CESSPOOL, SEPTIC TANK OR WWTP: HOW TO CHOOSE THE RIGHT WASTEWATER SOLUTION FOR A MOBILE HOME?

Do you not have the option to connect your mobile home to the public sewer system? Don’t worry – there are several ecological and reliable ways to handle wastewater from a mobile home. In this article, we explain the differences between a cesspool, a septic tank, and a domestic wastewater treatment plant (WWTP), and help you choose the most suitable solution.

Preparation of Super Arktik ® mobile homes for utility connections

All Super Arktik ® mobile homes are handed over to customers with complete inspections of utility systems, including:

  • Electrical, water, and wastewater system inspections
  • Pressure testing of the internal wastewater piping

This ensures that your mobile home is technically ready for immediate connection to the selected system – whether a cesspool, septic tank, or domestic wastewater treatment plant (WWTP).

Wastewater solutions for mobile homes without sewer connection

If you plan to place your mobile home on a plot without access to a public sewer system, you have several proven options for wastewater management. Each solution has its own advantages and disadvantages, which we explain below.

. . . . . .

1. CESSPOOL – A simple solution without the need for electricity

Cesspool is a watertight tank without an outlet, used to collect household wastewater. This system is very simple but requires regular maintenance.

When is a cesspool suitable?

  • Recreational or occasionally used mobile homes where no other solution is available.

Key characteristics:

  • Does not treat wastewater – contents must be regularly pumped out
  • Requires regular monitoring of the fill level
  • Emptying must be carried out by a certified company
  • Waste disposal records are required (may be checked by authorities)

Advantages:

  • Low initial cost
  • Simple and quick installation

Disadvantages:

  • Frequent pumping required with smaller capacity
  • Possible odor issues
  • Legal obligation to document waste disposal

2. SEPTIC TANK – A more ecological solution with pre-treatment

Septic tank is a tank where mechanical pre-treatment of wastewater takes place. The pre-treated water is then absorbed into the soil or further treated in a biological filter.

When is a septic tank suitable?

  • Permanently occupied mobile homes without sewer access, provided the land has suitable soil conditions for infiltration.

Key characteristics:

  • Most commonly a three-chamber system – sludge settles, fats float, remaining water flows out
  • Must be combined with an infiltration field or soil filter
  • Does not require electricity, but treatment efficiency is lower than WWTP

Advantages:

  • Low energy requirements
  • Less frequent pumping compared to cesspools

Disadvantages:

  • Limited treatment efficiency
  • Not suitable for areas with impermeable soil

3. WWTP – Domestic wastewater treatment plant for permanent living

Domestic wastewater treatment plant (WWTP) mechanically and biologically treats wastewater, often to a level suitable for infiltration, discharge into a stream, or reuse (e.g. for irrigation).

When is a WWTP suitable?

  • Permanently occupied mobile homes without sewer access where the owner seeks a long-term, ecological solution.

Key characteristics:

  • Requires electricity (aeration, pumps)
  • Requires regular maintenance and servicing
  • Treated water can be discharged directly into nature

Advantages:

  • High treatment efficiency (up to 95%)
  • Possibility of water reuse
  • Lower operating costs compared to a cesspool

Disadvantages:

  • Higher initial investment
  • Requires electricity and regular servicing

Conclusion: Which system is best for you?

The choice between a cesspool, septic tank, and WWTP depends on your specific needs and the conditions of your plot. For recreational mobile homes, a cesspool may be the simplest solution. For permanently occupied homes with suitable soil conditions, a septic tank is a better option. If you are looking for a long-term and ecological solution, a WWTP is the most efficient choice.

All Super Arktik® mobile homes are factory-prepared for connection to these systems – including complete inspections and wastewater pressure testing – allowing you to move in immediately without worries.
