Product Information

Full details

This 5000L Underground Water Storage Tank is designed for homeowners and landscapers seeking an efficient solution for rainwater management and infiltration. It effectively collects rainwater from drain pipes, stores it, and then allows it to infiltrate into the ground, reducing surface runoff and potentially lowering water taxes. While it offers substantial storage, its effectiveness in poorly permeable soils depends on maintaining a minimum 1.5m distance to the groundwater level.

Extended Product Information

FAQs

What is the primary purpose of this underground water storage tank?

Its primary purpose is to collect rainwater, store it temporarily, and then allow it to infiltrate into the ground. This helps manage stormwater runoff, prevents soil erosion, and can be part of a sustainable water management strategy.

Can this tank be used for drinking water?

No, this tank is designed for rainwater harvesting for landscaping, garden irrigation, or infiltration purposes. It is not suitable for storing potable water.

What are the connection sizes for this tank?

The tank features 110mm connections for drain pipes.

How do I know if my soil conditions are suitable?

The tank is suitable for permeable and poorly permeable soils, but it's crucial that the distance between the bottom of the well/tank and the groundwater level is not less than 1.5 meters.

How often should I clean the filtration system?

It is recommended to inspect and clean the filtration system periodically, especially after heavy rainfall, to prevent clogging and ensure optimal performance. An annual check is a minimum.

What is the total storage capacity of the tank?

The tank has a total storage capacity of 5000 liters (5000L).

Does the tank come with a lid?

Yes, all tanks come with lids and filtration systems.

Troubleshooting

Tank not draining to infiltration system

Check the inlet pipe and the connection to the infiltration system for blockages. Clean any debris from the basket filter and ensure the infiltration area (gravel bed) is not compacted or clogged.

Slow infiltration rate

The surrounding soil may be compacted or the groundwater level may be too high. Ensure the gravel bed is properly installed and maintained. Verify the distance to the groundwater level meets the 1.5m minimum requirement.

Water backing up into drain pipes

This indicates a blockage or full capacity. Inspect and clear the main inlet pipe and the tank's filtration system. If the tank is functioning correctly, the issue may lie with the downstream infiltration system.

Tank lid is not secure

Ensure the lid is properly seated and secured according to the manufacturer's instructions. Check for any obstructions preventing a flush fit.

Pros and Cons

Pros

  • Reduces surface water runoff and potential stormwater taxes.
  • Facilitates rainwater harvesting for landscaping or other non-potable uses.
  • Helps manage water in areas with drainage challenges.
  • Can be integrated with eco-friendly household sewage treatment systems.
  • Substantial 5000L storage capacity.
  • Comes with necessary filtration and a lid.

Cons

  • Requires careful consideration of groundwater levels (min. 1.5m distance).
  • Installation complexity for underground systems.
  • Effectiveness in poorly permeable soils is conditional.
  • Does not provide potable water.
  • Requires regular maintenance of filtration systems.
  • Potential for freezing in colder climates if not installed correctly.

Setup, Compatibility & Care

Setup:

  1. Excavate a suitable pit for the tank, ensuring adequate space for the tank and surrounding gravel layers.
  2. Prepare the base with a stable, level foundation (e.g., sand or gravel).
  3. Position the tank, ensuring it is level.
  4. Connect incoming drain pipes to the 110mm inlets.
  5. Connect the outlet for the infiltration system to a prepared gravel bed or absorbent well.
  6. Backfill around the tank and infiltration area with appropriate gravel of suitable granulation, ensuring proper drainage layers.
  7. Ensure the lid is securely fastened.

Compatibility:

  • Compatible with standard 110mm drainage pipes.
  • Can be integrated with household biological sewage treatment plants.
  • Suitable for use in both permeable and poorly permeable soils, provided the groundwater table is at least 1.5 meters below the base of the well/tank.

Care:

  • Periodically inspect and clean the basket filter and any other filtration systems to prevent clogging.
  • Check connections for leaks or blockages.
  • In areas with freezing temperatures, ensure the system is installed below the frost line or take appropriate winterization measures.
  • Annual inspection of the gravel bed and infiltration area is recommended to ensure continued permeability.
