APPENDIX 5 CONSTRUCTION OF EXCAVATED TANKS, TURKEYS' NESTS AND MODIFIED WATERHOLES Assuming preliminary investigations (Appendix 4) have shown the suitability of a specific site for a specific structure then construction can be begin. No matter how good the design poor construction methods can lead to a less than perfect structure. Excavated Tanks The site is first cleared of vegetation and the, planned tank is laid out on the ground using marker pegs. Excavation is commonly carried out using scrapers or bulldozers. If the tank is in an area with some slope (say greater than 1 in 100) excavated material can be used to construct bunds around three sides of the excavation to increase storage. The bund should have a minimum berm width of 5 m (Figure 4). Topsoil, with potential for leakage must be removed down to an impervious layer before the bund is built, and compaction should be undertaken using the available machinery (the ideal time to achieve optimum compaction is early in the Dry when soils are still slightly moist). Three sides of the tank are excavated with a slope of 1 in 3, and flow enters the tank through the side with a mild slope as low as of 1 in 10. The inflow side may be rubble packed to prevent erosion. Where the excavation is in shale, with little chance of erosion, the inlet batter may be increased to 1 in 4 to decrease the volume of material to be removed. The shale has been excavated in the past using a D6 sized bulldozer with rippers. The recommended slopes allow for machinery to enter the tank, excavate, turn and exit with ease. For offstream excavated tanks catch drains can be constructed, eg. using a tilted grader blade, to direct an increased volume of sheet flow towards the tank. Turkeys' Nests The current design and construction techniques for turkeys' nests are adequate although special attention should be paid to: removal of leaky topsoil from the base before construction; the selection of a non - dispersive soil construction material (Appendix 4); compaction at optimum moisture content. This could
