Gayflower 2.0 Cost Estimates
This is an overview of the costs and benefits of using a single trailer for shower, toilets, fresh, and grey water as opposed to using OSS services (what's OSS, you ask?).
Assumption: 2300 gallons fresh water, 2300 gallons waste water (mostly grey), two toilets, 2025 OSS pricing.
Scenarios:
OSS + Portos - using OSS providers with portopotty rental
OSS + Ecozoic - using OSS with Ecozoic toilets
Gayflower - using the Gayflower
Water Only - using a water trailer for fresh and grey water; OSS for everything else
