Selecting a deep well pump is not so difficult once you know the head (height of the water column) and water volume requirement. That's all you would consider in the US or Europe.
Here periods of low voltage need to be considered.
I was discussing this with Perry Loo at Polaris last week. He said they could marry a 1hp impeller to a 1.5 hp motor which would allow the pump to function without overheating if the supply voltage is low.
You might want to check the voltage at your place before spending a lot of money on a pump.

 

I too live in Amlan , just before Silab on the Silab road. I build two ferro cement tanks 32 & 48 ton and depend on rainwater. If interested come and see, I may have some advise too.

 

the time also seems a bit out (one week) unless they know all ready that the land is indeed soft irrespective of how many men there is (7 seems a bit too much) but what do i know (if your are paying by the foot) versus day labour what difference does it make except its extra mouths to feed

we just gave them 300 pesos a day and let them do their own buying and cooking

again the pipes i bought from JB marketing the main man considered a bit soft and some of them bent (maybe they are throwing in some cheap ones along with good quality

so i guess matiao might be the way to go (you can only buy pipes in 20 feet lengths)
so they will have to be cut in half and threaded together that you can do locally im sure and not have the seller do it ( but they dont do the threading) another outfit near the fruit market did it (i forget) but it wasnt overly expensive, but ask the driller if some local cuts and threads, plus you also need some french coupling to join the the two threads together again

 

we just finished our well (116feet) rather effortlessly too, one drama was the pipes, we purchased from JB marketing (2 inch schedule 40), some of them bent and that was after we got past the rocky section (10-30feet), but other than that its all good
now gotta work out what pump and the other bits and pieces that go along with it, and get the water tested (went about that and was told no where in DGTE) can it be tested properly, yes it can be tested for a few contaminants but not all , across from the public hospital they told me they only check for bacteria and nothing else (my local LGU said no one in dgte had the national certification to test water, but i seen an ad for a place in Talisay that does it, as we might go down the road of a water station or just keep it for ourselves as we will be buying the water station kit to make our water alkaline .................fingers and toes crossed

 

Mine was about 27 ft (7 mrs) to clear but we went another 2 meters to make sure 5 years now and always water from the Pump.

 

Just about finished our project. Our local contractor charged P90k for the lot. The guy did a great job on our garden well - this one is on some land the wife owns and will supply resorts for profit and locals for cost. We bought the pipes, casings etc ourselves, I think a rough estimate arrived at about P30-40k for the lot. So a rough estimate arrives in your figures, as we hit the water table at 180 feet. Due to some unfathomable (ha ha) reason the contractor wanted to go down another 20ft. I trust him, so I agreed. So maybe we came in slightly less expensive. But as we live on Siquijor things are done within the family and as the baranguay will benefit the contractor was delighted that the foreigner was trying to make life easier for his relies in the baranguay.

Like you we are into submersible pumps. You are clearly avoiding Chinese made stuff peddled here, and so are we, importing from the UK with booster surface pumps etc. The tank will be 10m x 10m x 4m - we figure given all the limitations we will service 6 small resorts, keep locals in water and maybe have lots to spare. There doesn't seem to be any shortage of folks asking us to supply them. This years Drought has been really tough here. Submersible pumps are not easy to extract if they break down, so I have one on a 5 year warranty. The bit to look out for is that if you compromise this toward a surface jet pump you will get water, albeit at lower water volume. But jet pumps are easily fixed/replaced. If there are wells nearby using submersible pumps they will 'trump' a jet pump, sucking water away from your surface pump.

In terms of borehole specs, we had a 5" borehole, 4" and 3" casings for a 3" submersible pump. The bit I can contribute is that Polaris in town (Dumaguete) will charge P20k for their bod to come out to fit your pump if you are short on the know how - and I am very short on that!

The drilling was expected to take 2-3 months, but as everyone was hopping up and down excitedly 2 weeks into the project as the earth/stone lifted was wet and not too compacted, they predicted water very soon. They were right, they hit the first water table at 160feet after a month. They finished the drilling 2 weeks later. The contractor is doing the well cleaning with a hired compressor tomorrow.

If you need to know anything more, pm me, I'll ask the less technically challenged, and feedback to you.

cheers,
