Not every building in a dacha village can be accessed by a sewer truck, due to very dense buildings and the presence of an area cultivated for crops, and waste always needs to be drained somewhere. Everything is clear with the toilet: a wooden stall with a pit at the bottom. What about waste such as water from laundry, hand washing or washing dishes? Draining it into the garden is fraught with unpleasant consequences for the harvest, due to the chemicals it contains from detergents and powders. Even ordinary grass, resistant to any kind of pollution, turns yellow and dies from it. Pouring into the toilet is also not an option. So we need to dig a septic tank!
Will need
- Two hundred liter barrel (metal or plastic).
- Drill.
- Any strong boards.
- Nails.
- Hammer with hacksaw.
- Shovel.
- Coal for barbecue (a couple of large bags).
- Ruberoid.
- A cover for a septic tank (in my version, this is a door along with the front wall from a broken washing machine).
Making a septic tank
The septic tank will have a through bottom so that there is no need to pump it out. Earth is an excellent natural filter for liquid waste with a small and not too dangerous content of chemicals, such as solutions of washing powders or detergents.This structure will not harm nature in any way; almost all of this chemistry will be filtered into coal and accumulated in one place, without poisoning nearby lands or spoiling your harvest.
So, to begin with, using a drill, we drill more holes with a diameter of about ten millimeters in the bottom of the barrel. With a frequency of approximately two holes per square decimeter. The bigger, the better. If the barrel is plastic, then you can simply burn it with a hot rod. Now the most time-consuming part of the job is digging the hole. The hole should be dug ten to fifteen centimeters deeper than the barrel, taking into account the carbon filter. After the pit is ready, pour the prepared coal into the bottom of the pit.
It is advisable to crush it into smaller pieces before doing this. We place a barrel on the coal.
We fill the gaps between the barrel and the ground with sand, tamping it carefully with the handle of a shovel, or something like that.
Next, you need to build a frame of boards, which should be placed on top of the barrel. We cover the frame with a board, cover it with roofing felt and fasten it with a stapler, leaving a hole for the lid. We will fasten the frame over the barrel to thick boards driven into the ground, impregnated with an antifungal oil composition.
If you or someone you know has a broken washing machine that has not yet been scrapped or sent to a landfill, use a screwdriver, a grinder and safety glasses to separate the front wall and door from it. This is not difficult - the metal there is not very thick. Saw off all the excess and protruding parts from it, drill holes around the perimeter of this wall, in ten centimeter increments, and nail (or screw) it in place of the lid. The result is a very convenient design.
There is no smell and, most importantly, no one will step there or fall through. In the absence of such a door, put together a plank door. Screw a strip of thick rubber to it on one side, which will replace the hinges, and a latch on the other. That's basically it. You can use it. Also, such a septic tank is quite suitable for a bathhouse or shower stall. This is quite enough for the summer season. And to avoid silting at the bottom of the septic tank, do not pour anything into it except washing, dishwashing and other liquid chemical waste.
