Non-Revenue Water or NRW is the amount of treated water that is put into a supply system but does not bring in revenue to the water supply company. The main components that contribute to NRW are pipe leakages, reservoir overflows, meter under-registration and illegal connections. Our engineers offer solutions to help eliminate the impacts of NRW to your revenue stream and operational expenses for a more sustainable result.
