How to Size a Wastewater Storage Reservoir for a Texas Reuse Project

The storage reservoir on a Texas reuse project is not a nice-to-have. It is what keeps the facility in compliance during the months when the reuse site cannot accept all the effluent being produced. Size it wrong and the permit will not be approved. Size it right and the facility operates without a compliance gap through any seasonal condition the site will experience.

Permit-by-Rule vs. Standard Permit: When Each Path Applies to Your Development

Before you engage a water and wastewater engineer for a Texas development project, it helps to understand which permitting pathway your project likely falls into. The difference between a permit-by-rule and a standard TCEQ permit is not a minor procedural distinction, it determines your timeline, your regulatory obligations, and in some cases whether construction can start before TCEQ issues any formal authorization at all.

Land Application Permits for Treated Wastewater: A Texas Developer’s Guide

The Texas Commission on Environmental Quality (TCEQ) requires every regulated water and wastewater facility to demonstrate that essential systems will continue to operate during an electrical outage. This requirement is not just a formality; without backup power, a distribution system can lose pressure in a matter of minutes, disinfection can stop, and wastewater lift stations can overflow. Any of these conditions can create a direct public health hazard and, at the same time, put the utility in violation of its permit.

Texas Wastewater Permitting Guide For Developer

Texas wastewater permitting requires developers to obtain TCEQ approval before constructing or operating wastewater treatment facilities. The process involves three main permit types: TPDES (surface water discharge), TLAP (land application), and Chapter 210 (reclaimed water reuse).
