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)

Waters for fishery

•

• •

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.

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 Pasig River Rehabilitation Commission 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.
