How do you know you are getting the frequency you need with your trash and recycling pick-ups? How can you be sure you are not paying for more pick-ups than are actually warranted? Corporate Property Services performs site surveys to monitor the levels of trash and recycling over a given period of time. Recommendations are made either to decrease frequency of pick-up or, in some cases, increase frequency of pick-up. The goal of the surveys is to enhance output efficiencies and to prevent overflow of trash and recycling.
