Residential Septic Systems

  • Virtually every home is either connected to a municipal sanitary sewer system or has an on site sewer system, also known as a “Septic System”.
  • Septic systems have various designs and vary from location to location depending on individual site and volume requirements.
  • By far the most common is a system that transfers water and waste from the house via pipes to a septic tank.
  • Septic tanks are typically located underground and are usually close to the house.
  • They can be made of concrete, metal or HDPE (plastic)
  • The waste inside the septic tank is broken down by bacteria.
  • Gasses are produced which are generally vented via the plumbing system.
  • Remaining solids either sink to the bottom of the tank (called sludge) or float to the top (called scum).
  • These solids are further broken down by bacteria over time however not all the solids can be broken down completely.
  • Over time the remaining solids accumulate and must be pumped out of the system.
  • Septic tanks are designed to allow the solids to float to the bottom and the scum to sit on the surface through the use of baffles inside the tank.
  • The cleaner effluent is then able to escape the system through piping to a distribution box which breaks out into several pipe runs leading this effluent to be distributed throughout the drain field and absorbed into the earth.

Commercial Septic Systems

  • Sizing for septic systems and drain fields is more difficult than residential installations.
  • Commercial septic systems vary widely in the wastewater volume per person per day depending on the type of facility, number of visitors to it, how long they stay there and what activities they pursue
  • Various factors are involved in the design of a commercial (or residential) septic system such as:
    • Soil percolation rate
    • Number of building occupants (or number of bedrooms in a residential property) and/or the assumed design level per day.
    • The number of meters of drainfield required to handle the daily flow volume of the design
  • Commercials systems require more complex analysis and contingencies that are not required in a residential installation
  • Hospitals, airports, schools, rest homes, restaurants, hotels, apartment buildings etc.

Septic System Inspections

  • Our professionally trained septic system inspectors work with realtors, home inspection companies, mortgage companies and home owners to provide a thorough inspection
  • A comprehensive inspection includes:
    • Collection and review of available sewage system information
