In the early 1970's, the primary concern of the wastewater construction industry was watertightness. At that time, as it is now, precast concrete was recognized as the construction material best able to provide strength and durability in underground structures. The key however, to protecting public health and safety as well as the local environment was a watertight connection between pipeline and structure. In order to address this need, the original A-LOK connector design was conceived.
