Abstract

This paper presents an overview about water, wastewater management and biochemical impact of sludge on soil properties in Port Harcourt, which comprises of Port Harcourt City and Obio/Akpor Local Government Areas. The main problems related to the availability of water resources and their preservation from the pollution are described. Moreover, a detailed description of the different efforts done in Port Harcourt in recent years to overcome the technical, economical and organizational problems of water and wastewater management and to catch up the considerable delay regarding sanitation and recovery of treated wastewaters has been reported too. Such as the establishment of Port Harcourt Water and Sewage Corporation with the aim of providing, regulatory, adequate water resources infrastructure and affordable water supply for the growing population and sewage treatment. The use of Sequencing Batch Reactor (SBR) method is considered as the most appropriate and suitable treatment mechanism to treat the increasing flows of domestic wastewater in Port Harcourt. However, the effluent produced were up to standard as recommended by National Environmental Standards and Regulation Enforcement Agency (NESREA) and World Bank. Also is the establishment of the usefulness of the sludge in the production of fertilizer that is use for the improvement of the soil properties to enhance high agricultural productivity. This was done through the investigation of the biochemical such as Nitrogen(N), Phosphorous(P), Potassium(K) and TOM (Total Organic Matters) levels for the test soil (2.37 mg/kg, 32.89 mg/kg, 32.15 mg/kg, and 3.12 mg/kg) respectively over the control (0.93 mg/kg, 11.09 mg/kg, 36.35 mg/kg, and 2.14 mg/kg) respectively. Zn, Pb, Ni and TOC (Total Organic Carbon) which are essential to plants and animals were also found to be significantly higher in the test soil (19.26 mg/kg, 5.71 mg/kg, 1.60 mg/kg, and 1.81 mg/kg) respectively over the control (8.62 mg/kg, 2.58 mg/kg, 0.52 mg/kg, and 1.24 mg/kg) respectively
