Texas lets owners bill residents for submetered or allocated water once the property meets the state's water-conservation preconditions, and owners must register with the PUCT before billing residents. NES installs the submeters, reads them daily, and bills your residents across Dallas County. Get a free bid.
NES handles water, gas & electric submetering for apartment communities, condominiums, and mobile home parks across Dallas County and the Dallas area. Install, meter reading, resident billing, and compliance, all handled in-house since 1968.
Dallas has more apartment units than any Texas county except Harris, and most of the garden communities built from the 1970s through the 2000s sit on a single Dallas Water Utilities master meter. Texas has the clearest submetering rules in the country: the owner registers with the PUCT before the first bill, every meter uses the same unit of measure, residents pay the property's actual rate, and the service charge stays inside the 9 percent cap. NES holds the PUCT registration for the properties it bills, reads the meters daily, and bills at the rate the property pays, whether that is Dallas Water Utilities or the Irving, Garland, Mesquite, or Richardson system.

Rules & compliance
Submetering rules & laws in Dallas County
Governing rule: 16 TAC Chapter 24 · PUCT
Texas state rules
Water and sewer submetering falls under the Public Utility Commission of Texas (PUCT), in 16 TAC Chapter 24, Subchapter I
Owners must register with the PUCT before billing residents for water and sewer; electric billing currently requires no PUCT registration, and gas billing requires none
Every submeter must be tested for accuracy before service, and all units must use the same unit of measure
PUCT rules set how charges are calculated and what each resident's bill has to show
RUBS (allocated) billing for water and electricity must use PUC approved formulas
Owners may add a surcharge of up to 9 percent on submetered water and sewer charges, and late fees are capped at 5 percent
No administrative fee is allowed on electric billing; on gas, an administrative fee of up to $3.00 is allowed on submetered gas only and must be disclosed in the lease
Water and wastewater submetering rules moved from the TCEQ (30 TAC Chapter 291) to the PUCT in 2014. Electricity submetering has its own PUCT rules.

Utility submetering puts a meter on each unit that measures and bills its water/sewer, gas, and electric use. The technology has been around since the early 1920s. NES installs the meters, reads them, pays the master-meter bill, and bills your residents, all in-house and with bilingual support.
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.
