Heavy Duty Plastic Water Tanks
Water storage is one of those things that quietly holds everything together. When it works, you do not think about it. When it doesn’t, everything slows down.
At FSP New Zealand®, we build products around that reality. Our agricultural range has been shaped by real use across farms, lifestyle properties, and commercial setups. From troughs to storage systems, everything is designed to handle daily demand without becoming another job on your list.
Our plastic water tanks are built with that same thinking. Strong, practical, and made to keep working without constant attention.
Explore Our Water Tank Range
We focus on sizes that make sense in real setups. No unnecessary complexity, just options that fit how water is used on site.
1500 Litre Water Tank
Compact and easy to manage. This tank works well for smaller properties, backup supply, or specific areas where you need water access without installing a larger system.
3000 Litre Water Tank
A reliable everyday solution. Suitable for a wide range of uses including livestock, general farm use, or residential storage. It strikes a balance between capacity and convenience.
Built for strength and consistent performance. The one piece moulded construction reduces weak points and helps prevent leaks over time. Its shape supports even pressure distribution, making it a dependable choice for long term outdoor use.
The tank also helps maintain water quality by limiting light exposure, reducing the chance of algae build up.
5000 Litre Water Tank
When demand is higher, this tank provides the extra capacity needed to keep things running smoothly. Ideal for larger properties, livestock operations, or situations where water supply needs to be dependable through dry periods.
Where These Tanks Work Best
Every property uses water differently. The right tank depends on how and where it is needed.
Our plastic water tanks are commonly used for:
- Livestock watering systems
- Rainwater collection and storage
- Irrigation support
- Backup water supply during dry seasons
- General farm and property use
Because the range covers both compact and larger capacities, you can build a system that suits your setup rather than adjusting your setup to suit the tank.
Choosing the Right Tank
A quick way to think about it:
- Limited space→ Slimline 3000 Litre
- Small or secondary use→ 1500 Litre
- General purpose storage→ 3000 Litre
- Higher demand or multiple uses→ 5000 Litre
Getting this right from the start saves time later. You avoid under sizing, overcomplicating, or needing to upgrade sooner than expected.
Built for Long Term Use
The real value of a tank shows over time. That is where build quality matters most.
Our Water tanks are designed with:
- One piece moulded construction that removes joins and weak points
- High quality polyethylene that resists cracking and wear
- UV stabilised material for long term outdoor exposure
- Strong wall structure that holds shape under full load
- Light reducing design to help maintain water quality
These are not features you notice on day one. They are the reason the tank is still performing years later.
Installation That Stays Simple
You should not need a complicated setup just to install a water tank.
Our tanks are designed for straightforward installation:
- Easy to position due to manageable weight
- Compatible with standard fittings and plumbing setups
- Stable base requirements without complex preparation
- Flexible placement across different property layouts
Once installed, they settle into the background and do their job.

FAQs
How long do plastic water tanks last?
A well-made plastic water tank can last many years when properly installed. Because our tanks are UV stabilised and moulded in one piece, they are designed to handle outdoor exposure without cracking, rusting, or weakening over time.
Which size water tank do I need?
It depends on how you plan to use it:
- For smaller or backup use, a 1500 litre tankis often enough
- For general day to day use, a 3000 litre tankworks well
- For higher demand or livestock use, a 5000 litre tankis more suitable
If space is limited, a slimline 3000 litre tank is a practical option without sacrificing capacity.
Are plastic water tanks safe for drinking water?
Yes, as long as the tank is made from food grade material and installed correctly. FSP tanks are designed to store clean water safely, and their light reducing design helps limit algae growth.
Do plastic water tanks grow algae inside?
Algae can form if sunlight enters the tank. That is why our tanks are designed to limit light penetration. This helps keep stored water cleaner for longer and reduces maintenance.
Where is the best place to install a water tank?
A stable, level base is essential. Most tanks are installed on compacted ground, concrete pads, or prepared surfaces near downpipes or water sources. Placement should allow easy access for connections and maintenance.
Are plastic water tanks better than metal tanks?
Plastic tanks do not rust, corrode, or require internal coatings. They are also lighter, easier to install, and generally require less maintenance over time, which makes them a practical long term option for many properties.
Can I use these tanks for livestock water supply?
Yes. Our plastic water tanks are commonly used to support livestock systems, either as a primary source or as part of a broader setup with troughs and distribution lines.
Do I need maintenance for FSP water tank?
Maintenance is minimal. Occasional cleaning and checking fittings are usually enough. Because there are no joints or internal coatings, there is less risk of wear or damage compared to other materials.
How do I choose between a slimline and round tank?
It usually comes down to space and placement:
- Slimline tanksare better for tight areas or along walls
- Round tanksare ideal for open spaces and offer strong structural balance
Both perform well, so the choice depends on your layout.
