The Complete Homeowner’s Guide to Septic System Installation in Richmond, VA (Types, Costs & Process)
Written by the licensed professionals at RVA Site Services - proudly serving Amelia, Chesterfield, Powhatan, and Central Virginia.
If you’re a homeowner in Richmond, VA—or anywhere in the surrounding counties—you’ve likely heard at least one neighbor mention septic issues, drain field problems, or the cost of installing a new system. Septic systems aren’t flashy, but they’re one of the most important parts of your home’s infrastructure, especially if you’re outside city sewer lines.
At RVA Site Services, we’ve spent more than 20 years installing, repairing, pumping, and maintaining septic systems across Greater Richmond. This guide breaks down everything a homeowner needs to know before starting a septic installation project—types of systems, costs, permits, timelines, and how the whole process works from start to finish.
Whether you're building a home, replacing a failing system, or just preparing for the future, this is your go-to resource.
What Is a Septic System and Why Do You Need One?
A septic system treats wastewater from your home when you don’t have access to a municipal sewer connection. Every time you flush a toilet, run a washing machine, or take a shower, that wastewater needs to go somewhere—and your septic system handles it onsite.
A complete system includes:
- A
septic tank
- A
drain field (leach field)
- Distribution lines
- Soil absorption area
- Optional pumps or treatment units
Richmond, VA has a mix of soil types—clay, loam, sand—and varying water tables, which means choosing the right system and installer is critical.
Types of Septic Systems Used in Richmond, VA
Every property is different, so not all systems work everywhere. Here are the main options in our area:
1. Conventional Gravity Septic System
This is the most common system:
- Requires good soil drainage
- Uses gravity to move wastewater
- Lower maintenance
- Ideal for neighborhoods with ample yard space
2. Aerobic Septic System
Perfect for challenging soil or small lots.
- Uses oxygen to break down waste faster
- Requires electricity
- Has mechanical parts
- Often needed in parts of Chesterfield, Powhatan & Amelia
RVA Site Services is licensed to install all aerobic systems, including alternative units.
3. Alternative/Advanced Septic Systems
These are required when a property fails traditional soil testing.
Examples:
- Sand mound systems
- Pressure-dosed systems
- Drip dispersal systems
- ATUs (Aerobic Treatment Units)
Because RVA Site Services holds an Alternative Master Installer License, we can install any system Virginia requires.
Step-by-Step: How Septic System Installation Works in Richmond, VA
Many homeowners think tanks are just buried underground and connected to pipes. The truth is far more detailed.
Here’s what actually happens:
1. Soil Testing (“Perk Test”)
A licensed evaluator checks:
- Soil type
- Drainage ability
- Water table depth
- Slope
- Required drainfield size
Richmond and surrounding counties (Amelia, Goochland, Powhatan, Chesterfield) all require this.
2. Septic System Design
A certified designer creates a layout for:
- Tank size
- Trenches
- Distribution lines
- Drainfield
- Elevations
- Pump requirements (if needed)
This design is submitted to the county with permit applications.
3. Excavation & Site Preparation
RVA Site Services handles all groundwork:
- Clearing
- Grading
- Digging trenches
- Ensuring proper slope levels
Since we own our excavators, dozers, and grading equipment, jobs move faster and more efficiently.
4. Tank & Component Installation
We install:
- The septic tank
- Inlet and outlet pipes
- Distribution boxes
- Drainfield trenches
- Pumps or ATU units (if required)
The tank is carefully leveled, connected, and stabilized.
5. County Inspection
Each installation must pass a final inspection before use.
Our team coordinates everything so homeowners don’t have to.
6. Backfilling & Final Grading
Proper backfill ensures:
- No settling
- No drainage issues
- A clean, finished appearance
We also discuss long-term maintenance and provide pumping schedules.
