Technically, the basic concept of a water-carried waste system is still the same.
Water flowing by gravity is used to get wastes out of the house and then out of town.

To understand what is needed for the future, let's review how we got to where we are today. Wastewater collection and treatment developed in the City of Albuquerque much as it did in the rest of the United States.
