Problem: Waste water from an on-site sewage system backs up into home sewer lines or seeps to the ground surface.
Common problems in private sewer systems are undersized drain fields, undersized septic tanks, and poorly maintained septic tanks (which cause clogged dry-wells or drain fields). Adequate drain field size depends on soil type and amount of sewage treated.
If the ground above the drain field is especially wet or soggy, or if the capacity of the tank is too small, the system may be inadequate. A 1,000-gallon septic tank is considered a minimum for 3-bedroom homes; 1,250 gallons for 4-bedroom homes, and 1,500 gallons for 5-bedroom homes.
What to do:
All septic tanks periodically need to have sludge and scum solids removed, depending on their tank size and the daily load dis¬charged into them. Some tanks need to be pumped out every 2 years, but others may need it only once every 10 years. [Read more...]
