What are the benefits of submetering an apartment community?

When residents pay for what they actually use, they cut back. Most properties see 15 to 30 percent lower water use. Submetering also catches leaks early, lets you bill common-area usage accurately, and can raise the value of the property. Payback usually lands within 12 to 18 months.

Is submetering legal in Texas?

Yes. In Texas, apartment water and wastewater submetering is regulated by the Public Utility Commission of Texas (PUCT) under 16 Texas Administrative Code Chapter 24. Those rules were previously handled by the TCEQ under 30 TAC Chapter 291. Electricity submetering also falls under PUCT rules. NES tracks every requirement so your property stays compliant.

Who regulates submetering in Bexar County?

Water and sewer submetering falls under the Public Utility Commission of Texas (PUCT), in 16 TAC Chapter 24, Subchapter I. Utility service itself in Bexar County falls under the PUCT. NES tracks the current Texas and local requirements for your address, so billing is set up to match the rule.

Who provides water and utilities in Bexar County?

Water and sewer service across most of Bexar County is provided by the San Antonio Water System (SAWS). NES works with whichever provider serves your property, installs the submeters, reads them, pays the master-meter bill, and bills your residents in-house across the San Antonio area.

How much does it cost, and what is the ROI?

Most submetering installs pay for themselves within 12 to 18 months through the utility cost you recover. We'll run the numbers on your actual master-meter bills and unit count, then send you a clear, no-obligation estimate.

Will I be locked into NES equipment?

No. NES installs nonproprietary meters that other companies can read, and extended warranties are available on our submeters. You're never locked in.
