Rapid urbanization and population growth necessitate increased, and increasingly effective, investment in urban sanitation services. Ideally, new investment decisions would be informed by relevant cost data from existing systems. Unfortunately, the empirical data on the real costs of urban sanitation are sparse, and the little available data cannot be meaningfully analyzed due to wide variation in technologies, inconsistencies in classification of costs, and the rarity of actual systems encompassing the full sanitation value chain. Even the most sophisticated modeling tool requires high-quality data to generate actionable insights, and to date, such high-quality data on the real costs of urban sanitation are unavailable.

Climate and Costs in Urban Sanitation (CACTUS) offers a standard framework for collecting, analyzing, and reporting the highly complex and variable costing data that exists for current sanitation systems based on clear cost categories and distinct clusters of sanitation technologies that facilitate comparisons. Drawing on a robust foundation of empirical data collected to date, CACTUS generates standard cost reporting metrics - total annualized cost per household (TACH) and total annualized cost per capita (TACC), which incorporate total capital and operating costs over the full lifetime of the sanitation system.
