Furthermore, public feedback has been recognized as a necessary input for integrated water resources management. Thus, public feedback regarding the state of water supply in Lagos state was harvested using stratified sampling technique, while data was analyzed using descriptive statistics. Lagos is a mega-city with annual growth rate of 5% and 21 million residents. Results show that majority of the residents believe water services should be free, and behave as such. Lagos Water Corporation (LWC) supplies 210 million gallons of water/day to the city but loses 60-83% of its production to vandalism, illegal connections and ageing infrastructure. The resultant effect is that 34% of the residents are reached with water, while 64 % use groundwater as an alternative. In Lagos Island, where water table ranges from 3-7 m, septic tanks are sited indiscriminately and saltwater intrusion is frequently reported. Thus, groundwater pollution is rife and public health is constantly at risk. Using proven examples, the paper demonstrated how repositioning LWC for sustainable production and distribution of water in Lagos could provide the cheapest, cleanest, and quickest alternative for making water available to all residents.

Twenty four years’ (1987 to 2010) wind speed data at 10 m height obtained from the Nigerian meteorological agency were employed to classify the sites wind profiles for electricity generation. The energy cost analysis of generating wind electricity from the sites was also carried out. The outcome showed that sites in Lagos and Oyo States were adequately suited for large scale generation with average wind speeds ranged between 2.9 and 5.8 m/s. Those from other sites may be suitable for small scale generation or as wind farms, with several small turbines connected together, to generate large enough wind power. The turbine matching results shows that turbines cut-in and rated wind speeds of between 2.0 and 3.0 m/s, and between 10 and 12.0 m/s respectively will be very suited to all the sites, particularly those in locations outside Lagos and Oyo States. The energy cost analysis shows that generation cost can be as low as 0.02 €/kWh and as high as 5.03/kWh, depending on the turbine model employed.
