Abstract
Municipal water systems in Nigeria have faced significant challenges in adoption due to various socio-economic factors. A mixed-method approach was employed, combining quantitative data analysis with qualitative interviews to assess perceptions and practices related to municipal water systems. Quasi-experimental designs were used to control for confounding variables and measure adoption rates accurately. The study identified a 15% increase in system adoption among communities that received targeted community engagement interventions compared to those without such initiatives, with confidence intervals indicating a margin of error of ±3 percentage points. Quasi-experimental designs proved effective in measuring municipal water systems adoption rates. Community engagement was found to be a key driver of increased system uptake. Further research should explore the long-term sustainability of these interventions and consider scalability across different regions of Nigeria. Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
