Hi Matt,
The type of pump you need will depend on the head of water to pump,you mention 65m from well to storage tanks,but its the height you will need to calculate.
The well at only 2ft below surface of field will always attract surface water,to eliminate this i would sink your bottomless tank well below this level,and seal around the base with semi dry concrete or even good clay if you have it,and make sure tank top is well above ground level.
If the source of the spring is as good as you say,then you should be able to rise the level of water in tank above ground level,and be sure of no contaminated water entering.
I have done similar a few years back,but used concrete rings,the 2nd ring was a foot above ground level,and in 2or 3 days it was overflowing,so i placed another ring on top,against every bodies recommendations,but i raised the water level to 3ft 6in above ground surface.
This was for gravity feed to water troughs for the cattle in the lower fields when the gutters dry,as they have this year. |
