The Arvind textile mill located near Kalol, Ahmedabad District, India uses over 6.5 million m3 of process water per year. Limitations on groundwater extraction coupled with the lack of a nearby location for effluent discharge led to the implementation of a complete water reuse system.

The total water available from the local aquifers is approximately 1.5 million m3/yr with the rest of the process water being provided through wastewater re-use. The unit cost of re-using process waste water was between $4-6 /m3 which is a very high unit cost particularly when compared to ground water abstraction rates.
