The purposes of this Rule are:
Every privilege that is granted and every duty that is required by this Rule imposes an obligation on utilities, applicants and customers to accept these privileges and perform these duties with good faith, honesty and fairness.
This Rule defines the minimum standards for nondiscriminatory practices that all water utilities must follow. It does not, however, limit the power of utilities to give greater protection to their customers above these minimum standards.
