Hamilton County WWTA Emptying Grinder Pump Tanks Amid Area Power Outages

  • Wednesday, April 15, 2020

For customers currently experiencing a power outage from the Easter tornadoes, the Hamilton County Water & Wastewater Treatment Authority is providing a bit of good news.  They are deploying teams to empty wastewater from the grinder pump systems the WWTA maintains.    

The WWTA is working with local plumbing and electrical contractors to empty the tanks by use of a sewage pumper truck or a generator connected to the grinder pump system.  In continuing practices to protect customers and WWTA employees and their families during the current pandemic, workers will be observing the recommended social distancing guidelines while work is done.
Until normal power service is restored, the WWTA asks affected customers to limit water usage to a minimum until normal power service is restored.  If you are able to use some type of temporary power to operate appliances, please refrain from using your washing machine, dishwashers and/ or any other large water usage appliances.  

Below is a breakdown of the capacity of a grinder tank and the water usage for most households.  A grinder tank holds around 100 gallons of wastewater.

- Commode per flush - less than 2.0 gallons
- Washing machine per wash - 20 gallons
- Dishwashers per load - 10 to 15 gallons 
- Shower (10 minutes) - 20 gallons

Officials said, “We know these are difficult times and we are doing all we can to meet the needs of our customers.  We ask for some patience as the work is done and look forward to helping those who experienced damage from the weekend’s tornadoes.”
