How much are you spending on pump-and-haul right now?
Adjust the sliders to match your operation. See your pump-and-haul savings eliminated — plus the fertilizer value you're currently pouring down the drain.
How many Locale or Vault units you operate. One Virro unit per porta-potty or vault replaced.
How often a vacuum truck services your fleet. Active event fleets average 2–4 trips/week.
Fully loaded — truck, labor, dumping fees, disposal. PSAI national average: $75–$110/trip.
How this is calculated
The formula is straightforward. Here is what each variable represents and where the data comes from.
Number of active units. 1:1 replacement of existing porta-potties or vaults.
Event fleets average 2–4 trips/week. Construction sites lower. Festivals higher.
PSAI national average: $75–$110. Coastal metros and remote sites run 20–40% above average.
Conservative estimate for a Locale unit at typical event deployment density. Adjustable.
Conservative floor. Composted biosolids (Class A) sell for $10–$180/yd³ regionally. Municipal buyers often at the low end; landscapers and farms at the high end.
Human urine: ~9 g N/L. At $1/lb N retail, that is ~$0.0022/g × 9 g = $0.20/L nitrogen value. RO concentration increases this further.
Floor estimate — conservative by design. Excluded: scheduling labor, regulatory overhead, emergency service premiums. Assumes year-round operation; seasonal operators should scale by active months.
