Campground Potable Water and Dump Station Guide for Campers and RVers

Potable water systems at public campgrounds

Access to drinking water varies widely across public campgrounds. Understanding how federal and state campgrounds configure water delivery prevents plumbing emergencies.

Potable water spigots supply municipal-grade or tested well water safe for drinking, cooking, and tank filling. These spigots are distributed throughout campground loops, typically positioned every four to six campsites along road shoulders.

Campers must inspect the faucet nozzle before attempting connection:

• Threaded spigots: Feature standard garden hose threads (GHT) permitting campers to screw on fresh water hoses for RV tank filling.
• Unthreaded spigots: Feature smooth, rounded metal spouts without threads. Agencies install unthreaded spigots intentionally to prevent campers from attaching permanent hoses and monopolizing water pressure or creating cross-contamination hazards.

Never leave a hose permanently attached to a communal spigot. Fill your containers or onboard tanks, then disconnect your gear immediately.

Working with unthreaded faucets: the Water Bandit

When visiting campgrounds equipped with smooth, unthreaded faucets, standard RV water hoses cannot screw on.

A specialized adapter known as a Water Bandit or Water Thief solves this problem:

• The device consists of a flexible, heavy-duty silicone sleeve with a female garden hose fitting on the opposite end.
• Slide the silicone collar over the smooth metal faucet nozzle. The rubber grips the metal pipe by friction.
• Connect your RV water hose to the threaded brass fitting.
• Open the water valve slowly at low pressure. Because the silicone relies on friction, high water pressure will blow the adapter off the faucet. Hold the collar in place while filling tanks.

This adapter allows RVers to fill freshwater holding tanks at facilities that prohibit direct hose screw-ons.

RV dump station etiquette and operational steps

Developed campgrounds that accommodate RVs frequently provide a central sanitary dump station near the entrance kiosk. Following sanitary protocols protects public health:

• Order of draining: Always connect your sewer hose firmly with an airtight donut or threaded elbow into the ground inlet. Drain the black water tank (toilet waste) first. Once empty, close the black valve and open the grey water tank (sink and shower waste). The soapy grey water rinses the sewer hose of sewage residue.
• Wash-down hose vs potable tower: Dump stations feature two separate water supplies. The non-potable hose mounted next to the ground drain is for flushing tanks and rinsing hoses. Never use this hose to fill drinking water tanks or rinse personal dishes. A separate potable fill tower, located at least 30 feet away, provides clean drinking water.
• Clean up the station: Wash down any accidental spills into the drain using the non-potable rinse hose. Replace the station sewer cap before pulling away.

Limit your time at the dump station to ten minutes when other rigs wait in line.

Seasonal freeze shutoffs and winter dry camping

Public campgrounds in mountainous and northern regions shut down water systems in autumn to prevent freezing temperatures from bursting underground pipes.

Seasonal water management:

• Shutoff dates: Water systems are typically drained and blown out with compressed air following Indigenous Peoples' Day / Columbus Day in mid-October, remaining offline until late May.
• Dry camping status: Campgrounds that turn off water often remain open for dry camping at reduced nightly rates. Flush toilets are locked, with facilities transitioning to primitive vault toilets.
• Frost-free spigots: Some four-season campgrounds maintain one centralized frost-proof hydronic spigot near the entrance station for emergency container fills during winter.
