Englishton Park Youth Rehabilitation Center ,Lexington, Indiana
10,000 gpd Package Wastewater Treatment System (PWTS)
Municipal expansion planned to 50,000 gpd (2010)


The facility was forced to close due to the onsite septic system failing and could not reopen without a new wastewater system. The owner needed to proceed immediately or risked losing the facility's contract operator.

Additionally, the nearby town of Lexington, Indiana was served by individual septic systems, many of which were failing. The town wanted to design for future expansion of the system wh

ere the town would install sanitary sewers to transport their wastewater to Englishton Park for treatment and disposal.

The project consisted of the installation of a 10,000 gallon per day package wastewater treatment system, flow splitter for future expansion, precast concrete disinfection building ultraviolet (UV) disinfection unit sized for future flow capacity, flow monitoring, gravity discharge to nearby stream under NPDES permit, and electronic monitoring using a digital microprocessor control panel with modem capability.

The Indiana Department of Environmental Management performed a complete plant audit in 2008 and the facility was awarded a Superior grade, one of the few ever awarded by the state for a small package plant facility.

Queens Grant Condominiums, Topsail Beach, North Carolina
40,000 
gpd Package Wastewater Treatment System (PWTS)

The Queens Grant Condominium Association had an old extended aeration activated sludge package wastewater plant that was in bad shape and needed extensive repairs. The owner of some of properties served by the plant also wanted to add additional units to the system, so it was decided to pursue building a new facility.

The EnviroFilter package wastewater treatment system was chosen due to the excellent effluent quality and the fact the system could be buried below grade to 

minimize the visual effect on the oceanfront development.

Due to the small disposal area, denitrification was required to reduce the size of the surface drip disposal field to fit within the existing site plan.

The system consisted of a lift station to route the wastewater from the existing gravity sewers to the new plant, two 15,000 gallon fiberglass primary treatment (septic) tanks, one 20,000 gallon combination fiberglass primary treatment (septic) tank and duplex pump station, a 40,000 gpd EnviroFilter package wastewater treatment system consisting of four 40,000 gallon fiberglass tanks, three 35,000 gallon fiberglass holding tanks with an integral duplex pump station, a package upflow filter denitrification system, a package dosing pump station for distribution of the treated effluent, surface drip irrigation disposal fields, an auxiliary power generator, a building to house the electrical panels, controls and denitrification system, fencing and site work, and removal and disposal of the existing steel package plant system.
 
The system was started up in 2008 and has met the regulatory discharge permit limits of < 10 mg/l BOD, < 10 mg/l TSS, < 125 count/100 ml E Coli, and < 4 mg/l Total Nitrogen.

Maple Leaf Farms, Inc., Milford, Indiana
10,000 gpd Package Wastewater Treatment System (PWTS)

Maple Leaf Farms operated a large duck processing facility in northern Indiana that disposed of its domestic and process wastewater in aerated lagoons. The Indiana Department of Environmental Management required the company to separate the domestic wastewater from the process wastewater or provide better treatment of both. The company decided to separate the wastewater streams and to treat the domestic wastewater separately using onsite disposal.

Due to the size and land requirements of a conventional onsite wastewater system, and the soils in the area, it was decided to install an EnviroFilter package wastewater treatment system for pretreatment prior to soil disposal. Use of the EnviroFilter system would significantly reduce the size and co

st of the required mound disposal system.

The project was completed in 2007 and consisted of separating the domestic and process wastewater within the gravity sewer collection system, installation of a 10,000 gallon fiberglass primary treatment (septic) tank to increase capacity of the existing system, a 10,000 gpd EnviroFilter fiber

glass tank package recirculating media filter, and a mound disposal field.

After installation of the system, the company added approximately 150 additional employees to increase production. The additional employees and infiltration/inflow in the existing gravity collection system has caused influent flows into the system to exceed 20,000 gpd. The EnviroFilter system has consistently met the regulatory effluent requirements of 30 mg/l BOD and 30 mg/l TSS even while treating over twice the peak system design flow. The company is in the planning phase to increase capacity of the system by adding an additional 20,000 gallon primary treatment tank, another 10,000 gpd EnviroFilter unit, and another mound disposal field.

 
Town of Laconia, Laconia, Indiana

11,650 gpd Package Wastewater Treatment System (PWTS)

The Town of Laconia located in southern Indiana had a problem with failed septic systems and lots too small to install replacements. The Town wanted to pursue installation of a conventional sewer system and treatment plant, but the town was too small to cover the operation and maintenance expenses of such a system.

The consulting engineer for the town discovered the EnviroFilter package wastewater treatment system which was designed to reduce operation and maintenance expense. The town was awarded grants in order to build the system and by using the EnviroFilter system was able to pursue a community based wastewater system.

The project consisted of installation of new primary treatment (septic) tanks at each lot, installation of individual or shared precast concrete tank EnviroFilter units throughout the community, a pressure sewer collection network, a UV disinfection system, and force main to the Ohio River for surface water discharge.

The system was installed and began operation in 2002 and has been continuously meeting its NPDES discharge limits of 20 mg/l BOD, 30 mg/l TSS, 4 mg/l Ammonia, and 125 count/100 ml E Coli.

Golfview Subdivision, Cedar Lake, Indiana

20,800 gpd Package Wastewater Treatment System (PWTS)
 
The developer of Golfview Subdivision in northern Indiana was investigating wastewater disposal options when the state health department informed him of the EnviroFilter package wastewater system. He evaluated the EnviroFilter system and found it would minimize his initial capital costs compared to a conventional collection system and treatment plant.

The developer decided to use the EnviroFilter package wastewater treatment units at individual and shared lots and collect and dispose of the treated effluent using a community disposal field.

Individual septic tanks and residential EnviroFilter units in precast concrete tanks were installed at designated locations in the subdivision as the residences on those lots were constructed. The treated effluent is discharged by the EnviroFilter treated effluent dosing pump into a PVC pipe collection network. The collection system transports the treated effluent to a community subsurface drip irrigation disposal field on property within the development. The collection system and drip field was completed in 2000 and EnviroFilter installations have been completed as homes were constructed.

The EnviroFilter wastewater system has met the effluent requirements of the Indiana State Department of Health since system startup in 2000.
