Is Septic Tank Maintenance Different at a Lake House?

At a lake house, more is at stake. Maintaining water quality is the primary concern with any water-adjacent sanitary sewage system. Lake homeowners have a responsibility to the nearby body of water.

Despite the higher call of duty, there should be no difference in your behavior at a residential home versus a lake home. For instance, in both houses, you would not pour chemicals down the drain, use the garbage disposal, or park near the septic tank. The biggest difference would be how often you perform maintenance on it since you’ll want to clean and empty lake home septic tanks more regularly.

Even then, there isn’t a one-size-fits-all approach for septic tank maintenance at a lake home. The type and cost of maintenance depend on the topography, presence of bedrock, the height of the water table, and type of soil.

There are multiple considerations when deciding on the type of system and its maintenance. Septic systems are often necessary for the lake homeowner due to the often rural locations of many lakes. Consult a local septic tank expert for personalized advice on the topic and remember to consider the septic system when buying, selling, or building your next lake home.

Septic System Design Basics

Site Evaluation: There are two considerations to "perc test" or site evaluation:

  1. the soil type and
  2. projected sewage usage.

To determine your projected sewer usage, please check with your local health department or regulator agency. Please note: the site evaluation is done with a backhoe.

Soil Classification:

Soil classification is determined by the US Department of Agriculture Soil Conservation Classification System. The importance of soil classification should not be underestimated. If the soil is inaccurately classified, it could cause unnecessary delays and expense. Please consult with a soil expert before proceeding with your septic system design project.

Designing a Septic System:

Hire a septic system design engineer to design a septic system based on your house or building's plan; this will help to ensure that the septic system design meets all local regulations.

Department of Health Evaluation:

In most states, the Department of Health is the agency that regulates septic systems. This agency also reviews and approves and/or denies septic system design plans. The engineer that designed your septic system will have to not only submit the designs, but also the soil classification results and the "perc test" or site evaluation in order for the plans to be considered for approval.


Congratulations! Your septic system design has been approved. If you followed the proper septic system design procedures, you should hear those words. If approved, the septic system engineer should give you a copy of the approved designs.

Now you have a basic understanding of the process for designing a septic system. For more information, contact Morse Engineering and Construction.


Adding a Septic Tank and Connecting to Existing Sewer Lines

The simplest way to add to your septic tank while remaining connected to existing sewer lines is to simply add an additional septic tank. This gives your home a larger wastewater capacity, and gives your septic system more time to treat the wastewater before draining.

If you're adding a septic tank, first the correct placement needs to be determined, it should be between your current tank and your drain field (sometimes called a septic field line).

The ground for your new septic tank must be excavated using the dimensions of your septic tank as a guide. An excavator will be used to make an adequately sized hole, taking special care around the outlet of the older septic tank.

A 4-inch pipe will be used to connect the two septic tanks. The pipe will be placed into the inlet hole of your new septic tank before it is lowered into the ground. After your new septic tank has been lowered, the other end of the pipe will be inserted into your old septic tank's outlet hole. The pipe should hang over the two tank interiors by around 2 inches.

The hole around your new septic tank is then refilled with soil. The compactness of your soil will be checked using a vibrancy soil compactor.
