Neptune Storm Water Crates – Advanced Stormwater Management Solutions

Engineered for Performance. Designed for Sustainability.

Neptune Storm Water Crates provide industry-leading stormwater attenuation & soakaway solutions for domestic, commercial, and infrastructure projects. Designed with exceptional strength and a 95% void ratio, Neptune Crates deliver maximum storage efficiency and outstanding structural performance.

Our systems ensure sites remain protected during heavy rainfall events, reduce pressure on drainage networks, and support long-term, sustainable water management across all development types.

Neptune Attenuation Systems

Neptune attenuation systems are engineered to temporarily store excess stormwater during intense rainfall and release it into the drainage system at a controlled rate.
Designed for reliability and strength, our modular units:
– Reduce peak flow and prevent downstream flooding
– Offer 95% void ratio for maximum storage per cubic metre
– Provide exceptional load-bearing capacity, suitable for roads, car parks, and HGV trafficking
– Integrate seamlessly with SuDS-compliant flow-control devices
Ideal for impermeable or restricted infiltration sites, Neptune attenuation tanks provide robust, long-life performance.

Neptune Soakaway Systems

For sites with suitable ground conditions, Neptune soakaway crates deliver efficient infiltration of rainwater directly into the surrounding soil.
These systems:
– Reduce surface runoff
– Help recharge groundwater
– Prevent overloading of local drainage infrastructure
– Provide rapid installation and long-term durability
Neptune soakaway systems are perfect for residential developments, landscaped areas, and commercial properties looking to manage water naturally.

  • Fully compatible with SuDS guidelines and planning requirements
  • Ideal for domestic, commercial, and civil engineering projects

How Neptune Crates Work

1.

Rainwater enters the system from roofs, hard surfaces, or infiltration points.

2.

Water is stored within the high-void matrix of Neptune Crates.

3.

Release or infiltration:
– In attenuation systems, water is released slowly through a flow-control device.
– In soakaway systems, water infiltrates naturally into the surrounding soil.

4.

Flooding is prevented, network loads are reduced, and site drainage performance improves.

Frequently Asked Questions

  • What makes Neptune Crates different from standard  attenuation crates?

Neptune Crates offer a 95% void ratio, giving greater storage capacity with less excavation. They are also engineered to withstand HGV loading, making them suitable for both light domestic use and heavy commercial applications.

  • Are Neptune Crates SuDS compliant?

Yes. Neptune Crates support infiltration, attenuation, and retention system types, all in line with SuDS best practice and current drainage regulations.

  • Can Neptune Crates be installed beneath driveways or roads?

Absolutely. When installed with the correct cover depth and backfill type, Neptune Crates are fully suitable for trafficked areas, including HGV-rated environments.

  • Do I need an infiltration test before installing a soakway system?

Yes. A percolation or soakage test should be carried out to ensure the ground is suitable for infiltration. If not, an attenuation system may be recommended.

  • How long do Neptune Crates last?

Manufactured from durable, high-strength polymer materials, Neptune Crates offer long service life with excellent resistance to environmental and structural stresses.
