Guide to Septic System Installation

April 11, 2025

Installing a septic system is an important investment for any property not connected to a municipal sewer system. A properly installed system ensures efficient wastewater management, protects the environment, and supports the long-term functionality of your home. Understanding the installation process and the cost to install a septic system can help homeowners make informed decisions.


At Drainfield Solutions, we have been providing expert septic system installation, septic tank maintenance, and septic drainfield repairs since 2005. Serving Central Virginia, we take pride in delivering reliable and eco-friendly wastewater solutions tailored to each property’s needs. 


Step-by-Step Guide to Septic System Installation

1. Site Evaluation and Permits

A professional site evaluation is necessary to determine the best location for your septic system. Factors such as soil type, water table levels, and available space influence the type of system needed. If soil conditions are not ideal, alternative septic systems such as an aerobic septic system or a mound system may be required.


Local health department permits must be obtained before installation. Regulations vary by location, and Drainfield Solutions in Central Virginia ensures compliance with all necessary requirements in Virginia.


2. Choosing the Right Septic System

The best septic system depends on property conditions and household needs. Common options include:

  • Conventional Septic System: A septic tank and drainfield that naturally filters wastewater.
  • Aerobic Septic System: Uses oxygen to break down waste efficiently, suitable for properties with poor soil absorption.
  • Mound System: A raised drainfield designed for areas with shallow soil or high water tables.
  • Drip Distribution System: Distributes wastewater through a network of pipes in areas with challenging terrain.


Selecting the right system affects overall installation costs and long-term performance.


3. Excavation and Septic Tank Installation

Excavation is required to prepare space for the septic tank and drainfield. The septic tank, made of concrete, fiberglass, or polyethylene, is placed carefully to ensure proper wastewater flow. Concrete tanks offer durability, while fiberglass and polyethylene options are lighter and easier to install but require anchoring to prevent shifting.


4. Installing the Drainfield

The drainfield disperses treated wastewater into the soil. Proper site selection ensures effective filtration and prevents groundwater contamination. Soil composition plays a significant role in drainage performance, and adjustments may be needed to optimize system function.


5. System Connection and Testing

After installation, the system is connected to the home’s plumbing. Final inspections ensure proper function, and approval from local authorities may be required before use.


Septic System Maintenance for Longevity

Routine maintenance prevents costly septic system problems. Key steps include:

  • Septic Tank Pumping: Tanks should be pumped every 3-5 years to remove solid waste buildup.
  • Water Conservation: Excessive water usage can overload the system. Spread out laundry loads and repair leaks.
  • Proper Waste Disposal: Avoid flushing grease, wipes, and chemicals that can damage the system.
  • Regular Septic Tank Inspections: Annual inspections identify potential issues before they become major repairs.

For real estate agents working in Central Virginia—whether you specialize in Fredericksburg, Spotsylvania County, or rural Caroline County—understanding the evolving world of septic system inspections is no longer optional. With new regulations going into effect on July 1, 2025 , real estate septic inspections are about to become a more formalized and regulated part of your transaction process. Thanks to HB2671 , any real estate septic inspection conducted in connection with a real estate sale in Virginia must follow specific legal standards. The new law regulates how inspections must be conducted when they occur . In this blog, we’ll outline 10 professional steps real estate agents in Central Virginia should follow to ensure smooth, legal, and successful real estate septic inspections . Whether your listing is in Stafford County, King George, or Culpeper, these steps will keep your deal compliant—and your clients confident. 1. Know the Law: HB2671 Is About Standards I f a septic real estate inspection is performed during the sale, it must comply with the new Virginia Real Estate Septic System Inspection Contract , which: Defines the required scope of the real estate septic inspection Restricts who may perform the real estate septic inspection Requires a formal, written report Outlines what inspectors must (and must not) do The full legislation is designed to protect buyers, sellers, and agents by standardizing what was once an unregulated and inconsistent process. 📖 Read more about HB2671 here (Virginia General Assembly) 2. Educate Clients Early A critical success factor is proactive communication . As soon as you know a property uses a septic system , inform your clients: That routine septic maintenance is often expected by buyers That a real estate septic inspection , may be recommended by lenders, attorneys, or buyers That if the inspection occurs, it must follow HB2671 standards Don’t let confusion derail negotiations. Clear expectations reduce surprises and build trust. 3. Use the Official Contract Starting July 1, 2025, every septic inspection tied to a real estate transaction must use a real estate septic inspection contract . This document is: A legal contract between the inspector and the client (buyer, seller, or agent) Required to ensure the inspection meets state-defined minimum standards Designed to define roles, limit liability, and protect all parties ✅ Pro Tip : Include the contract in your transaction packet or closing checklist to ensure your buyer or seller signs off in advance. 4. Choose the Right Inspector Not just any septic contractor can perform a real estate inspection under HB2671. The inspector must be licensed by the Virginia Department of Professional and Occupational Regulation (DPOR) and hold one of the following credentials: Onsite Sewage System Operator Onsite Sewage System Installer Onsite Soil Evaluator Using an unqualified provider can delay closing or invalidate the inspection report altogether. 🎯 Use the DPOR License Lookup Tool to confirm credentials. 5. Book Inspections Early in the Timeline With rising demand and stricter regulations, last-minute scheduling won’t cut it . In fast-moving markets like Fredericksburg and Mechanicsville, agents should: Book the real estate septic inspection immediately after the contract is ratified Ensure inspectors are available within the contract timeframe Build a 10-day window for the report (as required by law) Remember, under HB2671, the inspector has 10 calendar days to deliver a written report. 6. Understand What’s Included—and What’s Not Per the new contract, inspections are visual and non-invasive . They do not include: Hydraulic load tests Digging into inaccessible areas Pass/fail determinations However, they must include readily accessible components, as long as not obstructed, such as: Septic tanks Pump tanks Distribution boxes Control panels Treatment units Dispersal (drain) fields Grading and vegetation observations 📌 Important : The inspection must not rely on rod-and-probe-only methods , which are now deemed insufficient. 7. Review the Real Estate Septic Inspection Report Thoroughly Real estate agents should read and understand the written report before forwarding it to clients. The report must include: Inspector’s name, license number, and signature Components inspected and any that were inaccessible Observed issues or failures Repair or health department referral recommendations If the inspector’s report is vague or incomplete, you risk deal delays or disputes later. 8. Guide Buyers on Next Steps If the real estate septic inspection report identifies septic system issues —especially with critical elements like the drainfield or septic tank—your buyers will look to you for guidance. Be ready to: Recommend follow-up with a licensed installer or repair professional Help estimate potential drainfield repair costs Adjust contract terms or repair requests accordingly 9. Help Sellers Prepare On the listing side? Savvy agents encourage pre-sale inspections for septic systems—especially older ones. Why? It prevents unpleasant surprises It gives sellers time to make repairs on their terms It builds buyer confidence Sellers in areas like Dahlgren , Ruther Glen , or Aylett can benefit greatly from a clean inspection report in the listing process. 10. Partner with a Reliable Septic Pro Finally, build relationships with trusted septic professionals who: Understand the intricacies of HB2671 Are fully licensed and insured Provide fast turnaround and excellent communication Offer additional services like septic pumping, drainfield repair, and emergency service A reputable company like Drainfield Solutions ensures your transactions stay on track while giving your clients peace of mind.

According to the National Association of Realtors , agents who anticipate potential system problems and navigate them proactively are far more likely to close quickly—and earn client referrals.
