Using values assigned to centroids along a network to constrain the length of a path.

I'm working on a project for a class involving creating a pipeline for distribution of recycled water. This pipeline needs to connect centroids of various polygons to a point representing a water treatment plant via an existing road map shapefile. The shapefile with the centroids has a field for how much water the centroid uses and the treatment plant has a field dictating its capacity. What I need to figure out is how to generate a network that:

1. Connects the centroids to the treatment plant via the road network using the shortest distance possible.
2. The sum of the usage potentials for the parcels connected to the treatment plant must not exceed the capacity of the plant.

Unfortunately no one is my group for this project has used network analysts before so we aren't sure which if any tools within the network analyst tool set to use so any help someone can give me is much appreciated.
