A Registration Certificate is issued to an approved community group.
Site evaluation reports
In most cases, the Client will give the highest priority to finding sites for hand dug wells along seasonal riverbeds or in shallow ground water because they are the most cost efficient water sources. In areas without suitable riverbeds and shallow water tables, the Client may give the second priority to harvesting rainwater from roads into either small earth dams or ground tanks. Where large roofs are available, such as at schools and hospitals, the best option, although expensive, may be gutters and
Survey and design
Plan and profiles of a probed riverbed
Design drawing for a hand dug well
Design drawings are made by adapting computerized standard drawings to the specific site conditions.
MoW requires 5 sets of drawings of the probing and designs in A2 format.
MoW, WSB, WRMA and NEMA stamp and sign the drawings when they are approved. One of these copies is returned to the Client as the permit to construct the structure.
Bills of quantities
BQs are used to calculate the construction cost of structures, such as a hand dug well, in order to estimate a realistic budget, which must be part of any Project Proposal. The best method to establish the construction cost of a structure is to photocopy a BQ and give a copy of it to each of at least three contractors and 3 suppliers of materials while asking them to give a quotation. To prevent over-pricing and cheating it is important that the contractors and hard ware owners do not know who else are giving quotations. When comparing quotations it is also important to consider issues such as delivery time, delivery capacity, warranties, qualities, down payments and final payments, because the cheapest quotation may turn out to be not the cheapest after all.
