RE: snowey roads maintenance alternatives

Title: Message
What if major roads had drainage that got treated in combined septic/filter/wetland systems that were regularly maintained?  This would allow for settling out particles from tires (who pays attention to that?), filtering out some of the oily waste on filters that capture oil (if you maintain them you can change these regularly and capture a lot - Burlington, MA has done this in parking lots), and then if it went to a leach field that could biologically digest, (a constructed wetland with the right plants in it - they use these things to receive small wastewater plant discharges), perhaps beer sludge would indeed be the ideal replacement for salt.  This seemingly expensive approach would also reduce the runoff problem and enhance groundwater replenishment, paying for itself in the long run.  But without something like this - if beer sludge just runs off the road into a surface water, would it not be a BOD/nutrient problem?

Hi P2Tech,

Here is a question...

...looking for contract language and specs for environmentally friendly snow plowing.  I've heard there are good reports on the Sam Adams beer sludge alternative and am looking for ratios of sand to salt alternative (calcium chloride or whatever).  Any help will be appreciated.

Any suggestions? Thanks!

Adjusted for production, TURA filers have decreased their toxic chemical use by 45% and
are generating 69% less byproducts. During this same eleven years,  core TURA filers reported
an overall 45% increase in production!
