Sewer Department

Sewer Department

While most Littlefield Township residents use septic systems for treatment of household wastewater, parts of the township are served by a sewer system which is managed and maintained by the Harbor Springs Area Sewage Disposal Authority (HSASDA).  The areas served are primarily located close to Crooked and Pickerel Lakes.

Sewer Back-ups:

Because a sewer is not a closed system, many things can cause back-ups and overflows.  Diapers, disposable wipes, and roots are common causes of back-ups.  Back-ups often are the result of grease build-up, and can lead to costly clean-ups and repairs as well as health concerns.  Household kitchen drains are a big source of residential fats, oil, and grease. While municipalities can adopt rules prohibiting dumping of these items into the sewer and can educate the public about the problems they cause, there is no way to absolutely prevent back-ups from happening.  Other factors can cause problems as well.

Call the HSASDA at the first sign of a problem, before the sewer back-up.  If your drains are running slowly for example, call (231) 526-6682.  Authorized sewer department personnel will come and check the HSASDA sewer main line and determine whether the problem requires a plumber.

Grinder Pumps

The following instructions were established to allow the sewer department to better to assist sanitary users on the HSASDA sewer system. Your cooperation is essential in the operation and maintenance of the grinder pumps connected to the sewer system.

To lengthen the life and operation of the grinder pump, do not dispose of the following items in the sewer:

  • Glass
  • Metal
  • Wipes
  • Seafood Shells
  • Grease/Oil from cooking
  • Aquarium Stones
  • Diapers
  • Socks
  • Rags or Cloth
  • Plastic objects like Toys and Utensils
  • Sanitary Napkins or Tampons
  • Kitty Litter.

 The following items must never be put into the sewer:

  • Explosives
  • Flammable materials
  • Lubricating oil and/or Grease
  • Strong chemicals
  • Paint thinners
  • Gasoline etc.

Individual grinder pumps and the HSASDA lift stations cannot dispose of wastewater without electrical power. If electrical power service is interrupted, please avoid water usage. Grinder pumps have a high-water level audible (buzzer) and visual (red light) alarm. If the alarm activates, the audible alarm can be acknowledged and silenced by pressing the button located on the bottom left corner of the control panel. This will silence the buzzer, but the red light will remain on. Immediately call (231) 526-6682 for an operator to troubleshoot the problem.  Avoid water usage until the problem has been corrected.

 Keep the control panel clear from obstructions including bushes and other landscaping items.

 To work properly, the grinder pump must be vented. do not cover the grinder pump with landscaping, etc.

Do Not change the grade around the grinder. The grade must allow for water to travel away from the grinder.  Refer to the Do Not and Never items above. They are the most frequent causes of bills for repairs sent to the homeowner. This list is sent as a Public Service to help you avoid damaging the grinder pump.

 Any repairs or relocation to the station, electrical service or control panel must be done by authorized sewer department personnel during regular working hours.
