There are no federal, regional, state or local requirements for odor dispersion control that require monitoring; the program was driven internally by the decision to be a “better neighbor” for businesses and residents near the treatment plants and reservoirs.
The original pilot program began 6 years ago and competitor was brought on site after members of management became interested in their “real time odor dispersion” model. Other products were quickly ruled out. After several years of use the client determined the competitor program was not delivering expected results, critical shortcomings were:
“ Sensors were unreliable – too much drift – system required onsite calibration at extra costs – ongoing visits from technicians at were inconvenient and costly – local environmental groups and legal groups discovered the use of the competitor products and began making inquiries for data – competitor data was “unreliable” and exposed the client to potential legal challenges “.
Shortly thereafter the Cairsens® micro-sensor was observed at a local air waste management show and the client decided to purchase product for evaluation.
The Cairsens® evaluation period ran through 2018 alongside the original competitor products and the decision was made to choose the Cairsens® micro-sensors. The positive deciding factors for Cairsens® were the following:
“ Cairnet® system was user friendly – no need for calibration – remote access of data – remote system access for Cairpol technical team – long life of the sensors – liked that the Cairsens® system was “real time data/numbers” and not modeling – progression to cellular transmission of data – Caircloud® software was easy to use “ .
Cairnet began full scale implementation in November of 2019; a total of 14 Cairnet® mini-stations have been operating continuously to monitor H2S/CH4S to provide the facility with robust recordings to address any potential community concerns of odor complaints from residents and businesses operating nearby. We are now in year 2 of a 3-year contract with the client.
