Case Study: Eljen System Addresses Onsite Challenges at Assisted Living Center

Eljen GSF System addresses onsite challenges at an assisted living center in Indiana

Eljen GSF Used in Finger Lakes NY

A new assisted living center in Lawrence County, Indiana, had been using a pump-and-haul service for over a year while it tried to figure out a solution for its wastewater.  The location originally reserved for a drainfield was unsuitable for an onsite wastewater system.

The center got an easement and purchased a nearby lot, however, a traditional system wouldn’t fit.  The site has a 3% slope and soils, and a daily design flow of 3,750 gallons per day.

Design considerations for this system were to make sure there was enough capacity to handle flows from the 35 apartments, laundry facility, and dining hall, as well as to adequately treat the wastewater stream.

The Solution:  Designer and engineer Ronald Burcham chose the Eljen GSF B43 for the project, due to the sizing reduction in square footage.  The system is comprised of a grease trap and a series of septic tanks, as well as two pump chambers and a sloped above-grade bed.

The effluent flows from the septic tanks to a pump chamber, which then pumps the effluent underground through the easements to another pump chamber where it’s then distributed to the GSF drainfield.  The drainfield has five rows of 29 B42 modules each, which are centrally fed by a distribution box.

The Results:  The assisted living center is now able to stop costly pump-and-haul service.  The new drainfield treats effluent to secondary treatment levels, and also allowed space to be reserved for a future system.
