Re: Cattle Creek CommercialCenter, Building uQ", OWTS Z&A:197404.011
Dear Mr. White:
The permit issued from Garfield County for Building Q is for a minimum 1O00-gallon two compartment
septic tank from Building Q and 2,000-gallon septic tank with a pump in the second half of the of the
tank to dose the etfluent to a2,M8 sq fi Soil Treatment Area (STA)
This letter is to signify that the OWTS Cattle Creek Commercial Center Building Q has been
constructed in accordance with the intent of the design. Building Q was designed to have a 1000-
gallon two compartment tank and receive the effluent from Building Q, as the primary septic tank.
The treated and filtered etfluent water was then designed to flow into a second 1000-gallon septic
tank that is used as the pumped dosing tank for the Soil Treatment Area (STA). This dosing tank has
a 5O0-gallon settling detention tank and then onto the 5OO-gallon pumped dosing tank.
The contractor installed a two compartment 1,O00-gallon septic tank at Building Q. The contractor
then installed a second 1,00O-gallon two chamber.septic tank that is the pumped dosing tank.
This primary 1 ,O00-gallon two chamber septic tank is followed by a SO0-gallon chamber for additional
treatment. This provides for up to 1,500 gallons of detention prior to being delivered to the pumping
tank. The second half of the 1OO0-gallon tank will be used as "dose pumping tanK'to the STA. The
dose tank will fill up and then a pumped dose to the STA. This will allow the STA to dry-out between
cycles. The volume of the pumped doses can be controlled by mechanicalfloats in the dose tank.
The second 1,O0O-gallon septic tank has two inlet tees connected to the tank for application to the
leach field. One of the inlet connections is from Building Q 1,OO0-gallon septic tank, the other inlet
tee is installed for the future services later to the south of the Soil Treatment Area and is currently
capped.
The tank system was constructed to accommodate up to four bathrooms and other domestic uses
within Building Q. The STA was constructed to accommodate daily flows up to 1920 gallons per day
for the system. We believe the equipment that has been installed correctly per the intent of the
design and the dosing pumped system has been tested to pump the system effluent and will properly
dose the Soil Treatment Area.
Very truly yours,
