Boil Water Has Been Lifted

Boil Water Rescind Notice
May 23, 2017

On May 22, 2017, the Texas Commission on Environmental Quality (TCEQ) required our public water system, Nueces Water Supply Corporation, PWS ID 1780052, to issue a Boil Water Notice (BWN) to inform our customers that due to reduced distribution system pressure, water from our system must be boiled prior to consumption. 

Our system has taken the necessary corrective actions to restore adequate pressure, and bacteriological samples have returned showing no coliform found.  We have provided TCEQ with testing results that indicate that the water no longer requires boiling as of May 23, 2017.   

If you have questions, contact General Manager Carola G. Serrato at (361) 592-1720.

If a customer wishes to reach TCEQ, they may call 512-239-4691.
