So this is something we actually support more-or-less already, but it is not documented in the OWRS repo and we didn't emphasize it during data collection. I think we may have commented out the sections of the survey that collect WW rate info before sending out it out last year.
The basic approach just adds additional sections that append _wastewater
like below:
FIRE_SERVICE:
service_charge:
depends_on:
- meter_size
values:
1": 7.63
2": 7.63
3": 22.15
4": 47.19
6": 137.08
8": 292.11
10": 525.31
12": 848.52
commodity_charge: flat_rate_commodity*usage_ccf
flat_rate_commodity: 0
fixed_drought_surcharge: 0
variable_drought_surcharge: 0
fixed_wastewater_charge: 0
variable_wastewater_charge: 0
bill: service_charge+commodity_charge
Then the bill calculation would need to become
bill: service_charge+commodity_charge+fixed_wastewater_charge+variable_wastewater_charge
In terms of todos, mainly seems like
rateparser
supports most common types of WW rates.Ah great! For exhaustiveness, are there budget based wastewater rates? How would that be specified?
I believe yes, but would need to dig into the source of the rateparser
and refresh my memory.
Count that in the "update documentation" bullet.
One noted enhancement of OWRS would be to add in wastewater rates. Chris what are your thoughts on how to incorporate?
Thinking this would be a separate section of each OWRS file that follows the same fixed / volumetric breakdown.
In terms of existing data sources, the Water Boards collects and issue the annual Wastewater User Charge Survey Report
https://www.waterboards.ca.gov/water_issues/programs/grants_loans/srf/docs/fy1617/fy1617ww_user_charge_survey.pdf
And here you may find those reports since 1996-97

Also worth looking at EPAs clean watersheds Needs Survey that assess the capital investment needed for publicly-owned wastewater collection and treatment facilities to meet the water quality goals of the Clean Water Act.
