Temporary construction meters (TCM) are for water use on construction projects.
Download and fill out the TCM application. A company tax ID is required.
Visit IRWD’s main lobby at 15600 Sand Canyon Avenue, Irvine, before 4:30 p.m. We are open during regular business hours and closed on alternating Fridays and holidays.
After processing, take your application to the Customer Service counter across the lobby to open your account and schedule meter installation. This takes one business day, so plan accordingly. Note: Hydrant construction meters using domestic water require a backflow device. Meters cannot be transferred to other companies or developers.
Below is a summary of information necessary for each type of TCM application.

Cross Connection Control Policy Handbook
No. TCM applications must be hand-delivered with a deposit check to the Development Services counter at IRWD’s Sand Canyon office during business hours.
If you have a red hydrant, you will need to submit a letter of authorization from the owner along with your temporary meter application before we can set the meter. You will likely still need a backflow for the meter.
If you have a purple hydrant, this means the water is recycled water, and you do not need a backflow prevention device or letter of authorization to use it. TCM rates for recycled water are lower than domestic water.
We can place or move a TCM as soon as the next business day.
Yes, and the name on the check must match the name on the application.
No. IRWD no longer provides customer-movable (floating) meters. Once meters are placed, they can only be moved to new hydrants by IRWD staff, free of charge.
To have your TCM moved to a new location, call Customer Service at 949-453-5300 and inform them of your request. You will not need to apply for a new meter, but you will need to recertify your backflow device.
