Rainwater tank (underground)
V.1
Klargester Environmental
In-line systems allow the water to back up through the tank and drain by gravity through the flow regulator. This system is normally used for installations where a fall through the system of 2.5-2.6 metres (on a sloped site) can be accommodated.
In-line Orifice Tank System V.1
An orifice plate system works on the principle that the pressure created at a particular head will result in a particular flow based on the head versus hole size.
This is a simple and inexpensive system.
