New Septic Systems for Kensington Properties
A new septic system is a long-term investment. Getting it right means a proper site evaluation, a design that fits your property and a permit approved before any digging starts.
Septic companies that work across Montgomery County can guide you through each step and handle much of the paperwork.
From soil test to finished system
A septic installation starts with a soil and site evaluation, which decides what kind of system the lot can support. A designer then sizes the system for the number of bedrooms, the plan goes to the Montgomery County health department for a permit, and the installer digs, sets the tank and builds the drain field before a final inspection.
Septic system types and when they fit
A conventional gravity system works where soil drains well and there is room for a field. Where soil is shallow, wet or slow, designers turn to pressure distribution, mound systems, chamber systems, drip dispersal or aerobic treatment units. The soil test, not preference, usually decides which one a lot needs.
Working with local regulators
Septic rules exist to protect groundwater and neighbors' wells. Before installation, plans are reviewed for setbacks from wells, property lines and water. Inspectors typically check the work before it is covered. Ask your installer what approvals are needed in Kensington and how long review usually takes.
What affects installation cost
The biggest factors are system type, soil conditions, lot access, tank size and local permit requirements. Conventional systems in good soil generally cost the least. Mounds, aerobic units and other engineered systems cost more to build and maintain. Removing an old system and restoring landscaping add to replacement projects.
Protecting your investment
A new system can last decades with basic care. Know where every part is, avoid planting trees near the field, send roof water away from it, and keep grease, wipes and chemicals out of the drains. Schedule the first inspection and pumping so you have a baseline for later visits.
Choosing an installation company
Look for experience with the soils and systems common around Kensington and Chevy Chase, Chevy Chase Village, Somerset, clear written quotes and a plan for permits and inspections. A good installer explains tradeoffs between system types rather than pushing one option.
Scheduling a septic installation
Start early if you are building or replacing a failing system. Book the soil evaluation first, since everything else depends on it. Ask your installer how long permits are currently taking with the Montgomery County health department, and plan for weather, especially if the work falls in winter or a rainy season.
What experienced installers watch for
Good installers in Kensington pay attention to setbacks from wells and property lines, the slope of the lot, and where roof and yard water drains. They also plan how equipment will reach the site without compacting the future drain field. They also confirm the design matches the permit before the first shovel goes in. Small details at this stage decide whether the system lasts decades or needs early repair.

Septic Installation questions in Kensington
- Can I install a septic system myself?
- Most areas require licensed designers or installers and inspections. Check with the Montgomery County health department before planning any work yourself.
- What is a mound system?
- A mound system raises the drain field above the natural soil using sand and fill. It is used where the soil is too shallow, too wet or too slow draining for a conventional field.
- Can a replacement system go in the same place?
- Sometimes. It depends on the condition of the soil in the old field and local rules. Many replacements use a new area of the yard.
- Is SepticTank.com the installer?
- No. SepticTank.com connects you with an independent local septic company that serves Kensington. That company designs, installs and prices the system.
