During the training session, the main concepts discussed in the first part of the cycle were reviewed, focusing on the methodology for the design of tariff structures and the calculation of average costs. The importance of having an efficient tariff structure that guarantees economic and social sustainability was highlighted, and different tariff models applied in Latin American countries were analyzed.
One of the key points was the implementation of consumption blocks and the categorization of users to establish rates that promote savings and allow those with fewer resources to be subsidized. The difference between rates in a single part, that is, a charge per consumption or monthly amount, and rates in multiple parts, which can be a fixed charge or charge per consumption, was discussed; as well as different methodologies for calculating average costs.
In addition, the relationship between energy efficiency and sustainability was addressed, mentioning specific cases of methane recovery in wastewater or sewage treatment plants. It was concluded that this approach not only allows for greater operational efficiency, but also contributes to energy self-sufficiency and cost reduction.
The session concluded with a call for the implementation of more efficient tariff structures, which not only reflect the real costs of the service, but also encourage savings and allow greater equity in access to drinking water. Likewise, the importance of including long-term sustainability criteria was highlighted, both in the investment and in the operation of water services.
