Thanks for all the great info on this site.

Can anyone advise on this problem. I'm in the process of digging a new pond and due the high water table in my garden (only 12 ins of topsoil over heavy clay subsoil) I've had to locate the pond in an area I know will become waterlogged in the winter. I've read that the pond will therefore require drainage below the liner. OK so I'll excavate another 8 inches or so and sandwich perforated pipes in a layer of gravel. I don't have anywhere to direct this groundwater other than to collect in a sump and then pump into the nearest (12ft away) surface drain. Two questions please - the pond area is only 3.4m x 2.4m what can I use as a sump - I had thought about burying a plastic dustbin, is this a ridiculous idea ! Secondly any recommendations on a suitable pump - it would need to have a float switch and be rated for continuous use and need to lift the water around 1.5m ?

Many thanks for reading

A buried plastic bin is fine, or you could buy one or more of the soakaway/storage units shown on the [url=http://www.pavingexpert.com/drain08.html[/url] and use them.

Any pump with a float switch would be suitable. The Draper SWP 235ADW is a good choice as it can cope with larger particles that may,, inadvertantly, find their way into the sytem. It can cope with a lift (head) of up to 8.5 metres and can thrash out a respectable 235 litres per minute. A 240v model costs around 120 quid (plus the dreaded VAT, of course)
