CURRENT SITUATION
Before clean up After clean up
• Estero water still does not meet quality standards
• Need to reduce the pollutant load reaching the
Estero, rather than treating the water within it

1. WASTEWATER TREATMENT PILOT
• Main Goal: Show the way to improve water quality.
• Capture and treat sewage flowing into the
Estero and grey water received by drainage
network (black and grey waters)
• Allow the water of the Estero flow into the
Pasig River, through flood gates operation.
• Improve the CSOs.
• Pilot easily replicable example.
• USD 60,000 and minimum O&M expenses

Proposed Site for the Wastewater
Management
SELECTED SITE: BARANGAY 672
• Objectives:
• show how intercepting and
treating discharges with a
low cost system can result
in good quality effluent
• prove its efficiency, and
feasibility for larger scale
replication
• 58 houses, 7 existing septic tanks
• Direct discharge to estero
• Population: ~496 people
• Est. water consumption ~30m3/d
• Average BOD est.: 127 mg/l

2. FLOOD GATE MANAGEMENT
Objective: to avoid water stagnancy
Flood gate operator:
Metro Manila Development Authority (MMDA)
Recommendation
• Flood gates should be opened if water level in
Estero de Paco is higher than in Pasig River.

3. INTERCEPTORS AND COMBINED SEWER
OVERFLOW MANAGEMENT
Operators: Maynilad / MMDA
Recommendations: Avoid overflowing in the CSO duringdays with no rain.
Inspect the CSO weekly, esp. afterstorms.
Clean the CSOs, avoid screensblocking.
Improve design to ensure easiermaintenance.
If overflowing is due to sewer pipe
clog, unclog immediately.

5. HEADWATERS
• Large outfall discharge in the headwater , between
Osmena Highway and the railroad.
• Two barangays are connected to this pipe
(discharge 370 m3
/d)• Manila Water will connect outfall to its network.

5. HEADWATERS
• Septic tank blocking the flowbetween Estero de Paco and
Estero Tripa de Gallina
• Septic tank will be removed
• Manila Water will connect
the outfall to its sewer
system by pumping.
• MWSS endorsed the plan.

6. SOLID WASTE MANAGEMENT
INITIAL ACTION PLAN
Operator: Manila LGU
• Solid waste management issues:
• Large quantities involved
• Small alleys not accessible to
collection trucks
• Inefficient waste collection,
transportation and disposal.
• Segregation will allow gettingrevenues from ‘valuables’:
• Organic matter, plastics, paper,
glass and metal.

6. SOLID WASTE MANAGEMENT PILOT
Improved collection system
• Containers for disposal,
collection and Recycling Points
• Collection schedule
• Transfer/Storage points
established for selected alleys.
• Routes for LGU’s garbage
trucks reviewed and discussed.

7. PACO MARKETStrategies for Wastewater and Solid Waste
Management Improvement
• Operator: Paco Market Admin
• Issues:
• Septic tank, which receiveswastewater from the fish section,
overflows to the estero
• Other discharges directed to the
drainage of the public market.
• Solid waste is not properly collected

Guidelines for maintenance:
• Inspected frequently, every three months.
• Check system :
• no overflowing,
• scum layer above 8 cm of scum baffle bottom
• sludge layer is below of 30 cm of the outlet.
• Ensure outlet pipe is not clogged.
• Remove sludge and scum build-up.
• Clear access to the septic tank.
• Connect the overflow to the sewerage system.
• Avoid solid waste entering system

REMOVAL OF ISLAND AERATORS
AND DREDGING OF ESTERO
• Issues
• Did not improve water quality
•Costly operation
• Created sludge
Need to dredge the estero
• Obstruction of water flow
Remove aerators to avoid
floods
