Dario Posted May 22, 2019 Share Posted May 22, 2019 Hi everyone, we live in a small rural Isaan village in northern Surin province. Our village has a water cleaning system and every house is connected to the water supply. Even though after having already had yellow water and the puyai had received 200'000 Baht to renew the system, we have again terribly dirty water. The water looks yellow like piss, sorry for this word. The nearby temple abbot had a team to drill an artesian well 35+ meters deep. The water comes out quite clean, but the next morning the water is again dirty. I wonder why? People in our village have complained countless times to the puyai baan, but complaints bring nothing. The water remains dirty. The problem is also washing clothes. We have lots of white clothes, some expensive like our daughters Nike tennis wear, all which suffer tremendously. Having a 2'000 l water tank doesn't help. The dirty water goes in there as dirty as it comes from the street and feeds our hot water washing machine. I appeal to my fellow TV members. What can we do? Any constructive help is very much appreciated Link to comment Share on other sites More sharing options...

bankruatsteve Posted May 22, 2019 Share Posted May 22, 2019 Has anybody determined what is causing the issue? If it's just clay sediment, that is easy to filter but the filters need constant replacement. Link to comment Share on other sites More sharing options...

Most likely it's sediment that causes the problem. For a start you can try/test the cheap sediment filter cartridges. Do you have a pump attached after the tank?

Yes, a strong pump is attached after the tank. Could you recommend us what kind of filter to buy, I guess there are so many to choose from. HomePro is only about 70 km away from our home.

VocalNeal Posted May 22, 2019 Share Posted May 22, 2019 Not probably piratical space-wise but the late King recommended gravity fed sand and gravel filters. Either on this forum or "the other one" there is a guy with a settling basin on top of his car port !! Link to comment Share on other sites More sharing options...
KhunBENQ Posted May 22, 2019 Share Posted May 22, 2019 Put a filter between tank outlet and pump. Can be one or two stage. Typical housings are for 10 inch cartridges. Highly recommended to buy housings and filter cartridges online. Prices at hardware shops can be silly exaggerated. Cheapest I got was 22 Baht for 5 micron cartridge and 27 Baht for 1 micron (ordered in 50 piece packages) Since we have our own well the consumption has gone down much. Need to change the cartridge only about every month or so. With the village water is was dirty after a few days.

If you put a glass/jug of the dirty water aside does it eventually go clear? This will give some idea of what the problem is. Link to comment Share on other sites More sharing options...

We have a large water bucket with lid on top in the bathroom, When we put dirty water inside, after a day or two, three it gets clear and the dirt settles on the ground.

55Jay Posted May 22, 2019 Share Posted May 22, 2019 Same problem when we lived outside the city in a village, and even now, in a moo baan on the outskirts of the city. I put in one of those large cylinder filters like the one in photo below, on the right. Placed between the tank discharge and the house pump suction side. It has sand, gravel and charcoal inside. About 9,000 installed (a few years ago), then about 2,700 for them to come once a year and change the filter materials. It does the job, water in the house "looks" good, no bits or tinting but we still don't consume or cook with it. We don't even rinse with it after brushing teeth. Bottled. Mine has a maintenance lever on top to back flush the canister, which I do every now and then. Link to comment Share on other sites More sharing options...

LOL. Reminds me of my first trip to Kathmandu. Hotel put me in the big "suite", nice, but the maids overlooked the toilet - still had urine in it. So I flushed and walked away, no biggie.

FWIW you can completely avoid the problems associated with having to change your filters as often as you will need to. It's virtually certain that you have clay or similar content in your water. When the neighbours come round to us they are amazed that our water is crystal clean. We are using exactly the same supply as they are. The difference is that we have three large tanks that the village water feeds into before it's pumped into our ready use tank. So any solid impurities have time to settle out. The actual reason for the tanks are as a reserve supply but they incidentally work perfectly as setting tanks. So add a second tank, feed your current tank from that and the majority of your problems will be gone. You can add a filter to that system (after the pump not before) if it still isn't clear enough. Just add a filter and you will be changing cartridges very often as you have so much suspended matter in the water. Link to comment Share on other sites More sharing options...

Example picture for a two stage filter: A common mistake people make is to put filters between the tank outlet and pump suction. Most filters, cartridge, resin, mesh, etc are designed to be 'pushed' through. The filter(s) should go either before the tank or after the pump delivery. Clogging filters on the pump suction side will cause the pump to cavitate. A pump is designed to produce pressure so clogging filters placed downstream of the pump will not cause damage. Plus, if you don't install gauges or a differential gauge at the filter you'll still be able to tell when the filters need cleaning/changing as your water flow will decrease.

No, just over flow first tank to the second and second to 3rd. You will require ball cock on the first tank to stop overfilling (as normal) PS, don't connect via the bottom of the tanks.

sometimewoodworker Posted May 22, 2019 Share Posted May 22, 2019 1 hour ago, Dario said: Interesting! Do you need an additional pump between your tanks? If your tanks are on the same level as my 3 storage tanks are then you do not need a pump between them, as mine are configured as storage not specifically as settling tanks I have just linked them at thr bottom with isolator valves and drain valves the tank at the back is fed by the village supply as our setup has a tank at about 6 metres above these that is our current use tank we have a float switch controlled cheap pump to supply it from these tanks if the village supply is cut or low pressure. Though most of the time the pressure is enough to fill it controlled by a ball float valve If we are getting dirty water from the village I can easily (well not very easily but simply) draw only from the storage tanks and pump up to the main tank from them. your setup would be much more simple village sypply feading one tank with a float valve control, that feeds a second tank either at the top or bottom and your pump draws from the second tank (optionally pushing through a filter never sucking through one) and feeds your house.

That confirms the color issue is sediment and quite efficiently removed by filters. Before I installed a bore and pump we had same issue. Then we had a 3 stage cartridge system. In the first two I used the 5 micron followed by the 1 micron and in the 3rd a carbon. Problem was that the filters clogged quickly. To offset the cost of constant replacement I resorted to "peeling the filters a few times and putting another 1 micron in place of the carbon. The water was clear but never did I trust it for more than washing laundry etc. due to concerns sediment filters do nothing to remove chemical pollutants. Nearby a German expat has used to sand tower system mentioned plus a reverse osmosis system which feeds into a large stainless steel tank. He drinks that water with no issues. There are many options but the drawback to small systems is the capacity for household general consumption. My eventual choice was to go to a deep bore which luckily is clean but has a moderate lime content. No problem for general household use apart from lime scaling in the toilets and showers. But I still buy drinking water. Link to comment Share on other sites More sharing options...

And as written, prices at hardware stores are often inflated. I order my stuff from a specialized seller at Laem Chabang. But there is no English version of the website, so maybe not the best choice for you. I have browsed Lazada and if you look carefully you find acceptable prices. Searching for filter housing: https://www.lazada.co.th/catalog/?q=filter+housing reveals this complete 2-stage set: https://www.lazada.co.th/products/2-hidex-filter-housing-2-stage-i297054008-s506344013.html Hard to tell whether you should try with a single cartridge and see how it works?

KhunBENQ Posted May 22, 2019 Share Posted May 22, 2019 For comparison. At the Thai shop (www.duan-daw.com) a single housing is 320 Baht (*2 = 640). Add a plastic wrench and two brackets and end with about 760 Baht. 5 micron cartridge 22 Baht. 1 micron cartridge 27 Baht. Some "PVC plumping" and adapters might be necessary.

Maybe I don't run into the problem because our tank outlet is some 7m above ground/filter. But your advice sounds plausible. I would then put the filter after the pump.

a10ams Posted May 22, 2019 Share Posted May 22, 2019 Is drilling your own well on your land an option? It's a lot cheaper than you would think. Ours is unfiltered and is crystal clear. Link to comment Share on other sites More sharing options...
Dario Posted May 22, 2019 Author Share Posted May 22, 2019 I feel overwhelmed by all the advice and help I get in this thread! Thanks so much to every contributor. To the woodworker: thanks for all the pictures. I think I'll go for your solution. I'll buy another 1'000 L water tank at HomePro (link to the tank) and have them connected. and can store together a total of 2'050 litres of water at the same time. I don't like the idea of stocking lots of replacement filters and change them every week. My wife just said that the pump (a 240W Hitachi) has just given up again, electrician will come tomorrow.

shaemus Posted May 22, 2019 Share Posted May 22, 2019 @Dario I have been in the same situation. I have just installed a sand media filter and a carbon filter then I go into 20" filters from 10microns to 5 to 1. Save yourself a 70km trip. Go to www.duan-daw.com Ideally you could buy another rank and use that as a settling tank. I have used filters for a while put when the village water people decide to back flush there systems they put the bad water back into the system and it wipes out the filter cartridges. If you have cartridges alone you will be changing them quite regularly and allthough cheep, the cost does add up. I can Send you pics if you want of my system. PM me if you want to chat.

If it failed due to the sediment, then you should consider options to filter (or settle) before the main holding tank. Link to comment Share on other sites More sharing options...
