3400 Litres Stream Underground Rainwater Harvesting Garden System

• Collect and reuse harvested rainwater for garden irrigation and outdoor cleaning
• Low-profile underground tank reduces the excavation depth required
• Suitable for installations where a shallower tank profile is beneficial
• Strong and durable rotationally moulded polyethylene construction
• Complete Stream garden rainwater harvesting system
• Best One stainless steel submersible pump
• 10-year tank warranty

The 3,400 Litre Stream Underground Rainwater Harvesting Garden System provides a practical solution for collecting, storing and reusing rainwater around gardens and outdoor areas.

With a 3,400 litre storage capacity, the system suits medium-sized rainwater harvesting applications and can supply harvested water for garden irrigation, hose-fed watering, car washing, greenhouse watering, and general outdoor cleaning.

The 3400 litre tank is rotationally moulded from high-strength polyethylene and designed with a low-profile construction. Its reduced height means you may need a shallower excavation than with taller underground tanks, helping simplify installation.

The ribbed design provides additional strength, while the curved internal profile helps water at the bottom of the tank reach the pump efficiently.

When correctly installed and maintained, the tank is designed to provide a long service life and is supplied with a 10-year warranty.

What's Included?

This system combines the 3400 litre underground tank with Atlantis' Stream rainwater harvesting equipment, including:

• 3400 litre polyethylene underground tank
• Best One stainless steel submersible pump
• Patronen Filter
• Rodent guard
• 140 pump turret
• Pump lifting chain
• Delivery hose

Best One Submersible Pump

The Best One is a stainless steel submersible pump designed for clean-water applications.

Positioned at the bottom of the tank, it pumps harvested rainwater to the required point of use and is suitable for applications including:

• Garden irrigation
• Water transfer
• Hose-fed garden watering
• Car washing
• Greenhouse watering
• General outdoor water supply and cleaning

A pump lifting chain is also supplied to assist with retrieving the pump for inspection or maintenance.

Patronen Filter

The Patronen Filter, also referred to as a PF filter, helps remove debris from incoming rainwater before it enters the main storage area.

The filter uses a stainless steel mesh cartridge within a plastic housing. Its level-drop design and smooth internal surface allow excess debris to be rinsed through towards the overflow.

The filter is designed to be self-cleaning, although regular inspection is recommended to ensure effective operation.

140 Pump Turret

The 140 pump turret provides a flexible plastic connection between the submersible pump and the tank access point.

This allows harvested water to flow smoothly from the pump towards the delivery pipework and point of use.

Rodent Guard

The rodent guard helps prevent rodents and larger debris from entering the tank through the overflow, reducing the risk of contamination of the stored rainwater.

Delivery Hose

A delivery hose is supplied to carry pumped rainwater from the tank towards the required application. Hose options are available to suit different installation requirements.

Typical Applications

The Stream rainwater harvesting system is suitable for applications including:

• Garden irrigation
• Watering borders, beds and planters
• Lawn watering
• Hose-fed garden use
• Car washing
• Greenhouse watering
• General outdoor cleaning
