Your Philippine water bill is calculated using a tiered (block) rate system — the more you use, the higher the rate per cubic meter. Manila Water and Maynilad each have their own rate schedules approved by the Metropolitan Waterworks and Sewerage System (MWSS). On top of the water charge, both add sewage fees (typically 50–70% of the water charge) plus environmental charges and a CERA surcharge tied to the peso-dollar exchange rate.
Use this calculator to estimate your total bill. Select your water utility and enter your monthly consumption in cubic meters (m³) — check your water meter or last bill for this figure.

East Zone vs West Zone: Which Are You In?
Metro Manila is divided into two water concession zones. Manila Water serves the East Zone: Quezon City (east portion), Marikina, Pasig, Pateros, Taguig, Muntinlupa, San Juan, Mandaluyong, and parts of Rizal province. Maynilad serves the West Zone: Manila City, Caloocan, Malabon, Navotas, Valenzuela, Parañaque, Las Piñas, Makati (west), and Cavite portions.
If you're not sure which zone you're in, check our Water District Finder — it identifies your concessionaire and local water district by city or municipality.
Frequently Asked Questions
How is the water bill calculated in the Philippines?
Philippine water bills use a tiered (block) rate system. The first 10 m³ per month is billed at the lowest rate, and each higher block is charged progressively more per m³. Manila Water and Maynilad also add sewage, environmental, and CERA (Currency Exchange Rate Adjustment) charges on top of the base water charge.
What is the average water bill in Metro Manila?
A typical household using 15–20 m³ per month pays roughly ₱350–₱650 with Manila Water or ₱450–₱750 with Maynilad including all surcharges. Bills jump significantly above 30 m³ due to higher tiered rates — and very high bills often indicate a hidden leak rather than actual household use.
What is the difference between Manila Water and Maynilad?
Manila Water serves the East Zone of Metro Manila (Quezon City east, Marikina, Pasig, Taguig, Muntinlupa, and parts of Rizal). Maynilad serves the West Zone (Manila City, Caloocan, Malabon, Navotas, Valenzuela, Parañaque, Las Piñas, and parts of Makati and Cavite). Both are MWSS concessionaires but operate independently with separate rate schedules.
What is CERA on a Philippine water bill?
CERA stands for Currency Exchange Rate Adjustment. It's a surcharge that compensates the concessionaire for fluctuations in the peso-dollar exchange rate, because significant portions of the original concession investment and debt are denominated in USD. When the peso weakens, CERA goes up; when it strengthens, CERA decreases.
How can I reduce my water bill in the Philippines?
Fix dripping faucets (a slow drip wastes 15–20 liters/day and adds 0.5 m³/month). Install low-flow showerheads — they cut bathroom usage by 40%. Collect rainwater for garden use. Check for hidden leaks by turning off all taps, waiting 15 minutes, then checking if your meter has moved. Even small leaks can add 5–10 m³ per month.
How do I dispute a high water bill in the Philippines?
Contact your water utility's customer service within 15 days of receiving the bill. Request a meter re-read and bring documentation of your recent usage. If a leak is found on your side of the meter, you may still be liable, but some utilities offer first-occurrence leak adjustment programs. File with the MWSS if your complaint is unresolved after 30 days.
