Tangki NAHRIM
Overview
Overview
Tangki NAHRIM is developed for the calculation of optimal tank size for rainwater harvesting in Malaysia.
The latest upgraded version, Tangki NAHRIM 2.0 is available as a web application: [Tangki NAHRIM 2.0]
This web app calculates the efficiency (water savings) of rainwater harvesting system by tank sizes. Based on your inputs such as rainfall, roof area, and your daily water demand, the web app will calculate the water-saving and storage efficiency for the range of tank sizes that you choose to be compared. You can adjust your inputs for the rainwater harvesting system and finally select a tank size which fulfils your required level of performance (in this case, water savings).
The built-in rainfall data covers all Malaysia, which will benefit all Malaysians, as well as people from all over the world since custom rainfall data can be used in this application.
