When is the Commercial Meter Sizing Form used?

The water permit group reviews water meters and water services on building permits for the City and uses the Commercial Meter Sizing Form to begin our building permit review.

The Commercial Meter Sizing Form is used to determine what size the water meter needs to be. You must fill out a Commercial Meter Sizing Form if you're:

• building a new commercial structure
• building a new mixed-use building (complete the Commercial Meter Sizing Form only for the commercial portion of the structure)
• doing a commercial alteration
• making tenant improvements to an existing building
• applying for a Public Works permit
• making a voluntary meter request for non-residential use

Information on how to fill out and submit the Commercial Meter Sizing Form is below. A missing or incomplete Commercial Meter Sizing Form will delay the review process.

A separate Commercial Meter Sizing Form is required for each meter.

Information needed for the Commercial Meter Sizing Form

If you have an existing meter, it may be serving multiple tenant spaces, various floors, and separate structures. You will need to know how many fixtures and the types of fixtures the existing meter is serving. You will also need to know the number of fixtures and what kind of fixtures the meter will serve after construction.

If you need a new meter because there is no existing meter or you want an additional meter, you will need to know how many fixtures and what kind of fixtures the new meter will serve.

Steps for completing Commercial Meter Sizing Form

1. If the existing meter will be retained, enter the number of each fixture by type the meter currently serves in the first column (Existing Fixture Qty). If there is not an existing meter, go to step 2.
2. Enter the proposed number of new fixtures by type in the second column (Proposed Fixture Qty).
3. Add existing and proposed fixture quantities together and enter into the third column (Existing and Proposed Fixture Total).
4. Multiply each fixture's total quantity by that fixture's multiplier in the fourth column and enter the result into the fifth column (Fixture Units). 
5. Add all fixture units for the Total Fixture Units (TFUs) below the fifth column.
6. Use the TFU's value to find the meter size on the reference chart at bottom of the form.
