The developed Sewer Network ontology (SewerNet) describes the structure of the wastewater and stormwater networks, their elements, and their qualities. SewerNet is aligned with the DOLCE-lite foundational ontology and imports a few axioms from the Time ontology providing a well-established semantic basis for modeling sewer networks.
