Here's how you can follow up on this idea. Downtown trash recepticals are emptied by the Town Green Special Services District. Here is a link to the staff site: http://www.towngreendistrict.com/town-green-staff/
Recepticals outside of the downtown area are emptied by the Department of Public Works. You can follow up with them here: http://www.cityofnewhaven.com/PublicWorks/index.asp

You can contact either or both to present your ideas. You would want to make sure that these containers do not interfere with the process of emptying the trash and it would also be a good idea to provide examples of how they would attach, cities that employ these, how long they have been used in cities, possible benefits regarding reduction of landfill, safer for pickers to remove, cost to the city....etc.

Thanks I know both DPW and Town Green comment here as well. If they have thoughts posting here would be great.

I have looked at the cans and would like to take a stab at building a holder for the tops of these cans. I was going to test this at Chapel and State if it does not bother anyone.

I would suggest bringing this up with the director of DPW and getting an ok and also with the Downtown Special Services District, otherwise it will most likely be removed if there is no communication established. See above comment, which iterates these steps.

Yup. Got it thanks!
