No one budgets for a septic system failure. A new residential
septic system can cost anywhere from $4,000 to more than
$20,000, or higher, to install. If the system is not maintained,
the soil around the system could become clogged causing
house. The bottom line is that rebuilding a failed septic sys-
tem is an expensive burden on the homeowner.
Preventing a septic system failure is easier and more afford-
able than it is to correct. By keeping harmful materials out of
the system and by pumping out the septic tank at least every
three years, the homeowner can protect their system against
premature failure. The minimum cost of having the septic
tank pumped is wise insurance to protect your home’s waste-
water system.
This Manitoba Owner’s Manual outlines the principles of
septic system operations and explains the basic maintenance
procedures that will lengthen the life of your system. If prop-
erly operated and maintained, your Eljen wastewater system
can provide many years of trouble-free service.
This manual applies to the Eljen GSF System in Manitoba.

The Eljen GSF System

The Eljen GSF Geotextile Sand Filter system is a cost-effective
upgrade from other septic technologies. Unlike other systems
that treat efuent only once, the GSF’s patented Bio-Matt™
pre-treatment process treats septic efuent twice. That means
that the soil can absorb the efuent more readily, resulting in a
better-performing system in a smaller area than other systems.
TESTED FOR PROVEN PERFORMANCE
The Eljen GSF system technology is based on research
conducted by nationally recognized engineering scientists from
the University of Connecticut. Eljen Corporation has over 30
years of success in the onsite wastewater industry, with tens of
thousands of systems currently in use. The GSF is recognized
by regulatory ofcials and experts in the industry as one of the
most reliable wastewater treatment technologies in the market-
place today.
The GSF technology is based on scientic principles which
state that improved efuent quality provides increased soil
absorption rates. GSF’s proprietary two-stage Bio-Matt™
pre-ltration process improves efuent quality while increasing
reliability and ease of operation.
• Incoming efuent and bacteria ow through the perforated
pipes which distribute the efuent over the GSF Modules.
• Open air channels in the Modules allow benecial bacteria
to grow on the Bio-Matt fabric and treat efuent.
• A geotextile fabric covers the top and sides of the GSF
Modules, protecting the system’s sand and soil from ne
particles that can clog the system. It also helps maintain
efuent storage inside the Modules.
• After efuent passes through the GSF Modules, a lighter,
secondary biomat forms on the layer of specied sand
below the GSF Modules, where the treatment process is
continued.
• Treated efuent is then absorbed by the native soil where
nal ltration takes place.

and the overall operation of an Eljen GSF System.
•Porous Top of the GSF System
allows evapotranspiration and
oxygen exchange for better
efuent treatment.
•Anti-Siltation Fabric
keeps nes out of the GSF System
•Untreated Efuent
•Bio-Matt™ Fabric
•Cuspated Plastic Core
provides separation between
layers of Bio-Matt™ fabric.
Maintains structural integrity of
Modules & aids oxygen transfer.
Increases treatment surface area

•Filtered Efuent
•Treated Efuent
Perforated Pipes

Pipes are secured to the GSF Modules
with preformed metal clamps.
