Water safety and quality are priorities in Swiss cities, including Pully, which is why the city performs
well across these indicators. However, Pully's consumption figures are significantly higher than the
average national levels of 160 to 170 litres per capita. Some of the difference could amount to per
11 12
capita consumption variance between urban and rural areas, as well as between water companies
with and without water meters.

Optimizing water consumption: It is recommended that Pully analyses this high variance and continues
to monitor how much customer water demands (employment and residential) account for the city’s
total water production volume. Pully should evaluate peak day and time water consumption trends,
in addition to the overall demand and production trends – taking into account seasonal temperature
and precicipation trends. The city should then set average water production projections and targets
based on its interval of choice according to customer demand and non-revenue water.

ITU Supplements such as ITU-T L Suppl. 14: ITU-T L.1500: ‘Standardization gap analysis for smart water
management’ and ITU-T L Suppl. 15: ITU-T L.1500 series: ‘Requirements for water sensing and early
warning systems’ should be utilized by cities when actualizing their smart water management policies.
