Overflowing Ponds and Use Of Sump Pumps
With all the rain we have been having recently I find that the level in my pond is rising to overflow level very quickly requiring the application of the bucket to bring it down. Is there any device that can be fitted and used at intervals to pump out the water? Appreciate any advice. If the ground falls away on one side of the pool you can just run an overflow pipe from level with the water to somewhere it can drain safely. An extension of this principle is to have a bog garden next to the pool. OR a 'soak away'. Into both of these a tube can drain down into the bottom which is full of clean gravel. Bog gardens are in fact constructed with a liner full of holes and the whole of the bottom lined with gravel. On top of these lie upturned turfs. Drain the pool to below these. Employing technology, in this country we can get cheap sump pumps or cellar pumps for about £40-£50 ( they are cheap because they are only designed to work for relatively short periods at a time and they use a fair amount of electrical power These are the basic direct drive pumps that have been on the market for decades. Draper and Dab are two makes that spring to mind, but any hardware store sells a make that it will recommend. There is always one model that has a 'Float Switch' in every range of this type of pump. These switches control when the pump is turned on by the level of the water lifting a float attached to the side. By a simple arrangement of clasps or ties, this switch can be made to turn on when the water gets to an preordained level. Most of these pumps have got plenty of pushing power since they were designed to pump out flooded cellars, so with one of these there is no reason why you couldn't dispose of the water anywhere you can get a hose pipe to reach. There are other sorts of switches too, like the 'mercury' switch that can be employed to turn a pump on when the water gets to a certain level. Speak to a local electrical supplier or an electrician about them. |
