Lowndes County Interpretive Center
Lowndes County, Alabama
EnviroFilter™ 4,000 gpd
PRMF Wastewater Treatment System


The Lowndes County Interpretive Center located on Highway 80 in Alabama is a ten million dollar structure made possible through the collaborative efforts of the National Park Service, the Federal Highway Administration and the Alabama Department of Transportation.

This 12,235 square foot facility serves as a rest area, and visitor information and interpretive center. The historical site chosen for the Interpretive Center is located on U.S. Highway 80, about halfway between Selma and Montgomery in rural Lowndes County, and had no available wastewater services.

The project consisted of the installation of a 4,000 gallon per day EnviroFilter™ package wastewater treatment system, gravity distribution box, chambered trenches for gravity effluent subsurface discharge, and electronic monitoring using a digital microprocessor control panel with modem capability.

The package wastewater system included one 10,000 gallon single wall fiberglass reinforced plastic primary treatment (septic) tank and one 10,000 gallon EnviroFilter™ single wall fiberglass reinforced plastic tank with attached growth package recirculating media filter (PRMF) for treatment of domestic wastewater.

The treated effluent has met the AL Dept. of Health regulatory discharge permit limits of 30 mg/l BOD5 and 30 mg/l TSS since it was put into operation in 2006.


Crenshaw County Industrial Park
Luverne, Alabama
EnviroFilter™ 4,000 gpd
PRMF Wastewater Treatment System


Hyundai Motor America built a new automotive assembly facility in Montgomery, Alabama, causing a number of automotive parts suppliers to seek plant locations in neighboring towns. Luverne, Alabama, located approximately 50 miles south of Montgomery, was one such location, but the site lacked readily available sewer. The cost of extending sewer was cost prohibitive, so their engineering firm looked at other alternatives.

The project consisted of the installation of a 4,000 gallon per day EnviroFilter™ package wastewater treatment system, gravity distribution box, chambered trenches for gravity effluent subsurface discharge, and electronic monitoring using a digital microprocessor control panel with modem capability.

The package wastewater system included one 10,000 gallon single wall fiberglass reinforced plastic primary treatment (septic) tanks and one 10,000 gallon EnviroFilter™ single wall fiberglass reinforced plastic tank with attached growth package recirculating media filter (PRMF) for treatment of domestic wastewater.

The treated effluent has met the AL Dept. of Health regulatory discharge permit limits of 30 mg/l BOD5 and 30 mg/l TSS since it was put into operation in 2004.


Pintlala Water System, Inc
Hope Hull, Alabama
EnviroFilter™ 4,900 gpd
PRMF Wastewater Treatment System


The Pintlala Water System provided water service for a residential subdivision near Hope Hull, AL. The developer of the subdivision had installed a gravity sewer system and facultative lagoon with creek discharge for wastewater service to the subdivision.

Over time the gravity sewers began experiencing infiltration/inflow into the system and overloaded the lagoon. The lagoon was also not meeting its NPDES discharge limits for suspended solids and ammonia. The engineering firm for Pintlala Water needed a cost effective wastewater solution, but could not afford to abandon the lagoon and build a new wastewater plant.

The solution was to install a 4,900 gpd EnviroFilter™ package recirculating media filter wastewater treatment unit downstream of the lagoon to polish the effluent and meet the ammonia requirements. An ultraviolet (UV) disinfection unit was also installed within a small building at the site for improved disinfection.

The treated effluent has met the regulatory discharge permit limits of 7 mg/l BOD5, 90 mg/l TSS, 125 count/100 ml E Coli, and 2 mg/l Ammonia as Nitrogen since it was put into operation in 2007.

 

Ertel Cellars Winery
Batesville, Indiana
EnviroFilter™ 3,000 gpd
PRMF Wastewater Treatment System


A new winery wanted to locate in southeastern Indiana in a rural area without sanitary sewer service. The winery's wastewater would be considered high strength due to the winemaking and the planned restaurant included in the project. The winery's location was in an area with slowly permeable clay soils that would require pretreatment of the wastewater prior to soil disposal.

The project consisted of the installation of a 3,000 gallon per day package wastewater treatment system, 2,000 gallon FOG trap for kitchen waste, zoned gravity trench absorption field for treated effluent disposal, and electronic monitoring using a digital microprocessor control panel with modem capability.

The package wastewater system included two 3,000 gallon precast concrete primary treatment (septic) tanks with effluent filters, one 3,000 gallon EnviroFilter™ reinforced fiberglass tank attached growth package recirculating media filter (PRMF) for treatment of domestic wastewater, and zoned gravity trench absorption field for treated effluent disposal.

The treated effluent has met the regulatory discharge permit limits of 30 mg/l BOD5 and 30 mg/l TSS since it was put into operation in 2006.

 

Mt. Healthy Elementary School
Columbus, Indiana
EnviroFilter™ 6,000 gpd
PRMF Wastewater Treatment System


An existing elementary school located near Columbus, Indiana had a 6,000 gallon per day (gpd) extended air package treatment plant that was in non-compliance with its NPDES permit. The school did not want to replace the plant with another activated sludge plant due to the high O&M costs and was looking for alternatives.

The project Architect determined the EnviroFilter™ system required much less operational supervision, maintenance, and generated much less waste sludge. The overall operation, maintenance and equipment replacement cost for the EnviroFilter™ system was a fraction of the cost of the existing package sewage plant.

The project consisted of reuse of the existing gravity sewer collection line, the abandonment of the existing extended aeration package sewage plant, the installation of a 6,000 gallon per day EnviroFilter™ package wastewater treatment system, addition of a new sand mound for treated effluent recycling, and electronic monitoring using a digital microprocessor control panel with modem capability.

The package wastewater system included one 15,000 gallon single wall fiberglass reinforced plastic primary treatment (septic) tanks with commercial effluent filters, one 10,000 gallon EnviroFilter™ single wall fiberglass reinforced plastic tank with attached growth package recirculating media filter (PRMF) for treatment of domestic wastewater,

The treated effluent has exceeded the regulatory discharge permit limits of 30 mg/l BOD5 and 30 mg/l TSS since it was put in operation in 2005, while treating flows in excess of 200% of the design flow due to sewer leakage.


Westmoore Family Restaurant
Robbins, North Carolina
EnviroFilter™ 6,000 gpd
PRMF Wastewater Treatment System


A well established, popular rural restaurant near Robbins, North Carolina faced closure due to a failed septic system. The restaurant’s owner wanted to expand the facility, but found that the existing septic system was in non-compliance with regulatory requirements. The existing system needed to be replaced and enlarged to handle the proposed expansion.

The project consisted of the installation of one 3,000 gallon precast concrete grease trap, 6,000 gallon per day EnviroFilter™ package wastewater treatment system, addition of a new lined earthen basin effluent storage basin chlorine tablet disinfection system, effluent pump station to a surface drip irrigation recycle field, and electronic monitoring using a digital microprocessor control panel with modem capability.

The package wastewater system included one 12,000 precast concrete tank for primary treatment (septic) tank with effluent filter, one 12,000 EnviroFilter™ fiberglass tank with attached growth package recirculating media filter (PRMF) for treatment of domestic wastewater.

The treated effluent has met the regulatory discharge permit limits since it was put into operation in 2005.

 

Pelican Sound Subdivision
Hampstead, North Carolina
EnviroFilter™ 3,720 gpd
PRMF Wastewater Treatment System


The developer of the Pelican Sound subdivision in Hampstead, NC had several lots that were not acceptable for conventional septic disposal. The developer decided to use the EnviroFilter™ package wastewater treatment units at those lots and collect and dispose of the treated effluent using a community disposal field.

Individual residential EnviroFilter™ units in precast concrete tanks are installed at the designated lots as the residences on those lots are 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 pressure dosed drainfield on property within the development. The collection system and drainfield was completed in 2005 and EnviroFilter™ installation is ongoing as the lots are developed.

 

Joyce’s Restaurant
West Harrison, Indiana
EnviroFilter™ 3,150 gpd peak capacity,
high-strength PRMF Wastewater Treatment System


Joyce’s Restaurant was ready to open for business after extensive renovation by new owners when the county health department discovered that the existing onsite septic system had failed. Due to the small lot size and the high strength of the wastewater, a conventional septic system could not be installed. The county health department recommended use of the EnviroFilter™ package wastewater treatment system with drip irrigation effluent disposal.

An EnviroFilter™ system was quickly installed under a design-build contract in order to expedite opening of the restaurant. The system included a 3,200 gallon precast concrete tank grease trap, a 3,200 gallon precast aeration treatment tank with a regenerative blower and coarse bubble diffusers to reduce the organic loading of the wastewater, a 3,200 gallon precast concrete settling tank with return sludge pump, a flow distribution lift station, six 600 gpd precast concrete tank EnviroFilter™ treatment units in parallel, and a subsurface drip irrigation disposal field.

The system was installed in 2000 and has been in compliance with the Indiana State Department of Health effluent requirements since system startup.
