Septic tanks are containers used to collect the wastewater generated from your home and store it, usually underground and connected with your drain field.

Mobile homes may have their own septic systems or can share one with other homes in a trailer park; having your own is usually best due to numerous reasons.


As you search for a mobile home, septic tank costs should also be factored in. While this will be an additional expense, over time septic systems can save money and can save on future maintenance bills. Costs vary depending on size of home and type of system installed – typically between $1,013 to $18,163.

Septic tanks collect and store waste from toilets, sinks, bathtubs and other drains in your home. It is recommended that the size of your septic tank matches up with your wastewater needs; its exact size depends on how many bedrooms there are in your residence and should always be determined with professional consultation.

Septic tanks offer an alternative to public sewer systems and can be installed by qualified technicians on your property. However, it’s important to remember that septic tanks require regular pumping and maintenance; to prevent costly problems with your septic tank in the future it should be inspected every three years and cleaned by professional septic technicians.

Septic leach fields offer another affordable alternative to septic tanks. While these systems tend to be less costly than their septic counterparts, improper maintenance could still cause environmental damage on your property. Septic fields and leach lines must remain free from obstructions; pets and children must remain away from these areas at all times.

If you’re planning on installing a septic system in your mobile home, be sure to hire a qualified technician. This will ensure the work is carried out efficiently and safely, and minimize leaks or failure. Also consider purchasing an extended warranty to protect against unexpected expenses associated with leakage or failure of the septic system.

Mobile homes sharing one septic tank are possible, provided they comply with all laws and community rules. Many municipalities will only permit one household per septic tank to use it at any given time; additionally, you must abide by local ordinances regarding proximity between houses as well as size requirements of your tank.


Before making a decision about installing their own in-house septic systems, some mobile home park owners opt to install in-house septic systems instead of connecting directly to city water and sewer lines. The advantages of doing this can include reduced utility bills as well as connecting directly with other sources of water. It’s essential that owners conduct extensive research to understand all responsibilities involved with owning their own septic system before making this choice. The first step should be choosing an ideal site for the tank – geologists or planning engineers may need to review plats of land to identify suitable locations; an engineer should review plats to locate where best-suited it should sit alongside size of mobile homes on land plots as well. Finally, hire professionals to dig and bury pipes underground before finally building mobile homes on this property.

Once your waste reaches the septic tank, it will naturally separate into its various components. Solids will settle to the bottom and become sludge while lighter materials float to the surface. Any remaining liquid waste, known as effluent, passes through a filter before entering your drainage field – this filter prevents contaminants like paper products or grease from affecting it and creating unpleasant odors.

Regular maintenance for your septic system includes cleaning out drain lines and inspecting for leaks, so be sure to schedule regular scrubbing sessions and leak checks in advance. It may be beneficial to plan out when this work should take place so as not to delay getting things done when needed.

Septic tank installation is a challenging process that involves extensive digging and plumb work. To ensure that it’s installed correctly, hiring a qualified professional is recommended, along with getting permits if applicable to prevent conflicts between neighbors.

Some may ask whether two trailers can share one septic system, but this is generally not permitted as it could cause unnecessary conflict between neighbors and may even be illegal in certain jurisdictions. Instead, it would be wiser to install separate septic tanks for each trailer; doing so can save money while decreasing environmental contamination risks.


If your mobile home includes a septic tank, local health departments require that the appropriate permits are secured to ensure its functionality. Percolation tests will help verify whether or not soil at your chosen location can absorb waste efficiently. You can learn more about requirements by reaching out to local health departments or consulting with a professional septic system inspector.

Based on the size and number of bedrooms in your mobile home, it may require a larger septic tank than those used by single-family houses. A geologist will help to select an appropriate tank size during the permit process; other considerations may also include number of inhabitants in selecting its size – often measured in cubic feet.

Septic tanks are specifically designed to separate solid waste from liquid waste, with solids falling to the bottom and liquid waste floating to the top. When liquid waste leaves the septic tank and enters the drain field or leaching field, it naturally filters through and is naturally cleansed and filtered by nature. As plants nearby can adversely impact this system and create unpleasant odors, avoid planting anything near such drainage fields unless doing so would not harm your septic system or create unpleasant odors.

Manufactured homes feature plumbing lines that extend through their belly boards, and these can connect either to public sewage lines or septic tanks. A septic tank should ideally be situated lower ground so as not to reach by plumbing lines, while being well insulated against heat loss.

Though two mobile homes technically could share one septic tank, before doing so it is wise to check your state and local laws first. Many states forbid such sharing; if allowed however, then all applicable rules regarding usage such as distance must be observed between homes and tank must also be abided by.


No matter whether or not your home has access to municipal sewer, waste disposal systems will still be essential. While septic tank/absorption field systems offer potential savings over the long haul, it is still wise to conduct adequate research prior to making a purchase decision in order to get the best value for your money and comply with local regulations.

Mobile home septic systems must be located at least 10 feet away from their respective mobile homes and buried two to four feet deep, in an area at least as wide as their mobile home itself. Furthermore, septic tanks should be situated close to drain lines for easy maintenance purposes.

Choose a tank manufactured by a reliable brand to prevent leaks and corrosion over time, such as leaks. Look for one with warranty coverage, upholds high safety standards, and has an outstanding consumer rating. Additionally, always consult the local building authorities as to which septic system may be allowed in your neighborhood.

Before installing a mobile home septic system, obtaining a permit from your local public health department will be necessary. This process includes performing a percolation test on the soil to assess suitability for sewage disposal. Tank size will depend on how many bedrooms or residents reside within your home and should always be discussed with installer before making final decisions.

Once you’ve obtained a permit, the installation process can begin. A septic tank for mobile homes can be installed either on concrete or gravel beds – although gravel beds tend to be easier for installing and maintenance purposes; concrete tanks tend to last longer.

Once your septic tank has been installed, the next step will be connecting it to your mobile home plumbing. Wastewater from your home will flow directly into the septic tank via an absorption field using PVC pipes – for optimal performance use these materials for this installation process.
