A Sanitation (or Shit) Flow Diagram presents a clear picture of how excreta flows are managed within the city. The diagram clearly depicts how excreta flows from user interface to the final disposal. It has the following stages:
➣ The city has 100% coverage of sewer network which has been completed recently but it is not functional yet, as the Sewage Treatment Plant (STP) is still in construction phase, scheduled to be completed only by 2018.
➣ Types of containment systems observed in the city during the field-based study illustrated in the SFD diagram:
• A fully lined tank (sealed) connected to open drain is attributed to be from 46% of the population.
• Septic tanks connected to open drains is attributed to be from 44% of the population with 74% of the households having double chambered septic tanks while 26% having three chambered septic tanks.
• Toilets discharges directly to open drains without any containment system is attributed to be from 6% of the population.
