Septic Services
Our Septic Services
John’s Septic & Excavation specializes in engineered septic system installations for residential and commercial properties throughout Southeastern Pennsylvania and South Jersey. We install systems built to meet code, perform reliably, and support the long-term needs of homeowners, builders, developers, and commercial facilities.
Systems We Install
Eljen Geotextile Sand Filter Systems
Eljen systems use a geotextile-sand filter design to treat wastewater in a compact footprint. They’re great for challenging sites, tighter lots, and areas where soil conditions limit a traditional drainfield.
Ecoflo® / Eco Flow Filter Systems
Ecoflo systems combine a filter media with controlled distribution to provide advanced treatment in a small area. Ideal for environmentally sensitive locations and properties that need higher-level treatment performance.
Jet Wastewater Treatment Systems
Jet wastewater systems are aerobic treatment units that use oxygen to break down solids more efficiently than a standard septic tank. They’re a strong option for high–use properties and projects that require cleaner effluent.
Norweco Treatment Systems
Norweco systems are engineered aerobic treatment units with multiple stages of treatment. They’re often used where strict discharge standards apply or where a conventional septic system will not be approved.
At-Grade Bed Systems
At-grade systems create an elevated absorption area directly on the natural soil surface using a layer of clean aggregate (stone) placed over prepared native soil. These are engineered systems used when soil is shallow but still capable of treatment.
Sand Mound Systems
Sand mounds are raised systems built above the natural ground using imported sand and stone. They’re designed for sites with shallow bedrock, high groundwater, or poor soil conditions, while still providing reliable on-lot wastewater treatment.
Conventional Septic Systems
A conventional septic system is the traditional method for treating household wastewater. It relies entirely on natural slope to move liquid effluent from the septic tank, through a distribution box, and evenly into a series of perforated pipes buried in gravel trenches.
