Our Services


Any and all needs for moving dirt on residential or small commercial lots. Fanning Excavating also delivers and places black dirt, fill, and road rock.

Septic Systems

Also known as POWTS(private onsite wastewater treatment systems), Fanning Excavating has been installing POWTS for over 70 years. No site is too difficult. No installation is too tough. Between the 3 generations, there have been thousands of POWTS installed over the years.

Site Utilities

For commercial sites and residential sites, Fanning Excavating installs sanitary sewer laterals, domestic water laterals, fire protection laterals, and all facets of stormwater management.

Septic Maintenance

Fanning Excavating performs all maintenance work for the POWTS. This includes routine and emergency pumping services of septic tanks and holding tanks, pump and float replacement in dose tanks, any and all pipe repairs ranging from sewer laterals to force main leaks, some minor electrical repairs at the dose tanks, or electrical boxes. We also troubleshoot any POWTS that may be having issues. Fanning cannot stress enough that the best time to do troubleshooting is immediately when a problem seems to arise. Waiting for a problem to fix itself is never a good idea.

POWTS Design

Fanning Excavating has its own in-house designer with over 40 years of experience. From the site and soil evaluation to the design of the POWTS, no site is too difficult to match with the correct POWTS.

POWTS Evaluations

Fanning Excavating does POWTS evaluations for home sales. This is a comprehensive evaluation that leaves no stone unturned. Whether you are selling or purchasing, let Fanning give you a clear picture of what condition the existing POWTS is in.
