Although water is an abundant resource, climate change is affecting the hydrological cycle. According to scenarios done by the Meteorological National Institute using PRECIS regional model, an important rainfall reduction with risk of droughts is expected on the Pacific Coast watersheds and the North, while an increase of rainfall with risk of floods is expected on the Caribbean Coast watersheds.
Costa Rica’s efforts to meet international agreements regarding mitigation and adaptation to climate change have been undeniable. The strong ecosystem conservation agenda of the country has significantly contributed to making climate actions more robust.
This manual provides a step-by-step guide on development and implementation DEWATS in developing countries of the region with a set of financial schemes, market opportunities, investment and potential impacts.
The document focuses on identifying the economic, financial and environmental benefits of wastewater recycling from the perspective of public spending. Also provides information on the evolution and current practices of wastewater recycling internationally and the international and national regulatory and policy frameworks that guide wastewater recycling. It presents possible strategies for city and state planners and policy makers to initiate the discourse on wastewater recycling and reuse.

The Roadmap to a Low-Carbon Urban Water Utility presents utility managers with an approach to address their most pressing challenges, while reducing carbon emissions through
measures that either have a return on investment through energy or water savings, or that correspond to planned investments as part of the asset management plan to maintain or improve their services. Utilities adopting this approach are contributing to a carbon-neutral future, by instigating a change of mind-set, not only in urban water management but also by inspiring all other urban services through sharing the risks and the urgency to act to avoid aggravated impacts of climate change, of which water utilities are among the first victims: water scarcity, flooding and deteriorated water quality
Performance Evaluation of the “Pump as Turbine” Based Micro Hydro Project in KINKO Village, Tanzania
Microturbines installed on drinking water supply network allow converting the hydraulic potential energy loss resulting from this hydraulic design into electrical energy. The drinking water treatment plant of SUPER RIMIEZ is located higher than the customers leading to an excess pressure (>17 bars) at domestic network inlets. Installation of 4 micro-turbines on drinking water supply network: 4.5 million kWh/y generated.
