Appropriate treatment of wastewater before disposal into the environment or reuse is very important in the quest to protect the environment and safeguard public health. This paper investigated the performance evaluation of a waste stabilization pond (WSP) for treatment of wastewater from a tertiary institution campus located in Jos North Local Government Area of Plateau State in North Central Nigeria. The waste stabilization pond of the tertiary institution campus was designed for a wastewater flow rate of 12,945 m3/day. In order to evaluate the performance of the WSP, a model was developed following the Froude’s number dimensional analysis technique. The model was evaulated based on a wastewater flow of 0.4 m3/day. The final effluent from the maturation pond had 80 mg/L BOD, 195 mg/L COD, 75 CFU/100ml Total Coliforms, 610 mg/L Total solids, 19 mg/L Total Nitrogen, 210 mg/L Chloride, 28 mg/L Phosphate, 1.3 mg/L Ammonia and 7.0 pH. The WSP was able to achieve an overall efficiency of 77.78% reducing all quality parameters to recommended limited with exception of total nitrogen and phosphate. The implementation of this design will go along way to aid the treatment of wastewater from the campus of the university.

The characteristics of Soil is one of the major factors that affect flooding. This study therefore was carried out to assess the infiltration rates and index properties of soil within a flood-prone community of Oforachi in Kogi State, Nigeria using appropriate standard methods. Data obtained showed that the average soil infiltration rate ranges from 1.89 – 3.24 cm/hr and the maximum infiltration rate range between 6.00 – 9.00 cm/hr, while the soil antecedent moisture content was between 15.00 – 42.48 %. Soil infiltration properties classification based on hydraulic conductivity and sieve analysis show that soils within the study area combine silt and clay characteristics which has strong relationship with the persistent flood experienced in the area.
