Water reuse can include reusing water from many sources. Sometimes it is used water from bathing or dishwashing, and other times it is managing agricultural runoff. It may also be keeping/extending the water you have in reservoirs or groundwater and taking measures to reduce evaporationall in support of reuse. Reusing waste water is also very popular worldwide, especially for irrigation. Other names include “water recycling,” “water purification,” “reclaimed water,” “recycled water,” “reuse water,” and “repurified water.”
Water reuse is a well-known concept and part of the [[3R (water) – Recharge, Retention and Reuse|3R process (recharge, retention, reuse)]]. In this way, managing water well is thought of as a "buffer" to insure consistent supplies - A buffer between the user and the bad effects of drought or an unreliable water resource.
===Benefits and disadvantages of reusing wastewater for agriculture===

There are both positive and negative implications of wastewater reuse. The positive implications include: employment generation, food security for urban and peri-urban poor farmers, reliable supply of irrigation water and the recycling of nutrients in wastewater. Since wastewater is available all year round, the urban poor farmers and migrant laborers are assured of employment throughout the year. In the peri-urban areas along Musi, Hyderabad, it was found that wastewater-irrigated paddy contributes almost 43% of household food consumption. The high nutrient content of the wastewater helps farmers save on the fertilizer costs and its reliable supply helps increase the cropping intensity. Wastewater can also have a positive or negative impact on the property values. In Haroonabad, in Pakistan, the wastewater-irrigated land has a higher value than the canal-irrigated land.
