Entering and editing information about zones balances (inflows, outflows and storage sensors) and zones characteristics.
Zones should correspond to isolated areas of the system, surrounded by closed valves and where all inflows and outflows (if exist) must be measured. Zones can include for example DMA (District Metered Areas), pressure zones or operational zones. The configuration of the inflow and outflow sensors as well as tanks levels are done by editing the Flow In, Flow Our and Storage Columns. As an important note, the tank levels that should be considered for the zones balance are only those that are inside the zones boundary and serve as storage for the zone - this means that if a zone is supplied by a tank and the inflow sensor is located immediately downstream the tank, this tank level must not be considered.
Zones information can only be inserted/edited after zones are created in WaterSight, and this only happens after a zones shapefile is imported in WaterSight, in the GIS configuration page. After zones are created the user can manually insert/edit information related to each zone:
Note: System Total zone is always automatically created (this information does not come from GIS shapefile) and represents the all system.
To add more zones, the user needs to upload a new zone shapefile, in the GIS configuration page.
