53 Pa. Stat. § 14464
If, however, the cause of contamination by human excrement is incidental to the conduct of some legitimate business, or of a municipality, and does not amount to a common nuisance, the said board shall cause a petition to be presented to the court of common pleas of the county in which the said business is carried on, or the municipality is situated, asking for the abatement of the matter complained of, which petition shall set forth fully the causes for such action; and thereupon a citation shall issue to the party or parties complained of, directing them to show cause why the matter complained of should not be abated. The party or parties thus complained of shall file an answer within ten days after the service of the said citation. The matter shall then be proceeded with and heard before the said court of common pleas, in the same manner as injunction proceedings are now conducted, and after a full hearing of the parties and witnesses the court shall make such order as the circumstances demand.
