Drama at Villa Cengkeh: The Water Well

Broken Pipe

16 June 2017, FINAL Update!  The new well is complete and the solar pump is in place and producing water.  The well was drilled to about 120 meters, 5 inch casing placed down to 105 meters, the pump is submerged at 90 meters and the water level is around 70-75 meters.  The well produces clear, colorless and tasteless water with 116 ppm total dissolved salts.

12 May 2017, Update - Things sped up and then hit more stone, then the pipe broke!  For the past ten days the team has been fishing for the broken pipe.  They succeeded yesterday and it is all out of the well today.  Hopefully (mudahmadahan), things will progress to the finish line soon.

20  April 2017, Update - Have had some breaks for Balinese holidays.  Only about 3 meters since last report.  In solid granite now!

1 April 2017, Update - Not an April Fool's joke!  After much trouble, it was decided to begin from the beginning a make a new well.  On the 14th of March, another ceremony was held to prepare the well site and the drilling began on the following day.   The new well has been progressing according to plan.  The process has been helped by a) having a good team doing the work and b) having a good source of water to use in the drilling procedure.  Currently at about 80 meters.

5 November 2016, Update - the drama continues.  While Susan and I were out of town the well workers were able to get down to about 95 meters deep and snag the infamous lost solar powered well pump.  Unfortunately, as they were pulling it up, it only came up about 15 meters before getting stuck.  They worked for days to release it and eventually brought in hydraulic jacks to pull the pipe up.  But it broke about 5 meters above the drill bit/old pump.

They have been thinking for about a week now about the next move.  We are five months into this pump retrieval saga.

29 September 2016, Update - a veil is lifted.  The well workers worked late yesterday as they thought that something was happening down deep.  At 18:30 one came running up shooting "lihat, lihat" (look, look).  I went down to the well site and they brought up the 60 meters of drilling pipe with their drill head having a second drill head caught on it.  The extra drill head had been blocking their progress.  Somehow they luckily snagged a drill head that the former team clearly had dropped down the hole.  Strangely enough it was upside-down!  
Now the mystery of why the other drilling team wanted to start drilling a totally new well has become apparent.  They never told anyone that they had lost a bit down the hole.  Their boss claims he is as surprised as I am.  In any case, the well workers are making steady progress today.  A welcomed change.
24 September 2016, Update.  The first team returned after number Two team faded out.  Their start has not been auspicious.  They had a serious pickup truck accident bringing the machine back from south Bali and then the boss severely injured his leg when they were moving the machine down to the lower leave where the well is.  He lost a lot of skin and we worry for infection.  The young guys currently working are not setting any records for action.
31 July 2016, Update.  The well drilling team has returned.  They have given up on the idea of getting the stuck pump out.  There have been pieces of it already brought up.  Now they are starting at the top and drilling a bore 3 inches larger in diameter and will go straight down to 140 meters.  There is a lot of rock.  The new casing will be larger and should not have troubles for the pump.  Six inches instead of four at the narrowest.
23 July 2016, Update:  The team has not worked for 3 weeks.  They returned to Java to celebrate Idul Fitri and were expected to return in one week.  What can we say?  The good news is that Roland has recently completed a good well at a nearby house and if worst comes to worst perhaps we can get water from there.  The other goods news is that there has been a good amount of rain in the past 3 weeks, so our need for watering the garden has been minimal.
24 June 2016, Update:  The team only works on occasion. They say they are coming, then don't show up.  The boss is a Mr. Doic.  He seems to have plenty of work to do, so this job doesn't really matter to him.  Most contractors in Bali are not like this.  But there is no choice now.  Once someone has started a job, it is next to impossible to find someone willing to replace them.  This whole well thing has become a fiasco and Roland and Tropis Living really cannot do anything about it.  I would never recommend solar powered wells in a location where one has access to good power mains which we do in Bali.  It is simply too complicated to justify the extra hassles and too expensive too.

11 June 2016, Update:  The special water well drilling team has been onsite for 3 days trying to get the stuck pump out of the well.  As of last night they had brought up 30 meters of the well lining and (what they believed to be) most of the steel cables, pipe and wires that had been connected to the pump.  Today is fishing day.  Wish us luck!

Tip for well drill to be used to fish out the stuck pump

Susan and I decided to take some risks and do things a bit less than conventional when we built Villa Cengkeh.  One central idea was to use solar energy as much as practical.  This included using two solar hot water heaters that are on the roof and doing a great job.

The other idea was to use solar to power pumps.  Specifically for the pool circulator and for the water well.  The pool pump from Lorentz is in place and is working well.  So far so good.

The third solar application for the deep (>100 meter) water well has not been as satisfactory.  For both solar pump systems we contracted with Matthias Wenisch of Prosol a local Denpasar Bali company.  

Matthias actually came toward the end of March and put a pump in, but too shallow, 70 meters. The well was bored to 150 m. I was not here then, but I think they had a problem lowering it (it got stuck) and the well drilling man is said to have told Matthias that there was water at 70 m. In any case there was no water and the head of the pump burned out.  He said a replacement would come from Germany in one or so weeks. In the meantime the project contractor organized to have an AC pump and we had great water while it lasted. 

In May Matthias sent some workers who pulled the AC pump and put a solar pump in place. It worked. However I knew something was fishy when he only connected a subset of the solar panels. After they left I looked more closely and saw that the controller was only for 1800 watts, not 3800 as specified in the contract.  Matthias became very difficult to reach. His wife said he was working in a remote location in Sumba.  Ultimately our contractor, Roland, spoke with Matthias who said the the replacement pump had not actually come in and he had wanted to be sure we had water.  We did, but it was not enough and Roland got water from the local village mains connected to supplement our need.  Due to the new gardens and not much rain we have really needed a lot of water. 

Now for the drama.  Matthias came today with all the correct equipment including the controller and higher output pump. Yet the gods were not favorable. While removing the 1800 watt pump it got stuck and one of the two wire cables used to suspend it parted when they attempted to raise it with block and tackle.  A couple of days later they used a steel pipe to try to push the pump back down.  It did not work.

Of course that pump still needs to come out and the correct one go down. The two pumps have the precise same physical dimensions, so I believe there is hope.  We are awaiting a new team of water well specialists to arrive and try to work it out.

I shall update later as data becomes available.
