Rainwater as a Alternative Source of Water Supply in Building – Measurements and Evaluation

Abstract

There are many water sources available on building sites that can be use as a alternative water sources for supplement the more traditional water sources. These water sources are usually suitable for non-potable purposes and vary greatly in quality so that the most of the on-site water resources have limited application and of course are never suitable for human consumption. Rainwater harvesting appears to be one of the most promising alternatives for supplying freshwater in the face of increasing water scarcity and escalating demand. Advantage of the rainwater harvesting is availability in the most places over the world and that rainwater usually is one of the purest waters available of all the alternate water sources. Submitted paper contains an overview of the possible rain water use for non-potable purposes in one school buildings as well as a possibility of the rainwater harvesting for buildings in TUKE campus as a planned concept for rainwater management.

Rainwater harvesting and greywater recycling as alternative water resources: a survey of public opinion

“…Taking into consideration the fact that cities consume almost 70% of the world's resources, including water resources, a modern economy that is based on sustainable consumption and the use of alternative sources of water such as rainwater and greywater [9][10][11][12] is needed. In recent years there has been an increase in the ecological awareness of the public, which has resulted in more and more buildings with a reduced demand for water and energy [13][14][15][16][17].…”

Hydrodynamic modeling of the impact of residential rainwater harvesting systems on stormwater runoff and drainage networks

“…The method of using rainwater is influenced by their quality and quantity as well as the methods of their purification [22]. However, in the vast majority of cases rainwater is a source of water for toilet flushing [23][24][25][26], cleaning, washing [27], car washing [28], irrigation of green areas and crop irrigation [29][30]. The popularity of RWH systems is increasing all over the world.…”

Evaluating the financial efficiency of energy and water saving installations in passive house

“…This is an accomplishable step through the use of alternative sources of water such as the use of rainwater and graywater sources [15][16][17]. Such models for managing water resources of varied quality parameters is compatible with contemporary requirements for water and sewage economy that is being implemented in accordance with the principles of sustainable development.…”
