Graph theory spectral methods have been applied in various fields to optimise resource allocation. In water-resource management, these techniques can enhance efficiency and sustainability. This article focuses on applying graph theory for optimal allocation of water resources in Kenya. Spectral methods of graph theory will be employed to model the water distribution network, allowing for the calculation of eigenvalues and eigenvectors that reflect system behaviour. Condition-number analysis will assess sensitivity and stability of these solutions. The methodology will be applied to a hypothetical but realistic network in Kenya. The spectral method revealed a significant reduction in transmission loss compared to traditional allocation methods, highlighting its potential for enhancing water distribution efficiency. Graph theory spectral methods and condition-number analysis offer promising tools for optimising water resource allocation in Kenya. Further research is needed to validate these findings with real-world data. The developed method should be tested on actual water networks in Kenya, followed by public engagement to implement the recommended solutions effectively.
