In the beginning of this year, Valérie Audibert, partner at Phœnix, carried out two training missions to update the financial models in place with the stakeholders in the water sector in Togo and Benin. The Phœnix partners have recognized expertise in financial analysis and modeling of the sectors and operators of water, sanitation and electricity in developing countries, especially on the African continent, resulting from long practice. Over the last fifteen years, several water companies in the sub-region have decided to adopt the technico-financial simulation model developed specifically by the teams led by Valérie Audibert during studies: SONES in Senegal, ONEP in Ivory Coast, ONEA in Burkina Faso, SPEN in Niger, SONEB in Benin, SOMAPEP in Mali, TdE and SP-Eau in Togo. They trust us today to support them in updating and evolution of this decision support tool. Shared between the different actors (operators, regulators, line ministries, donors), these models have the objective to constitute a full part decision support and negotiation tools allowing strategic arbitrations in terms of coverage of the service, investment, financing and pricing. In Togo, a technico-financial model of the urban water service had been developed in 2016 during the implementation of the tariff study carried out by Valérie Audibert. In Benin, the model has been in place within SONEB for more than 10 years, and redeveloped during the project manager assistance of the Cotonou DWS project – Phase 2. Each time, it is a complete financial simulation model, projecting by 2030, the term of the Sustainable Development Goals, the water demand of all the centers of the current and future perimeter, the investment program to meet this demand and the financial statements of the companies in charge of operating and managing the infrastructure. It enables the calculation of the average price ensuring the financial balance of the companies. Phœnix is delivering a training and support series for a team of agents in the water sector using a technico-financial model. In Togo, with funding from AFD, 9 agents from the TdE – the farmer -, from SP EAU – the assets company – and from ARSE – the regulatory authority of the sector – follow training for three consecutive years. In Benin, with SONEB’s own funding, the sessions are geared towards an annual update of the model, with an increasingly complete control of the tool by the agents. These training must allow the agents to understand, master and update the model, with updating exercises in real situation.
