Why Choose Our Cesspool to Septic System Conversion
Cesspool to septic system conversion is a significant investment in your property, your groundwater, and your family’s health. Action Septic Service brings decades of field experience to every conversion project we take on.
We’re a licensed, insured septic contractor with a dedicated team of operators, excavators, and septic engineers who specialize in replacing obsolete cesspools. Our crews have converted hundreds of deteriorated seepage pits and drywells into fully compliant onsite wastewater treatment systems. We don’t subcontract the work. We own our own backhoes, excavators, trenchers, and vacuum trucks.
Every cesspool conversion we perform starts with a thorough site evaluation. We conduct perc tests, measure setbacks from property lines and wells, assess the water table depth, and design a system that fits your lot. We work directly with your local health department to secure permits and schedule inspections.
Our pricing is transparent. You’ll receive a detailed written estimate that covers cesspool abandonment, tank installation, distribution box placement, drainfield construction, backfill, grading, and final inspection. No surprise charges. No hidden fees.
Action Septic Service stands behind every conversion with a workmanship guarantee. We’re the trusted, top-rated choice for homeowners who need their cesspool replaced with a modern, engineered septic system.
Signs You Need Cesspool to Septic System Conversion
Cesspool to septic system conversion is the right solution when your existing cesspool can no longer safely treat and disperse wastewater. Here are five signs that your cesspool has reached the end of its service life.
Persistent Sewage Odors Near the Cesspool: A failing cesspool releases hydrogen sulfide and other gases through saturated soil. If you smell sewage in your yard, near your foundation, or around the cesspool access lid, the structure has likely lost its ability to leach effluent into surrounding soil. The biomat layer at the bottom may be completely clogged.
Standing Water or Soggy Ground Above the Cesspool: When a cesspool can’t absorb wastewater fast enough, effluent seeps to the surface. You’ll notice wet, spongy patches of grass or pooling greywater directly above the pit. This overflow poses a direct pathogen and coliform contamination risk.
Slow Drains and Backed Up Fixtures: Toilets that flush sluggishly, sinks that drain slowly, and tubs that hold standing water all point to a cesspool that’s reached capacity. Snaking or jetting the inlet pipe provides only temporary relief when the cesspool walls are corroded and the soil is saturated.
Health Department Notice or Failed Title V Inspection: Many municipalities now require cesspool conversion as a condition of property sale or upon discovery of a non-compliant system. A failed Title V inspection means your cesspool doesn’t meet current wastewater treatment standards.
Elevated Nitrate or Coliform Levels in Well Water: If your well water tests show rising nitrate concentrations or coliform bacteria, your cesspool may be contaminating the groundwater. Cesspools lack the biological treatment stages that a properly designed septic tank and drainfield provide. Converting to a septic system adds critical treatment layers that protect your drinking water supply.
Our Cesspool to Septic System Conversion Process
Cesspool to septic system conversion is a multi-phase project that follows a precise sequence. Here’s how Action Septic Service completes every conversion from start to finish.
Step 1: Site Evaluation and Soil Testing — We visit your property, locate the existing cesspool, and conduct a percolation test. We measure the soil percolation rate, identify the water table depth, and document all setbacks from wells, property lines, and easements.
Step 2: System Design and Permitting — Our septic engineer designs a new system based on your soil test data, bedroom count, and estimated hydraulic load. We submit the engineered plans and permit application to your local health department.
Step 3: Cesspool Decommissioning — Once the permit is approved, our vacuum truck pumps and removes all sludge, scum, and residual sewage from the old cesspool. We then collapse, fill, and seal the structure with approved aggregate and clean fill material.
Step 4: Excavation and Tank Installation — Our backhoe and excavator crew digs the new tank pit and drainfield trenches. We set the precast concrete or fiberglass septic tank, install the inlet and outlet pipes, connect the distribution box, and lay out the leach field laterals with proper gravel bed and geotextile fabric.
Step 5: Connection, Backfill, and Inspection — We connect the home’s sewer line to the new septic tank, install risers and the effluent filter, backfill all excavations, and grade the site. The health department sanitarian inspects the system before final cover. You receive your certificate of compliance and a complete as-built drawing.

FAQs About Cesspool to Septic System Conversion
What is a cesspool to septic system conversion?
A cesspool to septic system conversion is the complete replacement of an old, single-chamber cesspool with a modern septic tank and drainfield. The cesspool gets pumped, collapsed, and sealed. A new septic tank, distribution box, and leach field are installed to properly treat and disperse household wastewater through biological decomposition and soil absorption.
When should I convert my cesspool to a septic system?
You should convert when your cesspool shows signs of failure — sewage odors, surface overflow, backed-up drains, or contaminated well water. Many states and municipalities now mandate conversion during property transfers or when a cesspool is within a certain distance of groundwater or coastal resources.
How long does a cesspool to septic conversion take?
Most residential conversions take five to ten working days from excavation to final inspection. Permitting and soil testing add two to six weeks before ground is broken. Weather, site conditions, and health department scheduling can affect the timeline.
How much does it cost to convert a cesspool to a septic system?
Costs vary based on system type, soil conditions, tank size, and drainfield configuration. A conventional gravity-fed system costs less than a mound system or pressurized drainfield. Action Septic Service provides detailed written estimates with no hidden charges.
Can I keep using my cesspool instead of converting?
In many jurisdictions, you cannot. Health departments are phasing out cesspools because they discharge untreated sewage directly into the ground. Cesspools lack the baffles, effluent filters, and drainfield treatment stages that protect groundwater from pathogens, nitrates, and phosphorus contamination.
Does a cesspool conversion require a permit?
Yes. Every cesspool to septic system conversion requires a permit from your local health department. The permit process includes a soil and percolation test, an engineered system design, and inspections at multiple stages of construction. Action Septic Service manages the entire permitting process for you.
