Folder Non-Revenue Water

Non-revenue water (NRW) includes physical losses (pipe leaks) and commercial losses (illegal connections, unmetered public use, meter error, unbilled metered water, and water for which payment is not collected).

NRW levels are high in many developing countries, and they can be expensive to reduce.
