The lid on the inlet hole is secured with an electronic lock. Once a credit card payment is made at the adjacent credit card reader, the lid is unlocked for one minute to allow the placement of the dump hose. It is recommended to have the hose connected to the RV in advance. Rinse water, which is not suitable for drinking, is available from May through October. To get to the waste water treatment plant, head west from Brady Street, bear right at Douglas Street, turn left at Lorne Street, and then turn left at Kelly Lake Road. The waste water treatment plant can be found on the right side.
