Selection of the size of the reserve water tank

Water reserves must be calculated from the amount of 1 resident: 200 liters of water per day, for example, 2 residents should use a 400 liter water reserve tank. If it is an area where water stops flowing frequently, it should be reserved in the event that water stops flowing for 1 day. It will use a water reserve tank of 800 liters, etc.

bile duct work

Water pipe work, main pipe, water supply Use a PVC pipe size 3/8 or 1 inch (depending on the water supply pipe of the pump). As for the spot supply pipe, use a 2 inch PVC pipe size will help the water flow stronger, no problem with showering and water flowing. not strong

Residential mounted water heaters are recommended to use a constant pressure water pump. (Square tank type) will make good use of the water heater, stable water flow. not strong

*** for general work Can be used as a round tank It is recommended to buy a wattage of 50 W per 1 point according to usage, which in the specification indicates how many points can be used simultaneously where the water does not flow down

sewer pipe work

In the bathroom sewer work, use PVC pipe, floor 5, size 2 inches. PVC S Trap pipe should be installed to prevent sewer smell back into it. make the bathroom smell

For rainwater drainage work, use PVC pipe, class 5, size 3-4 inches, choose according to the width of the roof and the gutters must be related.

Bathroom drains and rainwater drains to be connected to the water well to go out into the pipe. Drain public sewage or into a large seepage.

air duct treatment system

Ventilation pipe for treatment system: use 1 inch PVC pipe, installed at the height of the upper beam or to the ceiling (depending on suitability) to make the work more neat, paint the PVC pipe with galvanized steel paint. will adhere well without peeling

treatment system work

There are two types of treatment systems:

  • Cement wells that are commonly used have Diameter 1 meter / 1.20 meters, height cm. will be used as armor ponds, seepage ponds, armor ponds and seepage ponds should have a capacity of not less than 1.5 cubic meters or use about 3 rings or more per 1 type

For example, 3 circles of 1.20 m. armor wells and 1.20 m. 3 circles of seepages are used.

The armored pit must be poured onto the ground of the armored pit and plastered around it so that no water can seep out for the sediment and water to rest before going out to the seepage which is not plastered and Drill holes to allow water to drain into the ground. The standard seepage should support the bottom of the well and the side of the well with broken bricks and coal inside. to filter the smell

  • Ready-made treatment tanks of 800-1200 liters for residential applications. Depending on the number of people who live and use In modern construction, prefabricated treatment tanks are used instead of armored wells, which are more convenient and meet legal standards.

For a knock-down house or building a house with a size of 800 liters is enough for 2-4 residents.

Both the armored pond and the finished treatment tank should be filled with EM. microorganisms to help speed up the decomposition process, reduce odor, and complete the treatment system faster.

Examples of treatment systems using 800 liters of prefabricated treatment tanks and sewer pipes into seepage ponds

*** Able to connect to sewer pipes, treatment tanks without going through seepage ponds in the case of a manhole that connects the pipe to the public sewerage nearby

*** The use of finished treatment tanks should enter microorganisms to speed up the decomposition process

Caution

We should dig the treatment system 1-1.2 meters away from the toilet to protect the tank. Treatment is not to be too close to the foundation. Digging near makes the soil in that area loose, causing the house to collapse. especially in the rainy season

Digging a treatment system or spreading foundation requires hiring a small macro to dig in the provinces. There is a service fee at 800-1,000 baht per hour.

Sewer work / manhole / seepage.

***In the case of a project with multiple residences There will be a problem with drainage, therefore, drainage pipes and manholes should be made every 6 meters to connect the pipes to the public sewer or, if not, make a large seepage to allow water to seep into the ground.

Tips : The seepage can remove the fiber cement residue left over. Put the bottom of the well and beside the well so that the water can seep in easily. It is a use of the useless waste materials to benefit as well.
