OFS’ new Cool Springs Corporate Education Center, which when completed would have a education, logging and recreation facilities, Click Photo to Enlargewas too far from an existing wastewater treatment facility to make it economically practical to tie in to an existing municipal wastewater treatment facility. According to OFS, two geotechnical firms investigated soil conditions at the site and determined that a mound system would work but might have a limited life span. Another concern was the infrequent flows during periods when the center is not used.

OFS had a primary goal of building in an environmentally sensitive and sustainable manner. Their desire was to achieve LEED certification for the project under the US Green Building Council’s guidelines.

To support their “green” goals, OFS and architect/engineer Hafer Associates of Evansville, Indiana had three challenges associated with disposing of wastewater from the facility. First, and most importantly, they needed to ensure the onsite wastewater treatment system would not experience any problems and would protect the environment for an indefinite lifetime.

Second, was to treat the wastewater in an environmentally sensitive and sustainable manner without significant operations andClick Photo to Enlarge maintenance expenses.

The third and final challenge was to construct a wastewater system that would allow OFS to easily expand the educational facility in the future without a huge initial capital investment for an oversized and underutilized treatment plant.

Architect and Project Designer Jack Faber, AIA from Hafer Associates turned to Indianapolis-based Algaewheel Inc. for an onsite wastewater system using proprietary Algaewheel® technology to meet these challenges.

   
System Components:
The daily expected flow rate for the OFS onsite wastewater system was 5000 gallons per day based on the maximum daily capacity of 100 people. The anticipated waste strength was that of standard domestic waste of approximately 170 ppm for BOD and TSS. The resulting system design included six bacpac units for pretreatment, two 5000 gallon primary septic tanks with the added conservative measure of having an effluent filter on each, and a 1500 gallon dosing tank to dose the treated wastewater effluent to the absorption field.
   
Site Challenges:  

Completion of a soil investigation at the project site in conjunction with the proposed facility layout dictated that the most appropriate location for the wastewater system was approximately 2400 lineal feet from the main facility. The Algaewheel technology includes pumping of the wastewater into the bacpac treatment units so this provided the flexibility to put the system anywhere on the site. A duplex grinder pump station/equalization tank was installed outside of the main conference center. This tank equalized flows through the system as well as pumped the influent to the treatment site. Another combination pump station/equalization tank was installed near the maintenance building and horse barn. Flow from the two pump stations went to a single precast flow splitter box to disperse to the six bacpac units. A 1000 gallon grease interceptor was installed prior to the pump station at the conference center to capture any grease from kitchen waste.

Construction of the wastewater system occurred during June of 2007 over the course of 5 days. Installation of the system was relatively fast since many of the system components were assembled prior to delivery by Oldcastle Precast®.

   
Subsurface Disposal Field:
Based on soil conditions and the wastewater flow rate, the OFS project required an elevated sand mound as the disposal field with a .5 loading rate. There were 2 mounds, each mound approximately 5000 square foot sand basal area.
   
Maintenance:  
The system for OFS is maintained by Ron Hall, a twenty year Class IV wastewater operator from Huntingburg. Ron takes monthly influent and effluent samples for testing and performs visual inspection to make sure everything is operating properly. Test results have shown that the system, which was commissioned in September of 2008, is performing well within established effluent limits and requires very minimal maintenance.           
"The algaewheel system is the only on-site treatment system that I would recommend to anyone. It is relatively maintenance free, utilizes solar energy to drastically reduce operational costs as compared to other systems, it is operator friendly, and consistently produces an effluent that equals or exceeds modern activated sludge plants."

Results:  
OFS achieved LEED certification for the project which was completed in June 2008. The Onsite Wastewater System contributed points to the certification for Innovative Wastewater Design. According the OFS, the system is “quiet and efficient….we have high flow protection, low flow stability and room to expand the system as the multimillion dollar, multi-year, state of the art facility is expanded”
