New Business Process

New Business Application Requirements

New applicants must submit a New Business Application (updated April 2024) to a Project Coordinator (PC). Appointments are encouraged because PC’s may have other appointments or field work. Walk-in appointments may be required to wait for a PC to become available. The PC assigned to an applicant’s project will be the applicant’s point of contact and is responsible for facilitating their application. Submittal requirements for each type of service installation are listed on page three of the application, together with the initial engineering submittal review fees.

Water Utility Designs

Water Utility designs (W-1’s) on TMWA Drawing templates are required as part of the submittal package. Once all the necessary items are submitted; water rights, engineering and right-of-way begin the review process simultaneously on the applicant’s project. Partial submittals will be returned.

Engineering & Water Resource

The Engineering and Water Resource review is a multi-level process. The extent of review by each is dependent on the type of service requested.

Applicant’s water rights may need to be dedicated. Associated costs may include, but are not limited to:

  • Purchase of water rights
  • Water  Resource Sustainability Fund
  • Will-serve documentation preparation fees

The initial water utility design will be reviewed, with red-lines being returned to an applicant’s engineer for revision.

After the revisions are completed and subsequently re-reviewed, the project’s approved water utility design drawings will be approved by TMWA Engineering and a Water Service Agreement (WSA) will be issued to the applicant.  In some cases Nevada Administrative Code (NAC) Compliance will be submitted to the Health Authority for review and approval. Once subsequently approved by TMWA Engineering a WSA will be issued.

Once the WSA is executed, addresses provided, fees paid and water rights and right-of-way satisfied, a pre-construction meeting may be scheduled.

Schedule Your Meeting

Pre-construction meetings are required for all projects. An applicant’s assigned TMWA PC will schedule, facilitate and conduct the pre-construction meeting. Attendees should include the applicant, the applicant's engineer, a Nevada State Contractors Board licensed contractor (General A or A-19),  the TMWA PC, Inspector, Engineer, and Backflow Administrator.

Construction & Inspection

Applicants must contact TMWA’s PC 48 hours prior to commencement of the water facility construction and provide the work order number (WO #) to schedule a TMWA inspector during the on-site construction of the water facilities.

  • Final inspection to ensure completion of punch list items
  • Locks out water meter setters
  • Accepts facilities
  • Upon completion of project, TMWA inspector will return as-builts to the PC

When backflow is required please call 775-834-8288. If you have deferred your Water System Facility (WSF) charges as part of a subdivision, contact your PC to make lot payments and initiate meter sets.
