THIS WAS A NDDS PROJECT IN WHICH WE WERE HIRED TO BAIL OUT A CONTRACTOR THAT WASN’T CAPABLE OF COMPLETING A NDDS SYSTEM. THE TANK WAS TO BE MOVED DOWN THE HILL TO AVOID THE EXPENSE OF A DEEP TANK. THE 6000 SQUARE FIELD WAS FED BY A 1250 GALLON ROTH TREATMENT TANK AND A 1000 GALLON ROTH PUMP TANK.
Design of system: Colorado Geoscience
Aggregate Supplier: N/A
Plastic Supplier: Castle Pines Winwater
Tank Supplier: Roth
We crushed the deep tank (no shown) and then had to run mainline pipe around 80′. We had to double case approx 20′ due to being under the customer’s drive-way.
We then dug the hole for the 2 tanks. Pretty darn deep. Each tank will have 4′ of risers.
We trenched the 30 lines @ 100′ each. It’s important the trenches be 2′ apart, on center. (6000 square feet) There are also several steps down, as each system must be level.
We installed the 6 ball valves. These are 2 inch ball valves that must remain level for the system to function property and last.
View from the bottom of the hill.
Here is another shot of the valves. Notice the snifter valve, which is to be installed at the high-point of the system, to release air in the feeder pipe.
Here is a shot of both tanks with the effluent line heading up the hill to the NDDS field. Very deep tanks for today’s standards. (4′) Lots of work but meaningful. This client was a doctor for the US Army. …another successful wastewater project completed by:
