The article offers tasks on functional literacy on the topic "The Mariinsky water system". It was not by chance that we chose this topic, since our Ascension (the place where we live) was formed in the middle of the XIX century on the site of the Voznesensky churchyard and the village of Svirskoye Estuary in connection with the construction of the Mariinsky water system. The tasks are intended primarily for students of the sixth and seventh grades. The answers to the tasks are presented at the end of the article.
