Montana's highway rest areas are more picturesque than other states resorts!

They have better wastewater treatment systems also. 

Eliminite has been selected as provider of all wastewater treatment facilities for Montana Department of Transportation (MDT) highway rest areas and other facilities.  Through its process, in conjunction with the Federal Highway Administration, MDT determined that it is in the best interest of the public for Eliminite to provide wastewater treatment systems for all its facilities. The systems are compact, reliable and specifically designed to treat the high nitrogen wastewater (ammonia =180 - 250 mg/L) common to highway rest areas. 

***UPDATE***
(The prime engineers on this project refused to collect actual wastewater influent samples and instead, guessed at the BOD and TN values.  They are not good guessers, Actual BOD Influent averages about 1200 mg/L.  Actual TN Influent averages about 450 mg/L)
The foot print of the entire treatment system is about 20' x 40' and uses all locallly supplied precast concrete tanks.  That makes good sense for our local economy because area suppliers can provide equipment rather than shipping money out of state to import equipment from out of state, or country, suppliers. 

We can do this in any location using locally available tanks, and components because the design of the system is flexible and can be modified to accommodate almost any tank configuration.  This not only provides a boost to the local guys but also results in significantly lower overall cost.  As you all know, "pod" type systems must be shipped in from somewhere.

This system was started and sampled in the dead of winter and is already achieving about 98 % conversion of ammonia to nitrate.  No alarms, no malfunctions, no phone dialer.  The average mean temp was around 20 degrees F for the operational period.
