Description
E03B covers systems and methods for sourcing, gathering, and transporting water for supply purposes. This includes water intake structures, collection facilities, storage reservoirs, pumping stations, and distribution networks that deliver water from natural sources or treatment plants to users. The classification encompasses both above-ground and underground infrastructure, such as wells, boreholes, aqueducts, pipelines, and associated control or measurement devices. Related sewerage and wastewater treatment systems are addressed separately in other E03 subclasses.
