Trémolet Consulting is a consultancy specialising in water and sanitation economics, which has been providing advisory and research services to governments, international organisations and academic institutions since 2004. The firm specialises in reviewing existing financial policies, to evaluate the effectiveness of public spending, tariff structures and subsidy schemes. We are also involved in developing innovative tools for financing access to water and sanitation, such as output-based aid, micro-finance or smart tariffs. We are focused on using economic-based approaches (such as cost-benefit analysis) and instruments (such as water markets). The firm’s expertise has fed into the design and implementation of major water and sanitation projects around the world.
