The introduction begins witha brief overview of wetlands: their nature and services offered. These wetlands are ecosystems with water that is static or flowing and characerized by emergent , floating and submerged aquatic vegetation. Some of the services provided by wetlands are fish and fiber, water supply, water purification, flood regulation, recreational opportunities and tourism. It then details the importance of wetlands for water purification.Toxins enter the wetlands through farms, factories and runoff. These toxins are broken down or otherwise buried using a variety of bacteria.

The historical lakes of Udaipur, Rajasthan, namely Pichola - Swaroop Saagar and Fatah Saagar are more than a century old. Filling them above original design full tank level on public demand or over enthusiasm may prove to be a threat to safety.

Desilting is becoming a major component of any Lake Conservation Project now a days. The basic reasons given for necessity of desilting are - increasing the storage capacity and checking eutrophic conditions.

As it is not practicable to reverse the slow process of silting in the bed of lakes through which only silt can be removed, there is no word like 'desilting' in any standard English dictionary. What we are doing in the name of 'desilting' is practically 'digging' or 'excavation' of lake bed. By so called desilting, the original lake bed is disturbed which has far reaching adverse effects on the performance of the lake. Most visible effect is the increase in percolation rate resulting in heavy seepage losses through the lake bed as observed after massive desilting at Pushkar lake in 2009.
