$ for units 1-25, while service charge is 0.5-1US $. For units 26-75, it is .75 – 1.1US $ while servicecharge is 2US $ – 10US $. For more than 75 units charge is 1.2US $ while service charge is 16US$. The above method was found to reduce wastage and more consumers were benefited. In the samecity there are community living about 2km away from the coast. Here they used ground water fordomestic purposes. Because the region is considered to possess non artesian (unconfined) aquifer, thereplenishment is by rainfall (inflow, runoff etc). The study showed the ground water depth in domesticwells ranged from 0.5m to 2.1m during the drought period and therefore the recommended wells haddiameters ranging from 1m to 1.5m. Hence it is concluded that water resource management to provideraw water to the city concerned must be cyclical and accompanied by the regular evaluation, assessmentof progress and re planning. Further local authority should strengthen the capacities of urbanmanagement, information, administration and urban design so that flood will be properly managedwithout disturbing water resource management to provide raw water required by the inhabitants ofthe cities. Authority could also convince the people the importance of conserving water by organisingawareness programme of how to use their tap water sparingly for washing and also reduce thetime of bathing by few minutes and thereby in a city of 90,000 inhabitants, the amount of water thatcould be conserved will be more. If this is practiced by the population of the world, the world willnot feel any scarcity of water and future generation will be happy. The above strategies are useful forthe surface and ground water management. The combination of population growth, environmentaldegradation, climatic change bring new challenges to water management and regulation (Ramboll2010).These challenges could be met successfully by proper urban development plans. High irrigationdemands and polluted drainage flows from agriculture mean less fresh water for drinking or industrialuse. Contaminated municipal and industrial waste water pollutes rivers and threatens ecosystems. Ifwater has to be left in a river to protect fisheries and ecosystems less can be diverted to grow crops.Therefore domestic consumers cannot waste water.40 Workshop 1: Cities in a 3-D Landscape Perspective – Hidden Risks
