TASK B.6
Installation Report for Passive Nitrogen Reduction System
B-HS7
November 2013
Task B of the Florida Onsite Nitrogen Reduction Strategies Study (FOSNRS) includes performing field
experiments to critically evaluate the performance of nitrogen removal technologies that were identified
and pilot tested in FOSNRS Task A. To meet this objective, full scale treatment systems will be
installed at various residential sites in Florida, operated on septic tank effluent under actual onsite
conditions, and monitored over an extended timeframe. The Task B Quality Assurance Project Plan
(Task B.5) documents the objectives, monitoring framework, sample frequency and duration, and
analytical methods to be used at the home sites. This report documents the installation of a passive
nitrogen reduction system at a home site in Marion County, Florida (B-HS7).
System Overview
The B-HS7 passive nitrogen reduction system (PNRS) was installed in Marion County, Florida in
November 2013. It consists of adding a 300 gallon concrete pump tank, low-pressure distribution
network, and a lined Stage 1 and 2 drainfield. The existing 900 gallon dual chamber septic tank will
continue to provide primary treatment for the new PNRS system. Figure 1 is a plan view showing the
system components and layout of the installation. The complete as-built system drawings are included
in Appendix A.
Household wastewater enters the 1st chamber of the primary tank and exits the second chamber as
septic tank effluent through an effluent screen. Screened effluent is directed to the pump tank which
contains the pump and float switches. Pump tank contents are discharged through a low-pressure
distribution network installed inside Infiltrator EQ36-LPTM chambers. The low-pressure distribution
network consists of a central manifold design with (4) 33-foot long, 1.25-inch diameter perforated
laterals. The perforations are 0.25-inch in diameter and spaced 3-feet off-center. Below the infiltrators,
24-inches of native soil was installed. Below the native soil, 12-inches of lignocellulosic media was
installed above a 30 mil PVC liner with a 6-inch lip around the outer perimeter. Therefore,
approximately 6-inches of the lignocellulosic media is saturated promoting denitrification of the nitrified
effluent. The treated effluent is discharged into the soil around the perimeter of the liner. A flow
schematic of the system is shown in Figure 2.

Installation
Installation of the system commenced November 13, 2013 and was completed on November 18, 2013. As previously discussed, the existing 900 gallon septic tank will continue to provide primary treatment. An access riser was installed above the second chamber of the primary tank (Figure 3) to allow for ease in maintenance of the existing outlet effluent screen. A two-way valve (Bull RunTM) (Figure 4) was installed following the septic tank outlet to allow the flow to either be completely directed to the new passive system (to the pump tank) or to the existing drainfield. A riser pipe was installed to grade over the valve, so that the valve can be turned after installation is complete. The valve is turned with a wrench on a rod which is long enough to reach within the riser installed.

The 300 gallon concrete pump tank was installed downgradient of the primary tank (Figure 5). The standard outlet pipe connection was plugged since the pump discharge pipe was installed through the riser. A Liberty LE51A-2 submersible pump was installed (Figure 6). One wide-angle piggyback float switch attached to the pump controls the effluent level in the pump tank. The height of the float is adjustable to calibrate a target dose volume. An additional float switch is connected to an audible/visual alarm (Figure 7) installed next to the power meter box to alarm for a high water level in the pump tank (pump failure). One inline flowmeter was installed following the pump discharge (Figure 8) with a bypass for maintenance/cleaning of the flowmeter.

The new treatment drainfield area was prepared for the 30 mil PVC liner installation (Figure 9). The liner was installed with a 6 inch lip around the outside perimeter. Above the liner, approximately a ½-inch sand layer (Figure 9) was installed to protect the liner during construction. Above the liner a 12-inch layer of lignocellulosic media, a blended urban waste wood from Wood Resource Recovery, Ocala, FL, was installed (Figure 9). Monitoring equipment surrounding the liner lip and inside the lignocellulosic media were installed (Figure 10). The various types of monitoring equipment installed

O:\44237-000-TPA\44237-001
include: stainless steel drivepoints, stainless steel suction lysimeters and ceramic cup suction lysimeters (Figure 11). To separate the top of the lignocellulosic media and bottom of the native sand layer a plastic mesh screen (1/16-inch) was installed above the lignocellulosic media (Figure 10). Following placement of the plastic mesh screen, a 24-inch native sand layer was installed (Figure 12). Ceramic cup suction lysimeters were installed above the mesh screen to represent water quality just after downward passage through the sand layer.

The 2”D pipe downstream of the flowmeter is reduced to 1.5”D in the center manifold of the low pressure distribution network (Figure 13). The manifold is connected to 4 laterals of perforated pipe (Figure 13) which distribute septic tank effluent over native sand inside Infiltrator EQ36-LPTM low profile chambers. The laterals were installed using pressure dosing pipe supports, so that a wet pressure test could be conducted (Figure 14) prior to installing the chambers over the laterals. Following the wet pressure test, the Infiltrator EQ36-LPTM low profile chambers were installed (Figure 15). Above the chambers, 12-inches of native sand cover (Figure 16) was installed to support wheel loads of 16,000 lbs per axle per the manufacturer. This will allow the homeowner to continue to operate a small tractor in the area. Hay and grass seed mix was placed above the sand (Figure 17).

Estimated Cost The final construction cost for the installed system was $13,836.66 as detailed in Appendix B.
System Start-up
The system was started up November 19, 2013, when all flow was diverted to the new passive system.
Preliminary sampling will begin in December to monitor nitrification.
