Gebruik Water Level Indicator

Product Information
The system is build simple and reliable.
A pressure bulb pushes air into a tube that reaches all the way to the bottom of the cistern. The needle of the gauges correspondes with the depth of the water, as soon as bubbles come out of the nozzle at the bottom of the gauge. After pumping two or three times the needle reaches its maximum height. No matter how many times you pump, the pressure will not alter: You will just push more bubles out of the nozzle, but the reading remains the same.
Practically it means that you sqeeze the bulb two or three times until the needle doesn't go up any further. That's your readout. Simple and foolproof.

Since the installation is easy and fast, the first readout can often be obtained in matter of minutes

Rainwater General information

Rain Water Harvesting

Rain water is a free source of nearly pure water. It can be used to supply drinkable (potable) water and non-potable water. For non-potable uses, like watering landscapes, it is ready for use as it falls from the sky. 
For centuries the world has relied upon rainwater harvesting to supply water for household, landscape, and agricultural uses. Before city water systems were developed rainwater was collected (mostly from roofs) and stored in cisterns or storage tanks.
Today, many parts of the world, including Hawaii and the entire continent of Australia, promote rainwater as the principal means of supplying household water. On many Caribbean islands where rainwater is the most viable water supply option, public buildings, homes, and resorts all collect rainwater to supply their needs. In Hong Kong, rainwater is collected from skyscrapers to supply water needs.

If we all contribute in collecting rainwater, we aim for both a better environment as well as economical benefits.
