About Salone Water Security

Sierra Leone is well-watered and is now utilising its water resources for economic and social benefits. However the perceived abundance of Sierra Leone water resources should not give cause for complacency.

No one knows with absolute certainty how much water is available for the nations future growth and prosperity. With a growing population, expanding industry (particularly mining and commercial agriculture) and poor levels of water supply coverage, it is important that water resources are monitored and managed robustly and effective regulation is introduced












The National Water Resources Management Agency (NWRMA) has the mandate to manage and safeguard water resources at local, national and transboundary in Sierra Leone. The Ministry is also responsible for supporting the establishment of a regulator termed the National Water Resources Management Agency. Our purpose is to support the sustainable management of water resources. We also contribute to safeguarding domestic water supplies and work with industry to help them understand their environmental responsibilities. Our aim is to monitor, understand and report on the state of water resources, promote the importance of managing water resources, enforce water resources law and support the delivery of effective regulation. To that end we focus on the areas where we believe we can have the greatest impact.

Sierra Leone’s water resources monitoring infrastructure was largely destroyed during the decade long Civil War (1991 – 2002). Our activity is targeted at building experience and expertise in water resources management and managing water locally to solve real water-related problems and issues. We are leading and coordinating the (re) establishment of hydrological monitoring activities. We do this by working with multiple and diverse organisations who have an interest in hydrological data.  We recognise the value of community-based water resources management, with communities and schools actively engaging in collecting hydrological data. We use data to inform our decision-making for both planning purposes and for enforcing national regulations.











The Salone Water Security website is Sierra Leone’s focal point for national policies, strategies, legislation and regulation. It is also a repository for hydrological (rainfall, surface water and groundwater) data. The National Water Resources Management Agency collates, quality controls, archives and publishes hydrometric data from gauging station networks across Sierra Leone.
