The water and sewerage companies completed 1 to 7 of the following tables, while the water only companies completed tables 1, 2 and 7 on their cost and activity information.:
- Water service by expenditure
- Explanatory variables and volume measures for the water service
- wastewater service expenditure by purpose
- Explanatory variables and volume measures for the wastewater service
