The Impact

This paper explores the impact of water conservation and rainwater harvesting practices implemented at the site or district scale on the infrastructure, energy and water cycles of their larger urban systems. A case study is presented of a conceptual development in a Southeast Asian climate. Two technologies are examined: water-efficient fixtures and appliances and rainwater harvesting and beneficial use. Practices to reduce water consumption at the site or district scale have implications in the larger system, ranging from reductions in water that has to be treated and distributed, reductions in wastewater that has to be collected and treated, and reductions in energy consumed. Similarly, using rainwater for irrigation will reduce the amount of potable water demand, and will have system energy implications. The paper considers performance criteria for the entire water-energy system, including peak runoff, pollutant loads, energy and carbon footprints.

The Impact

The Life Cycle Cost (LCC) analysis on selected alternative systems was carried out to reduce the demand for potable water and energy in a detached house designed in accordance with the concept of environmentally friendly house. The tests included a rainwater harvesting system, graywater recycling system, solar panels, photovoltaic panels, air heat pumps, ground heat pumps, wind turbines, drain water heat recovery units, and biomass boilers. The analysis was made for many investment variants where different combinations of the mentioned solutions were applied. In addition to the LCC analysis, some tests were also carried out to determine an impact of the investment options on the environment. This was done by calculating CO2, SO2, NOx, CO and dust emissions. The research was carried out for a different number of occupants and variable levels of water consumption, which allowed determining the impact of these parameters on the results obtained. They showed that for any of the computational cases the traditional option of the installation was not the most advantageous solution in financial and environmental terms, and the systems in question could be an alternative to this option. Thanks to their implementation, the consumption of fossil energy resources and natural water resources will be reduced, and the emission of pollutants will be limited, which will contribute to an improvement of the natural environment.

ResumenLos humedales costeros de los municipios de Chimbote y Nuevo Chimbote, actualmente se encuentran en diferentes grados de depredación, contaminación y degradación ambiental. Producto de la consolidación del sector industrial y el “boom” pesquero, originados a mediados del siglo XX. Consecuencia de ello, los procesos de expansión urbana han generado la pérdida de un 65% de la superficie total de los humedales costeros de la región. En este sentido, la investigación tiene como objetivo, determinar si la infraestructura verde, es capaz de contener los procesos de expansión urbana y evitar la degradación y desaparición de los humedales costeros, a fin de reducir los impactos tanto antrópicos como naturales. Desde este enfoque, se procede a realizar un análisis general del estado actual de los humedales costeros de ambos municipios. Como resultado, se ha comprobado que integrándose la infraestructura verde en conjunto con otros espacios verdes o naturales y mediante una adecuada planificación urbana, se pueden contener los desmesurados procesos de expansión urbana, reduciéndose los impactos y consecuencias generados tanto por los procesos antrópicos y naturales.AbstractThe coastal wetlands owned by the municipalities of Chimbote and New Chimbote currently find themselves at different degrees of environmental depredation, pollution and, degradation. It comes as a result of the consolidation of the industrial sector and the fishing “boom,” originated during the middle of the 20th century. As a consequence, the urban expansionary processes have caused the loss of 65% of the surface of the coastal wetlands in the region. In this sense, this investigation’s objective is to determine whether the green infrastructure is capable of containing the urban expansionary processes and of avoiding the degradation and disappearance of the coastal wetlands, so it reduces the impact of both anthropic and naturals sources. From this perspective, it proceeds to perform a general analysis of the coastal wetlands’ current state, for both municipalities. As a result, it has been proven that integrating the green infrastructure along with other green areas, natural or otherwise, and through adequate urban planning, the excessive urban expansionary processes can be contained, reducing the impact and consequences generated by both anthropic and natural processes.

Positive Results

This paper describes the feasibility and probable benefits associated with greening the Tahliah Channel, a concrete drainage channel that was originally built to relieve urban flooding in Jeddah City, Saudi Arabia. It includes an estimation of irrigation needs for channel greening based on a standardized planting specification. The study also demonstrates alternative strategies for meeting the required irrigation demand, including water harvesting and graywater reuse on a residential scale. The study shows that greening Tahliah Channel is possible relying mainly on graywater reuse from the surrounding buildings. Also, the study shows that rainwater harvesting is not a reliable source for irrigation. Rather, it can cover only part of the irrigation needs (6%) and so can be used as a secondary supporting source. The positive results of this case study will be of interest to those in arid countries who are looking to upgrade and replace traditional, single function drainage infrastructure with more sustainable, green infrastructure systems. More specifically, the objectives of the study are consistent with the goals of the Saudi government’s ongoing initiative that advocates for more resilient and sustainable cities.

The Impact

The objective of this work is to assess the impact of rainwater use in single-family houses on drinking water consumption and on the urban drainage system by means of a case study of a condominium of houses in the city of Curitiba, southern Brazil. A quantitative evaluation of the rainwater volume used and spilled in the recovery system was carried out using two methods for sizing the rainwater tank capacity. Using daily rainfall data and three demand scenarios of water consumption, it was possible to verify the efficiency and reliability of the adopted systems. Furthermore, in order to verify the impact on drainage, the greatest rainfall in the series was assessed and then it was possible to measure it by comparing the hydrograph peak flows with and without the rainwater harvesting systems in the watershed outfall, corresponding to the storage tanks (concrete boxes) in the condominium. It was concluded that there was a decrease in the peak flow of 4.9% and 4.4%, respectively, in the two storage tanks evaluated when the rainwater tank capacities were estimated using the method based on the German Practical Method.
