*[[Practitioner's Tool / Technology and Operation / Sewage_Lagoons|Sewage Lagoons]]: Sewage lagoons are lined ponds or basins that treat wastewater through&nbsp;the physical action of settling and the biological action of microbial digestion. Also known as waste stabilization ponds, sewage lagoons are popular because they are relatively inexpensive and easy to design, install and maintain and can produce a good quality effluent. They do, however, require large land areas. See also:<br />
