A faulty sensor caused the discharge of about 34,000 gallons of partially treated sewage yesterday morning into Lake Wilson, the city reported. Sensor blamed for

Signs have been posted in the area, the Department of Health has been notified and bacteria levels are being tested.
"Because the effluent was partially treated and the reservoir was closed, we don't anticipate it causing any serious environmental problems," said Department of Health spokeswoman Janice Okubo.
City spokeswoman Carol Costa said the discharge will not affect the cleanup of the salvinia molesta weed, which has covered the surface of the lake.
Costa said the sewage had not gone through the final ultraviolet disinfectant treatment because the sensor at the Wahiawa Wastewater Treatment Facility intermittently shut the unit down.
