What Is a Water Cistern?

A cistern is a sealed water storage tank used to hold potable water for residential use. In the San Luis Valley, cisterns are most commonly used as part of a hauled water storage system, supplying homes where wells are unavailable, unreliable, or impractical.

While cisterns can be used for rainwater collection in some regions, annual rainfall in this area is typically insufficient to rely on rainwater alone. For this reason, most cistern systems we install are designed specifically for truck-delivered potable water, with durability, freeze protection, and ease of access in mind.

Modern systems typically use underground potable water cisterns, which protect stored water from freezing temperatures, sunlight exposure, and surface contamination. These systems are also commonly referred to as underground water storage tanks.

Our Cistern Installation Process

Our water cistern installation process is designed specifically for rural and high-elevation properties common in and around Alamosa.

Each installation includes:

  • Excavation and site preparation

  • Placement of a buried potable water cistern

  • Installation of a 1″ PEX water line run directly to the home’s foundation

  • Proper backfilling and site restoration

We install water storage tank systems that integrate cleanly with residential plumbing and work seamlessly with new or existing septic systems. Whether you’re storing hauled potable water or planning limited supplemental rainwater collection, our installations are completed with long-term reliability in mind.

Underground vs. Above-Ground Cisterns

Most of the systems we install are underground potable water cistern tanks designed for hauled water storage. Underground installation offers several advantages:

  • Improved freeze protection

  • Reduced algae growth

  • Long-term durability

  • A clean, unobtrusive appearance

While above-ground cisterns are available, underground tanks are typically the best option for residential properties in Alamosa due to climate conditions, space considerations, and long-term performance.

Cistern Sizes We Install

We install two standard potable cistern sizes commonly used for full-time residences:

  • 1250-gallon rainwater cistern

  • 1750-gallon rainwater cistern tank

These tank sizes are well suited for homes using hauled water and can be installed efficiently as part of new construction or retrofitted for existing homes. They also pair well with septic system installations completed at the same time.

Water Cistern Installation Cost

We believe in clear, upfront pricing so property owners know exactly what to expect. The pricing below reflects typical water cistern installation cost for properties in Alamosa, with service available throughout the San Luis Valley.

  • Standalone installation: $3,750

1750-Gallon Underground Cistern
