How-To: Clean & Maintain A Water Line

So many factors can affect the quality of poultry flock, but water is the most important. It’s easy to take for granted, especially in areas where water quality isn’t a daily concern. Drinkable quality and high quality are not the same, though. Paying close attention to the quality of the water will always result in a better-quality bird.

Mississippi State University composed a great article on the importance of high quality water and how it can be achieved. We will highlight some key takeaways here.

Closed does not mean clean.

When poultry was raised using open water systems – troughs and cups – it was easy to see when the water was dirty. Today’s closed systems still get dirty, clogged with mineral build-up and algae.

Water supplies are unique and dynamic.

No two wells are the same. Water supply can be affected by droughts or floods, site selection or well depth, or any number of other environmental factors.

It’s easy to mineral overdose.

Modern poultry feeds are perfectly balanced with the right amount of minerals and salts that a bird needs to grow. When the water carries too high a mineral load, it is easy for the birds to consumer too much, and performance will suffer due to poor digestive function, lower immunity, or other problems.

Biofilm

A complex community of bacteria, fungi, algae, encased in an extracellular polysaccharide attached to a surface. Or… that slimy green stuff. And it’s a breeding ground for contaminants. Additives often promote the growth of biofilm making it important that lines be flushed, cleaned, and flushed some more pretty regularly.

 

Be sure to flush long enough to completely purge the lines.

    • A general rule of thumb is to flush one minute for every 100 feet of water line.

 

Don’t overlook the pH of your water supply.       

    • In general, birds do not like to drink high pH water.

Water sanitation

    • Household bleach is likely the most commonly used water sanitizer on poultry farms

 

Reduce and clean biofilm

    • Stabilized hydrogen peroxide works well on biofilms because it is a very good oxidizer and can hydrolyze (or break down) the biofilm.
    • In addition, it is non-corrosive to the drinker system and quite effective on bacteria, fungi, and viruses.
    • It can break down algae thoroughly enough to allow it to pass through nipple drinkers without causing the nipple to clog or stick.

 

Over time, scale buildup can reduce the pipe volume and cause regulators and nipples to malfunction. If the pH of your water is above 7 and the water supply contains more than about 60 ppm of either or both calcium and magnesium, then scale buildup is likely.

 

To remove scale buildup from the water lines, you’ll need to use a strong, acidic cleaner that is safe for nipple drinkers and can drop the pH of the water to below 6.

    • Also remember that acids are not sanitizers. Acids are only part of a larger, overall sanitation program; they are not the entire program.
    • For example, if you suspect a biofilm problem, you’ll need to run a good sanitizing cleaner that can dissolve the biofilm before you use the acid.
