1700 USG GRAF CARAT Rainwater Harvesting Package with Submersible Pump
The 1700 USG GRAF CARAT Rainwater Harvesting Package is a complete underground rainwater storage and distribution solution for properties that need substantial water capacity without taking up valuable surface space.
Built around a 1700 US gallon GRAF CARAT tank, this package provides approximately 6,435 litres of rainwater storage. It combines internal filtration, accessible tank components, and a Grundfos SBA3-45 A submersible pump to create a clean, efficient system for collecting and using rainwater around your property.
The package is well suited for residential, acreage, landscaping, irrigation, and other non-potable water applications where concealed storage and dependable water delivery are important.
How the System Works
Rainwater collected from your roof is directed toward the underground storage tank.
Before entering the main storage area, incoming water passes through the Internal Optimax Filter, helping reduce leaves, organic debris, and other contaminants.
The filtered rainwater is then stored inside the 1700 USG GRAF CARAT tank.
The Dome Mini and telescopic dome shaft with lid provide convenient access to the tank for inspection and maintenance while allowing the access height to be adjusted during installation.
The Grundfos SBA3-45 A submersible pump sits inside the tank and delivers pressurized water when needed, making the system suitable for irrigation, garden hoses, and other compatible non-potable water uses.
Ideal Uses
This system can support a variety of applications, including:
- Garden and landscape irrigation
- Lawn watering
- Greenhouses and vegetable gardens
- Garden hose connections
- Tree and shrub watering
- Outdoor cleaning
- Washing tools and equipment
- Rural and acreage properties
- Supplemental non-potable water storage
Because the main tank is installed below ground, you can maintain more usable space above the system while still storing a substantial volume of rainwater.

Tips for Getting the Most from Your System
Choose the tank location carefully.
Plan the installation around roof drainage, access requirements, underground utilities, and future maintenance.
Size your catchment area properly.
A larger roof area can help fill the 1700 USG tank more effectively. Consider local rainfall and your expected water use when planning the system.
Keep gutters and downspouts clean.
Reducing leaves and debris at the roof level helps improve overall filtration performance.
Inspect the internal filter regularly.
Clean the Optimax filter as required to maintain good water flow into the tank.
Keep access points clear.
Make sure the dome and telescopic lid remain accessible after landscaping or final grading so the system can be inspected and serviced.
Use stored water between rainfall events.
Creating available tank capacity allows the system to capture more water during the next storm.
Plan overflow drainage.
Once the tank reaches capacity, excess water needs to be directed to a suitable drainage, infiltration, or stormwater area.
Protect the pump system.
Install the Grundfos pump and electrical components according to manufacturer requirements and local electrical standards.
