Home Sewage Treatment Systems (HSTS)
Questions to ask about
installing a HSTS
- Is the water table and bedrock
sufficiently deep to allow for installation of tank and proper infiltration from the leach field?
- Does the permeability of the soil
promote good infiltration of septic effluent?
- Is any public sewer service planned for
- Does the lot meet minimum Health
Department requirements, including isolation distance between the leach
field and the well?
- Is the lot located in a flood hazard
- Is the lot large enough to permit
relocation of the leach field if needed in the future?
For an existing HSTS
- Is there a
detailed map showing the location of the septic tank and leach fields? You
should keep a file with records of the installation and
maintenance of existing septic systems.
- Does the property have access to an
adequate outlet for curtain drain discharge?
(a curtain drain is a subsurface drainage tile around the leach field for
draining excess water away so that normal infiltration can continue).
Maintenance and potential problems
- Septic tanks need to have the solids
removed from the bottom at a certain frequency, depending on the
size of the tank and number of people living in the house.
Check your phone book for listings of businesses that pump septic
systems. This information should be included in your file.
- Poor soil drainage in your leach
field and/or inadequate tank maintenance can cause sewage to back up
into your house. Most soils in Ohio are not suitable for
septic leach fields. However most systems were installed on
inadequate soils because zoning regulations generally have not been
stringent enough to protect water quality. As a result,
inadequately treated sewage from HST systems continues state-wide to
degrade water quality. See details on HSTS at the Ohio Department of Health site.
