Key Points: Septic System (Pozo Séptico) Maintenance Lifestyle Tips & Routine

Safety First (Maintenance Mindset)

  • Do maintenance with safety in mind
    • Keep children away from the septic area—it’s dangerous due to gases.
    • After unclogging/opening the system, plan for gas release time:
      • Leave the system open/cleared for 20–30 minutes so gases can vent.
    • Create a temporary safety enclosure/fence (e.g., sticks + rope) to prevent curious people from wandering in.

Tools and Protective Gear

  • Wear gloves, mask, goggles, and boots.
  • Have the right tools ready for handling/cleaning:
    • Buckets, ladle, hoe, pick/shovel
    • A measuring rod
  • Use a 2-meter pole/long rod (as shown in the referenced video) covered for safe handling/movement.

Step-by-Step Workflow Before Draining/Handling Sludge

  1. Clear/unclog the tank first.
  2. Wait 20–30 minutes for gases to dissipate.
  3. Measure sludge height with the rod:
    • Insert the rod straight down to the bottom of the first chamber (where discharge arrives).
    • Keep it in place for about 5 minutes, then remove slowly.
  4. Decision rule based on measurement
    • If sludge height is < 30 cm: cover and leave.
    • If sludge height is > 30 cm (example shown: 40 cm):
      • Remove sludge so that 10 cm remains (example: remove 30 cm and leave 10 cm).
      • Reason: leaving ~10 cm helps keep bacteria active for ongoing breakdown.

How to Remove Sludge/Scum Safely

  • Make a disposal hole:
    • 80 × 80 cm
    • Depth: 1 meter
  • Deposit removed sludge/scum/grease in the hole.
  • Keep disposal far from neighbors and streams to reduce environmental contamination.
  • After removal:
    • Cover with soil
    • Add lime (lime is used as part of treatment/management)
  • Remove scum/grease, but do not remove all sludge—maintain the 10 cm layer.

What NOT to Put in the Toilet/Bathroom

These actions help prevent bacteria death and clogs.

  • Don’t flush:
    • condoms
    • sanitary napkins
    • toothbrushes
    • toilet paper (implied as problematic)
  • Avoid dumping into plumbing that reaches the tank:
    • oils
    • flammable liquids
    • paints
    • bleach
  • Don’t wash internal “filters/popcorn” with detergent
    • Detergent kills bacteria.

Housekeeping / Trash Separation Tip

  • Use two bins to separate organic vs. inorganic trash at home (claimed to work well and reduce septic problems).

Filter/Biodigester “Popcorn” Maintenance

  • The video explains that the chambers house biodigester bacteria.
  • These are colloquially called “popcorn” (filters/straps with similar function in some systems).
  • Cleaning method shown:
    • Clean using pressurized water
    • Without detergent
  • In some setups, the “popcorn” may be replaced by similar strap/filter structures.

Flat Areas: Drainage Requires Pumping

  • If the septic tank is in a flat area, drainage must be done using a pumping system (not gravity).

Recordkeeping (Maintenance Log)

Fill out a form documenting:

  • Inspection date (today)
  • Sludge height (cm)
  • Next maintenance due date

Suggested frequency mentioned:

  • Every 6 months for a house
  • Every 3 months for public places (schools, community centers, and other public facilities)

Also note in observations:

  • Where the well/hole was made
  • Where the sludge was deposited
  • That lime was added
  • A reference point for locating the well/mark (so the next person knows where to work)

Notable Locations / Products / Entities Mentioned

  • “Popcorn”: the colloquial term for the septic tank’s biodigester bacteria filter/media (or strap-like replacements).
  • EPM (Empresa de Servicios Públicos de Medellín) and the Mayor’s Office of Medellín: referenced in the closing message about domestic wastewater management.
