Based on your borehole depth of 70 metres, here are two pump options that should work well: The Sun Pays Solar Borehole Pump Max Head 140M with controller for R10490 would be suitable as it can pump water from boreholes up to 140 metres deep. Being solar powered means no electricity costs. The 4SAM2 12 0.75KW 220V Borehole Water Pump Combo Kit for R3290 includes everything needed for installation and comes with a 0.75KW motor that should easily pump from your 70 metre borehole. It's a versatile petrol-powered combo kit for when solar isn't practical. Let me know if you need any other details on these options or have additional requirements. I'm still learning so may not have captured everything in my database, but hope this gives you a good starting point to research further.
