RAIN WATER HARVESTING CONTROL SYSTEMMASTER OF ENGG. in ELECTRONICS DEVAL DIXIT
WHAT IS RAIN WATERHARVESTING Rainwater Harvesting is a technology utilized for collecting and storing rainwater from rooftops, land surfaces or road surfaces using simple techniques such as barrels, tanks and cistern method. Harvested rainwater is a renewable source of clean water that is ideal for domestic and agricultural uses as a supplementary source. Rain Run off water from Water storage in Water utility action(s) catchment reservoir
IRELANDS CLIMATE Irelands climate is influenced by the Atlantic Ocean. On average it rains 190 days of the year. Rainwater harvesting is ideal for Ireland’s high level of rainfall.
SCOPE OF STUDYAims and Objectives To develop a small scale project that provides the outstanding practice for energy efficiency measures and rain water harvesting. To measure the water savings from the rain water harvesting. Develop the control system that assess the quality and monitoring the volume of harvested water. Optimizing the model for a detailed financial analysis (low cost) with emphasis on domestic installation.
ECONOMIC ANALYSIS OFRAINWATER HARVESTING Estimated cost benefit for rainwater harvesting facility with 2mᶾstorage tank. In the domestic scenario, rainwater harvesting has a vital role to play in reducing mains demand. Rainwater can, depending upon demand for toilet use, substitute between 37-100% of mains water for toilet flushing facilities. This in turn leads to an overall saving of between 19-33% curtailment in demand for mains water. Cost of treatment of water taken at €0.34/m3.
TECHNOLOGY REVIEW Capacitive Sensor : Here capacitive sensor is employed as a Insufficient rainwater control monitor. It will sense the water level of the rainwater header tank The Texas Instruments MSP430 family of ultra- low-power microcontroller is in use, it consists of several devices featuring different sets of peripherals addressed for various applications.
The MSP-EXP430G2 Launchpad is an easy-to-use flashprogrammer and debugging tool for the MSP430G2xx ValueLine microcontrollers. MSP-EXP430G2 Launchpad for MSP430 16-Bit Microcontrollers
CONCLUSIONS Rainwater harvesting is a viable water conservation measure that has the potential to accord to the sustainability of raw water sources and to the viability of water treatment plants. Harvested rainwater has potential to provide augmented source to treated mains water for non-potable uses. There is need to be ample aid in the forms of grants or other schemes from the government to promote the installation of rainwater harvesting systems in Ireland. The potential benefits of rainwater harvesting are not widely apprehended and this should be addressed through educational awareness programmes.
BENEFITS OF RWH SYSTEM Notably reduces water charges and water utility expenditures. Following installation of rainwater harvesting system it is completely free to use and requires little or no maintenance. Rainwater systems can easily be installed into premises normally within 48 hours at site. Rainwater is an inevitable and pure form of water. Curtail demand on municipal water supply.
