Some people don’t know it, but part of water treatment involves sanitizing the piping, water tanks, and well. Often, putting a filter system on isn’t enough due to what’s already in the pipes. A sanitizing or “shock” of everything the water touches lets the customer start off with a clean slate.
What do you get when you fill a semi-transparent tank with warm, chlorine-free water and let sunlight hit it for several hours a day? You get 3,000 gallons of water that comes out a lovely shade of black.
Initially we used plain salt to dehydrate the algae and cause the larger chunks to break up, so they could be pumped out with a submersible trash pump.
As the water level drew down, a pressure washer was used to knock the growth off the walls of the tank and let the trash pump do most of the work.
Once the water level was low enough that the pump couldn’t work, our bravest technician Kevin climbed into the tank to scoop out the rest of the algae by hand.
With the entire tank exposed, we used a hydrogen peroxide solution to sanitize every surface, then began running fresh water back into the tank.
The tank was left with a chlorine residual above 10 ppm free chlorine for a long-contact chlorine shock, which also draws into the pipes downstream. Going forward, a chlorine feeder maintains a residual in the tank, and a carbon tank removes it before the water enters the home. That’s a complete water solution.
