Having lined two of the three boreholes, the next stage was to raise the water to the surface, and bring it to a place where it is useful. One borehole would supply the house itself, and the other borehole would fill the south charca (storage pond) nearer to the house for later use in irrigation. It also has connections to the spring, to the orange orchard/vineyard, and to the tank near the house. We had two estimates for the project of bringing power and water to the house, and decided on a flexible system in which both boreholes can supply domestic water, and the lower (irrigation) borehole is pumped by a solar photovoltaic system. This means that on sunny days when water is most needed, the sun would pump it out of the ground.

Paulo the engineer and I got on well together, and he quickly understood what was needed.  In April 08, as soon as the weather was dry they started work on the 4feet-deep trench linking the lower furo (borehole) and the electric connection board to the house over 200 metres away.

On the satellite photo the red line denotes the limits of our land, green lines are the perimeter of olive grove (olival) areas, and orange is a vineyard with orange trees.  The dark yellow line is for electricity, and blue for the water pipe.

At the same time he put a mains electricity water-pump into the domestic borehole, and linked both lines in the garage via an H- system. This should allow us to choose either of the boreholes to supply the house.  Every day, he brought a big bag of bread rolls, some beers and meat to barbecue; Janet made salad and I cooked the sausages and steaks for lunch, which we all ate together on the patio in the sunshine.

On the second day of work (Friday), they arrived before 8am and asked if they could use my tractor to fill in the trench and level the ground as the tubing was laid. They clearly enjoyed working for us, carrying on into the dark, and finishing at 9pm – so much for the week-end starting on Friday lunchtime!

Lowering the pump, its water-level sensors and electrical supply line into the 100metres deep well.

They worked all day Saturday and two hours on Sunday morning too. In return for the loan of my tractor, they wired lights and a power point into the house. The end of an era; until now, lighting was by candles, storm lamp and an Aladdin No23 paraffin lamp -a luxury to read by, but so much work . . .

View northwards to the house, all the tubes buried and trench filled.

By Tuesday the guys had connected both the water and electrical systems, and we now have our own granite-filtered water from the house furo, supplied to a tap in the garage. The granite house has no plumbing so we have to go to the garage for water, which is an improvement on trailing into the village with two ten-litre containers and filling them at the village hand pump.  At this stage (May08) the lower furo still has no pump.

Water is the blood of the earth.  So in bringing a new farm to life it is necessary to find a subterranean artery and draw off a supply to the surface, where live the plants, the animals, and us.  Being a scientist I know all about seismic surveys, but dowsing, well that’s an arcane art and therefore worthy of closer inspection. For our search, my money’s on the dowser!

After a few walks holding his dowsing spring (an arch of spring steel) extended in front of him, Sr Antonio suggested drilling the first hole very near to the house.  We arranged a date for drilling the borehole.

Several weeks later, bright and early, we had just breakfasted on the patio in the sun, when a lorry towing a chunky yellow trailer appeared over the hill between us and the village. It hesitated a minute before winding its way along the road and arriving at our farmhouse. The wide lorry carried drilling tubes and the trailer was a solid engine packed into a steel casing, a powerful compressor as tall as a man.

Out jumped Sr Antonio, smiles and handshakes, who said there was a corner in the village which was too sharp for the drill lorry.  It had to turn round and find another route and would be here soon, don’t worry. No surprise there, the single-track cobbled streets with sharp turns are not suitable for heavy machinery.  He walked the proposed drilling site with his dowsing spring to confirm where the hole should be in order to strike the underground stream which would yield our drinking water.

A large blue drilling lorry arrived – how ever did he get here? – and the drill was deployed. An air line was connected to the top of the drilling rig which was carefully levelled.  The impressively solid yellow machine was started and the peaceful quiet ambience of birdsong was obliterated by the roar of the compressor.

Rotation… and the drilling head bit into hard-packed soil. As it quickly sank to the rock below, the dull rumbling of its passage into the ground changed to a more pervasive “Brrrr” underfoot and the rattling of the impacts at the top of the rig took on a hard-edged metallic hammering rather like a supersized overpowered pneumatic drill, which is essentially what it is.

Early in the afternoon at forty metres depth there was some water in the powder which was blasted up through the hole by the huge compressor. The borehole yielded more water at 75 metres down. Great! Not what I’d expected, though.

I had visualised seeing water gurgling up around the drill, winching the pipes up, and a fountain of water showering around. No, nothing like! There was no water coming out at all.  The workmen stopped at six o’clock, just leaving it all as it was.  They returned early the next day.  All the water that had accumulated overnight was blown out of the hole and it was re-cleared an hour later. Disappointment, “muito fraca”. Only enough for homestead use (70 litres an hour) even with storage.

Sr Antonio walked the land with his dowsing spring and suggested drilling in the olive orchard, so the entire convoy was moved.

This second borehole was dry even over a hundred metres down.  All the land is on granite, a hard rock, so drilling is slow and expensive. Each hole takes two days to set up, bore, find out how fast the water is being produced (the caudal ),then to de-rig the drill. We now decided to line the first well as the water is of excellent purity.

Lastly they started drilling a borehole on the lowest part of our quinta and I had to return to the villa, leaving the “Captagems, aguas subterraneas” men to do their best. A day later Sr Antonio phoned to say they had struck water, estimated at 700 litres an hour and would continue to drill to 110 metres for a further source. We decided that this borehole should also be lined to enable us to irrigate crops and fill the three charcas (storage ponds) on our farm. Do we have a pump so we can start using the water? No, because we have no electricity yet.
