No. The storm water drainage system and the wastewater system are completely separate. The storm water drainage network of ditches, streams, and underground pipes carries away runoff water from storms and also from hoses and sprinklers. This water goes directly back to rivers, lakes, and streams without being treated. The wastewater sewer system takes water which goes down the drains inside your house or business. This water from sinks, toilets, washing machines, etc. is collected and sent to the Pecan Creek Water Reclamation Plant and is filtered and treated before it is discharged.
