Hosepipe Controller
Approx construction cost US$64
How to avoid wasting money when watering your garden.
Before moving to their present home, the author’s family were fortunate in having an unmetered mains water supply. They could, therefore, use as much water as they needed for a fixed annual service charge. Times have changed. In the present house, water consumption is “clocked-up” by an outside meter.
One area where potentially large amounts of water can be wasted is in the garden. However, for many people the use of a hosepipe (lawn sprinkler, etc.) is practically essential. To avoid unnecessary cost, it is essential to manage the supply carefully and to use any hosepipe for as short a time as practicable. The Hosepipe Controller described here saves water by turning off the supply after a preset time.
