Baltimore Water Bill Planning Calculator
This calculator uses the current July 1, 2026 small-meter planning figures from DPW’s rate sheet. It is not an official bill and does not include every possible adjustment, penalty, lien, account-specific item or meter-size change.
Formula: account management $5.79 + water infrastructure $17.52 + sewer infrastructure $16.51 + water $4.86/Ccf + sewer $14.37/Ccf + stormwater entered + Bay Restoration $5.00 + past/other entered.
Common Baltimore Water Bill Line Items Explained
Infrastructure charges
Fixed water and sewer infrastructure charges can appear every month based on meter size. They are separate from consumption.
Consumption charges
Water and sewer volumetric charges are based on Ccf usage. A toilet leak can raise both water and sewer charges quickly.
Stormwater
Stormwater charge is tied to stormwater management, not water used inside the house.
Bay Restoration Fee
The DPW rate sheet customer-bill example shows a $5.00 Bay Restoration Fee line.
Penalty
Delinquent metered charges can receive a 1.64% penalty under the city code, unless the account is protected by Water4All enrollment rules.
Estimated / unusual bill
Use the portal usage details and billing history before assuming the bill is wrong. Gather proof before filing a dispute.
