Management of River Basin Physical Assets
River basin management involves, among other activities, the operation, maintenance and renewal of existing water and wastewater physical infrastructure assets, as well as the planning, designing, procurement and construction of new water infrastructure assets, in order to provide and secure present and future water demand, and other services, such as flood control and mitigation. Focus is set on increasing demand issues and uncertainty in available resources due to climate change. But there is a challenge also in the management of an aging portfolio of critical infrastructures, including storage, diversion and flood protection facilities, water wells, water conveyance facilities and wastewater treatment plants. Though physical asset management methodologies are well developed and established, such as ISO 55001, their application to infrastructures managed by river basin authorities is not widespread. This chapter presents key components for effective management covering the following aspects: asset monetary valuation; asset condition assessment; estimation of risks linked with asset condition; planning and prioritization of capital and maintenance expenditures; and expected impacts on water tariffs. A raw water distribution system in the Segura River Basin in Spain has been used as case study.
