The opinion of the court was delivered by: Opinion BY Senior Judge Friedman
BEFORE: HONORABLE BERNARD L. McGINLEY, Judge HONORABLE JOHNNY J. BUTLER, Judge (P) HONORABLE ROCHELLE S. FRIEDMAN, Senior Judge
Spring-Benner-Walker Joint Authority (Authority) appeals from the October 4, 2010, order of the Court of Common Pleas of Centre County (trial court), which denied the Authority's post-trial motions and affirmed its prior judgment that the Authority did not reasonably require Richard J. Payne and Catherine A. Payne (Developers) to plug and permanently seal floor drains they built in the Lingwood Townhomes (Lingwood) complex. We reverse.
In 1998, Developers purchased land for the construction of Lingwood, which consists of twenty-six units in five separate buildings. They obtained a construction loan and various permits, including a sewer permit from the Authority. The sewer permit did not address the use or non-use of floor drains or condensate drains connected to the sewer system.*fn1 (Findings of Fact, Nos. 1-5.)
After construction of the sewer infrastructure for the first twelve units of Lingwood, the Authority inspected the property. For each unit, a floor drain and a condensate drain connected directly to the sewer system. The Authority's executive director, Robert Decker, who performed the inspection with two other Authority employees, informed Developers that the buildings passed the inspection. Between the time of the inspection and the completion of the units, no one at the Authority ever advised Developers that they could not connect floor drains or condensate drains directly to the sewer system. (Findings of Fact, Nos. 7-8, 11-13.)
In 1999, Developers constructed the remaining fourteen units of Lingwood in the same manner. The Authority inspected the sewer infrastructure, and Developers' connection of the floor drains and condensate drains directly to the sewer system passed the inspection. (Findings of Fact, No. 16.)
In 2006, the Authority enacted Resolution 2006-1 in order to prohibit the inflow of rain, surface water, ground water, runoff water or other water into the sewer system.*fn2 The resolution: (1) requires an inspection of all properties connected to the sewer system upon a change of ownership;*fn3 (2) imposes an inspection fee of $50.00 if the Authority finds an illegal connection; and (3) allows the Authority to issue a notice of violation requiring an owner to disconnect a device that contributes unlawful and unauthorized inflow to the sewer. (Findings of Fact, Nos. 19-22.)
Section 4.17 of the Authority's rules and regulations prohibits floor drains, except at the Authority's discretion.*fn4 The provision does not prohibit condensate drains.*fn5 (Findings of Fact, Nos. 24-25.)
Subsequently, Developers attempted to convey a Lingwood unit to a third party without disconnecting the unit's floor drain and condensate drain from the Authority's sewer system. Developers requested that the Authority exercise its discretion under section 4.17 and grant an exception to Resolution 2006-1 because the Authority had inspected and approved the drains in 1998. (Findings of Fact, Nos. 26-27.)
Ultimately, the Authority stated that, before conveying any Lingwood unit, Developers would be required to permanently plug any floor and condensate drains by placing a compression fitting into the drain and sealing it with hydraulic cement. Developers objected because the Authority had no proof that any spring water, ground water or surface water has entered the sewer system through the floor drains at Lingwood. Moreover, if the Authority had prohibited the drains at the time of the inspection in 1998, Developers could have remedied the problem at a cost of $100.00 per unit. Developers projected that the current cost of permanently plugging and sealing the drains would be $3,000.00 per unit.*fn6 (Findings of Fact, Nos. 28, 30- 31, 37.)
Developers brought suit against the Authority under section 5607(d)(9) of the Municipality Authorities Act (Act), which states in relevant part:
Any person questioning the reasonableness or uniformity of a rate fixed by an authority or the adequacy, safety and reasonableness of the authority's services . . . may bring suit against the authority in the court of common pleas of the county where the project is located .
53 Pa. C.S. §5607(d)(9). The trial court entered judgment in favor of Developers, applying the doctrines of vested rights, variance by estoppel and equitable estoppel to the case.*fn7 The trial court found that: (1) Developers reasonably relied upon the Authority's approvals of the drains in the Lingwood units to spend $1,650,000.00 to complete the Lingwood units; and (2) the Authority did not enforce section 4.17, prohibiting floor drains, until November 2008. The trial court also concluded that the Authority's inspection fee of $50.00 is not uniform because it is applied only to properties with floor drains that have changed ownership. The Authority filed post- trial motions, which were denied. The Authority now appeals to this court.*fn8
The Authority argues that the trial court erred in applying the doctrines of vested rights, variance by estoppel and equitable estoppel rather than the ...
