New Septic Tank Needed. Advice please.

Recommended Posts

Been using the concrete rings that were installed when wifey was first building her house. She was on a premium, and so was only able to install it 4 rings deep. This means that we have to call out the 'turd sucker' more often than I would like. At 400 baht every time, it mounts up.

 

Anyway, there are only the 2 of us now, 2 sons off to Uni (hurrah) and so am considering the Vavo 8oo litre or the 1000 litre. See here https://www.globalhouse.co.th/catalog/catagory/700/1

 

Garden at back of house is about 30 ft X 40 ft - I know nothing about septic tanks, but should I get additional pipes installed that take liquids away from the tank, to allow it to spread through the yard. ( Apologies if this makes no sense. I just read something like this somewhere)

 

Anyway, any advice, help, criticism is very much appreciated. 🙂

What do you do with gray water from shower and sinks?  If have drainage system tank can feed into that.  If using rings there should be two tanks - one for toilets and second for overflow liquids from below top of first tank and then drainage from second ring tank.  If working right you should not have to pump out more than maybe once a decade.  We pumped two plastic tanks today at 500 each here in Bangkok (government price) but they have been is use 22 and 20 years (the 22 year one needed pump out.  Also have a double ring system made when house build in 1975 which was only pumped to allow new drain system about 20 years ago.  Am sure others will help you and suspect youtube will have video.  Remember plastic tanks float and it getting into rainy season so be sure to fill with water.

 As you noticed the septic tank you are thinking of buying, has two pipes, an entrance pipe and an exit pipe.

So it needs to be first in line. The waste will exit the house, enter the "VAVO" sink yo the bottom , liquid will float on the top. and exit from the other pipe . where it would go to leach field  to evaporate or be absorbed by the ground if you had the room. I dont know what your 30x40ft yard looks like but it is probably of inadequate size, soil condition and sun penetration . So your other option would be a secondary set of rings , perforated and open to the bottom, with some gravel and sand  under it and around the sides where the exited liquid will be deposited to be absorbed my the ground

If The rings you have now are far enough from the house, you might be able to install the "VAVO" first and then connect to your existing "Ring" tanks. But if it is only the two of you and and they fill up often then you might have a problem of them being inadequately constructed ans get filed up with either rain or ground water. or dont have holes, and the bottom is so saturated that it doesn't allow the liquid to be absorbed by the ground. 

Also consider having, shower, laundry, and kitchen sink water redirected to  a separate ring system , that in it's self might fix the problem.

Them cess tanks will be fine you just have to make sure it's installed correctly.

In 18 years no tanks like today in our area so our properly purpose built cess pit has never needed a "A turd sucker" I was glad at the time to be here when it was built, for obvious reasons.

No they are not fine, cesspits are illegal in the countries we come from for good reasons. In the 21st century man can do better than dig a hole in the ground and dump their waste in it. A true septic system with subterranean drain field and plantings is far superior and environmentally sound. Polluting the ground water with turds and relying on turd trucks trolling the villages honking their horns looking for their next victim is such a ridiculous system. God this world has a long way to go.

Your way too serious for me, until a nationwide system is built cesspit pits are the only way. 

If you wanna go and do your business in the woods go ahead.

No, proper septic tanks are the way to go, not concrete ring cesspits. All your concrete rings do is save you the trouble of digging a hole for "your business".

Haven't a clue what your on about, in my village there is rainwater runaways only, what do you want me to do when I built my house construct a properly designed cess pit at the time, or just send my house <deleted> to the rain runaways.

Are you a builder. ?

You do know what a septic tank is, don't you ? What do they have to do with rainwater runaways ? Septic tanks are connected to a leach field, for the treated overflow, not the village drainage system. Cesspits are just a hole full of you-know-what polluting the groundwater.

We are trying to tell you there is nothing connected to the village. Septic systems have no outlet. They are fully contained in your yard. They make sense for any house anywhere, cesspits should never be used. A cesspit is a pile of turds where no waste treatment happens and concentrated waste leaches into the ground and pollutes ground water and trucks come to pump it when it overflows periodically and eventually gums up and a new one needs dug. A septic tank has a sealed bottom and treats the waste. When treated effluent makes its way out the tank much more treatment then occurs in the drain field. Finally plantings pull all the nitrogen and nutrients out of a widely dispersed area. Think of it as recycling rather than littering. The smart choice.

My apologies guys, thanks for that, a misunderstanding of words on my part.

There all Cesspits to me 😁 because there's no local govt sewerage system.

We had a brick built one constructed with outgoing filtering pipes.

 

In my opening I was trying to say make sure a tank or rings is installed correctly without going into detail.

In our village there many houses ( well old wooden or concrete shacks is a better description ) that just have had holes dug for toilet use.

 

Many places if people get to afford it have septic tanks as replacement I can't see how they can make suitable absorption area they haven't got the room and I guess they don't bother.

Just remember that rings are no substitute for what goes on inside a sealed septic tank chamber.

A drain field doesn't necessarily take much room. Just a shallow meter wide trench of suitable length. And then you cover it and it becomes indistinguishable from the rest of the yard, save for plantings around it being a lot greener than elsewhere.

They perform the same function in the same way if properly installed.  You have two sets of rings and drain/vent - a normal septic system.

Wiki covers the varying use of the word cesspit quite well.

 

Cesspit is a term with various meanings. It is used to describe either an underground holding tank or a soak pit. It can be used for the temporary collection and storage of feces, excreta or fecal sludge as part of an on-site sanitation system and has some similarities with septic tanks or with soak pits.


Pit latrine would be best to describe a simple turd collecting hole polluting ground water.


There are many septic tank arrangements in Thailand from simple open bottom tanks through to multi tank treatment with soak away or connection to the street drainage system.
