Pasig River Rehabilitation Commission
On January 1999 through
Executive Orders 54 and
65
the
Pasig
River
Rehabilitation Commission
was created.
PRRC Chairperson
Sec. Jose L. Atienza, Jr.
“Upgrade the water quality of
Pasig River to Class C level.”
What is Class C water quality?
•
•
CLASS C
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.
Waters for fishery
•
Secondary recreation like
boating
•
Water supply for
manufacturing processes after
treatment
•
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 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
In addition to these, the PRRC Project Management Office
identified additional programs to be included in the rehabilitation
of Pasig River. These are:
Target 10:
Establishment of water transport service
Target 11:
Bioremediation / Aeration and Filtration
Target 12:
Phytoremediation
Targets 1, 2, 4 and 5
Eliminate offensive odor;
reduce BOD; increase and
control flow of water and
reduce flooding

PILOT BIOREMEDIATION PROJECT
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, nonpathogenic and naturally-occurring microbial
isolates were used to attack, degrade and
neutralize the pollutants present in the river water.
