Sand and Silt in Your Well? What Kings and Tulare County Water Does to Your Pump
If you farm or live on acreage in Woodlake, Lindsay, or Porterville, you are intimately familiar with the “grit.” We constantly hear from farmers who are frustrated that their pumps keep wearing out faster than they should. They replace the equipment, and six months later, they’re right back where they started. The core question is: “Why does my pump keep wearing out faster than it should?” The answer is almost always the same: your well is pulling fine sediment from the alluvial soils of the eastern valley floor.
The Problem with Alluvial Soil
The San Joaquin Valley was formed by sediment washing down from the Sierras over millions of years. This sediment doesn’t always settle into nice, clean rock layers. In areas like Woodlake, Lindsay, and Porterville, many wells are pulling from “unconsolidated” layers—essentially thick beds of fine sand and silt.
When your pump draws water from these sandy aquifers, it’s also drawing in fine abrasive particles. Even if your screen is doing its job, fine sand can bypass it and get pulled into the pump’s intake. Once that grit enters the pump, it acts like sandpaper on your impellers and seals. It doesn’t cause an immediate explosion; it causes a slow, agonizing death for your pump. Over time, that sand eats away at the precision-engineered parts, reducing pressure, increasing power consumption, and eventually forcing a complete replacement.
When to Use a Sand Separator
If you are burning through pumps, you need to stop just replacing the pump and start addressing the sediment. A sand separator is a piece of equipment that forces the water to spin rapidly as it enters the system. The centrifugal force throws the heavier sand particles to the outside of the chamber, where they fall into a collection vessel, leaving cleaner water to continue through your pump.
However, a sand separator isn’t a magic wand. If your well is producing massive amounts of sand, the well itself might have a collapsed screen or a casing issue. In those cases, a separator will fill up instantly, and you’ll be back to square one. Sometimes, the right move is to have an expert perform a down-hole camera inspection to see if the well screen has failed and requires rehabilitation before you invest in more equipment.
If you’re in Woodlake, Lindsay, or Porterville and burning through pumps, we can diagnose why.
Frequently Asked Questions
What causes sand in my well water?
Many wells in areas like Woodlake, Lindsay, and Porterville draw from unconsolidated alluvial sediment layers. If the well screen is damaged or improperly sized, this fine sediment can be drawn directly into your pump intake.
Will a sand separator solve my pump problems?
A sand separator can be highly effective in removing abrasive silt before it enters the pump. However, if the issue stems from a collapsed well screen, the separator will quickly fill, so a diagnostic inspection is often necessary.
Should I call a professional if I see sand?
Yes, you should contact Ingram Pump immediately. Sand acts like an abrasive that will rapidly destroy your pump's impellers and seals, leading to total pump failure and potential damage to your well screen.
