That's a great and very practical question! Getting the right size bins is crucial for keeping your building clean and avoiding extra fees. For a 20-unit condo building, you're typically looking at commercial-grade containers, not residential bins. Here’s a natural, experience-based breakdown.
First, don't guess. The best move is to call your current waste hauler. They know local rules, collection schedules, and can do a waste audit. They often provide the bins as part of the service contract.
That said, here's a general rule of thumb. A standard starting point is to estimate 2-3 cubic yards of compactable trash (like bags) per week for 20 units. However, this varies massively based on occupancy, resident habits, and if you have recycling/compost diversion.
You'll likely choose between:
1. Large Wheeled Carts (e.g., 95-gallon): If your collection is frequent (2-3 times a week) and space is limited, multiple 95-gallon carts might work. You'd likely need -4-6 of them for trash, plus more for recycling/compost.
2. Front-Load Dumpsters (2-4 cubic yards): This is often the sweet spot. A 3-cubic-yard dumpster, serviced 1-2 times per week, is a very common solution for a building of your size. It's secure, keeps pests out, and is efficient for the truck.
3. Rear-Load Dumpsters (6-8 cubic yards): If you have ample alley or driveway space and want less frequent pickups (once a week), a larger dumpster may be cost-effective.
Key factors to consider:
* Collection Frequency & Cost: More frequent pickups of smaller bins can sometimes cost more than weekly pickup of a large dumpster. Get quotes.
* Space: Measure your enclosure or pad. The hauler's truck needs clear access.
* Recycling/Organics: If you're adding streams, you need space for additional bins. This often reduces trash volume.
* Local Bylaws: Many cities have rules about bin types and enclosures.
My personal suggestion? Start by talking to 2-3 waste collection companies. Give them your unit count, current issues, and ask for their recommendation and quote. They'll tell you what size (in cubic yards) they recommend for your specific situation. It’s the most reliable way to get it right.
Hope this helps you navigate the process smoothly
