Worked example: SSP in Newtown

Overview

This worked example gives a hypothetical case of sanitation safety planning (SSP) in a small municipality called Newtown in an imaginary country called the Republic of Sanitola. The Republic of Sanitola is located in the tropical climate zone and is a middle-income country. Newtown is a town on the outskirts of a large metropolitan city and has a population of approximately 50 000 people. The population in Newtown has increased considerably during the past 10 years, and the rapid population growth has posed challenges for the town’s infrastructure. Water supply is from a surface water source located far upstream of the town. Seasonally heavy rains occur in the area. However, the beginning of the wet season is becoming less predictable. Further, regional climate models predict that average rainfall will decrease during the dry season and increase during the wet season over the next 30 years.
