Wastewater Usability in Abuja Municipal, Nigeria
Main Article Content
Abstract
Urbanisation in Nigeria cities has affected to a great extent the water and sanitation. The urban sprawl has increased wastewater generation whose management constitutes a great challenge in achieving urban sanitation. Abuja as a fast growing modern capital city is experiencing a high urbanisation at 3.4% growth rate without a commensurate development in its wastewater management infrastructure. This study examines the issues of wastewater utilization in Abuja, with the aim to proffer solutions to some of its challenges. The research used primary data through questionnaire method administered to 2393 households within the 10 randomly sampled districts and also secondary data on Wastewater Treatment Plants (WWTPs) capacity utilisation. The urbanisation has over stretched the existing infrastructure beyond the design capacity thereby posing an eminent threat. A study of the Wastewater Management (WWM) of 10 Districts in Abuja Municipal Area Council (AMAC) revealed the existence of a total of fifteen (15) WWTPs with a capacity of 900,000 litres per day (lpd) installed capacity Population Equivalent (PE). However, a volume of 230,000 lpd pe of the existing operational capacity is being utilised. A proportion of 29.54% of Wastewater (WW) generated is treated while 70.46% is
untreated due to underutilization and the state of disrepair of the existing treatment plants. This under utilisation capacity affects 13 out of the 15 Treatment Plants (TPs). This research urged maximum utilization, prompt funding and deployment/employment of skilled manpower. The recommendations centred on Abuja Environmental Protection Agency (AEPA) to ensure the profitability in the functionality of WWTP’s such as: WWM should integrate water supply usability and staff capacity building to its maximum stage to cope with the urban utilisation trend.
