→‎Construction, operations and maintenance

# Cover in mortar or cement to waterproof it.

# About 10cm above the ground, another outlet pipe is set, if the cistern becomes too full.

~~# Cover with a net to prevent insects from entering the tank.~~

# Cover the walls of the cistern in mud cakes, and 2 layers of cement white wash. The walls should not be too thick or they will crack.

# Build an arch-shaped cover by lying cement on a mold of mud hill covered in plastic. The thickness of the cover depends on the diameter. A 1m wide cover should be about 5cm thick.

# Install the EMAS pump. Its pipe is set in a larger stiff guide pipe, which reaches down to the bottom of the cistern and is fixed in place using cement.

# Cover the guide pipe with a waterproof stopper. Use a knife to perforate this with a small hole for water.

# Cover with a net to prevent insects from entering the tank.
