Pump-Out Pricing Calculator
Pricing tool for a Central Texas luxury restroom-trailer rental company: per-gallon pump-out price plus a live Google Maps-routed fuel and drive-time surcharge.
Replaces flat mileage guesses with the real route from where the truck is parked, so every quote covers fuel and drive time.
A single-page calculator that prices a pump-out by gallons and adds a distance surcharge from the real, traffic-aware Google Maps route between the company's truck yard and the job. When live routing is unavailable it falls back to ZIP-centroid distances, and then to manual miles.
Drive times are calibrated against about 25 reference routes across the 18-city service area, with metro-level handling for Austin and San Antonio. Built and shipped on 2026-09-03.
