Farm reticulation system
Older poor quality water lines and connections are more likely to split and leak.
- Identify problem areas and mark locations of weak spots on a farm map.
- Gradually upgrade older sections to help prevent water loss.
- Replace ill-fitting connections to decrease the risk of leaks.
- Bring the problem areas to the attention of everyone working on the farm.
Water lines that are near the surface, run under races or over drains are at particular risk of damage. Mark the locations of these weak spots on a map.
- Bury the lines deeper to protect them.
- If renewing or replacing lines, bury them alongside a fence to give added protection.
- To prevent problems where water lines must go under races, place them inside a larger rigid pipe for protection.
- Where lines cross drains, strap them securely to the bottom side of a pipe or post.
- Bring these water lines to the attention of everyone working on the farm.
Regular check of troughs
Having a check and maintenance system for water troughs that staff are familiar with is an important preventative measure for leaks.
- Use time bringing in the cows to look out for anything on the farm that might need attention, such as overflowing or empty water troughs.
- Tilting troughs slightly toward the race will make it easier to spot water loss on the drive by.
- Carrying spare parts and tools on the farm bike allows for the immediate repair of simple problems.
- Schedule in regular trough maintenance. Include replacing troublesome ballcocks and checking balls, strings, arms and pins. Have a system to record and sign off these checks.
Map your farm system
A farm map can be used to outline details of the water system, highlight areas prone to leaks and losses, identify where improvements could be made and where meters should be/are installed.
Farm water maps are useful for relief milkers and staff so problems can be solved when you are off the farm.
Details should include:
- Main source of supply
- Other sources of water e.g. roof rainwater tank
- Any water treatment systems
- Number of water meters (if any) and location
Reticulation and storage
- Type of water lines (alkathene, PVC, galvanized, etc.)
- Locations of any isolation valves
- Water lines buried, on the surface, or both
- Storage tank(s) and capacity
- Alert system (e.g. pilot light, pressure gauge) to detect possible water loss
- Water cylinder/CIP drum filling automated or manual
- Plate cooler water recycled or once through
- Automated yard cleaning system or hosing
- Where equipment is kept to fix leaks or replace
Tip: Include on your map an indication of what is a fix and what is to be replaced when it breaks down. This will help to spread the cost of upgrades over a manageable timeframe.
Things all staff should know
Which staff member is responsible for water tasks?
This will help to ensure things are done regularly and smart water use efforts run smoothly.
What is the farm’s agreed yard wash-down method?
Significant amounts of water can be saved (or wasted) on the farm depending on how yard wash-down is done. Train new staff on this and review it with workers each season.
What is the procedure for dealing with leaks and losses?
Write down the steps you want taken when there is suspected water loss to ensure staff have a consistent approach. You could use a board to note the status of the problem while it is being attended to and to sign-off completion. Some experienced farmers say if it isn’t written down it doesn’t happen.
