Modelling rainwater harvesting for commercial buildings
Commercial areas are generally fully paved and with more impervious land cover than residential areas. This paper demonstrates a wall-mounted rainwater harvesting system designed to deal with limited land space. An arrangement of three tanks in series was used on a commercial shop lot where flat roofs generate large amounts of runoff. The system is compact, and can be installed and fitted ...

River Island in Milton Keynes Incorporates rainwater recycling system
River Island opts for Rainwater Recycling The large new stand alone River Island shop in Milton Keynes will incorporate an Aquaco Rainwater Recycling System. The entire rainwater harvesting system will be gravity fed and thereby negate the need for pumps. This will give even further cost savings on top of the reduction in mains water usage. The recycling system consists of 2 x 5,000 litre ...

Contributions to the design of rainwater harvesting systems in buildings with green roofs in a Mediterranean climate
Green roofs (GRs) are becoming a trend in urban areas, favouring thermal performance of buildings, promoting removal of atmospheric pollutants, and acting as possible water collection spots. Rainwater harvesting systems in buildings can also contribute to the management of stormwater runoff reducing flood peaks. These technologies should be enhanced in Mediterranean countries where water ...

Modelling of a roof runoff harvesting system: the use of rainwater for toilet flushing
The water balance of a four-people family rainwater harvesting system was calculated in a case study. The experimental water saving efficiency (WSE) was calculated as 87%. A simple computer model was implemented to simulate the behaviour of the rainwater harvesting system. In general, the rainwater collector volumes predicted by the daily model had shown a good correlation with the experimental ...

Designing domestic rainwater harvesting systems under different climatic regimes in Italy
Nowadays domestic rainwater harvesting practices are recognized as effective tools to improve the sustainability of drainage systems within the urban environment, by contributing to limiting the demand for potable water and, at the same time, by mitigating the generation of storm water runoff at the source. The final objective of this paper is to define regression curves to size domestic ...

Rainwater harvesting as source control option to reduce roof runoff peaks to downstream drainage systems
The objective of the paper is to evaluate the potential of tank-based rainwater harvesting systems in free standing houses as the source control method to mitigate peak roof runoff due to rainfall in urban areas. To this aim, the water balance simulation of the rainwater tank was carried out using both high resolution rainfall series and toilet water demand data extracted from the database of ...

Modelling runoff on ceramic tile roofs using the kinematic wave equations
Generally, roofs are the best candidates for rainwater harvesting. In this context, the correct evaluation of the quantity and quality of runoff from roofs is essential to effectively design rainwater harvesting systems. This study aims to evaluate the performance of a kinematic wave based numerical model in simulating runoff on sloping roofs, by comparing the numerical results with the ones ...

Assessment of rainwater harvesting systems at a university in Taipei
Rainwater harvesting systems (RWHSs), a pilot-scale one (PSR) and a full-scale one (FSR), at a university campus in Taipei were assessed. Characteristics of harvested rainwater were analyzed, including pH, electrical conductivity (EC), turbidity, alkalinity, dissolved organic carbon (DOC), total coliform (TC), concentration of 14 metals (Al, Ca, K, Mg, Na, Cu, Fe, Mn, V, Zn, Cd, Cr, Pb and Ni) ...

Controlling weather extremes – turning rainfall to an advantage
Shropshire and the surrounding areas are well known to experience seasonal flooding, according to the Shropshire Star. Whilst wet ground conditions can be a burden, triggering increased costs, lower output and extra work, the advantages of rainfall certainly outweigh the opposite extreme of the weather spectrum. Shaun Jones, rural professional director of Halls, Shrewsbury, explained that ...

Multi-criteria decision making methods for rural water supply: a case study from Bangladesh
Multiple criteria decision making (MCDM) is a process of evaluating alternatives against relevant decision making criteria. Several methods are available to facilitate the evaluation steps. This paper deals with a rural water supply problem in the coastal areas of Bangladesh. Three different MCDM methods – weighted summation, analytical hierarchy process, and novel approach to imprecise ...

Economic feasibility of rainwater harvesting systems: a systematic literature review
Rainwater harvesting (RWH) systems are increasingly being used as an alternative source of water supply. However, their installation is not often financially feasible. The feasibility analysis of such investments is carried out by traditional techniques that have uncertainty limitations. Thus, the objective of this study is to describe how the studies concerning the economic feasibility of ...
