About DKNR Designs

DKNR Designs in Knoxville, Tennessee brings together demolition, septic services, and excavation under one operation, which is a practical combination for larger projects that need ground work and system installation together. Knoxville's active construction and development scene, from residential subdivisions in the suburbs to commercial projects near the University of Tennessee corridor, creates real demand for contractors who can handle site preparation alongside utility work. Rather than managing multiple subcontractors, customers working on new builds or major renovations can use DKNR for the excavation and septic components of a project. Their reach into demolition work also makes them useful for teardown and rebuild projects.

Services & Process

DKNR Designs handles septic system installation as part of a broader site development and excavation capability. New septic installations on undeveloped lots require land clearing, grading, soil testing, and precise trench excavation before a tank and drain field can be placed. Their demolition services apply to clearing old structures or removing failed septic systems before installing modern replacements. Excavation work supports all of these services, whether it's digging for a new tank, grading a site for proper drainage, or opening up access to an existing system for major repair.

Service Area

DKNR Designs operates out of Knoxville and serves customers across Knox County and the surrounding East Tennessee region.

Frequently Asked Questions

Can DKNR Designs handle both the excavation and septic installation for a new home build?
Yes, having a single contractor cover site excavation and septic installation is one of the most efficient ways to handle new construction in areas without municipal sewer. It eliminates the coordination gap between an excavation crew and a separate septic installer.
What does demolition have to do with septic system work?
Demolition is relevant when a failed septic system needs to be fully removed before a new one is installed, or when a structure sitting over an old system needs to come down first. It's also part of site clearing for new construction projects that include septic installation.
How does excavation affect the cost of a septic installation in Knox County?
Excavation is typically a significant portion of a new septic system's total cost, especially on sites with rocky soil, steep grades, or limited access for equipment. Having excavation included in-house rather than subcontracted can affect both the price and the project schedule.
Does DKNR Designs work with residential homeowners or primarily with developers?
A contractor with demolition, excavation, and septic capabilities serves both individual homeowners on large lots and developers managing multi-lot projects. Homeowners needing a new system on a challenging property often benefit from the same heavy-equipment capability that developers use.
What permits are required for septic installation on new construction in Knox County?
A septic permit from the Knox County Health Department is required before installation can begin, and a final inspection is needed before the system can be used. The permit process involves a soil evaluation and site plan review to ensure the system meets state standards.
How do I know if my land in the Knoxville area is suitable for a septic system?
A perc test, or percolation test, measures how quickly your soil absorbs water, which determines whether a conventional drain field will work or if an alternative system is needed. A contractor who does excavation and septic work can coordinate this testing as part of the site evaluation process.
