Construction Standards for On-Site Wastewater Treatment
Chapter 285
June 2001

Onsite regulations were revised June 13, 2001. There are no plans for further revision prior to July 31, 2002.

Those technologies approved for onsite wastewater treatment and disposal include:
· Standard treatment-Septic tanks and intermittent sand filters;
· Proprietary treatment-All proprietary treatment must be tested by NSF Standard 40 (aerobic, sand filters other than standard design, and wetlands);
· Non-standard treatment-Recirculating sand filters, trickling filters, rotating biological contactors;
· Standard disposal-Pipe and gravel. Media that can be used: tire chips and steel slag;
· Proprietary disposal-Leaching chamber, drip irrigation, EZ Flow, multi-pipe, and gravelless pipe;
· Nonstandard disposal-Low-pressure distribution, surface application (spray system), mounds, and soil substitution.
For circumstances allowing technologies not listed above see Section 285.32(c) of the State Code.

Surface discharge is an option for Texas, and no NPDES permit is required. However, surface discharge is limited to spray application only in conjunction with any treatment device that produces disinfected, secondary quality effluent. Application rates vary across the state, and maintenance contracts are required to ensure that the treatment device is operating properly and that effluent is properly disinfected.

State Code allows for drainfield area/size reductions based on the testing protocol, i.e., criteria and parameters for which the technology was tested.

Funding exists to assist homeowners either replacing failing systems or installing new ones, but it is not through the Texas Natural Resource Conservation Commission, and it is difficult to get. Questions may be directed to Graber or Samuelson (above).

Mr. Graber or Mr. Samuelson may be contacted for information about ongoing onsite wastewater demonstration, research, or testing projects in Texas.

State Code requires management programs for any surface application system and for any system that has been permitted to maintain secondary quality effluent. Local entities have the authority to require more stringent requirements than state rules, but they must be based on a greater environmental protection.

The number of permits issued per year is tracked; local entities, such as health departments or health districts, report the number of permits issued to the TNRCC. The numbers for new construction and system repair and replacement are not maintained as separate categories, but are combined.

Texas Code defines a failed system as one that creates a nuisance or is in violation of the permit/rules. Improper or no soil identification and the wrong type system installed are cited as the most common reasons for system failure.

The state has a licensing/certification program for onsite wastewater professionals. In Texas, site evaluators and P.E.'s are licensed/certified to perform site evaluations/inspections.

 

Quick Facts:
Return to Index

Total number of onsite systems: 1990 U.S. census reports 1.27 million.

Number of new systems installed each year: 45,000.

Failure definition: Hydraulic failure (surfacing effluent) or inadequate treatment resulting in
contamination of surface- or groundwater.

Number or proportion of systems presently failing: 10-15% estimated.

Number or proportion repaired annually: NA

Number or proportion replaced annually: NA

Number or proportion of repairs or replacements that require alternative technology (e.g.,
sand filters, pressure dosing):
Efforts are underway to collect this sort of information, but at
present it is not systematically available. In east Texas, marked by tight clayey soils, 20-30% of
new systems are reported to be alternative; the percentage could be higher for replacement
systems.

Number or proportion of repairs or replacements that require advanced technology (e.g.,
disinfection, nutrient removal):
Again, systematic information is NA, but aerobic systems and
spray irrigation systems with disinfection are reported to be commonly used in some areas.

Cost of a conventional septic system installation: $1200-$4000, range $1000-$24,000.
