Irrigation Driven Sump Pump

We have been wanting to improve the drainage in front of 6 green for several years.  During large rains our "French drain" sump fills with water and must be pumped out with a transfer pump.  In an ideal situation electricity would be available somewhere close and a simple electric sump pump could be hung in the catch basin.  But this area on 6 fairway is not near electricity so instead we used unique system developed by Turfdrain that allows us to move water without electric power.  In this application, irrigation water is run through a siphoning valve that then sucks the water out of the sump and pumps it through the outlet pipe.

This first picture shows the excavation of the old gravel fill sump.  This was complicated by the water still in the sump and the caving of the banks but Richeson Irrigation dug us a nice hole.


Here you see the new catch basin draped in erosion cloth to prevent contamination.  To the right is the 1" line that ties into the irrigation system.  To the left is the outlet piping that will carry the water up and over the hill to the east.  As you can see we backfilled with sand which should move water better into the sump and not get as clogged with sediment like the previous gravel layer.


The project nearly complete-just waiting for the sod..

 
Finally here is the working parts of the system.  You can see the float ball that will automatically open the siphon valve when water reaches a certain level in the catch basin.


We have been pondering doing this sump (which almost always holds water after any large rain event) for some time now and we are quite excited to have this really cool system installed and ready for the next thunderstorm.  Kudos to my crew that knocked this out in a day.
