If you’ve read TM 9-2330-267-13&P (Dec 15*), you’ve probably seen this warning. It lets you know it’s not a good idea to wait until the last minute to clean your water trailer’s tank. And it’s not a good idea to leave water in the tank for months at a time!
Cleaning the tank improves the taste of the water and keeps the tank safe to use. The TM says to clean the tank annually or when the medics tell you the tank is contaminated. But why wait? You have to drink the water too!
Here are some PM tips to keep you from drinking slimy, rusty or metallic-tasting water.
Trailer on incline enables water to drain through the drain plug completely.
If the water from a stainless-steel tank has a rusty, metallic taste, check the weld joints in the tank for rust.
Rust on welded joints can cause metallic taste of water in tank.
Scrub away rust with a solution of water and scouring powder, NSN 7930-01-294-1116. Always use a nonmetallic, nylon brush. You can get one with NSN 7920-00-061-0038.
Flush the tank thoroughly with clean water. Scrub it again if you still see rust. You’re done when the rust is gone.
Look at TB MED 577 (May 10), Sanitary Control and Surveillance of Field Water Supplies, for more on cleaning.
