Water tank in village

Recommended Posts

How much do you think it would cost to buy and fit a simple above ground water tank and pump etc for a small village family house? It is already connected to erratic mains water, but at a low pressure etc.

 

What parts are needed, I assume a water tank (Blue thing) and an automatic pump?

 

Thanks for advice

Although I understand the algae possibiity above, we have a standard blue tank outside. To my way of thinking, we do not have an algae problem because the daily through put of water, washing clothes/dishes, 4 people showering 3 times a day, watering cattle, occasionally filling the kids plastic swimming pool, flushing toilet, forgetting to turn off the pump to the tank tap, the pump filling the tank past overflow for a while 😃, probably refills the tank with fresh water on average 2 - 3 times a day - We have had a blue tank for about 5 years now.

Does that Tank get direct sunlight ??

 

We had one and it got direct sunlight, when we came back from a week away, we opened the tank as the water was smelling and what we saw was a thick layer of algae floating on top, we changed the tank for a so called "food safe" tank and never had a problem since.

 

It could also be that your mains has enough chlorine in it to kill the algae ?

Yes tank gets direct sunlight, we pump from a bore so no chlorine, I fully accept that if there are going to be long periods where the water is not continually flowing your suggestion is good.

Fail to see how having a COVERED water tank, wether 'food grade' or not (plastic or stainless) would produce water with algae. Algae needs direct sunlight (like plants) to grow, if the lid is closed that doesn't happen. It cant happen. Ive never had an algae problem in a water tank and I've had them in direct sunlight.

I am only talking about the Cheapo Blue Tanks, they let sunlight straight through !!

 

Edit: I doubt it that I still have the pictures as it was a couple of years ago, but it was a thick layer of algae (green gunk) what was floating on top of the water

On the cheap side, a tank like this 1000l

This type of float valve for the mains water supply, to keep the tank topped up;

And this automatic pressure pump:

This is about the most entry level you can get unless you want to get super cheap and I wouldnt recommend going any cheaper.

Ive never had that problem and Ive had cheap blue ones in direct sunlight. Now if the lid got left off, maybe.

Very easy to do.

 

you need to get a small tank, 1- 1500 liters should do, unless you want the capacity to store, vs maintain a constant flow with increased pressure (5-7000... better quality.)

 

the tank should be placed on a very well prepared (flat) surface... a concrete pad is good, but slabs will do, on a prepared bed (500-3000)

 

break into the mains supply and plumb that into the tank, with a ball type float valve to open and close the mains supply line (500)

 

then you need to install a pump from the bottom tank outlet, plumbed back into the old mains supply to the house (4000)

 

i would recommend installing an inline cartridge water filter somewhere between the pump and the house, as well. You would be amazed at how quickly they clog up with slimy green goop (2000)

 

Quality pvc pipe and quality glue should be used, and stick valves in wherever you think they might be handy, for future take off points or maintenance (1-2000)

 

I installed electronic pump switch’s operating off volume indicators, with low level light indicators etc, to mine, but they are a convenience more than anything, in case I wish to use tanker water supply, and I have 4000 liter storage capacity on site. (Although I recommend one for turning off the pump, in case your water level drops too low for any reason ( mains supply fault) (2000 baht)

 

obviously you will need an electrician to wire up your pump

 

so... on the cheap.... less than 15000 baht.... decent tank and quality pump etc.... 20000 baht plus.

 

mmm... your op said mains supply... secondary post says bore (not that the actual form of supply matters, but you might need to install an on/off switch on the tank “full” side, vs a simple float valve on the supply line, to protect the bore pump, although some models stop pumping at a certain pressure, which is fine, unless a line starts leaking) another 2000

 

if using a bore, consider using alum to control solids, and also consider adding small amounts of chlorine to the system yourself. Alum won’t hurt you if drinking, if you do that vs bottled water, nor will small amounts of chlorine, but judging the amount might take a bit of practice.... 100g to 1000 l maybe.... if you smell chlorine coming from the tap... oops... use less.

 

good luck.

Got to say we buy our drinking water now, cheap, and it is delivered, empties collected, saves messing around trying to make the bore water drinkable, must be pretty good though, cows take no hurt, but safer and less hassle to buy water in.

I did this for so long, and finally got tired of it and bought a small reverse osmosis system for my drinking water at home and it was the best decision ive made in a long time. I got mine when they were about 6-7k baht. Now they are about 3-4k. Its the same system that most people use to purify water. I use it for drinking water only, filling up old water bottles and putting them in the fridge. Been drinking bore water at the house for a couple years now.
