Why You Should Do A Septic Plan Before Floor Plan Or Building

  • 3 min read

Embarking on a new construction project comes with a myriad of considerations, and one of the most critical aspects is the planning of waste and septic systems. Whether connected to a municipal sewer or requiring a dedicated septic system, careful planning in advance is essential to avoid future challenges. In this blog, we will delve into the intricacies of septic planning, site layout, and the crucial role it plays in the overall construction process.

Understanding Septic Systems

In areas without a municipal sewer system, a septic system becomes a necessity. The septic system typically consists of a septic tank and a drain field. The septic tank receives wastewater from the house, allowing solids to settle at the bottom while allowing liquid to flow into the drain field. Understanding the components and planning their placement is crucial for an efficient and trouble-free system.

Components of a Septic System

  1. Septic Tank: The initial point where wastewater enters the system. It separates solids from liquids, creating a scum layer on top to ensure only clearer water exits.
  2. Drain Field: A designated area where liquid effluent from the septic tank is treated by filtering through layers of soil. Proper setbacks and design are vital for its effectiveness.

Planning the Septic System

Site Plan Considerations

Before laying out the house or other structures, it’s crucial to plan the septic system. Here are key considerations:

  • Setbacks: Ensure the septic system is a sufficient distance from the house, property lines, and any escarpments. Setbacks are crucial for compliance with jurisdictional regulations.
  • Accessibility: Plan for easy access to the drain field with equipment, both during construction and potential future maintenance.
  • Evaporation Space: Avoid building driveways, decks, or structures over the septic system, as it requires open space for evaporation.

Designing the Drain Field

  • Length Requirements: The length of drain field pipes is determined by the number of bedrooms in the house. Adequate space must be allocated to meet these requirements.
  • Drop and Gravity: Consider the necessary drop from the septic tank to the drain field, often specified as inches per feet. Gravity is crucial for proper wastewater flow.
  • Repair Area: Many jurisdictions require a designated repair area in case of drain field failure, emphasizing the importance of forward-thinking in design.

Soil Considerations

  • Mound Systems: In cases where the soil has poor drainage, a mound system with added sand may be necessary to ensure proper treatment before reaching natural topsoil.
  • Trench Digging: Trenches for drain fields must be dug during dry conditions to prevent mud coating, which can impede drainage.

Collaborating with a Qualified Septic Installer

Working with a qualified septic installer is essential for creating an efficient and valuable system. Collaborating with architects and considering the overall property layout ensures that the septic plan complements the entire construction project.

Preserving Long-Term Value

Septic planning is a fundamental step in any construction project. Neglecting this aspect can lead to significant challenges in the future, impacting property value, resale potential, and overall functionality. By incorporating septic considerations into the initial site plan, property owners can ensure a resilient and efficient system that stands the test of time. For detailed insights and options, consult a qualified septic installer to create a design that aligns with your property’s unique characteristics and future needs.
