Water Wastewater Component

class aaem.components.wastewater.component.WaterWastewaterSystems(community_data, forecast, diag=None, prerequisites={})

Bases: aaem.components.annual_savings.annual_savings.AnnualSavings

Wind power component of the Alaska Affordable Energy Model: This module estimates potential improvements in heating and electrical efficiency to water and wastewater systems. Consumption and savings are calculated based on system type, population, and heating degree days per year for a community. Project costs are based on audits, or estimated by the community size.

Parameters:

community_data : CommunityData

CommunityData Object for a community

forecast : Forecast

forecast for a community

diagnostics : diagnostics, optional

diagnostics for tracking error/warning messages

prerequisites : dictionary of components, optional

prerequisite component data this component has no prerequisites leave empty
