What's included in water line installation

  • Pressure testing and disinfection per the governing water district's standards
  • Coordination with the applicable water purveyor on design and acceptance

Water purveyors in the Las Vegas Valley

Which agency serves your property depends on its location. The Las Vegas Valley Water District serves the City of Las Vegas and much of unincorporated Clark County, while the City of Henderson and City of North Las Vegas each operate their own water utility within city limits. Design standards, meter requirements, and review timelines can differ between these agencies — see our permitting overview for more detail.

Sequencing with other utilities

Water lines are typically installed with required vertical and horizontal separation from sanitary sewer lines to prevent cross-contamination, and are often installed after sewer but alongside or before storm drain, depending on the site's civil design. Getting this sequencing right is one reason many owners hire a single contractor for combined utility packages — see our full site development page.

When you need a water line contractor

  • You're developing a new parcel that needs a domestic or fire water service
  • An existing service needs to be upsized for a larger building or fire flow requirement
  • Your commercial site plan requires new fire hydrants or a looped water system
  • An existing water line is failing and needs replacement

Frequently asked questions

Which agency provides water service in the Las Vegas Valley?

It depends on location. The Las Vegas Valley Water District serves the City of Las Vegas and much of unincorporated Clark County, while the City of Henderson and City of North Las Vegas each operate their own water utility within their city limits.

What's the difference between a domestic water line and a fire service line?

A domestic water line supplies drinking and general-use water to a property, while a fire service line supplies water specifically for fire suppression systems and hydrants. Many commercial projects require both, sized and installed separately.

Does a new water line need to be tested before it's put into service?

Yes. New water mains and services typically require pressure testing and disinfection to the applicable water district's standards before the line is approved for use.

Is backflow prevention required on a new water service?

Backflow prevention is commonly required, particularly for commercial and irrigation services, to protect the public water system from contamination. Requirements vary by water purveyor and use type.

Is there a cost to use Vegas Utilities to find a water line contractor?

No. Vegas Utilities is free for property owners and developers. We're paid a referral fee by our contractor partners when a project we refer results in signed work.
