Set an inlet and an outlet at opposite corners of the pond. To facilitate the leeches' habitat and egg-laying, some irregular stones or branches can be placed on the pond bottom. In the water, 5-8 earthen platforms should be built 20 cm above the water surface, each about 1 sq m. The pond ridge should also have an escape-prevention ditch, built with bricks, 12 cm wide and 8 cm high.
