Water and Wastewater for Multiple Units - How?

[Andrew Taylor]

I'm considering building a group of small single family residences on some property nearby. My intent would be to rent these out, not to subdivide and sell. I'm not sure what the density would be, but I'm thinking something like 4 or 6 units per acre. My question is, how do I handle water and wastewater if I am not served by city utilities? My experience is limited to building one house at a time on a single parcel, so I am familiar with water well and septic systems, but I'm not sure if the solution for multiple properties is the same or not. Is it just larger versions of the same systems, or are there other solutions more appropriate for a cluster of units? Thanks in advance for your input.
