The document discusses Cape Town's water supply and demand over time. It notes periods when water restrictions were imposed dating back to 1872, often due to low rainfall and the need for new infrastructure. Charts show dam storage levels and monthly water consumption from 2004-2005. The document also outlines Cape Town's water supply sources, wastewater infrastructure, service levels, informal settlement sanitation backlog, and factors affecting service delivery.

24. Factors affecting effective service delivery Settlements that are very dense No formal services close by Vandalism & blockages from community No formal tracks to allow access for the cleaning and maintenance of services. Lack of education and awareness around proper use of water and sanitation and linked effect of health and hygiene
