Water Tanks

[inthake8]

Anyone know someone who can make good onsite inground water tanks ? I've looked around at these plastic ones and they are very expensive, I'm only looking for about 10000 liters or so.

Some are made of concrete rings that you stack on top of each other. No idea bout the price. The installation is a bit touchy, ours wasn't sealed properly at the top and rainwater/groundwater would seep in. When I cleaned it, I also noticed some hairline cracks all over the inside.

I noticed Thai people have their tanks like 5 meter up in the air,

does this give a stonger flow than the waterpumps??

Or can you combine them and put the pump up there as well?

Yes, nothing like gravity to help things along.

Had a couple of guys come around to take a look at making a tank and putting it in the ground for me. Haven't see them since. How many times has this happened !!!!!!!

Do you mean that gravity in this case superseeds the pressure of the waterpump??

I wouldnt call less than £300 for a 2000 litre treated tank with a good quality high pressure pump, all installed expensive.You could get one a lot cheaper, all depends on size and quality. |I went for big and good. The higher up you put the tank the greater the flow pressure. It all depends on your needs. I have a 2 storey house with hot showers upstairs so need a good pump. A tip though, get out of HH and youll find them far cheaper! hope you get sorted, Dunc

Do you mean the higher the pressure towards the pump (from elevated tank(s)) the higher the output??

Or did you elevate your pump as well

The construction for an in ground tank should not be difficult and beyond the means of most builder types. I'm looking at building a 3x3x2 metre (18,000 litre) in ground tank out of concrete, rebar and block with a strong render on the inside. I looked at plastic/purchased options and either there's not a lot to chose from or they are very expansive for the size. 4,000 litre plastic runs about 19,000 although I am told that you can buy 4,000 litre blue plastic above ground tanks in the villages for around 3,000 but have not seen them. I reckon a good strong base out of concrete with reinforcing steel in the middle plus walls of concrete block and rebar and backfilled with concrete should do the trick and be cheaper and better than the alternatives.

Bit of info on how the Karen do it up in the mountains....Building water Tanks....

I need some as well...

incid...Not connected ...its a Thai charity....

Storing the water: info...

Once the pipes reach the village, large storage tanks are built.

These can hold up to 20,000 litres of water. The water enters the tanks through the top and continually flows throughout the year.

Each family will use around 500/600 litres per day for drinking, cooking and for hygiene. As this is a gravity fed system, the tanks have to be built at a strategic height above the village and on sufficiently firm ground to avoid subsidence. A large area is prepared with boulders and cement. Wires are put in place to support the height of the tank and strengthen the concrete.

Concrete is poured into ring moulds which makes the cylindrical shape of the storage tanks. Once dry, the ring moulds are placed on top and another layer of concrete is filled in to give it extra height.

A lid is made by folding the wires across and concreting over the top.

The water enters the tank through a gauze lined hole which gives an extra form of filtration. This is covered with a small concrete lid to allow access for cleaning.

Nothing like an underground tank and unexposed water pipes if you want to enjoy cool and refreshing showers. Elevated tank water must be piss-hot.

does your tank fill with regular community water or do you have a well

how much watt is your pump to the house?

Just had another guy come around and measure up for the water tank. He makes fiberglass tanks. we're getting him to give us a quote for a 3mx3mx2m tank. will let you know the outcome, if he comes back.

[inthake8]

Well he came back. 120000 baht, to make a fiberglass tank, dig the hole in the ground, put in the pipe work.

Sounds a bit expensive to be, as I can buy 3 x 6000 litre plastic tanks off the shelf for 90000 and I thought that was expensive.

Think I will try for a better price.

The failure point on most types of atmospheric storage tanks will be near the base, where the pressure is greatest. One approach is to make a compartmentalized / partitioned rectangular tank. I believe a 1 meter cube = 1,000 liters? If so, a 2 X 4 X 2 (deep) m would hold 16,000 liters.

I would have thought that local precast tanks might be available .. perhaps like septic tanks? If so, a sealer can be added to the exterior surfaces before burying.

Elevating a tank requires a significant structure, figuring that 1 liter of water will be 1 kg? Elevation adds pressure at the rate of about 1 PSI / 2.4 ft. If you have the landscape for a natural elevation, it is worthwhile. I believe I paid Bt 3,900 for my pump, which pumps from grade level holding tanks. And the pressure is okay.

Well, got the new concrete tank in 4 x 3 x 2 meters or 24000 liters for 48000 baht. We'll see how it works or if it falls in.
