Should local utility bills include surcharges to fund reclaimed water infrastructure projects?

Residents in Travis Heights saw the start of a major reclaimed water infrastructure project earlier in 2026. This initiative by Austin Water connects northern and southern sections of the city's system to increase capacity for non-potable uses.

Why it matters

Expanding the reclaimed water system reduces the demand for treated drinking water from Highland Lakes, providing a more resilient supply during dry cycles. This infrastructure investment serves to offset the city's growing water needs as the local population increases.

Austin Water customers utilized 1.8 billion gallons of reclaimed water in 2025, a significant increase from the 1.2 billion gallons used a decade prior. Lake Travis currently sits at 94.8% capacity, though the long-term impact of this infrastructure on drought resilience is still evolving.

The players

Austin Water

The city-owned utility department responsible for providing drinking water and managing reclaimed water infrastructure.

The details

The project adds 4,500 feet of reclaimed pipe to move treated wastewater for irrigation, cooling, and toilet flushing. Funded through water rates and a 15-cent surcharge per 1,000 gallons, the infrastructure expansion represents part of a $110 million total investment through 2025. Construction in the Travis Heights area is expected to span 21 months total.

Timeline

  1. 2015: Reclaimed water usage reached 1.2 billion gallons.

  2. 2025: Annual reclaimed water usage increased to 1.8 billion gallons.

  3. Earlier in 2026: The Travis Heights pipe installation project began.

  4. July 2026: Lake Travis reached capacity.

The Texas Context

This project continues the city's $110 million investment strategy for reclaimed water infrastructure established to secure long-term utility resilience. It reflects a wider trend among central Texas municipalities to decouple irrigation and industrial needs from the Highland Lakes drinking supply.

Residents may notice construction activity in Travis Heights throughout the 21-month project duration. Homeowners also have the option to support these city-wide sustainability efforts through a $6 monthly voluntary contribution on their water bills.

The takeaway

The city is continuing to shift non-potable demand toward recycled water to preserve our shared drinking supply. Watch for traffic impacts in the Travis Heights neighborhood as the 21-month installation period continues through next year.
