Product Information

Full details

The Prosperplast 2000L Underground Water Storage Tank is designed for homeowners and property managers seeking an effective solution for managing rainwater runoff and storm water. Its key benefit is providing a significant volume for water retention, preventing excess water from overwhelming drainage systems or causing property damage, while also offering a source for later infiltration into the ground. A caveat to consider is the requirement for specific soil conditions and groundwater levels for optimal infiltration performance.

Extended Product Information

FAQs

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

Its primary purpose is to collect and store rainwater runoff, preventing it from overwhelming drainage systems, and then facilitating its gradual infiltration into the ground.

What are the connection sizes for this tank?

The tank features 110mm connections, which are standard for many drainage pipes.

Can this system be used in any soil type?

The system works best in permeable or moderately permeable soils. It is not ideal for heavy clay or impermeable soils unless soil conditions are amended. Crucially, the bottom of the well must be at least 1.5m above the groundwater level.

How does the infiltration system work?

When the tank is full, water flows into absorbent wells (typically bell-shaped without a bottom) which are surrounded by layers of gravel. The water seeps through the gravel and into the ground.

Does the tank come with a lid?

Yes, all tanks come with a lid for safety and containment.

How often should I clean the filter?

The frequency of filter cleaning depends on the amount of debris entering the system, but it should be checked periodically, especially after heavy rainfall.

Can this tank be used for storing drinking water?

No, this system is designed for rainwater retention and infiltration, not for potable water storage.

Troubleshooting

Water not draining from the tank into the infiltration system.

Check the filter basket for blockages and clean if necessary. Ensure the infiltration wells are not saturated or clogged with sediment. Verify that the groundwater level is not too high.

Slow infiltration rate.

The soil may be less permeable than anticipated or the infiltration area is too small for the volume of water. Consider adding more gravel or expanding the infiltration area. Ensure the groundwater level is sufficiently low.

Debris entering the tank.

Clean the intake drain pipes and ensure the basket filter is properly seated and free of damage. Larger debris screens may be needed at the pipe inlets.

Water pooling around the tank.

This indicates a potential issue with the tank's integrity or the surrounding backfill. Inspect the tank for leaks and ensure proper drainage around the installation site.

Pros and Cons

Pros

Efficiently manages rainwater, reducing runoff and potential waterlogging.
Provides a sustainable source for water infiltration into the ground.
Helps avoid taxes on discharged rainwater.
Discreet underground storage preserves property aesthetics.
Includes necessary filtration components.
Standardized connection size simplifies installation.

Cons

Requires specific soil permeability and groundwater levels for effective infiltration.
Installation depth must maintain at least 1.5m distance from groundwater.
Underground installation can be labor-intensive.
Requires periodic maintenance of filters and the infiltration system.
Initial setup requires careful planning regarding location and excavation.

Setup, Compatibility & Care

Setup:

Site Selection: Choose a location where the tank can be installed at least 1.5 meters above the groundwater level, in soil that allows for proper infiltration. Consider proximity to drain pipes and the desired infiltration area.
Excavation: Dig an appropriately sized hole to accommodate the tank and any associated infiltration wells.
Installation: Place the tank in the excavated area. Connect incoming drain pipes (110mm) to the designated inlets. Install infiltration wells, typically bell-shaped and bottomless, surrounding the tank or in a separate designated area.
Backfilling: Fill the excavation around the tank and wells with appropriate materials, such as gravel, to support the structure and aid in infiltration.

Compatibility:

Compatible with standard 110mm drainage pipes.
Suitable for use with rainwater from roof gutters and overflow from household biological sewage treatment plants.
Requires permeable or moderately permeable soils for effective infiltration. Not recommended for heavy clay or impermeable soils without extensive soil amendment.

Care:

Filter Cleaning: Regularly inspect and clean the basket filter to prevent blockages. Frequency depends on the amount of debris entering the system.
Tank Inspection: Periodically check the tank for any sediment buildup or damage.
Infiltration Area Maintenance: Ensure the gravel layers around the infiltration wells remain clear of debris that could impede water flow.
