Designing a septic system is about more than just digging a hole in the ground. In the Inland Empire, soil composition, property slope, and local environmental regulations play a massive role in whether your system will pass inspection and last for decades.

At Davis Plumbing, we specialize in professional septic system design that meets the specific needs of homeowners in the 951 area.

The Design Process

A successful septic installation starts with a plan. Here are the key factors we consider:

  1. The Percolation (Perc) Test: We must determine how quickly the soil on your property absorbs water. This dictates the size and type of drain field you need.

  2. Daily Water Load: A two-bedroom cottage requires a very different design than a five-bedroom family home.

  3. Property Topography: If your land is sloped, we may need to incorporate a septic ejector pump to ensure waste moves efficiently to the tank.

Types of Systems

Depending on your land, we might recommend:

  • Gravity Systems: The most common and reliable design when the land is flat.

  • Pressure Distribution Systems: Used when soil is thin or property lines are tight.

  • Alternative Systems: Necessary for properties near environmentally sensitive areas or with poor soil quality.

Why Professional Design Matters

A poorly designed system won’t just fail; it can lead to legal issues and massive fines. Proper septic system maintenance starts with a high-quality installation. Getting the design right the first time is the only way to avoid the massive cost to replace a septic drain field down the road.
