==Suitable conditions==

* The base Base of the pond needs to should be impermeable, e.g. unfissured rock or clay, in order to save costs and prevent having to find a form of lining.

* Minimize excavation – use natural or man-made topographical features, e.g. borrow pits from road construction, or sloping ground.

* Site in areas of high intensity rainfall, as this leads to high runoff, causing ponds to fill with water rather than water infiltrating into the soil.
