Evaluation of Sewage System Maintenance of Buildings and Its Disposal: A Case Study of Senior Staff Quarters at University of Jos Permanent Site

Abstract

Buildings consist of sewage systems which help to evacuate unwanted waste. This evacuation can also be referred to as sewage disposal. Sewage treatment also is the process of removing contaminants from wastewater, including household sewage and runoff (effluents). It includes physical, chemical and biological processes to remove physical, chemical and biological contaminants. Efficient sewage evacuation/disposal leads to effective sewage treatment. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). With suitable technology, it is possible to re-use sewage effluent for drinking water, although this is usually only done in places with limited water supplies, such as Windhoek and Singapore. All these can only be achieved by adequate sewage system maintenance /disposal. Sewage and effluent can contain a variety of human disease-causing microorganisms and parasites. Disease can be spread to humans from this material by direct contact or indirectly by consumption of contaminated food or water. The safe disposal of sewage and effluent is therefore essential to protect the health of the community. The issue of sewage disposal assumed increasing importance in the early 1970s as a result of the general concern expressed in the united states and worldwide about the wider problem of pollution of the human environment, the contamination of the atmosphere, rivers, lakes, oceans and groundwater by domestic, municipal, agricultural and industrial waste.
