Why choose an effluent bladder tank?

The demand for effluent bladder tanks has been continuously increasing, and with increased compliance measures, uncertain weather, and safety concerns it’s not hard to see why!

 

  • Additional Sump Storage – if you have a pumping system with a sump that handles most of the effluent storage, but need additional storage to handle rainy periods, or just to tick the box for council compliance, a bladder tank could be the solution.

 

  • Retention of Nitrogen Content – Nitrogen is a valuable fertiliser and this is one way to maximise the free stuff you’ve already got. Effluent stored in bladder tanks is more nutrient rich since it is not getting diluted by rainwater or evaporated into the atmosphere.

 

  • Reduce Your Workload – if you’re in a high rainfall area or have high water tables you’ll know the pain of large fluctuations in effluent storage levels due to rain. Of course after heavy rainfall, you can’t spread it until the ground dries up, leaving even more effluent to manage. Effluent bladders don’t have this problem. Being closed storage the effluent is not getting the rainwater added to it, leaving a lot less to manage.

 

  • Aesthetics – prefer not to see a big effluent pond when you look out the window? Bladder tanks can often be situated to blend into the landscape, making them less obvious, and they have much less odour.

 

  • Cost & Tax Advantages – bladder tanks between 300-500mᶾ hit the sweet spot when it comes to value, costing no more than installing a pond while having all the benefits of closed storage. What’s more, tax wise bladder tanks depreciate on your books, so after around 5 years you can write them off.

 

  • Multi-Location Storage –  got large or multiple farms? Increase your spreading efficiency by storing effluent in multiple locations. Slurry tankers can fill up from each location rather than needing to travel long distances to re-fill the tank and back again to spread around outer paddocks. It also means less disruption to cow flow and other farming operations.

Advantages

  • Very high mechanical quality
  • Better resistance to acidic and basic effluents
  • Specific design for flexible tanks
  • Hydrophobic coating for higher durability
  • Outstanding weight / resistance compromise
  • Anti-UV and anti-fungal formulation
  • Resistance to high and low temperatures

Do I Need to Stir an Effluent Bladder Tank?

As with any effluent storage system, it is critical that the bladder tank is thoroughly stirred. Bringing the effluent into suspension helps avoid heavy sediment building up on the base of the bladder and over time making it difficult
to mix in the future.

To adequately stir the bladder, utilise the ports around the tank by sucking effluent out through one port and pumping it back into the bladder through another port with a high-volume PTO effluent pump. (If a PTO pump is not available, then a very large capacity motorised trash pump could be an option).

Whilst pumping, a swirling motion is created bringing all the effluent into suspension. Switch to the opposite side to work around the different ports to make sure the tank is adequately stirred before irrigating.

On average, a bladder tank should be mixed for a minimum of 30-60 minutes, every one to two weeks. However, it may take longer if the tank has been left stagnant for several months. We recommend stirring thoroughly every time before the tank is emptied or any fluid is sucked out.

FAQ

Bladder Tank FAQ’s

1. Can using an effluent bladder tank help reduce methane emissions on my farm? 

Yes. Unlike open effluent ponds, which allow methane (a potent greenhouse gas) to escape into the atmosphere as effluent breaks down, bladder tanks are fully sealed. This sealed design greatly reduces the conditions where methane-producing microbes can thrive, meaning less methane is released. As a bonus, bladder tanks can also be paired with gas-capture systems, turning potential emissions into a usable energy source.

2. What are the necessary steps for preparing the ground?

Nevada provides you with a complete checklist for site preparation.

3. What is the optimal positioning for a Nevada water storage bladder tank?

Place the bladder tank on a stable, flat surface near the water source for easy access and maintenance. Ensure good drainage, avoid flood prone areas and comply with local regulations. Nevada provides a detailed checklist for the setting up and installation of your Bladder Tank.

4. What kind of maintenance do they require?

Bladder tank’s need regular inspections for leaks, periodic cleaning, checking valves and fittings, ensuring vents are clear, and maintaining any pumps according to instructions.

5. How durable are bladder tanks? (UV, punctures, seams, fabric)

Nevada bladder tanks use top-tier, rip-stop reinforced fabric with high tensile/tear strength and excellent flexibility to handle torsion. Seams are heat-welded, corners are four-pad reinforced, and outer coatings resist UV and fungal growth.
Durability still depends on correct installation and use: a smooth base, keeping sharp objects away, not overfilling (use the level gauge), and regular inspections.

6. What warranty comes with Nevada’s bladder tanks?

All Nevada bladder tanks come with a 10-year manufacturer’s warranty, starting from the date of manufacture. This warranty covers defects in materials and workmanship when the tank is used and maintained in line with the manufacturer’s guidelines.

See the bladder tanker warranty details here

7. How long do bladder tanks last?

They’ve been in some of the harshest conditions around the world and are still going strong after 20 years.

8. Are they designed for effluent storage?

Yes, the Nevada bladder tanks are specifically built for liquid effluent storage. They’re designed to hold dairy effluent safely and effectively.

9. Where are they manufactured?

All Nevada bladder tanks are manufactured in France. The manufacturer is ISO9001 certified for the design and manufacture of bladder tanks.

10. Can you move a bladder tank later after installation?

Yes, our effluent bladder tanks can be moved after installation. They’re designed to be somewhat portable and flexible, allowing for relocation if necessary.

11. Is there a possibility that the bladder tank can burst?

Our bladder tanks are built to withstand tough conditions, but as with any effluent storage solution, damage is possible if they are misused or exposed to unexpected events. The main risks include punctures from sharp objects, overfilling past the tank’s limits, or accidental damage from machinery.

Regular inspections and proper usage in line with the manufacturer’s guidelines will greatly reduce this risk. Every Nevada bladder tank is supplied with a colour gauge to indicate capacity levels, and for our standard stocked sizes, the bladder tank must not be filled beyond 1.5 metres. (Refer to Question 5 for more details.)

12. What is the capacity range of Nevada’s water storage bladder tanks?

We hold capacity range from 300m³ – 2000m³, Although the range available for indent is from 1m³ – 2,000m³. You can also join bladder tanks together to create the volume you need.

13. What materials are used in the construction of a bladder tank?

Composite textile membranes are engineered with a PES (Polyester) woven reinforcement that delivers unparalleled dimensional stability and outstanding resistance. This makes them very flexible.

14. How long is the installation process?

Our installation process for bladder tanks typically takes a few hours to a couple of days, depending on the tank size, site preparation, and specific installation requirements. Nevada provides a complete checklist for site preparation prior to Nevada’s install team arriving on site. Setting up the bladder tank is normally completed within a day.

15. What size will I need?

To determine the size of the bladder tank you need, consider your water usage, application (residential, commercial, industrial), available space, and regulatory requirements.

16. What liquids are suitable to store in a Nevada bladder tank?

Our bladder tanks are built for cool water and dairy effluent/manure/slurry use. Remove as much sediment and solids as possible through sand and stone traps before the fluid enters the bladder tank.
