TETHYS · Irrigation engineering for South Africa

Every field, planned against forty years of weather.

Farm irrigation design and optimisation for South Africa, from a one-hectare smallholding to a multi-thousand-hectare estate. TETHYS finds the farm and its fields, runs a daily FAO-56 water balance for each, then designs the pumps, pipe and storage within the water law and prices every part at current South African rates.

TETHYS is a Protoworks product. Tethys: Titaness of fresh water, mother of the rivers, sister of Hyperion.
