Attempting to privatize trash collection - city says I cant?

[Casey Miles]

I recently bought 2 fourplexes that share a courtyard but are legally two separate properties. These are located in Phoenix and currently there are 8 individual trashcans that for one, don't look good, and two, cost me roughly $225 per month on my water/sewer/trash bill. I contacted several private dumpster companies and it would cost $115 per month for a dumpster. I called the city to see about removing the trash service. They said they could provide a dumpster (for the $225 I am paying now) but because of a city ordinance I couldn't get a private dumpster. I researched the code and here is what it says:

27-21 Residential collection.

A. The City will provide solid waste collection service to all dwelling units including: *1

1. Single dwelling units.

2. All buildings with less than five dwelling units, including duplex, triplex, and four-plex units, and all buildings with five or more units that have been receiving City solid waste collection continuously since May 30, 1979. Multiple buildings on one lot cannot be aggregated to avoid the provisions of this chapter. *1 *2

3. The City may provide solid waste collection services to any building with five or more multi-family dwelling units but less than 30 units upon consent between the City and the responsible party. *1

4. Mobile home parks.

5. Mobile home developments.

6. Townhouses and condominiums.

7. Carryout service is provided at no additional charge to individuals living alone who are elderly, ill or disabled and are incapable of conveying their solid waste or recycling container to the designated collection location. This does not include entering the dwelling unit. The resident may be required to produce a medical statement of present physical condition. No carryout service will be performed if, in the opinion of the Director, the terrain presents a safety hazard for equipment operators or collection vehicles. The Director has the right to limit the number of containers. *1

8. Dwelling units that generate in excess of 0.50 cubic yards of solid waste at any given time may be served utilizing an alternate collection system and charged according to a different and separate fee structure based on collection and disposal costs. The fees will be determined by the Director and will be published by the Department. *1 *2

B. The City may provide service to institutional establishments if they request solid waste service. They will be charged a different and separate fee.

C. The City does not provide solid waste collection service to commercial or industrial establishments or to any building with more than 30 multi-family dwelling units, except as provided in subsection A.2 of this section. *

I read the code as the city has the obligation to provide service to buildings with less than 5 dwellings, not that it's mandated. I spoke with the private dumpster companies and they said the city will try and pull this on me. How do you suggest I go about handling the city and getting rid of the individual trashcans.

Thanks in advance,
