A presentation was made concerning this at a recent meeting.
One of the best solutions proposed was a prefabricated concrete
structure that is provided by a manufacturer and shipped to the site by
truck or rail where available. Apparently they cost about $6000 plus
shipping. However, the good
news is that they are virtually indestructible by vandals, weather, wear
and tear, etc. Additionally, they contain a sloping vault which is lined
with a heavy polyethylene liner, so that even if ground shift or
earthquake would crack the vault, it would still prevent seepage into
groundwater. Service providers like it because it has an outside access
point for pumping and the sloping vault permits a quick and thorough
evacuation. Setting the structure in a sand base will lessen the chance of
ground shift or earthquake causing structural damage.
The customer provides excavation for the vault, and a crane to set the
structure in place, then backfill. The structure meets all federal,
state, and local requirements and guidelines for storage, prevention of
seepage, odor control/ventilation, etc.
Estimated life on the structure is probably 30 to 50 years, so even though
initially expensive, may be a good long-term, and low-maintenance
investment for the facility. It is aesthetically acceptable since it can
be "color coordinated" with the natural outdoor setting by having the
manufacturer color the concrete to match local rock/flora color settings.
No painting or general maintenance is necessary thereafter.
Federal, state and local park services are starting to use the structure
as well, for the reasons outlined above.
