City of Napa water rates vary by customer class, as detailed below.  Most customers are billed bimonthly.  Billing units are 1,000 gallons.  Rates are higher for customers outside the City limits.  Customers in certain high-elevation zones pay an additional surcharge to cover pumping costs.  Low-income single-family residential customers may be eligible for the RateShare Discount Program.

Water rates generate the revenue needed to operate the water system and invest in necessary upgrades.  The City Council established the most recent rate schedules in 2011, with annual rate changes taking effect upon each customer's first billing period that began on or after October 1.  The current rates, listed in the 10/1/15 column below, remain in effect until further notice.  For more details on the current rates and why they were adopted, visit the Water Rate News page from 2011.  [Previous water rates from 2004 to 2011 were uniform quantity rates subject to an annual inflation-based adjustment.]

Meter Reading 

meter.jpgCity service workers read your meter periodically to determine usage.  From/To service dates listed on your bill show the time period covered by your billed usage.  Being able to read your own meter is a great way to track your consumption, check for leaks, and help you conserve.  In most cases, your water meter is located close to the street just behind the curb in the front of your building.  It is in a ground level concrete box and has a concrete lid.  You can remove this lid by inserting a large screwdriver in the hole in the lid and lifting carefully.

To read a typical City water meter, simply read across the numbers in the box.  The current reading for this sample meter is just over 4076234 gallons.  (Because the far right number in the box is fixed at zero, the ones place is read using the dial pointer.)  If the reading you had taken earlier was 4062113 you would have used 14,121 gallons.  Since the City bills in 1,000 gallon units, this bill would be for 14 units.  The triangle-shaped spinner indicates water movement and is useful for checking leaks.
