Big Green: Septic system alternatives

Wed Mar 12 21:52:57 EDT 2008

We just compared a system similar to what Bill describes to a conventional
septic system for a small group toilet in a park.  It would have been a wash
or even less given different soil conditions.

Ralph et al,

We typically use constructed wetland systems.  In more than a few cases they
have been less costly to install than conventional septic systems.
Particularly where soil strata and type require that leech field lines are
installed more than six feet deep.  The wetland Œwaste¹ water is at tertiary
level and with additional filtration is at a potable level.  Thus, we
install the leech lines (dosing lines in the case of wetlands) at 10² below
grade saving money.  We also save having to reserve an extra leech field
area because the dosing field has no suspended solids to clog it after years
of use. 

Best regards,

Bill

Jennifer:

I have no experience with the Dri-Let toilet system.  However this does
raise a related issue that we have been struggling with.  What are green
recommendations for replacing a conventional septic system?

As much as I like them, a living machine is probably not an option in this
case due mostly to cost. Residential septic systems are typically installed
for $10-15k so costs would need to be relatively comparable. We have also
heard of ³drip irrigation² systems but I have no experience with them.

Cheers,
Ralph Bicknese

Does anyone have experience with the Dri-Let toilet systems?  They're
billing themselves as an environmentally friendly self-contained, compact,
portable, electric powered toilet system that processes waste into a fine
ash.  I'd love to hear your reviews of the product, if any of you have used
it.  http://www.DriLet-America.com
