Proper Procedures For Treating Your Water Well After A Flood

Flooding causes wide-spread damage in some cases. When you have a water well, the clean-up process requires a little more work than those with city water. Here, you'll learn what to do regarding your well following a flood.

Safety First!

It is possible that the flood waters have damaged the electrical elements of the well pump. If there was rushing water around your well, it is best to contact an electrician to inspect the system prior to making any attempt to repair it. Failure to do so could result in electrical shock.

Drain the Well

Flood waters contain sand, soot, and debris that could have made its way into your well tank. If you attempt to run water through the system without cleaning the tank, you could cause the pump to suck up debris and damage it or the clog the waterlines leading into your home.

Open the tank lid and carefully lower a sump pump into the tank. Run the drain hose away from the well and turn it on. Continue to let the pump run until the tank is empty.

Refill and Shock

Allow the tank to refill and then shock the water. Shocking the water will kill any bacteria or viruses that have been washed into it. Find out the holding size of the well. You must know this to add the right amount of bleach to effectively kill bacteria without overdoing it. You need to add one gallon of bleach for every ten gallons of water.

Mix the bleach with water in buckets before you dump it into the tank. This will help the bleach disperse more evenly and treat the tank quicker. Turn the well pump on and let it run for a minute and then turn it off. Do this repeatedly for a few hours to mix the bleach into the water.

Restore power to the pump and turn on the exterior water fixtures to run the water out of the tank. If you don't have a septic tank for treating wastewater, you can run the water through the fixtures inside your home as well. You don't want all of that bleach to be run into the septic system, or it could kill the bacteria that the septic system needs to function properly.
