Birthday of the LSP
Part one: The aqueduct

Preface : The Taitsky underground aqueduct is a wonderful architectural creation. It is 17 kilometers long and has been built in XVII century. In 80-s years if XX it was repaired by LSP members and functioned for several years. The aqueduct has a number of service wells. We decided to check the situation and to understand whether it is possible to repair it again.
