Septic System Design for Small Lakefront Lots

Many factors require homeowners to consider alternative septic systems for small lakeMorse Engineering and Construction front lots. Coping with the limitations of a small leach field on their property prompts them to seek alternative small lot septic systems to safely, effectively and affordably treat their wastewater.

Factors that Limit Leach Field Size

A few of the most common factors that can limit a property’s available leachfield space include: tight property boundaries on a small lot; required setbacks to a well, water body, or property line; large mature trees that inhibit space-clearing for a leach field; existing landscaping considerations; and inadequate soil elevation issues.

Any of these space-limiting factors will compel a homeowner to seek an alternative septic tank solution, since the smaller available leachfield space typically cannot support a traditional septic system.

For example, a small, heavily-wooded lot often contains several mature trees. For waterfront properties, the Shoreline Protection Act requires a tree survey that assigns points based on the height and circumference of each tree, and limits the number of points you can use to cut down trees. This is important for small lot space clearing, since the points-limit often determines the size of the leach field space.

Another example of a small-lot, small-leachfield footprint challenge is the 4-ft setback to the water table required by the New Hampshire Department of Environmental Services unless you use an alternative technology. For traditional septic systems – and some alternative small lot septic systems as well – this can necessitate the creation of soil-mounding to raise up the leach field.

People Often Seek Guidance on Alternative Compact Septic Systems

  • When they wish to purchase or build on a small lot with tight setbacks, their real estate agent suggests the need for an alternative septic system that allows for a small leach field.
  • When they wish to add bedrooms that will expand their home’s footprint – thus shrinking the property’s available leachfield area – so they ask their designer for a wastewater treatment system that will perform well in the new smaller-footprint leach field.
  • When they wish to add bedrooms to an existing residence, without adding to the home’s footprint.

Your property’s value – and the health of your home and family – depends on selecting an efficient, value-engineered wastewater treatment system designed for a small leach field footprint.
