Closed drain system and and Open drain system
There are both closed and open drains in different areas. Closed drain form a complex network underground. The primary refuse from individual areas are collected and transported to a main network which finally goes to a treatment plant. Open drain are mostly used to collect wastewater that is not sewage. Use of open drains to dispose sanitary waste is extremely unhygienic and unsafe. Use of open drains to certain degree can be acceptable. However, any place with collection of water breeds various disease-carrying pathogens.
Use of open drains is not a good option to carry wastewater even if the solids have been removed by use of septic or interceptor tanks because people can easily come into contact with it. Moreover, since they are open any excess water can result in flooding. The only advantages of using open drains is in its convenience of construction and maintenance as it is easily accessible. This is why you can still see the use of open drains in rural areas. However, in densely populated urban areas, such a system will fail in its effectiveness
