The parties, owners of adjacent residential tracts, were in a battle over water drainage.  The plaintiffs claimed that the defendants unlawfully constructed an earthern berm that obstructed the flow of water in a drainageway and caused the water to back-up onto the plaintiffs' property.  The plaintiffs also claimed that the defendants altered the course of another drainageway, moving it closer to the plaintiffs' property line which would endanger their property in the event of a major rainfall.  The defendants sought an injunction to stop the plaintiffs from pumping water onto their property and an order for money damages for loss of trees due to excessive water. The plaintiffs were discharging water via a sump pump through an underground pipe so that water would not get into their basement.  The pipe was connected to another pipe beneath the defendants' property, but the system failed and the plaintiffs began discharging the water at the property line.  The defendants then obtained a permit to build a second culvert and an earthen berm where the plaintiffs' dewatering well discharged the groundwater.  A pipe was installed through the berm to facilitate drainage.  Ultimately, water backed-up onto the plaintiffs' property.  When the plaintiffs discontinued the use of their dewatering well, problems ceased.  The trial court denied the plaintiffs' request for injunctive relief and also denied the defendants' counterclaim for tree damage/loss and denied an injunction that would bar the plaintiffs from discharging water via the dewatering well.  On appeal, the court affirmed.  The court noted that the water at issue was comprised of both surface and ground water, but the pooling issue involved groundwater that was pumped from the plaintiffs' sump pump and dewatering well.  The court applied the common enemy rule to the ground water and held that the defendants were free, as owners of the servient estate, to dam the water if necessary and reasonable under the circumstances.  The court held that the defendants' conduct was reasonable.  Thus, the plaintiffs were not entitled to an injunction on that issue.  The court also determined that the defendants were not entitled to money damages for their trees due to a lack of proof of causation.  The court also determined that the defendants were not entitled to injunctive relief stopping the plaintiffs from using their dewatering well.  Kobza v.
