Surinkiwi Posted June 1, 2021 Share Posted June 1, 2021 Can someone please help with what is required to set up the water supply from a 100mm bore, that is 12 metres deep, to supply a single level house. I would like to run a filter of some kind and install a 1000 to 1500 litre tank. The house has, a hot shower ,2 toilets, washing machine, tub and kitchen sink. I need to have water for the garden also that would bypass the filter system.Do I need to run two pumps? Any help would be appreciated. Link to comment Share on other sites More sharing options...
kickstart Posted June 1, 2021 Share Posted June 1, 2021 I would say, get a Mod to shift this to DIY ?. Link to comment Share on other sites More sharing options...
Crossy Posted June 2, 2021 Share Posted June 2, 2021 Yeah, DIY is probably a better forum. Moving there. 1 Link to comment Share on other sites More sharing options...
Crossy Posted June 2, 2021 Share Posted June 2, 2021 In simple terms:- Bore pump to tank (control the bore pump with a float switch). Coarse filter on the tank inlet to keep the big crunchy bits out. Automatic pressure pump tank to house. You may want another filter on the pump outlet. Maybe an RO system for drinking water. If your bore water tests as hard or with dissolved iron etc. you may need to add a specialist filter to remove same to avoid problems with water heaters and washing machines. 2 Link to comment Share on other sites More sharing options...
Bagwain Posted June 2, 2021 Share Posted June 2, 2021 (edited) Good advice from Crossy. I would also look at 2 P.O.E (Point of entry filters) after the house pump. At least one with "Eco Clear" recycled plate glass media. (See attached brochure) I have used it extensively in P.O.E & pool filters. It is brilliant for taking out metals & also very low micron filtration. If the water is hard then a secong filter with Resin to help soften the water! P.O.E filter are best after the house pump as the tanks can get contaminated! Also be mindfull of the type of "Eco Clear" you purchase. If it's coloured, then it's recycled bottle glass and not good!

IsaanAussie Posted June 2, 2021 Share Posted June 2, 2021 You might consider placing the storage tank on a stand as a means of guarding against power outages. Doesn't need to be too high to give you a good volume of gravity fed water. 1 Link to comment Share on other sites More sharing options...

Saanim Posted June 2, 2021 Share Posted June 2, 2021 Quote Can someone please help with what is required to set up the water supply from a 100mm bore, that is 12 metres deep, to supply a single level house. Actually, you can pull the water only from 9 m depth (Newton's law), and the best by a piston pump that you buy at a village hardware shop or Global House, Thai Wasadu, etc. I will attach picture and a sketch of piping with a storage tank. 1,500 L should be enough. However, you can face a problem of the water with a strong content of iron, that's quite common problem in Thailand. You can see in some villages big concrete round tanks with a shower spray on the top that should speed up oxidation of the iron. It mostly does not work anyway, the oxidation needs a longer time, the iron will clog the sand filter (that is under the shower in the tank), after 2 weeks the water flows over. If it's your case, that will need more explanation, I have spent a lot of time and developed a system that feeds my swimming pool, I can show more later. 1 Link to comment Share on other sites More sharing options...
Saanim Posted June 3, 2021 Share Posted June 3, 2021 ^ I should have added: if the bore well is 12 m deep and the water reach 8-9 m depth, then OK, it can be done as I described above, the sucking pipe PVC 1" to the piston pump. If the water level does not reach 9 m depth, then a more costly submersible pump needs to be used, inserted in the 100mm pipe. The red line in my sketch will be added - or can be foreseen - when the city water system is later available, my case after years of struggling with a strong ferrous bore water... One good precaution: the automatic pressure pump for the house demand should be wired with interruption (to the plug) by a swimmer switch supervising the lowest level in the storage tank. Once it happens that the tank is empty - emptied by a leakage or by a forgotten faucet in the house, the pump will be running without water for number of hours. If the pump luckily will survive, there is always a dirt sucked from the bottom of the tank, soiling the sand filter, its cleaning will take a lot of backwashed water. 1 Link to comment Share on other sites More sharing options...

My farm setup uses larger diameter pipes to increase flow rate. 4X1000L tanks linked together and feeding into 2" pipes. Fills a bucket in 10 seconds. Those tanks are sat on a platform 2.4 metres from the ground. 1 1 Link to comment Share on other sites More sharing options...
