It is a common phenomenon in the urban centres of the developing nations where most houses are in deplorable conditions. The houses are overcrowded with little or no air space between them. There is no basic sanitation in the urban centres as they lack flush toilet, some of the few available flush toilets are piped into seasonal streams, most houses lack defined kitchen areas and healthy sewage disposal method. The cities lack good access roads and functional drainage system with a common practice of environmentally-unfriendly solid waste management methods that create various health challenges to urban dwellers. The aim of the study is to show how in-situ Housing method of slum rehabilitation can be applied through Public/Private Partnership to upgrade houses within a major slum area in Yenagoa. This shall be done with an agreement between the property owners, Real Estate investors and the state government. Basic Research Methodology was applied using questionnaire, direct observation and personal interview techniques to collect data. Both qualitative and quantitative techniques were applied to analyse data through the use of tables and charts. The findings in the study showed that poor housing condition seriously degrade the environmental quality of the study area. The standard of living in the area is very poor as the people lack access to decent accommodation, basic sanitation and social amenities.展开更多

The intent was to find out if frequent well failure was as a result of the aquifer not having enough transmitting capacity to sustain the huge withdrawal necessary for Eleme and its environs where demand for groundwater withdrawal is very high because Eleme axis serves as a major industrial axis of River State or whether the frequent well failure was due to inefficient well construction practice. Constant discharge pumping tests were conducted in 8 deep borehole (250 - 310 m). Data generated during the test were analysed using Cooper-Jacob’s straight line method. The calculated transmissivity of the aquifers ranged from 1324 m2/day - 5815 m2/day. These values when compared with transmissivity values elsewhere indicate that the aquifers in the study area have excellent water yielding properties, plotting within the range of “Very Good” in water transmitting capacity scale. Coefficient of permeability ranged from 13.65 m/d - 59.9 m/d. Coefficient of Storage ranged from 28.2 × 10-5 - 29.1 × 10-5 while the Specific capacities of the wells ranged from 48.75 3 - 78.13 m3/d/m. It is concluded that the deep aquifers of the Niger Delta do possess the capacity to produce and sustain large groundwater withdrawal. It is further recommended that competent drilling contractors be engaged in deep well construction in the area.展开更多
