Eljen & Enviro-Septic Systems
If you have a tight site and/or less than optimal native soil conditions, Eljen filters or EnviroSeptic units are great solutions that may be a cost effective solution helping you avoid more expensive and complex systems. Depending on the site specifications, these systems can be designed and installed with either gravity or pressurized distribution methods.

Eljen filters can be snaked through tight spaces (note the dog-leg in this system) when space is at a premium. Eljen filter installs are often 1/3 or less smaller than conventional system installations. The second photo shows the special fabric that goes over the Eljen Filters prior to back-filling.

The sand on top of the plywood keeps the Enviro-Septic tubes from moving out of level while backfilling around them. The plywood is removed once the filter sand completely surrounds the tubes. There is 12″ of filter sand beneath these tubes, then native soils below that. The tubes are installed completely level. Oxygen in this system is crucial to breaking down the effluent. The tallest tube in the second photo here is the oxygen intake port. The exhaust port is at the other end of the field 53′ away. The tube on the right is a monitoring port going down to the depth of the native soil. The other three tubes are also monitoring ports but they allow you to see what is going on in each of the three rows of Enviro-Septic units.
Bonnington, September 2016
Below are photo’s of a tricky install of a shallow Eljen system in Bonnington. This site was both steeply sloped and very rocky (shallow bed rock.) Consequently, we chose a narrow but elongated drain field using Eljen filters in groups of two with a couple feet between each group of two. The system also required dosing which was achieved through the use of a flout tank.

This is a pumped Eljen filter system. Effluent is pumped through small diameter pipe laid inside 4″ perforated drain pipe. The final photo shows the plumbing of the pump – ready for the electrician to wire in. Lot’s of rock at this site!
