3116 Antelope Ridge Trail, Parker CO

This is an NDDS system in Elkorn Ranch, in Parker, CO.  The home is a walkout 3 bedroom and therefor a small 1,000 gallon poly septic tank, a 500 gallon poly pump tank (both made by Infiltrators), which pumped to 4 valves serving a 4000 square foot field. We have to stair step the field 3 times as the min depth was 12″ and the max was 30″ to acheive proper percolation and evaporation.

We began, as we normally do, by trying to find the stubbed plumbers pipe.  Some plummbers do a fantastic job of labeling and others do not.  Fortunately, the homeowner/GC was with us to help locate it.  Notice the depth of this by the height of the cleanout!

 

We then excavated for the 1000 gallon poly tank followed by the 500 gallon pump tank. Notice the risers must come to grade (or above). We also installed the floats and alarm.

 

We then treched 20, 8″ wide, 100′ long lines.  Min Depth 12″ and Max depth 30″.  We had to have 4 separate stairs to acheive flatness.

 

The system was connected to the valves. (covered with boxes)

 

Here is another view. It’s hard to see but there are 4 steps.

 

We passed inspection from Elbert County and Colorado Geoscience, and we covered and off to the next.  Another successful OWTS instalation from:
