Consumption Sector

One Consumption Sector is an element that concentrates the data demand populations: per capita consumption, return coefficient, population, etc. The consumer sector contains the following properties:

• Identification
  • Description - Use a friendly description when the item name is not enough
  • Parent List - Node to which this item belongs
  • Name - Item Name
    Avoid names that are too long, or that contain the following characters: '*', '>', '<', '/', '\', '"', ':', ';', '|', '=', '`', '#', ',', '?'
  • Priority - Information about the current state of the item. It might be: Neutral: no problem Warning: some problem, but that does not prevent the use or calculation Critical: Some issue that prevents the item from being calculated or used
  • Object Type - Object Type
• Object
  • Style - Style applied to the object
  • Layer - Current layer of the object
• Percapta
  • Percapta Consumption - (q) Perceptible consumption
  • k1 - Coefficient k1
  • k2 - Coefficient k2
• Population Projection
  • Calculation Method - Population projection calculation method
• Water
  • Demand in March - Demand calculated for the entire network based on the population served DemandOn March = Qproject / LFicP
  • Pressurized Pipes - Total fictional length of pressurized pipes associated with this sector (LFicP)
  • Project Flow - Calculated flow for the population to be served Qproj = k1 * k2 * GetEndPop * q
• Sewer
  • Coefficient of return - (Ctr)
  • Cont. in Final Gear - Contribution in Final Gear (QMF) QMF = k1 * k2 * Ctr * Pfim * q
  • Cont. in Initial Gear - Contribution in initial gear (QMI) QMI = k2 * Ctr * Pini * q
  • Contr. Final - Contribution rate in final gear (Tf) Tf = QMF / LtotalFic
  • Contr. Initial - Contribution rate in initial gear (Ti) Ti = QMI / LtotalFic
  • Infiltration rate - (TInf) Water infiltration rate in the pipe
  • Minimum Trative Tension - (Tmin) Minimum tensile stress to be checked in the pipeline
  • Sewage Pipes - Total fictitious extension of sewage pipes associated with this sector (LFicS)

Note, by default when creating a network these values are read from the Sector Patterns

For the dimensioning of a water or sewage network, after launching the network from model space, it is necessary to evaluate the population that will be served at two different times:

• Start of the Project - at the start of the plan, or at the beginning of the operation, the development is not yet fully occupied. Thus, it is necessary to evaluate the minimum tensile stress inside the pipes, so that the sludge flow does not settle, clogging the network
  • Initial Population - (Pini) - It is the total population that will be served from the moment the network starts operating.
    Note that it is the population served only by the network in question. If more than one sewer network exists, this population must be only the one served by this network.
  • Cont. In Initial Gear - (QMI) - Contribution in starting gear QMI = k2 * Ctr * Pini * q
  • Contr. initial - (Ti) - Contribution rate in initial gear Ti = QMI / LtotalFic
• End of Project - At the end of the plan, or at the end of the period of population growth, there may be a saturation of the network, so it is necessary to check the Maximum flow depth
  • Final Population - Population at the end of the project
    (Pfim) - It is the total population served at the end of the occupation period of the area where the network will be implemented. Note that it is the population served only by the network in question. If more than one sewer network exists, this population must be only the one served by this network
    To calculate the population at the end of the project, choose one of the population projection methods
  • Cont. In Final Gear - (QMF) - Contribution in Final GearQMF = k1 * k2 * Ctr * PFim * q
  • Contr. Final - (Tf) - Contribution rate in final gear Tf = QMF / LtotalFic

To calculate the contribution and demand rates, the Consumer Sectors need to be associated with the pipes of the networks.

This association can be made:

• during the network launch, setting in the network properties, the standard consumer sector,
• or after launch, select all pipes in the network that generate demand or contribution and edit the property Consumer Sectors

The commands for editing sectors are:

• SSECTOR - to create Consumer Sectors
• SPROPS - to edit the consumer sector properties
• SSECTORSTYLES - to edit Sector Styles
• SEDITSTYLE - to edit the consumer sector style
• SDISCONNECT - to disconnect devices or sectors
• SCONNECT - to connect devices or sectors
• SADDVERTEX - to add vertex to consumer sector
• SDELVERTEX - to remove vertex from consumption sector
• SADDLABELS - to add label to the consumer sector
