If you live a little
way from the town in Monze a well provides a reliable water source
for growing crops and drinking.
John told me that all
he needed to dig his well was a pickaxe and a shovel. I was a little
sceptical, but a friend offered to fund the project (about £15 if I
remember correctly).
After a week or so J
appeared again! He had dug down about 6 foot. Now at this depth you
hit an issue – getting out of the hole.
There is however a
solution. You need a windlass, which is a device with a wheel and
handle. If you think of the top of a mine you will get the idea.You
pass a rope over this wheel and attach a bucket. The bucket is used
to take the soil to the surface. Oh, and to lower and raise J so he
can continue digging!
It just happened that
this was not my first well digging project and Jennipher had a
windlass that John could use. So sorted!
The windlass is hand
operated, so now we needed someone to operate it. John had a friend
who was willing to do this work. He would just need to be fed.
So onwards and upwards
– or more accurately dowmwards!!
All went well (no pun
intended) for a while. Then John came to me to say he was worried, he
had dug down to 50 or 60 feet. During this time the equipment had
been well tested and the rope was showing it! John said that it was
fraying and he was worried.
At this point I began
to wonder whether I should be involved! Anyway we obtained a new rope
and John continued to dig.
Eventually John hit
water. The test is that when you are lowered (perhaps 100 feet) into
the hole you bail out enough water to fill two large barrels. At this
point you can stop digging and you have your well.
However we now have a
very deep hole. It is towards the end of the dry season, but the
sides could still fall in – when the rains arrive the well will be
in trouble!
The solution is to line
the well with concrete rings or bricks. We decided therefore to buy
2,000 bricks to line the well – oh and a bit of sand and cement to
make the mortar.
Before John's well I
had a very bad experience when a little girl fell down a well. It was
very important therefore that John's well was capped.
The usual way of
getting water is by dropping a bucket into the water. However this
allows the water to become contaminated. Each year in Monze they have
a show which gives various organisations to exhibit their products.
Many years ago I was impressed by a “rope pump”. This goes over a
well and produces a sealed system which prevents contamination.
I decided to get John a
rope pump to complete his project.
The moral of this tale
is that when someone tells you they only need a pick-axe and a
shovel to build a well be wary.
Schedule of items for
building a well:
pick
shovel
windlass
rope
bucket
food for man 2
second rope
2,000 bricks
sand
cement
pump
The well was built just
before John decided to move. I never found out what happened to the
pump! Unfortunately I haven't got a picture of the well so this is a
different well!
