Abstract
ABSTRACT Reliability analysis is usually required as input for feasibility assessments of rainwater harvesting (RWH) systems. This study introduces the concept of elasticity between the volumetric reliability and a cost function to optimize the storage capacity. The elasticity was estimated for three tanks at a campus of the Universidad de Santander, Colombia; by means of a daily water balance under specific conditions of demand (non-potable uses), infrastructure (area and coverage of surface), and climatic variability. This method showed that, the average expected efficiency ranges from 29% to 58% with tanks of 60 m3. These values are 7–10% lower than those expected just from the water balance, but the size of tanks decreases by up to 53%. Therefore, the present method allows not only a comparison between expected efficiencies from average estimations with the optimization from daily water balance, but also with that estimated in conjunction with costs.
期刊介绍:
Urban Water Journal provides a forum for the research and professional communities dealing with water systems in the urban environment, directly contributing to the furtherance of sustainable development. Particular emphasis is placed on the analysis of interrelationships and interactions between the individual water systems, urban water bodies and the wider environment. The Journal encourages the adoption of an integrated approach, and system''s thinking to solve the numerous problems associated with sustainable urban water management.
Urban Water Journal focuses on the water-related infrastructure in the city: namely potable water supply, treatment and distribution; wastewater collection, treatment and management, and environmental return; storm drainage and urban flood management. Specific topics of interest include:
network design, optimisation, management, operation and rehabilitation;
novel treatment processes for water and wastewater, resource recovery, treatment plant design and optimisation as well as treatment plants as part of the integrated urban water system;
demand management and water efficiency, water recycling and source control;
stormwater management, urban flood risk quantification and management;
monitoring, utilisation and management of urban water bodies including groundwater;
water-sensitive planning and design (including analysis of interactions of the urban water cycle with city planning and green infrastructure);
resilience of the urban water system, long term scenarios to manage uncertainty, system stress testing;
data needs, smart metering and sensors, advanced data analytics for knowledge discovery, quantification and management of uncertainty, smart technologies for urban water systems;
decision-support and informatic tools;...
