I am looking for rain-water harvesting installation service for my 4-floor building. I have contacted the Modern Sanitaryware Vijayanagar, Bangalore for the work. They have arranged the 3 people for the installation work. They have taken 4 hours to complete the installation work. I have paid total RS 13000 for filter RS 8000 and installation work RS 5000. I am very happy with the service and work responsibilities of the agency.
