Failing Septic Leach Field Atlanta
Atlanta Metro Area and Athens
SEPTIC FIELD FAILURE CAUSES
- Septic Field System Age: eventually even a well-maintained Septic System will eventually clog and have to be replaced.
- Septic Tank Pumping schedule: don’t forget to pump out the septic tank regularly every 3 to 5 years (solids/grease are discharged into the fields, clogging the soil).
- Soil clogging at the biomat layer which forms below and around the drainfield trenches
- Septic Tank Baffle failures: corrosion and rust-off of steel septic tank baffles is a significant cause of disposal field failure in systems that have otherwise been maintained.
- Blocking or sealing the ground surface over a septic system will be a problem over just about any septic effluent field. Don’t build anything (compacts the soil).
- no building
- no fish pond
- no patio
- no tennis court
- no parking area
- no playground
- no above ground swimming pool
- no concrete blocks
- no building or deck
- Driving vehicles or any heavy equipment over the septic system, leach field, drainfield. Heavy traffic over the system can compress soil or break pipes, rendering the system inoperative and requiring costly repairs.
- Septic tank or field construction mistakes: Improper original construction by bad site selection , especially on rocky, poorly-drained sites (pipes settle, for example) including improper trench grading & routing or extending piping over variations in trench grading without proper bedding (causing pipe settlement).
- Shortcuts by the drainfield constructing such as
- Failure to install drainfield trenches of depth, length, width, slope specified by the septic system designer & planner
- Improper septic field location: one way to have a quick failure of a drain field is to install it in an area of high seasonal water tables
- Surface & subsurface runoff water control mistakes: Ignoring site runoff and groundwater levels: Improper absorption field siting is found at some properties where the builder fails to consider site runoff or natural groundwater paths.
- Steep slope septic systems: Placing a conventional septic system drainfield on a steep slope
- Sloppy pipe layout and connections is a common cause of early failure in new drainfields
- Placing structures, patios, or paving over the absorption system:such as by installation of paving, a patio, or weed-blocking solid plastic
- Placing improper substances into the building drains and septic system. Don’t use the septic system to dispose of illegal oils, chemicals, fats, greases
- Discharging excessive salts or other chemicals which destroy the the biomat formation, clogging the soil. This problem and measures to protect and extend the life of the biomat
- Planting trees, deep rooting shrubs, and certain ground covers on the septic absorption field (roots enter pipes) and evaporation can be blocked.
- Use of septic tank or drain field additives which claim to extend system life can generate so much activity in the tank that solids are held in suspension and forced into the soil absorption system! Do not add any treatments, chemicals, yeast, or other treats to a septic system. In general these treatments don’t work
- Wet weather installations of septic systems & fields: Installing a drainfield in wet weather (which compacts the soil) is likely to mean a shorter field life.
