Commercial and High Strength Zero Discharge Wastewater Systems and Wastewater Treatment Plants
A commercial wastewater treatment plant system, onsite sewage facility (OSSF), or commercial wastewater system, covers pretty much everything that is not residential. This includes schools, hotels, conference centers, convenience stores, vet clinics, motels, apartments, factories, manufacturing facility areas, wineries, breweries, restaurants, distilleries, conference centers, RV parks, marinas, and more.
We design, permit, construct, and operate systems up to 500,000 gpd in the State of Texas.
The permit requirements are vastly different, under the Texas Administrative Code, for such systems.
These are generally known as " high BOD " systems, or high strength wastewater, meaning the sewage strength is much higher than the amounts from a residence (10 times higher, and more). Such systems require not only hydraulic load balancing and disposal, but also proper biological load balancing and treatment. This is often accomplished by flow equalization of the system. Put our licensed professional engineer's knowledge to work for you to ensure your system will meet all present and future needs of your business, and operate without any problems in the future.
Currently, any system over 5,000 gpd requires a State issued permit. We can design and permit these systems, either for zero-discharge, or discharge systems.
Commercial Septic System
Generally, a commercial wastewater system is anyting that is either high strength sewage, or over 5,000 gallons per day. If over 5,000 gpd, this requires a lengthy permit process, and specialized civil engineering knowledge and licensure.
Our designs, done by a Registered Professional Engineer, can be either local permit level, or state permit level through Texas Commission on Environmental Quality ( TCEQ ). This can be a discharge permit, or a non-discharge permit.
This includes apartments, breweries, wineries, hospitals, medical office buidlings, strip centers, retirement homes, banks, convenience stores, car washes, hotels, RV pakrs, motels, restaurants, office buildings, retreat centers, retreat camps, and any system that does not have central sewer availability.
One of the other major factors in commercial systems is the sewage strength. This is known as high BOD strength sewage. Put another way, if it is higher strength than a home (over 300 mg/L BOD), then you need to use different design criteria. Ground disposal systems that utilize the soil for treatment must not have BOD strengths above 140 mg/liter before being sent to the disposal field. Commercial systems are designed to a minimum standard of 1200 BOD mg/L, and the increased use of low-flow fixtures and waterless fixtures (such as waterless urinals) are increasing the sewage strength to the system, under one permit criteria, and if over 5,000 gpd, have other permit criteria, including metal reduction, ammonia requirements and nitrate requirements.
For systems below 5,000 gpd, if off-the-shelf aerobic treatment units ( ATU ) are used, you must hire a Registered Professional Engineer to do this design, as the units were tested only with residential class sewage.
As part of our design process, we analyze what you, the client, need to accomplish. We design each of our system to be able to expand, as your business grows. This saves signficant costs on the front-end, allowing you to spend less on critical infrastructure, yet ensuring you will not have to go through expensive and time-consuming retrofits in the future. We offer valuable assitance in site selection, so you do not have to purchase a larger tract than you absolutely need, either. We offer growth projections, as well as system projections, to ensure a properly designed system that is "just right" for your current needs.
