1. A computer implemented method for managing a public utility wastewater collection system, the steps of which comprise:

  • (a) establishing a computer-accessible database, the database including wastewater collection system parameters, the collection system parameters including pipe system parameters comprised of the location, with respect to a coordinate system, of sewer pipe and manholes, the elevation of the pipe and manholes, and pipe and manhole diameter; and

    the collection system parameters including predicted customer wastewater input into the system along the pipe;

    (b) selecting an area of the wastewater collection system for analysis;

    (c) selectively reviewing portions of the database information related to the selected area;

    (d) selectively modifying database parameters;

    (e) determining at least one wastewater flow for a portion of the pipe system under analysis;

    (f) determining at least one surface hydraulic grade for a portion of the pipe system under analysis; and

    (g) comparing the surface hydraulic grade against a predetermined criteria.
