Protect Our Blanco – Blanco Water Reclamation Task Force

On March 8, 2022, the Blanco City Council voted to approve the Task Force recommendations and direct staff to negotiate a new TLAP permit with phased adoption of no discharge, with reference to the Protect Our Blanco sample guidelines.

Blanco Water Reclamation Task Force Recommendation, 2/28/2022
Protect Our Blanco Letter with Attachments, 3/1/2022

The Blanco Water Reclamation Task force worked from September 2020 to October 2021 to identify alternatives to wastewater discharges into the Blanco River.  Through fundraising and outside support, a third-party engineering firm was hired to assess costs to increase capacity for the Blanco wastewater system.  The final recommendation and engineering reports are as follows:

About the Task Force

In its Sept. 22, 2020 meeting, the Blanco City Council approved the creation of a Blanco Water Reclamation Task Force made up of four representatives for the City of Blanco and four members named by Protect Our Blanco facilitated through a MOU with the Meadows Center for Water and the Environment.  Working together, this effort aims to identify and investigate alternatives to direct discharge that will allow the City of Blanco to grow while protecting water quality, water supplies, and habitat.

Many thanks to the Task Force Members:

    • Connie Barron (City of Blanco Council Member)
    • Deda Devine (City of Blanco Council Member)
    • David Baker (WVWA & POB Board)
    • John Ransom (POB Board and downstream resident)
    • Gabriel Gregerman (Real Ale Brewing Co.)
    • Nick Dornak (Meadows Center facilitator)


The task force proposal envisioned a collaboration that recognizes the fundamental need to keep discharge out of the river, while recognizing the City’s interest in bringing more business to Blanco and helping the region’s population grow responsibly. Engineers can provide long-term solutions through jointly developed scenarios and calculations that span from conventional centralized to a variety of decentralized options. In particular, One Water systems handle wastewater as a resource, not a nuisance, which can be routed to reuse and other beneficial purposes that not only eliminate discharge, but also drastically reduce potable water demand.

For a city government with millions in debt obligations and perhaps tens of millions ahead, according to an engineering study, the task force offers further support to improve cost controls and tie revenue streams to capital outlays. Decentralized options promise more manageable scaling of capacity without discharge. Moreover, Hays County has committed to support the City of Blanco to preserve natural resources for its citizens downstream.

Beginning in October 2018, the City allowed treated effluent discharge to flow directly into the Blanco River. By the spring of 2019, the Blanco River had become filled with algae blooms downstream. Nutrient levels including nitrogen and phosphorus were too high to support a healthy river and prevent eutrophication and algae. When wastewater discharge into the Blanco River ended in December 2019, the river’s natural healing process returned the water to a cleaner, clearer appearance.

Protect Our Blanco continued its theme to be “good neighbors finding a peaceful balance,” working with the City as stewards of the river and our aquifers. Water’s impact permeates the Blanco’s limestone basin, through faults, fractures, and caves into the groundwater system, whose wells provide the sole source of drinking water for much of the Hill Country. Groundwater declines show that alternative water supplies are in desperate need, and beneficial reuse of treated wastewater could augment that supply and protect our aquifers.

The WVWA is partners with Protect Our Blanco and are working with the City of Blanco to incorporate One Water practices and explore alternatives to direct discharge of treated wastewater, including land application and beneficial reuse, and to serve as a model for other Hill Country communities as they grow.

Recent discharge history

Blanco started discharging in November 2018 at a daily average of 0.119mgd, and stopped in November 2019 at a daily average of 0.108 mgd. The highest daily maximum flow measurement was 0.513 mgd in May 2019.
