And a shot of it, after it in it's hole on the south side of the house:






And another view from a different angle, so you can see the proximity to the house:





We obviously filled it in, so, as long as there is inventory in the tank, the water will be relatively cool. That cooler water will also help with pump suction as well.

Hi Steve. I see the tank 2000 ltr. Do they have bigger ones.

Does anyone know the expected life span of a water pump? I purchased a Hitachi 300W pump for my wife's parents house 6 years ago and it it still going strong. I purchased anotner one for our house about 3 years ago and it has given us problems off and on and I am thinking about trading it out. When I ask if there is someone who can rebuilt it, I just get blank stares.

Rick, what brand pump did you buy for you place ? I've gotten the impression that the cheaper Chinese pumps just don't hold up.

Based on what I read in some threads here, I specifically chose Mitsubishi (250W). After all the abuse it's gone through and still keeps working, I'll go with Mitsubishi if and when this one finally goes. But it will be the 300 W model.

My Mitsubishi going strong after 11 years. Other than replacing a spring on a check valve no other probs.

Google search for ถังเก็บน้ำ or ถังเก็บน้ำใต้ดิน (below ground)

Here's an above ground one at 3000 litres. The chart at the bottom shows various other sizes.

This shows various sizes (up to 6000 litres) for below ground tanks

After further work on the security wall and grading, can you spot the water tank ?

Please go troll someone else .

I have a Hitachi GX 300W pump that I bought off a friend who was also building a house and did not need it. We have had issues with our water supply in the past and now I am convinced we need to go deeper with the well. When we had it dug, I was told it was 30 meters deep, but when we pulled the PVC to clean the terminal filter, it was more like 18 meters. I would like to go minimum 30, but even deeper as long as we are digging. I just purchased a new Hitachi GX 350 Watt pump from Do Home for 9900 baht and hope that does the trick.

With my tank , once a year I take out the drain plug at the bottom and give the tank a good clean so all the heavy particles of dirt that are in the bottom of the tank are flushed out .!

Good point. Our tank was cleaned out before we installed the filter system upstream of the tank. So very little dirt gets in to the tank. Every once in a while, I'll toss in a little bleach to kill off any little critters.

Thanks Steve, i have found from company they do 3000 & 5000 ltrs. Its my intention to get 3000 ltr and collect rain water for drinking via guttering.

I know they collect rain water down under, but I don't know how you avoid bird droppings and what not from getting into the water. Also how will you keep out mozzies ? We put a mesh screen on our tank vent to keep out the little critters.

I'll be curious to see how your idea progresses.

Steve

Rick,
Our in ground 2000 l tank has a float valve that is set near the top. I think it's a standard setup. There's no level indication, other than pulling the cover off and looking inside. Which I have taught my wife's brother to do, if there's water supply problems in the house.

Baldrick,
Why don't you install a check or non-return valve in line so that you can't send water back out to the town ?

Dave,
Thanks for the explanation. I know it's a popular option down under to collect the rain water. But it sounds like you only used it for watering and gardening purposes ?

Steve

My water dilema continues. Called several drillers and all want to dig a new well instead of drilling deeper in the existing well. Does anyone else think this is strange or money gouging? Why can they not take the existing well deeper?

Right now, I am also thinking about plumbing the tank so that if my well pump has problems, I can switch to village water. I am trying to cover all scenarios to prevent running out of water. If the electric goes out, switch to gravity feed. If my well pump fails, switch to village water. Collect rain water for watering the garden. Have I missed anything?

Hi Rick, i don't know if they are available here, but in oz there several depth gauge devices which can easily be fitted to a water tank, just a float device with a gauge to show the depth of your water.

No Steve. The underground tank = drinking water. the above ground tank = house hold water. All the grey water goes into the septic system which has got a holding tank , when it reaches a certain level a pump cuts in and the water goes to inground
sprinklers to lawns etc.
