615 Septic Tank Pumping is a septic tank pumping company serving Nashville and Davidson County, Tennessee. It pumps, cleans and inspects residential and commercial septic systems, services grease traps and interceptors, and diagnoses drain fields that have stopped accepting.
What we actually do on a visit
Both tank lids are located and opened — hand-dug where they are buried, which on wooded and large-lot Davidson County properties is most of the time. Sludge and scum depths are measured against the tank's capacity before anything is pumped, because that measurement is what tells you whether your interval is right. The tank is then pumped completely: liquid, floating scum and settled sludge, followed by a backflush. A liquid-only draw-down leaves behind exactly the material that threatens your drain field, and makes a tank look serviced while the problem stays where it was.
With the tank empty, the inlet baffle, the outlet baffle and the effluent filter are inspected — the three components that fail quietly and take a drain field with them. You get told what was found, not just that the tank was emptied.
The standards this work follows
Septic tank pumping contractors in Tennessee are governed by Tenn. Comp. R. & Regs. 0400-48-01-.20. Subsurface sewage disposal systems fall under TDEC's Subsurface Sewage Disposal Program, and Davidson County administers its own septic program as a TDEC contract county, with Metro Public Health's Environmental Engineering Services handling soils interpretation, system design, percolation-test monitoring and groundwater protection.
Grease work follows Metro Water Services' FOG program: traps serviced at least every 30 days, interceptors at least every 90, service whenever fats, oils, grease and settled solids reach 25% of the unit's capacity, certified hauler manifests, and three-year record retention.
Where we work, and why it is that shape
Nashville and Davidson County. Septic in this county is concentrated in the areas the postwar sewer extension never reached — a project that began soon after the 1963 consolidation and ran into the early 1990s — plus the large-lot areas shaped by the county's 1946 decision to require half-acre minimum lots, and larger where soils were poor, expressly to give drain fields room.
We cover Davidson County. Where an area has a dedicated service-area page, it is because there is something specific worth knowing about septic there — the age of the systems, the soil, the water table, or the rules that apply. Areas without their own page are still served.
How we price it
Ranges are published on this site and there is a cost estimator that gives you a number from three questions without an email address or a phone call. You get a band before we come out and a firm figure before we do anything that changes it. If the tank is opened and something needs doing that was not in the quote — compacted sludge, a corroded baffle, a split effluent filter — you are told what it costs and you decide.
What you will not find on this site
There are no reviews, star ratings, testimonials or customer counts here, and no claims about years in business or jobs completed. That is deliberate. This is a new operation, none of those things exist yet, and inventing them would be both dishonest and, under the FTC's rules on fabricated reviews, unlawful.
What stands in their place is everything that is true on day one: published pricing, the actual regulations the work follows, the specific local geology and history that shape septic in this county, a calculator that answers your first question without a sales call, and a straight comparison of what a cheap pump-out leaves behind. When real reviews exist, they will appear here — and not one word before.
If you have used us and are willing to say so, the review page explains how.
