Septic Services near you

EPA describes the visit plainly: when you call a septic service provider, he or she will inspect for leaks and examine the scum and sludge layers in your septic tank. That examination is the whole point of the appointment, because it converts a guess about timing into a measurement. Your tank has a T-shaped outlet that prevents sludge and scum from leaving the tank and travelling into the drainfield area, and the layers are measured against it.

There are three thresholds worth knowing, all of them EPA's. The tank should be pumped if the bottom of the scum layer is within six inches of the bottom of the outlet, if the top of the sludge layer is within 12 inches of the outlet, or if more than 25 percent of the liquid depth is sludge and scum. EPA also advises writing down the sludge and scum levels found by the septic professional, which over two or three visits turns into a pumping interval fitted to your household rather than a rule of thumb.

A full inspection goes wider than the tank. EPA's description of a typical inspection includes a review of the system permit, design and installation records, including the system age, a review of the septic tank pumping and system maintenance records, and assessing the condition of the septic tank effluent filter where one is installed. Ask for those records to come back to you in writing, because in many states a septic system must be inspected when real estate changes hands, and the file you have built is what that inspection starts from.

EPA is direct about the causes: most septic systems malfunction because of inappropriate design or poor maintenance. Some soil-based systems were installed at sites with inadequate or inappropriate soils, excessive slopes or high ground water tables, and those conditions can cause hydraulic failures and contamination of nearby water sources. A system in that category was compromised before anyone moved in, and no amount of careful use fully compensates for it.

The maintenance half of the problem is mechanical and slow. Failure to perform routine maintenance lets solids in the tank migrate into the drain field and clog the system, which is exactly the outcome the pumping thresholds exist to prevent. EPA explains the mechanism behind heavy solids loading too: if a large amount of water enters the tank or the tank fills with solids, solids can be pushed into the drainfield, clogging the pipes and thickening the biomat, the bacteria layer that forms on the bottom and sides of the drainfield trenches.

That distinction matters when you are reading a quote. Pumping and filter cleaning restore the tank; they do not restore a drainfield whose soil has already been sealed by years of solids, and they do not move a system that was sited in the wrong soil. A contractor who explains which of those you are dealing with, and shows you the sludge and scum measurements behind the explanation, is giving you something you can act on.

Treat it as contamination rather than mess. EPA's guidance is that if sewage from your plumbing fixtures or onsite system backs up into your home, you should avoid contact with the sewage as it may contain harmful pathogens, and contact your local health department or regulatory agency for guidance. Surfacing untreated wastewater from a failed drainfield is described by EPA as a direct public health hazard to anyone exposed to it, with children and pets able to be exposed without knowing, so rope off a wet patch in the yard before you do anything else.

For cleanup, EPA says personnel should wear protective clothing such as long rubber gloves and face splash shields. After cleanup is complete, thoroughly wash all equipment, tools and clothing used during cleaning as well as the flooded area, and disinfect all items or areas exposed with a mixture of 90 percent water and 10 percent household bleach. EPA adds that the area should be dried out thoroughly and not used until it has been completely dry for at least 24 hours.

Stop adding water to a system that cannot take it. Every flush, shower and load of laundry goes to the same place, so the fastest way to keep a backup from getting worse is to pause household water use until a septic professional has seen it. EPA's short list of who to call is a local septic system service provider, your local health department, or the onsite wastewater treatment regulatory agency for your area.

This is the part most often described wrongly, so it is worth stating precisely. EPA does not regulate single family home septic systems. Individual onsite systems are regulated by states, tribes and local governments, not the federal government, and in most states local health departments issue construction and operating permits to install septic systems under state laws that govern public health protection and abatement of public nuisances. EPA notes that some states add water resource protection provisions because of the possible impacts from nitrogen and phosphorus.

That structure has a practical consequence: the ongoing oversight you might assume exists usually does not. EPA observes that very few permitting agencies conduct regular inspections of septic systems after they are installed. The schedule is yours to keep, and the records are yours to hold.

Start by getting the file. EPA advises that a septic system is typically permitted and inspected by your local permitting authority, meaning the local health or environmental department, and that you can contact them to obtain a copy of your property's septic record drawing, the as-built design, and copies of the permits, which may also carry the installation date and the soil properties. The same office keeps lists of local septic professionals, and EPA notes that many states will license or certify septic system installers, so that is where a licence claim gets checked rather than taken on trust.
