Prepare A Water Tank. Get Ready for Drought

Because “drinking water” is essential, it’s the first thing needed for living especially in a catastrophic situation. Therefore, keeping the water hoarding sufficient is necessary in case of no water or drought. Like Thai houses in the past, they had big earthen jars for water hoarding lined up in their houses. But today, we changed from using big earthen jars to a big water tank. Simply put the water inside and we have water to use for a long time. Which water tank size is suitable and sufficient for members in each family? Let’s get to know the different types of water tanks to be suitable for your family.

Which Tank Size Suits Your Family? At an average, one person uses water about 200 liters/day/person, for calculating the water tank size: calculate from the amount of members in the house multiply with water consumption per day. (the result should be multiplied again by 2, in case of water shortage more than 1 day). As for the tank for rain water hoarding, choose the largest size for a large space. Rain water must be stored enough for 1 year forward. Information for Water Tank Installation When you already got a water tank, you need to specify the place to install the tank. Most importantly, if you buy a big tank, make sure that you can fit it into your house. See whether you can move it through your gate.
	The tank must be installed straight from the meter into the tank with a distance of not more than 2 meters. Pump installation should not be directly exposed to the sun and rain. It should be installed at least 5 cm. away from the wall. The width of the surrounding area should be at least 10 cm wide. Make sure the upper part has enough space to open the tank lid easily. Installing the tank on the newly poured concrete floor, concrete should be at least 7 days old to carry much weight. It should be 90% tough. Or after 28 days, it can carry full weight. Install the tank in a position where the connection of the tank to the pump is convenient, unobtrusive and connect the drain at the bottom of the tank for easy cleaning. Use connectors such as PCV, brass or stainless steel size ¾ or 1 inch to make water flow faster and to prevent corrosion and rust.

The water in the tank storage should be changed every one year. If there are no emergencies, the water should be used for routine such as watering plants, car wash or cleaning. Then, put fresh water to ensure water is clean for future emergencies.
