Spring Water vs. Well Water: Unique Dual-System Setup in Off-Grid Mountain Property

Welcome back to Base Camp WNC, where today we’re exploring a rare and clever off-grid water setup deep in the North Carolina mountains. This mountain property features a dual water system—one drawing from a natural spring water source, and the other from two drilled wells, all integrated into a backup-ready flow system.

Let’s take a closer look at how this works and what lessons you can take if you're setting up or buying rural property with alternative water sources.

🌿 Spring Water Source with Gravity-Fed System
This property is connected to a gravity-fed spring water system sourced from a neighbor’s land through a spring box and a 1,000-gallon underground concrete reservoir tank. The overflow from the spring flows downhill and is collected into a secondary 1,500-gallon storage tank, protected within a large retaining wall made of railroad ties.

• The overflow from the spring measures approximately 2.34 gallons per minute, enough to supply daily needs.
• The tank is designed with freeze prevention in mind—a must for cold-weather off-grid water storage.
• The float system inside this tank regulates when the backup wells kick in.

💧 Dual-Well Backup System: How It Works
Due to seasonal inconsistencies or past disrepair of the spring, two separate wells were drilled as backups:
Well #1:

• Rated at 4 gallons per minute (tag claimed 5 GPM).
• Connected through a water control float switch that activates when the spring-fed tank drops to about 250 gallons.
• Programmed with a 60-minute recovery timer to protect the pump and manage flow based on recharge rate.

Well #2:

• Produces around 0.7 gallons per minute.
• Configured to pump 9 gallons every 32 minutes, regulated by a timer and a float sensor.
• Also feeds the main reservoir, working in tandem with Well #1.

Combined, both wells deliver around 1,080 gallons per day, which is more than enough for typical household use, even in off-grid conditions.

Important Note: Improper sealing on one well casing allowed hornets to nest inside. Always ensure your well heads are sealed and secure—no duct tape shortcuts! This helps avoid insect infestation and maintains system integrity.

🚿 Water Filtration and Conditioning at the House
The water system enters the home through:

• A pressure tank.
• Water softeners and filters.
• A UV sterilizer, which, in this case, hasn't been serviced in a while (flashing red indicators).

The current owner has passed away, and new buyers unfamiliar with well or spring systems are stepping in. That’s why we’re documenting this—it’s a great learning tool for anyone investing in rural property or setting up an off-grid homestead water system.

🌄 Final Thoughts on Off-Grid Water in Mountain Properties
This setup is a smart example of redundancy in off-grid water supply systems—using both spring water and well water for reliability. It also highlights common issues like system neglect, unsealed wellheads, and shared spring rights.
If you're buying land in the mountains or planning to go off-grid:

• Understand where your water is coming from.
• Know the flow rates and storage capacity.
• Factor in seasonal use and whether your tanks are insulated or buried.
  
  
• Keep systems clean, sealed, and serviced.
