- The tank should be close to the area of cultivation to ensure ease of irrigation.
- The tank should not be in close proximity to the house or to paths/roadways as it is possible for children and even negligent adults to fall in. Construct a fence around the tank.
- It is not advisable to obstruct patterns of the natural flow of water as there is a possibility of mud and other waste getting into the tank. (The mud filters function only when the water flows directly through them).
- Clear the selected land thoroughly. Flattening the land is important for ease of taking measurements.
- Determine the quantity of water required for irrigation purposes.
- The tank should not be more than 1.75m in depth in order to withstand the pressure of the water. Low depth makes cleaning and use of the tank easier.
- The tank should have a slope of about one foot from the periphery to the middle of the tank.
- Various waste items are present in flowing water. Mud, sand, and gravel deposits in the tank will lessen the quantity of water that can be stored in the tank. Therefore, mud-filters are used as a simple method of reducing the flow of waste items into the tank.
