Floating Filter Intake: Why use for rainwater harvesting

A floating filter intake draws water from just below the surface of the cistern where water quality is naturally highest because heavier particles settle to the bottom and lighter debris remains on the surface. This ensures cleaner water is delivered to the pump and downstream treatment, reducing wear on equipment and improving overall system performance. By consistently pulling from the cleanest zone in the tank, floating intakes help maintain higher water quality and minimize maintenance needs.

Frequently Asked Questions About Rainwater Collection Tanks

Selection depends on required flow rate, pressure (TDH), and the distance and elevation to your point of use—ensuring the system can meet demand reliably.
An appropriately sized pump ensures consistent pressure, efficient operation, and reduced wear.
Submersible pumps are commonly used because they are efficient, quiet, and designed to operate within the tank environment. Centrifugal above ground pumps are also commonly used and has an advantage of being easily accessible when troubleshooting is required.
Yes—when paired with a variable frequency drive, a pump can adjust output to match changing demand and maintain consistent system pressure.
An undersized pump may fail to meet demand, while an oversized pump can lead to inefficiency, excessive cycling, and premature wear.
No—since water is pre-filtered before entering the tank, floating intakes are less prone to clogging compared to inline filters.
Yes—in higher flow systems, multiple floating intakes can be installed in parallel to meet system demand.
By consistently supplying cleaner water to the pump, it reduces strain on downstream equipment and improves overall system efficiency and longevity.
