1. Who makes up your wastewater division?

The City of Cibolo’s Wastewater Division is currently made up of five employees, which consists of a Foreman, a Crew Leader and three Wastewater Technicians.  A Superintendent oversees the daily operations of both the water and wastewater divisions.

2. What does the wastewater division do?

The employees of this division are responsible for operating and maintaining the wastewater collection system.  This system includes:

• Force mains
• Gravity lines
• Lift stations
• Manholes
• Various pumps

The wastewater crews clean, maintain, and monitor all of these components of the system. In addition, the crews inspect lines and manholes, with video equipment to search for infiltration/inflow. Reducing infiltration/inflow achieves cost savings in treatment and facilitates a more reliable collection system.

3. What is a lift station?

A lift station pumps wastewater uphill and commonly to a point where it can gravity flow downhill again. A lift station is equipped with pumps, wet wells, and control systems the pumps force the wastewater through a pipe, referred to as a force main.  Not all wastewater lines lead to lift stations; some go directly to the wastewater treatment plant because the plant is lower in elevation than the homes it services. This is referred to as gravity flow.  

We currently have five lift stations in our collection system and all are monitored on a daily basis.

4. How is the wastewater treated?

In our area the Waste Water Treatment Plant (WWTP) is a regional WWTP, as such it treats waste water from Cibolo, Schertz, Randolph AFB, Universal City and others. It is operated by Cibolo Creek Municipal Authority or CCMA.
