Implementation Organization : Khorasan Razavi Agricultural and Natural Resources Research Center
(KANRRC) and Seoul National University Rainwater Research Center (SNURRC)
Country : Iran
Project Area : Climate change and fresh water
NetRes : IGES
Duration of Project : 24 months
Status : Ongoing
Summary
The City of Mashhad, located in the northern part of Iran and with annual average precipitation of 250 mm, is currently suffering from water shortage due to climate change and population growth. As one of the water resource conservation and climate change adaptation policies, a RWH demonstration project with 100 m3 rainwater storage tank and necessary system will be installed at the office building of Khorasan Agriculture and Natural Resource Research Center (KANRRC). A rainwater information center which showcases rainwater practice and technology will be provided for public education.
The quantity and quality aspect of the RWH system as well as public acceptance will be monitored during two year project. One national conference for the public officials and general pubic will be held each year. The progress and result of this project will be introduced nationally and internationally through IWA (International Water Association) publications.
The scientific and engineering data from this demonstration project will be used as the basis of new water regulation in the city of Mashhad and Iranian government as well. The project site will provide a good education place for the citizens and millions of visitors of this holy city.
Key Activities
a) Design of RWH system and desk studies
The design of the system is the most vital part of the project to demonstrate the multipurpose use of RWH. For design of RWH system, several information should be gathered including the hydrology, collection from the roof catchment, conveyance, storage and water usage. The most important thing is to study the traditional RWHM practice in this region, because it must have been proven technically and it will attract peoples’ acceptance who will actually implement in these area. The applicability of RWH at rural area will be examined from the experience of underground dam which was already constructed by KANRRC.
b) Building the RWH system
The two story building where the RWH will be installed has 1700 m2 roof area, and the number of residents are 30 persons during daytime and 10 persons during night time. According to the preliminary design (as attached), the rainwater from the roof will be collected and filtered, then conveyed to the steel rainwater tank (100 m3 total). The water will be connected to the toilet and garden by pump. Devise to avoid cross-connection should be provided. According to the result of water quality measurements, recommendation will be made for possible drinking.
c) Monitoring
For the promotion of RWH system, the monitoring and analysis of operating data in terms of engineering and scientific aspects are the most important. The water quantity in the RWH system will be monitored including the rainfall, amount of water storage, water consumption for different purposes. The water quality at RWH system will be monitored including the rainwater, collected rainwater and stored rainwater. Periodic monitoring items will be pH, turbidity, temperature and microbial indicators. Annual monitoring items will be heavy metals or other items that might be of interest. Monitoring during the construction stage and during the maintenance stage will be made as well.
d) Promotion and National Seminar
The purpose of proposed project is to show the importance of RWH for water resource development and climate change adaptation. In KANRRC, a rainwater information room will be provided to showcase the information regarding the rainwater history, pilot projects, publications, posters and even small RWH equipments. The display materials will be provided with the financial and administrational support from the city of Mashhad and other agencies. This place can be used as a good education place for citizen and students. Two national seminars will be held before and after the demo project. At the initial stage, SNURRC together with KANRRC will make a national seminar at two cities, Teheran and Mashhad on July 2008. After the successful demonstration and operation, another national seminar will be held together with IWA on 2009.
e) publication
The project will be well documented and reported through IWA journals. Several technical and scientific findings will be published too.
