Septic Services in South Jersey

Our professional septic services include:

Septic System Installation

Planning and Permits

  • Soil testing: a certified professional performs a perc test or soil boring analysis to check drainage speed and water table depth

  • Permitting: site plans and system designs based on your home’s bedroom count will be submitted to your local health department or municipal board prior to breaking ground

  • Layout: utility lines will be marked so that we can stake out the exact placement for the tank, distribution box, and lateral leach lines

Tank and Field Installation

  • Excavation: LaSassa Plumbing crews will dig holes and trenches using heavy machinery, keeping a proper downward slope from the house to the tank

  • Tank Placement: a pre-cast concrete or heavy-duty polyethylene tank will be set on a stabilized gravel or sand base before inlet and outlet PVC pipes are connected with sanitary baffles

  • Drain Field Setup: we will install gravel and perforated pipes (or interlocking plastic leaching chambers) level in the trenches so that wastewater can uniformly filter into the soil

  • Backfilling: we will carefully fill and compact soil around the system components to prevent shifting or surface settling

Septic System Repair

Common septic system repair issues range from simple breakages inside the tank to total drain field failures. Promptly identification of warning signs—like slow drains, odors, or soggy spots—can prevent the need for total system replacement. If you suspect that you might have a septic problem, call LaSassa Plumbing right away!

Our septic system repair services include common issues such as:

Frequent Mechanical and Structural Problems

  • Broken baffles: inlet or outlet baffles break or corrode, allowing solids to escape and clog the drain field

  • Failed pumps or floats: electrical pumps or mechanical floats in mound or pressure systems stop working, causing high water levels

  • Collapsed distribution boxes: concrete or plastic D-boxes crack or shift under weight, unevenly distributing wastewater

  • Cracked lids or risers: damaged access ports let in surface water and dirt, overloading the tank volume

Drain Field and Piping Complications

  • Biomat overload: thick, sticky organic layers build up in the trenches and block soil absorption

  • Tree root intrusion: roots crack pipes or block flow lines

  • Soil oversaturation: heavy water use or poor surface drainage keeps the leach field permanently waterlogged

  • Crushed or sagging pipes: heavy vehicles driving over the line can bend or break underground lines
