When do I apply for a large water meter?
New and existing construction
Apply for a large water meter after you have received an approved Building Code Enforcement (BCE) utility plan and an approved OCE Plan and Profile provided by the Office of the City Engineer.
Commercial and multifamily developments located Outside the City Limits (OCL) will need an OCL plumbing and utility plan approval from Building Code Enforcement's Plumbing Inspections section.
When Taps & Meters approves your application, you will be given a Water New Service (WNS) number. The WNS number will be your identifier for your permit for any future updates. After Taps & Meters approves your large water meter application, Customer Account Services completes the request. Customer Account Services issues invoices for your large water meter permit and sets up new water accounts. If any accounts associated with your permit are not in good standing, you will not be able to purchase your permit until the account issues are resolved. Customer Account Services staff at the Houston Permitting Center may instruct you to call the Customer Account Services call center to resolve billing issues for existing accounts. The call center can be reached at 713.371.1400. We are unable to update existing accounts at the Houston Permitting Center.
Once you pay your invoice, your plumber will receive a work order within 10-15 business days from Customer Account Services to set up an inspection with the Inspections group. If you have not received an invoice or permit work order after receiving a WNS number you may contact Customer Account Service by email at [email protected]
