Quick Answer
A PVC well casing can cost between $15 and $30 per foot, while a steel well casing typically ranges from $10 to $25 per foot, depending on the material thickness and diameter. However, PVC casing is more prone to damage and lifespan limitations compared to steel.
Material Comparison
When it comes to well casing materials, PVC (polyvinyl chloride) and steel are two popular choices. While PVC is a more affordable option, it’s not ideal for deep or heavy-duty wells due to its relatively short lifespan and susceptibility to damage from chemicals, abrasion, and sunlight. On the other hand, steel well casing is more durable and long-lasting, with a typical lifespan of 50 to 100 years or more, depending on the material thickness and environmental conditions.
Cost Breakdown
To better understand the cost difference between PVC and steel well casing, let’s consider a typical well depth of 200 feet. A 6-inch PVC casing would cost around $3,000 to $6,000, while a 6-inch steel casing would cost between $2,000 to $5,000. For larger diameters or deeper wells, the cost savings of steel casing become more pronounced. For example, a 12-inch PVC casing for a 400-foot well would cost around $24,000 to $48,000, whereas a 12-inch steel casing would cost between $16,000 to $32,000.
