What We Do
Official Massachusetts Title 5 septic inspections performed in accordance with state requirements — for real estate transactions, property transfers, and compliance situations requiring a formal inspection report. Accurate field evaluation, clear documentation, and reporting.
Best for: Sellers, buyers, realtors, attorneys, and property owners needing an official report.
Informal, non-regulatory system evaluations designed for property owners who want a better understanding of system condition before triggering an official Title 5 inspection process. These evaluations do not produce a state inspection report, but they help identify concerns and support maintenance planning.
Best for: Homeowners planning ahead, pre-listing evaluations, inherited properties, and maintenance concerns.
Maintenance-focused inspections, component checks, informal system reviews, and practical onsite wastewater support for homeowners who need answers about system condition, maintenance, and function.
Best for: Owners who are not necessarily selling but need answers before problems become expensive.
Scheduled oversight for Innovative/Alternative systems that require ongoing maintenance: control panel and alarm inspection, pump and float testing, blower review, treatment component evaluation, effluent filter service, drainfield observation, and required O&M documentation.
Best for: I/A system owners, property managers, commercial properties, and permitted systems requiring ongoing maintenance.
Construction-phase stormwater inspections, field documentation, erosion and sediment control observations, site monitoring, and compliance support throughout construction.
Best for: Contractors, developers, property owners, and construction projects.

What to Expect
Most inspections take one to two hours, though time varies with system type, site conditions, access, and weather. Proper inspections are not rushed.
Every inspection follows the flow of the system — from the building sewer to the tank, the distribution box, and the leaching field.
We locate the septic tank, distribution box, and leaching field, then uncover the components needed for an accurate evaluation.
The tank is opened and examined for condition and structure, inlet and outlet baffles, liquid levels, and any signs of backup or improper flow.
We verify that the distribution box is level and distributing water properly so wastewater reaches the leaching field evenly.
The field is assessed for signs it may not be draining correctly — surface water or unusual odors that indicate improper absorption.
Water from the home is run through the system so we can observe how wastewater actually moves through the tank and distribution components.
We review pumping and maintenance records when available, determine Pass, Conditional Pass, or Fail, and deliver a complete written report submitted to the local Board of Health.
Straight Answers
$400 – $800
Typical range for a Title 5 inspection. Pumping, excavation of buried components, and any repairs found are separate costs.
Larger systems take more time to locate, open, and evaluate.
Bedroom count sets the design capacity the system is measured against.
Older systems and missing records require more investigation on site.
Property access and where you are in Massachusetts both affect the final price.
About Us
Onsite Wastewater Inspections LLC is a family-owned company serving the South Shore of Massachusetts. Before becoming a certified inspector, our founder worked directly in the field installing onsite wastewater systems throughout Massachusetts.
Many septic inspections are performed by companies whose primary business is pumping, repairs, or installation. We do not install and we do not repair — which is exactly why homeowners, buyers, and agents can trust that what is in the report is simply what is in the ground.

We explain findings clearly so you understand the condition of your system.

Local knowledge matters: we understand regional soil conditions, system types, and Board of Health procedures.
