Strategy, Action Plan and Change Management

• Identify water losses
• Measure unbilled water volumes.
• Break them down according to their causes.
• Deduct the corresponding financial loss.
• Design a real and apparent loss strategy

Skills acquired:

• Understanding of the phenomenon of water losses (real or apparent) and their dynamics
• Understanding of the impact of the various activities of the company on the level of water losses Establishing a diagnosis on water losses (and hydraulic balance)
• Define a strategy to reduce water losses
• Establish an action plan to reduce water losses
• Monitoring the implementation of an action plan
• Condition for the sustainability of the results of an action plan, change management

Diego TOBAR RUBIO is a Civil Engineer with a Master’s Degree in Engineering with emphasis on water management with 20 years of experience on water and sewerage systems. Most of the time he has been dedicated to developing and implementing computational tools and technics for the optimization of the processes related with the transport and distribution of water systems and collection of sewerage systems. He has a high adaptability, mainly work oriented on goals and client’s satisfaction maintaining always the upmost quality and ethical standards.
From the beginning of his career, he has assumed multiples positions with in companies in charge of the water and sewer services which has allowed me to detailly known their processes and interactions, also their possible evolution as a response of the implementation of concrete and monitorable actions.
