I have found some images of Stainless steel water troughs. I think it is useful for you in supplying water in farm works.

Stainless steel water troughs was made by stainless steel, so it easy to cleaning. See how Removing Stainless Steel Stains : Cleaning Tips. Stainless steel does not absorb dirt; in fact, it actually resists smudges, fingerprints and scuff marks relatively easily, making it very easy to clean and maintain. Stainless steel appliances can be wiped down with a damp cloth and sanitized easily. The surface can be protected with a cleaner to preserve its smooth, sleek and shiny surface.

Stainless steel water troughs made by 304 stainless steel, so it will nearly never get in rust (corrosion). Do not care about dieases from corrosion. Because stainless steel is non-porous, it resists bacteria and germs more effectively than wood or plastic surfaces. Stainless steel can be wiped clean with a disinfectant cleaner after use, and is an attractive option for homes with young children and pets or for anyone who wants to keep their kitchen as clean and immaculate as possible.
