Clint Humphrey, ORC, Scott Leonard, BORC,of the WWTF and Ernest Kitzman of the Sea Trail Golf Community were present. The facility consists of two separate treatment trains that are combined together at the effluent dosing tank before pumped to the storage pond that serves the Sea Trail Plantation development golf courses, Maples Course, Byrd Course and Jones Course. The facility is well maintained and produces quality reclaimed water. Both trains have received improvements since the last permit cycle to include painting of treatment structures and a complete cleaning of the train#1.There are plans to replace the turbidity meter in 2019.The facility is linked to West Brunswick WWTF's SCADA system which is staffed 24 hours a day.The facility is compliant with Permit W00012748. There was no record found for the calibration of the spray irrigation flow meter.According to the permit, section 111.8, all reclaimed water irrigation equipment shall be tested and calibrated at least once per permit cycle.The current permit expires on 04-30-2019.The flow meter should be calibrated before the expiration date. Signs were posted around the reclaimed storage pond notifying the public about reclaimed water use. Educational material or a sign posted about the proper use of reclaimed water should be made available to users of all three golf courses in addition to the signs that are posted around the storage pond. Please review comment sections of the inspection report for further details.
