Project Life Cycle Management and Reliability of Potable Water Supply Projects in Informal Settlements in Kibra Sub County, Nairobi County, Kenya.

Abstract

Access to reliable potable water in informal settlements is a persistent challenge, particularly in areas like Kibra Sub-County, Nairobi County, Kenya. Residents in these densely populated and underserved communities often struggle with inconsistent water supply, poor water quality, and inadequate infrastructure, leading to significant public health risks and compromised quality of life. The root causes of these issues are often linked to deficiencies in project life cycle management (PLCM), affecting the sustainability, execution, and planning of water supply projects. This study investigates the influence of PLCM on the reliability of potable water supply projects in Kibra's informal settlements, by focusing on the influence of each phase of the project life cycle on overall project performance of water supply projects. The study employed a descriptive survey design and targeted a sample of 339 respondents, including residents who are either involved in or affected by water supply projects in Kibra. Data were collected through structured questionnaires and analyzed using both quantitative and qualitative methods. The findings reveal that efficient project management significantly enhances the reliability of potable water projects, reducing the frequency of water shortages and improving overall accessibility for residents. Specifically, project identification accounted for 72.2% of the variability in water supply reliability, with a significant positive impact. Project planning explained 52% of the variance, demonstrating the importance of thorough planning in achieving reliable water supply. Project implementation accounted for 49% of the variance, emphasizing the need for effective execution of plans. Monitoring and evaluation, explaining 46% of the variance, highlighted the crucial role of continuous assessment in improving project outcomes. The study concludes that the adoption of comprehensive PLCM practices is essential for the successful and sustainable operation of water supply systems in informal settlements. It is recommended that stakeholders prioritize meticulous planning, continuous monitoring, and adaptive strategies to address the unique challenges of these environments, ultimately leading to a more reliable water supply projects for Kibra's residents.
