How it works
The first 10 cu.m of consumption is a flat minimum charge — ₱144.20 (Maynilad) or ₱128.46 (Manila Water) — regardless of whether you used 1 cu.m or 9. From 11 cu.m upward, each additional cubic meter is charged at a bracketed rate that rises with consumption (tiers at 11–20, 21–40, 41–80, and 81+).
On top of the basic charge, the bill adds FCDA (reviewed quarterly — can be positive or negative), a 20% environmental charge, a 20% (Maynilad) or 25% (Manila Water) sewer charge if your meter is connected to a sewer line, a ₱1.50 maintenance service charge, and 12% VAT on the subtotal.

Frequently asked questions
Which concessionaire serves my address?
Maynilad covers the West Zone — Manila, Caloocan, Las Piñas, Malabon, Muntinlupa, Navotas, Parañaque, Pasay, Valenzuela, plus parts of Cavite and Quezon City. Manila Water covers the East Zone — Mandaluyong, Marikina, Pasig, Pateros, San Juan, Taguig, plus parts of Quezon City, Manila, Antipolo, and Rizal. If you're on a boundary, your meter card or any recent bill will say which one you're billed by.
Why does my bill change month-to-month even when consumption is similar?
The FCDA (Foreign Currency Differential Adjustment) is reviewed quarterly by the MWSS Regulatory Office and can flip between positive and negative depending on the peso's movement against the dollar. As of May 2026 it's slightly negative for Maynilad (around −1.2%) and slightly positive for Manila Water (around +1.8%). Both are small but enough to move the total by ₱20–₱60 in a typical household bill.
What counts as 'sewer service connected'?
If your residence is connected to either concessionaire's sewer line — usually true for newer subdivisions and high-rises within the franchise area — you pay a sewer charge of 20% (Maynilad) or 25% (Manila Water) of the basic charge. Households on septic tanks without sewer hookup don't pay it. Check the line items on your last bill: 'Sewer charge' should appear with a peso amount if it's billed.
How does the bracket structure work?
The first 10 cu.m of consumption is a flat minimum charge — ₱144.20 (Maynilad) or ₱128.46 (Manila Water) — regardless of whether you used 1 cu.m or 9. From 11 cu.m upward, each additional cubic meter is charged at a tier rate: ~₱28.79 (Maynilad) or ~₱25.66 (Manila Water) per cu.m for the 11–20 tier, then roughly double that for 21–40, and so on. A typical 30 cu.m household pulls a basic charge of around ₱900–₱1,000.
How can I lower my bill?
The bracketed structure means the marginal cost rises as you climb tiers, so trimming from the top down moves the needle fastest: fix leaks (a dripping faucet alone can be 5–10 cu.m/month), shorten shower time, and run washing machines and dishwashers only at full load. Greywater reuse for plants and floor washing can clip 2–4 cu.m for households that bother with it. Above 80 cu.m the marginal rate roughly triples — at that tier, even small cuts matter a lot.
