| (a) Sufficiency of service. Each retail public utility
shall plan, furnish, operate, and maintain collection, treatment,
and disposal facilities to collect, treat and dispose of waterborne
human waste and waste from domestic activities such as washing, bathing,
and food preparation. These facilities must be of sufficient size
to meet TCEQ's minimum design criteria for wastewater facilities for
all normal demands for service and provide a reasonable reserve for
emergencies. Unless specifically authorized in a written service agreement,
a retail public utility is not required to receive, treat and dispose
of waste with high biological oxygen demand (BOD) or total suspended
solids (TSS) characteristics that cannot be reasonably processed,
or storm water, run-off water, food or food scraps not previously
processed by a grinder or similar garbage disposal unit, grease or
oils, except as incidental waste in the process or wash water used
in or resulting from food preparation by sewer utility customers engaged
in the preparation and/or processing of food for domestic consumption
or sale to the public. Grease and oils from grease traps or other
grease and/or oil storage containers shall not be placed in the wastewater
system.
(b) Sufficiency of treatment. Each retail public utility
shall maintain and operate treatment facilities of adequate size and
properly equipped to treat sewage and discharge the effluent at the
quality required by the laws and regulations of the State of Texas.
(c) Maintenance of facilities.
(1) The retail public utility shall maintain its collection
system and appurtenances to minimize blockages.
(2) If the utility retains ownership of receiving tanks
located on the customer's property or other facilities and appurtenances,
it is the utility's responsibility and liability to perform routine
maintenance and repair.
