53 Pa. Stat. § 2332
Whenever any city or borough or township of the first class shall desire to connect with the sewer of any adjacent municipality, for sewage purposes, an application shall be made by councils to the court of quarter sessions of the proper county, setting forth that fact; and if the court shall be of the opinion that this can be done without in any way impairing the usefulness of the existing sewer, it shall appoint three viewers, who shall personally view and inspect the sewer and the proposed connection therewith, and investigate all other facts in the case, and levy and assess the damages, or proportionate part of the expense of building the original sewer, which the petitioning municipality should pay, and also fix the proportion of the expense for repairs which each municipality shall thereafter bear, and determine all other questions liable to arise in connection therewith; and thereupon report to the court the result of their investigation and deliberations, which said report shall be confirmed within thirty days after the filing, unless an appeal should be taken therefrom, which appeal shall be prosecuted as similar appeals are now by law required to be prosecuted; and either party may appeal from the decision of the court of quarter sessions.
