THIS IS AN NDDS SYSTEM IN HUDSON CO, IN WELD COUNTY. THE HOME IS A 3 BEDROOM AND THEREFOR A 1,000 GALLON POLY SEPTIC TANK, A 500 GALLON POLY PUMP TANK (BOTH MADE BY INFILTRATORS), WHICH PUMPED TO 4 VALVES SERVING A 6400 SQUARE FOOT FIELD. INSTALLED AT 24″ WITH MINIMUM DEPTH 12″ AND THE MAX WAS 30″ TO ACHEIVE PROPER PERCOLATION AND EVAPORATION.
Design of system: Homestake Engineering
Aggregate Supplier: NA
Plastic Supplier: Plastics Inc.

We began with locating the knockout in the foundation wall, that was left by the mudman, Effran. We glued the cleanout and capped to 6″ above grade.
Here is a pic of the 1000 gallon tank out of the ground. It’s about 11′ long by 5′ tall and 5′ wide.
Here is a shot of the tanks set in the ground. Notice the electric wire that are actually buried under the main line and being pulled back so we can backfill around the 1st tank. The tanks need to be level!
Here is a shot of the 500 gallon pump tank with the SJE Rhombus doing control box/alarm combo. This pump tank houses the 1/2 horse power Liberty Pump; which pumps the effluent water to the field. The pump sits on that paver that happens to be in the background.
So here is the 2″ supply line from the pump tank the to valve nest area.
Here is the valve nest area. This is meant to distribute an even amount of effluent to the 4 fields, so it MUST BE LEVEL! Notice a plumbers valve in before the valves. This valve shall be placed at the high-point from the pump to the valve area.
Here is a pic of the 1st 2 zones of drip irrigation field. This field has 4 systems – each having 8 lines that are 100′ long. They also must be 2′ apart and not be deeper than 30″ or shallower than 12″. It’s important that the headers are installed level, and the laterals (lines) shall remain level too.
Another shot of the drip field. Laterals must be 2″ wide, or greater.
Here are zones 3 and 4. We have ‘bedded’ the lines in preparation for inspection from Weld County and the Designing Engineer.
