__NOTOC__
The City Sanitation Plan was developed in 2009 by the Water and Sanitation Program – South Asia (WSP-SA) for city planners to build seven-year investment scenarios.
'''It includes four possible city-wide sanitation interventions''': <br>
1) Septic tanks with soakaways or pit latrines, <br>
2) Partly septic tanks with soakaways or pit latrines with an off-site (conventional sewerage) component, <br>
3) Small bore sewerage, and <br>
4) Conventional sewerage.
It considers [[Capital_Expenditure_(CapEx)|capital expenditures]] and [[Operational_and_Minor_Maintenance_Expenditure_(OpEx)|operational and minor maintenance expenditures]], arrangements for household contributions, calculations for recovery from user fees, but does not include [[Capital_Maintenance_Expenditure_(CapManEx)|capital maintenance expenditures]] (Fonseca et.al, 2011). It provides different forecasts for population growth, but it lacks clarity on the inflation rates and cost projections. It is currently being used in several Indian cities.
