Best Water Tanks for Dairy Farms and Livestock Use

Clean, consistent water supply is the backbone of every successful dairy or livestock operation. Animals rely on fresh water daily for hydration, digestion, and milk production — and even a short disruption can affect performance. At Just Tanks NZ, we understand the demands of rural life, which is why our round and large-capacity polyethylene tanks are engineered to deliver dependable water storage for farms across New Zealand.

Why Quality Water Storage Matters on the Farm

A farm’s water system must withstand constant use, variable pressure, and harsh outdoor conditions. Inferior tanks risk cracking, contamination, or leaks that interrupt daily routines. High-quality tanks, however, ensure:

  • Consistent supply for milking sheds, troughs, and cleaning systems.
  • Clean, safe water free from rust and bacterial growth.
  • Lower maintenance costs through long-term durability.
  • Better herd health and improved milk yield.

Investing in the right tank protects both productivity and animal wellbeing.

Top Features to Look For

When selecting a water tank for dairy or livestock use, focus on the following essentials:

    1. Large-Capacity Design

Choose tanks that provide ample storage – often 10,000 L to 30,000 L – to meet daily farm demands and buffer against dry spells.

    2. UV-Stabilised Polyethylene

New Zealand’s strong sunlight can quickly degrade cheap materials. Just Tanks’ UV-protected polyethylene prevents cracking and algae growth for decades.

    3. Rural-Grade Strength

Round tanks offer superior wall strength and even pressure distribution – essential for rough terrain or wind-exposed sites.

    4. Food-Grade Safety

Ensure your tank is manufactured from food-grade, BPA-free plastic to keep livestock water clean and odour-free.

    5. Easy Plumbing and Access

Look for pre-moulded outlets, inspection lids, and compatibility with float-valve systems so you can connect tanks directly to trough networks or pumps.

Recommended Tanks for Dairy & Livestock Operations

At Just Tanks NZ, our round rural water tanks are the preferred choice for farms needing robust, high-volume solutions.

  • Round 10 000 L Tank – ideal for smaller herds or supplementary water storage.

Installation Tips for Rural Properties

  1. Choose a stable, level base of compacted gravel or concrete.
  2. Position near existing trough lines to minimise pipe length.
  3. Protect inlets and lids from livestock contact.
  4. Clean gutters and filters regularly to maintain water purity.
  5. Inspect outlets every few months for leaks or corrosion.

Proper installation ensures steady flow, safe pressure, and years of trouble-free use.

Long-Term Maintenance for Clean Water

Even the best tanks perform better with care. Drain and rinse interiors every 12–18 months, and flush pipes to remove sediment. Keep lids closed to stop dust or insects entering. This simple routine preserves water quality and prevents algae build-up, keeping your animals healthy year-round.
