The Evolution of the OSSF (On-Site Sewage Facility) Program in Texas,
from Primordial Soup to an 800 Pound Gorilla

   How and why the program began
   Its history as a dysfunctional, unwanted child
   The current TCEQ (Texas Commission on Environmental Quality) structure of OSSF rules
      and enforcement; Relationship between TCEQ and Travis County rules
   Who’s really in charge and why
   The distinction between prescriptive and performance regulations
   The (under-estimated) role that the septic system plays
      in property purchase and development/site planning
   Should TCEQ regulations be adhered to?

How the Size, Type and Cost of the Septic System is Determined

   TCEQ setback requirements as limiting factors (will the water level in the
      well rise a couple of inches every time the owner flushes the commode?)
   What is a ‘site evaluator,’ compared to a ‘designer,’ and what is their role
      in planning of a septic system?
   How are septic systems SIZED in Texas? The water quality treatment line:
      from nuclear wastes to perfectly pure water (no such thing)
   Residential – the variance quality and maintenance levels from
      which a homeowner can choose

Day Two, Wednesday, July 29, 2020
8:30 - 11:30 am CDT (including a 15-min. break)

Types of Septic Systems Approved in Texas and Used, Especially

   Universal components of any septic system – from raw sewage to
      environmentally helpful moisture
   Passive vs. Active, Primary treatment vs. Secondary systems
   Standard systems – gravel, leaching chambers and gravel-less
   Aerobic Treatment Units – general structure, how they work,
      their advantages and disadvantages
   Spray application described; advantages and disadvantages
   Drip irrigation described; advantages and disadvantages
   New gray water rules and how to apply them
   Nutrient reductions

Commercial – the Shocking Cost,
Footprint and Long Term Maintenance Requirements

   The technical differences between residential and commercial septic systems
   The two key factors in any commercial septic system that someone must specify
      and through which they will assume the liability for its proper functioning
   A step-by-step, unpublished method of ENSURING that the final system will work properly
   Metrics of a finely designed system and the chemical, physical
      and hydraulic measurements that must be recorded
