Do You Need a New Septic System?

There are a variety of reasons a homeowner may need a septic system installation in Ithaca, NY, including:


  • New Construction: If you're building a new home on land without access to municipal sewer, you'll need a fully functioning septic system to treat your household wastewater.
  • System Failure or Age: Older systems can crack, fail inspections, or simply wear out over time.
  • System Undersized for Current Use: If your household size has increased, your existing tank may not be large enough to keep up with your daily water usage.
  • Drainfield Issues: Drainfields that can no longer properly filter wastewater often require system replacement.


No matter the reason, the most important thing is choosing a knowledgeable team to do the job right. Clean Earth Septic provides full-service solutions, including system design, excavation, installation, inspections, and repair.

The First Step: Soil Testing and Permitting

Before any septic tank installation can begin, the land must pass a percolation test (or “perc test”). This test measures how well the soil can absorb and filter wastewater. Soil with sand or gravel tends to drain well, while clay-heavy soil may fail.


If you're planning a septic system installation in Ithaca, NY, a perc test is required by your local health department and should be completed before buying land, especially for residential development. Once your site passes the test, Clean Earth Septic can help you obtain the proper permits and recommend a system type that meets both your soil’s requirements and your household’s needs.


Excavation and Site Preparation

After the soil testing and permit process is complete, it’s time to prepare the site. This is where Clean Earth Septic really shines. Unlike many other companies, we don’t subcontract our excavation services. Our in-house team performs all site prep work, including:


  • Excavating for septic tanks and drainfields
  • Digging trenches for sewer lines or underground utilities
  • Grading to address drainage issues
  • Bulldozer and backhoe services


Handling excavation ourselves allows us to offer reasonable rates, efficient scheduling, and greater quality control for your Ithaca, NY septic service. If your home is already built, we’ll work carefully to minimize yard damage during digging. If your home is under construction, we’ll coordinate with your general contractor to time the dig appropriately—usually after the home’s frame is up but before final hardscaping or driveways are installed.

Choosing the Right Septic System and Tank

Once the site is prepared, we’ll help you determine which system is the best fit for your property. There are several types of septic systems used in septic system installations in Ithaca, NY, including:


  • Conventional Gravity Systems: Best for properties with well-draining soil and sufficient space for a drainfield.
  • Pressure Distribution Systems: Used where even distribution of wastewater is needed across the drainfield.
  • Mound Systems or Sand Filters: Ideal for properties with shallow soil or high water tables.
  • CIPP No-Dig Sewer Line Repairs: A trenchless option used in some repair scenarios where replacing old lines without excavation is possible.


When it comes to septic tank installation, tank material matters. Here’s a breakdown of the most common tank types we install:


  • Concrete Tanks: Long-lasting and rust-proof, but heavy and difficult to repair if damaged.
  • Plastic Tanks: Lightweight and affordable, but more susceptible to cracking or crushing.
  • Fiberglass Tanks: Stronger than plastic and rust-resistant, though they can be shifted by groundwater pressure.


Our team will assess your perc test results, property layout, household size, and budget to help you choose the right combination of tank type and system layout.


Full-Service Installation from Start to Finish

Clean Earth Septic manages the entire septic system installation in Ithaca, NY process—from ground prep to final hookup. Our services include:


  • Excavation for the tank, drainfield, and piping
  • Installation of the septic tank, filtration system, and distribution box
  • Connecting piping and plumbing components
  • Backfilling and grading
  • Final inspection and permit approval


We also offer distribution box replacement, sewer line repairs and replacements, and drainfield rejuvenation services. This means we’re equipped to handle any unexpected issues that might arise during installation, saving you time, hassle, and money.

Don’t Forget the Drainfield

Your drainfield (also known as a leach field) is just as important as the tank itself. It filters and purifies wastewater before it reenters the groundwater. A properly built and maintained drainfield can last decades, while a poorly managed one can lead to system failure and costly repairs.


If a full replacement isn't necessary, we offer drainfield rejuvenation—a service that uses high-pressure jetting and vacuum trucks to clear out buildup in the lines. This can extend the life of your system and save you from installing a new drainfield.


Septic Tank Installation as an Investment

A high-quality septic tank installation may seem like a large upfront investment, but it's one that pays off in reliability, compliance, and peace of mind. If done improperly, you risk system backups, water contamination, failing inspections, and costly future repairs.
