Note for New Business Customers
The water bill for a business is directly related to the meter's water budget and entitlement level. Exceeding the water budget will result in water billed at higher tier rates. Businesses—especially those that use large amounts of water such restaurants, coffee shops, laundromats, etc.—should ensure the meter’s existing water budget/entitlement is adequate for the intended end use. Please contact the MMWD Engineering Department at 415-945-1530 for more information and to determine if the existing entitlement is adequate for the intended end use for the site.
