ABOUT SEPTIC SYSTEM DESIGN IN LOGAN, UT

Septic systems are on-site wastewater treatment systems commonly used in areas without centralized sewer systems, such as rural or suburban areas. They are designed to treat and dispose of household wastewater from toilets, showers, washing machines, and sinks.

A typical septic system consists of several components:

  • Septic Tank: The septic tank is a large, watertight container buried underground. It receives raw wastewater from the house and allows solids to settle at the bottom, forming sludge, while oils and grease float to the top as scum. Bacteria inside the tank help break down the solids.
  • Distribution Box: From the septic tank, liquid wastewater flows into a distribution box, which evenly distributes the effluent (liquid waste) to a network of perforated pipes in the drain field.
  • Drain Field (Leach Field): The drain field is a series of perforated pipes laid in trenches filled with gravel. The effluent from the septic tank is distributed through these pipes and percolates into the soil. The soil acts as a natural filter, removing harmful bacteria, viruses, and nutrients from the wastewater before it reaches the groundwater.
  • Soil: The soil beneath the drain field provides the final treatment and disposal of the effluent. It filters and purifies the wastewater, making it safe to enter the groundwater system.

OUR SEPTIC SYSTEM DESIGN PROCESS

In order to install a septic system on your property, you must first obtain a permit from the local health department. The design of septic systems in Utah is typically overseen by the Utah Department of Environmental Quality (DEQ), specifically the Division of Water Quality (DWQ) and local health departments. The design must be completed by a professional that is certified by the DEQ. Civil Solutions Group is certified by the DEQ to complete Level 1 (soil evaluation and site assessment) and Level 2 (system design) for conventional septic systems.

key aspects we consider in the design of septic systems in Logan, UT:

  • Soil Evaluation (Level 1): Before designing a septic system, a soil evaluation is conducted to assess the soil’s percolation rate, texture, and depth to determine its ability to absorb and treat wastewater. This evaluation helps in selecting an appropriate location for the drain field.
  • Site Assessment (Level 1): A site assessment is conducted to determine the best placement for the septic tank and drain field. Factors such as soil type, groundwater levels, slope of the land, and proximity to wells and water bodies are considered during this assessment.
  • Tank Sizing (Level 2): The septic tank size is determined based on the number of bedrooms in the house or the daily wastewater flow. Proper sizing ensures that the septic tank can hold the wastewater long enough for solids to settle and be partially broken down.
  • Drain Field Design (Level 2): The drain field design includes the layout and size of perforated pipes, as well as the type and depth of the gravel bed. The design aims to evenly distribute the effluent over a large area, allowing it to be naturally filtered and treated by the soil.
  • Setback Distances (Level 2): Septic systems must adhere to setback distances, which specify the minimum distances required between the septic components (such as tanks and drain fields) and property lines, wells, surface water bodies, and buildings. These distances help prevent contamination of water sources and neighboring properties.
  • Regulations Compliance (Level 2): Designs must comply with state and local regulations, which may vary based on the specific county or municipality within Utah. It’s important to adhere to these regulations to obtain necessary permits for septic system installation.
