to attack, degrade andneutralize the pollutants present in the river water.
