A large water storage system solves the gap between what your well produces and what your property demands. If your well makes 3 GPM but you need 15 GPM during peak hours — feeding livestock, running sprinklers, and showering at the same time — a storage tank lets the well fill slowly around the clock while a booster pump delivers water at the flow rate you actually need.

Legacy Water Well designs and installs storage systems from 500 to 10,000 gallons across North Texas. These systems are common on:

• Cattle ranches and horse properties — Livestock demand is constant and unpredictable. A 2,500-gallon tank ensures water availability even during drought conditions when well levels drop.
• Large rural estates — Properties with a main house, guest house, barn, and irrigation on a single well. Storage provides the capacity a standard pressure tank cannot.
• Low-yield wells — Some North Texas wells produce only 1–3 GPM. That is enough to fill a large tank overnight, but not enough to run a household during the day without storage.
• Agricultural operations — Irrigation, wash-down, dust suppression, and other commercial water needs that require high-volume delivery.
• Fire suppression reserves — Rural properties without fire hydrant access use storage tanks as a reserve for fire departments. Many insurance companies offer discounts for properties with dedicated water reserves.

We install three types of storage tanks depending on your property, budget, and water quality needs:

Polyethylene (poly) tanks — The most popular choice for residential and ranch applications. Black or dark green poly tanks resist UV degradation and algae growth. Available from 500 to 10,000 gallons. Lightweight, durable, and cost-effective. These are what we install on 90% of storage projects.

Fiberglass tanks — Stronger and more resistant to chemicals than poly. Used for properties with aggressive water chemistry or where tanks are partially buried. More expensive but longer-lasting in harsh conditions.

Concrete cisterns — For permanent, high-capacity installations where aesthetics matter or the tank needs to be underground. Less common due to cost, but appropriate for specific applications.

Common sizes we install:

• 500–1,000 gallons — Small properties, backup reserves, and low-yield well supplements. Good for homes with 1–3 GPM wells.
• 1,500–2,500 gallons — The sweet spot for most ranch homes with livestock. Provides a full day of reserve for a 3-bedroom home plus moderate livestock demand.
• 3,000–5,000 gallons — Larger ranches, multi-building properties, and properties with irrigation needs.
• 5,000–10,000 gallons — Commercial agriculture, large cattle operations, and properties requiring fire suppression reserves.

A storage tank system is more than just a big tank sitting on the ground. It is a complete water management system designed around your well's production and your property's demand. Here is how we approach it:

1. Well production assessment — We measure your well's sustained GPM output and recovery rate over an extended pump test. This tells us how much water your well can realistically produce in 24 hours.
2. Demand calculation — We add up household demand, livestock needs, irrigation, and any other water uses. Peak demand versus average demand determines the tank size and booster pump specification.
3. Site selection and preparation — The tank needs a level, compacted pad that can support the full weight (a 2,500-gallon tank full of water weighs over 20,000 lbs). We coordinate site prep and verify access for delivery equipment.
4. Tank placement and plumbing — The well pump feeds the tank through a float valve that shuts off at full capacity. The booster pump draws from the tank and feeds the pressure tank and house plumbing at the required flow rate.
5. Controls and protection — Low-level cutoff switches protect the booster pump from running dry. Overflow provisions prevent flooding if the float valve sticks.
6. System testing — We run the complete system through fill, draw-down, and recovery cycles to verify everything works together correctly.
