Heavy rains caused raw sewage to overflow at the Wahiawa Wastewater Treatment Plant this morning (May 6), spilling into storm drains and entering Lake Wilson. 

            The spill, reported at about 5:30 a.m., occurred at four sites on the plant premises and totaled about 9,000 gallons of sewage.  The situation was brought under control by 10 a.m. when the overflowing sewage was diverted into holding tanks. 

            The State Department of Health was notified of the spill and agreed that sampling of the water at Lake Wilson was unnecessary because the lake was also being polluted by massive amounts of stormwater runoff caused by the rain.   Signs warning the public of the pollution have been posted around the lake.
