Dear Mayor Sparger:
The Texas Department of Health has participated in several studies
and reviewed many other studies involving the disposal of wastewater byaseptictankwithasoilabsorptionsystem. The septic tank sewagedisposalsystemwasoriginallydevelopedtoserveruralresidences. For
this purpose, the properly installed septic tank system performed well
and permitted rural residences to utilize water carried sewage disposal.
More recently, the population distribution has shifted from rural
to urban creating rapid development in the fringes of urban areas.
Quite often, lot sizes are no larger than those found in subdivisions
serviced by central. water and sewage systems. Unfortunately, in many
cases, subdivisions were located in areas with soil conditions unsuit-
able for septic tank systems.
Industry, in an effort to find solution to the problems of mal-
functioning soil absorption systems, has developed several types of
home wastewater treatment systems. Many of these systems will reduce
the pollutional character of the wastewater but the wastewater must
still be disposed of thru a soil absorption system. None of the home
treatment systems reduce the amount of wastewater which must be dis-
posed of. The failure of a septic tank system may be caused by a number
of circumstances including inadequate soil percolation, improper con-
struction, design, installation and misuse. The single most importantfactorconcerningpublichealthproblemsresultingfromthesefailures
is the residential dwelling density which is a function of lot size.

Platted subdivisions of single family residences served by a pub-lic water supply but utilizing individual subsurface absorption methods
for sewage disposal should provide for individual lots having surface
areas of at least 15000 square feet.
L trust this information will be helpful. Lf you have further
questions, feel free to call me.
Sincerely,
