Mombasa Water Supply and Sanitation Company, known as MOWASSCO, supplies water and sewerage across Mombasa. Paying your bill no longer means a queue at their offices, you pay from M-PESA with a Pay Bill. The account field is the account number on your bill.

The verified paybill

MOWASSCO uses paybill 565444. The account is your MOWASSCO account number, printed on your water bill. It is not your meter serial number and not your phone number.

Pay your bill step by step

  1. Open the M-PESA app, or dial *334#.
  2. Select Lipa na M-PESA, then Pay Bill.
  3. Business number: 565444.
  4. Account: your MOWASSCO account number from the bill. No spaces or hyphens.
  5. Enter the amount.
  6. Enter your M-PESA PIN and confirm.

Keep the M-PESA SMS. The payment usually reflects on your MOWASSCO account within a few minutes to a few hours, utility posting is not always instant.

Work out the bill first

If you are not sure how much you owe, remember a water bill is not flat: it is the units used across rising tariff bands, plus a sewerage charge where you are connected, plus a fixed charge. Our water bill calculator does the sum from your meter reading, so you pay the right amount rather than guessing.

Payment not reflecting
