More and more people are now
collecting rainwater to use in
garden irrigation,
toilet flushing and much more. Systems range from an old barrel at the bottom of a downpipe to underground tanks storing thousands of gallons of
rainwater and/or treated
greywater.
Klargester have a new
rainwater harvesting system called
Raintrap for garden watering and car washing etc.
Klargester Raintrap
Pictured above is an illustration of the
Raintrap
system in action. The existing guttering and downpipe of the property are connected to an
underground tank with integrated
water pump. An internal self-cleaning
in-line filter is used to prevent leaves and other debris getting into the stored water. This filter need only be checked annually (just after autumn) and can be removed, washed, and replaced if required.
If the tank should reach full capacity, any additional rainfall will be automatically diverted down the drain.
Water Pumping
Installed in the tank is a
240 Volt mains-powered pump. This pump can move water 100 metres on level ground through a 12.5mm diameter hose at a rate of 12.5 litres per minute. If the water is only to be pumped 30 metres, the flow will be 25 litres per minute. The pump has a life expectancy of around 5-6 years with no maintenance requirement during that time other than a periodic visual check.
12 Volt DC powered pumps (which could be powered directly from a
solar panel are not supplied as the company has not found a suitable pump to meet their performance requirements. The 240 Volt AC pump supplied can of course be powered by
PV solar panels via a suitable
power inverter.
A wall mounted switch is used to control the pump to deliver the
collected rainwater under pressure through the included 30 metre length of hosepipe. This standard-sized hosepipe can then be connected to any existing
water sprinkler system,
porous pipe irrigation system, water butt, or just used as is to water the garden, wash the car and so on.
Available System Sizes
Currently three different sizes of
water storage tank are available with capacities of 2800, 3800, 4600 litres. The smallest system costs around
£1,800 including full installation.
