No Dumping Sewage

Hill Country creeks are some of the purest and lowest nutrient water bodies in Texas. In certain areas, water from the land and creeks makes its way into the Edwards Aquifer. This aquifer recharges quickly and is extremely sensitive to water pollution. The same polluted water from land or creek will return to natural springs and people’s wells.

Wastewater effluent (the product from a wastewater treatment plant) has undergone some treatment, but is not treated to drinking water standards and is not nearly clean enough to be dumped safely into our creeks. This effluent water contains high levels of nutrients (nitrogen and phosphorous) which cause algae blooms. These algae blooms are not only unsightly but through decomposition take up oxygen in the waterbody. The waterway may become hypoxic, causing fish and other aquatic life to perish. Algae also restricts light moving into the lower portions of the creek, altering habitat. These effects can reduce biodiversity even when a creek is not completely devoid of oxygen. At high levels, nitrogen is unsafe in drinking water, restricting transport of oxygen in the blood. This is especially dangerous for babies and young livestock. [1] Additionally, effluent water contains metals, pharmaceuticals, and many other chemicals from cleaning and body care products.[2] The full effects of these products are not yet known.

Of course! Land application and beneficial reuse are two large scale alternatives to direct discharge of wastewater effluent available with the state permitting agency, the Texas Environmental Commission on Environmental Quality (TCEQ), (TCEQ) are land application and beneficial reuse. In addition, there are other small scale alternatives including septic systems and newer decentralized technologies. Land application simply means spraying wastewater effluent over a dedicated irrigation field and allowing soil and plants to treat the effluent  while beneficial reuse uses effluent for landscaping, such as medians. For small scale alternatives, developments can use septic systems and newer decentralized technologies.

Currently, it is illegal by state law to directly discharge sewage into creeks in the Barton Springs Edwards Aquifer recharge zone. However, it is not illegal at the headwaters of these creeks that flow into the recharge zone (contributing zone.) Even so, to date, there have been no direct discharges in the contributing zone but the Long Branch permit proposes to do so, by dumping into the tributary of Barton Creek. 

Save Barton Creek Association, Protect Our Water, Barton Springs Edwards Aquifer Conservation District, Hays Trinity Groundwater Conservation District, and several landowners have entered into a settlement agreement over Dripping Springs’ direct discharge wastewater permit.

As a result of the efforts of SBCA and the other protestants, Dripping Springs has agreed not to dump sewage into Onion Creek for the immediate future and create a Utility Commission that will help them meet their goals of wastewater re-use. A permit will still be issued but, if Dripping Springs stands by their commitments and the community continues to be engaged we are hopeful we can prevent the pollution associated with discharge.
