Tier A - Initial assessment — Estimation of GHG emissions

Assessment period: days
Emission factor: kg CO2eq/kWh
Annual protein consumption: kg/person/year
BOD5 generation (wastewater): kg/person/day
Water supply
0 / 0
Wastewater
0 / 0 / 0
Faecal Sludge Management
0 / 0
The reset button does several things:
  1. Sets the tier B values to 0, except the tier A ones.
  2. Sets "Are you producing biogas?" to "No".
  3. Sets "Are you valorizing biogas?" to "No".
  4. Sets "Select main treatment tye" to "None".
  5. Sets "Select sludge disposal method" to "None".
  6. Sets the 4 options for Faecal Sludge Management to default (Containment type, treatment type, disposal type and type of faecal sludge).
All the inputs that have estimations are set to zero:
  • Wastewater estimations set to 0:
    • Biogas produced = 0
    • Percentage of methane in biogas = 0
    • Biogas valorised = 0
    • Biogas flared = 0
    • Influent BOD load = 0
    • Effluent BOD load = 0
    • BOD removed as sludge = 0
    • CH4 emission factor = 0
    • Sludge produced in WWTPs = 0
    • Dry weight in sludge produced = 0
    • Sludge composted = 0
    • Sludge incinerated = 0
    • Sludge sent to land application = 0
    • Sludge sent to landfilling = 0
    • Sludge stockpiled = 0
    • Fluidized Bed Reactor Temperature = 0
  • Faecal sludge management estimations set to 0:
    • Influent BOD load = 0
    • CH4 emission factor = 0
    • Faecal sludge density = 0
    • Volume of faecal sludge emptied = 0
    • BOD concentration of faecal sludge = 0
    • BOD removed as faecal sludge = 0
    • Effluent BOD load = 0
    • BOD removed with excess sludge = 0
    • Biogas produced = 0
    • Biogas valorized = 0
    • Biogas flared = 0
    • Methane in Biogas = 0
    • Dry weight sent to landfill = 0
    • Dry weight sent to land application = 0
    • Volume of faecal sludge dumped = 0
Then, the estimations will be recalculated again refilling the input fields and the options.
Note that this button does not affect the possible substages that the user may have created previously.
