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.

Page 9: Pasig River Rehabilitation

• 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?

Page 10: Pasig River Rehabilitation

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:

Page 11: Pasig River Rehabilitation

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:

Page 12: Pasig River Rehabilitation

Targets 1, 2, 4 and 5

Eliminate offensive odor; reduce BOD; increase and control flow of water and

reduce flooding

Pilot Bioremediation Project

Pasig River Rehabilitation CommissionPILOT 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, non-pathogenic and naturally-occurring microbial isolates were used to attack, degrade andneutralize the pollutants present in the river water.
