When it comes to livestock health, clean water is just as important as good pasture and quality feed. Yet many Australian farmers unknowingly compromise their stock’s wellbeing by neglecting regular trough maintenance. From algae build-up to waterborne pathogens, an unmaintained stock trough can quickly become a breeding ground for disease and decline in animal performance.
This guide will walk you through the importance of stock trough maintenance, surprising facts about livestock water behaviour, and practical steps to keep your water troughs clean, safe, and efficient all year round.
Why Clean Water Matters More Than You Think
You wouldn’t drink from a muddy, stagnant bowl—and neither should your livestock. Clean water supports digestion, nutrient absorption, and temperature regulation. Research shows that livestock drink more when the water is clean, leading to increased feed intake and better weight gain in cattle and sheep.
Surprising fact: A study by Colorado State University found cattle given fresh, clean water gained up to 23% more weight compared to those drinking from dirty sources.
Even more concerning, dirty cattle water troughs are ideal environments for algae, bacteria, and even parasites. These can cause anything from reduced growth rates and poor milk production to serious illnesses like leptospirosis or cryptosporidiosis.
Common Trough Contaminants to Watch For
Keeping your stock water trough clean isn’t just about looks—it’s about preventing dangerous contamination. Some of the most common threats include:
Algae: Green, slimy build-up caused by sun exposure, especially in summer. Some algae types release toxins harmful to animals.
Bird droppings and faeces: Contaminate water with E. coli and other harmful bacteria.
Stagnant water: Encourages mosquito breeding and fouling.
Decaying feed and organic matter: Can ferment and lead to foul odours and bacterial growth.
Chemical runoff: Especially near fertilised fields or industrial areas, leading to nitrate or heavy metal contamination.
Did you know? Cattle are surprisingly picky—studies show they’ll drink less if their water smells off or is too warm.
Step-by-Step Trough Cleaning Guide
Whether you’re caring for a single horse or a hundred head of cattle, routine maintenance of your plastic water trough is key. Here’s how to keep your troughs in top shape:
1. Empty the Trough Completely
Remove all water before cleaning. This allows full access to algae, sediment, and debris that settles at the bottom.
2. Scrub the Interior
Use a stiff-bristled brush or trough broom. Avoid using soaps or detergents unless labelled safe for livestock use—residues can deter animals from drinking.
3. Disinfect Safely
A mild bleach solution (1 part bleach to 100 parts water) is a safe and effective disinfectant. Rinse thoroughly with clean water to remove any chemical residue before refilling.
4. Refill with Fresh, Cool Water
Always refill from a clean water source. Ensure pumps and pipes are also free from contamination and sediment.
5. Repeat Regularly
In warm months, aim to clean every 1–2 weeks. In cooler seasons, once a month may suffice depending on use and exposure.
Tips to Prevent Trough Fouling
Prevention is just as important as cleaning. Here’s how you can reduce build-up and keep trough water clean for longer:
- Use shade: Install a trough shade cloth or select shaded areas to limit algae growth.
- Install float valves: Keeps water levels consistent and avoids stagnation.
- Elevate the trough slightly: Helps prevent contamination from splashback and surface runoff.
- Use a tank ball or float cover: Discourages birds and prevents debris from entering.
- Consider trough design: Rounded corners and smooth poly surfaces (like those on The Water Tank Factory’s troughs) make cleaning easier and reduce dead zones for sludge to accumulate
Why Poly Stock Troughs Are a Smart Choice
Not all water troughs are created equal. The Water Tank Factory’s range of poly stock troughs are built to withstand the demands of Australian farms.
Benefits of poly stock troughs:
- Non-corrosive and UV-stabilised for long outdoor life
- Easier to clean than concrete or galvanised metal troughs
- Lightweight yet tough—resist cracking, chipping, and deformation
- Smooth interior reduces algae adhesion and sediment build-up
- Ideal for cattle, sheep, goats, pigs, and horses
️ Bonus: Poly troughs are less likely to crack in frosts compared to concrete alternatives and won’t rust like metal troughs.

Signs Your Trough Needs Immediate Attention
Watch for these red flags:
- Murky or discoloured water
- Unusual odour
- Visible algae or slime
- Animals refusing to drink
- Excess sediment at the bottom
A good rule of thumb? If you wouldn’t drink from it, don’t expect your livestock to.
Smart Add-Ons: Accessories That Help
Modern farms benefit from more than just good design. Consider these extras to maintain clean, fresh water year-round:
- Automatic float valves – Refill troughs without manual labour
- Ball covers – Reduce evaporation and contamination
- Pump timers – Maintain optimal water levels and flow
- Trough filters – Catch debris before it settles
These additions don’t just save time—they protect your stock’s health and your farm’s productivity.
Final Thoughts: Clean Water = Healthy Livestock
Water trough maintenance might not be glamorous, but it’s one of the simplest, most effective things you can do to support livestock health and performance. With a routine cleaning schedule, smart accessories, and a well-designed plastic trough, you can avoid costly vet bills, improve animal wellbeing, and boost productivity across the board.
As we like to say—happy animals start with clean water.
