Enhanced Performance and Design of Rainwater Harvesting Based on Rainfall Regime – The Case of Ethiopia

his paper deals with an effective and enhanced performance of rainwater harvesting systems using rainfall regimes, so that economical and efficient sizing of storage is met. These days, there are a number of ways of rainwater harvesting techniques. One of the most effective option and technique is harvesting from roof catchments for household and communal /public domestic water services. Roof catchments gives very good runoff coefficient value and produce better amount and qualityof water. Losses in the form of infiltration, interception or subsurface run off etc are in existent.

Experimental study on pollutants removalfrom first flush by filtration through four filter medias

It will be one effect way to collect and use rainwater for solving problem of shortage of water resource in big city. The utilization of rainwater by scientific and economical technology can obtain the benefit of water saving, groundwater conservation, reduction of flood accident, decrease of volume of water treatment plant, and ameliorate climate and improve entironment. The effect will be remarkable using rainwater in developing city and for its sustainable development.

Financing Mechanisms for Roofwater Harvesting An example from Uganda

Roofwater harvesting in Africa has too long been implemented only within an aid projects setting. Work and further development has been concentrated on the hardware aspects (like optimised construction of the tank, simple guttering systems, foul-flush devices, filters, etc.). The software part such as influencing the national water policy to integrate roofwater harvesting, developing suitable strategiesfor mainstreaming or advocacy on different levels has long been neglected.

Identifying Social Attitudes and Barriers to Water Conservation – A Community Water Survey

In 2003, Eurobodalla Shire Council adopted its Integrated Water Cycle Management Strategy (IWCMS), which suggested that appropriate levels of Demand Management could be achieved through targeted customer rebate and community education programs. Whilst various education and incentive programs targeting water conservation had been previously run, it was felt they lacked a “documented” strategic approach, adequate monitoring and evaluation and any detailed knowledge of local people’s attitudes to and the level of uptake in the Community of various water saving devices.

Innovative Rainwater Harvesting and Management in the Republic of Korea

Coupled with the recent recognition of the importance of rainwater harvesting and management (RWHM) to solve many of the world’s water problems, the promotion of RWHM is growing rapidly throughout the world. RWHM is believed to have a major role as a type of sustainable infrastructure by enabling developing countries to meet the Millennium Development Goals and as a sustainable technology for developed countries. Despite the severest climate conditions in Korea, the people have survived for thousands of years accumulating knowledge and wisdom in rainwater management, although it is sometimes forgotten or thought to be outdated.

Insights From The Design, Construction And Operation Of An Experimental Stormwater Biofiltration System

Biofiltration systems are being installed on an ever-increasing scale, both for stormwater quality improvement and as a component of stormwater reuse systems. However, there is currently a general lack of knowledge regarding their design, implementation and performance. This paper reports on the issues encountered and lessons learnt during the installation and operation of an experimental biofiltration system. While the water industry familiarizes itself with biofiltration technologies, effective communication and clear guidance is required to ensure successfulconstruction and operation of biofilters.

Institutional, Policy Development and Capacity Building for Promotion of Rain Water Harvesting in Sri Lanka

At Present, Sri Lanka has high rainfall volume being about 5900cu.m/ capita per year. By its geographical position and the location of its central hills, it is blessed with two monsoons namely; the South West (May- September) and North East (December- February), interspersed by two inter-monsoons. Island-wide receive some amount of rain annually even though varying in intensity, but never fails entirely.

Intelligent Sizing of Detention Basins Using a Dynamic Hydraulic Model

Stormwater detention basins are an important part of Water Sensitive Urban Design (WSUD). When designing such a structure it is critical to size the basin correctly, but the problem of determining the correct size for a detention basin is far from trivial. Fortunately, purpose-built hydraulic modelling computer programs can perform much of the computational ‘heavy lifting’ – allowing engineers to make a better estimate of required detention basin size. This paper investigates the use of one such hydraulic model (CivilStorm by Bentley) in the design of a detention basin (and associated appurtenances) in a hypothetical urban design scenario.

A Legionnaires’ Disease Outbreak, A Water Blaster And Roof-Collected Rainwater Systems

In February 2006, an outbreak Legionnaires’ Disease (LD) was identified in Beachlands, a small, isolated East Auckland suburb. It was investigated using case finding, a case-control study, sampling potential sources of infection, and by molecular typing (using sequence-based typing (SBT) of all Legionella pneumophila serogroup 1 (Lp1) isolates). Four cases were identified.

A Study on the Impact of Rainwater Tanks on Streamflow Runoff

Rainwater tank has become an Australian icon of water conservation. This paper examines the possible reduction in streamflow volume in a catchment due to installation of large number of rainwater tanks. The study uses rainfall and runoff events data from the Bremer River Catchment in southeast Queensland in Australia. This assumes hypothetical urban development on the catchment covering 20%, 40%, 60%, 80% and 100% of the catchment area and a 10kL rainwater tank is fitted in each household of the developed part of the catchment.
