The bacteria in your tank can't break down everything. Materials like soap residue, hair, and coffee grounds accumulate. When the scum and sludge layers grow too thick, they can block the outlet pipe, forcing solids into the drainfield and compromising its filtration ability. A regular septic tank pump out removes these layers, preventing clogs, protecting the expensive drainfield, extending system life, and avoiding hazardous sewage backups.
It's important to know which system you have. A septic tank treats wastewater and has an outlet to a drainfield, requiring pumping every 3-5 years. A holding tank simply stores all wastewater with no outlet or treatment, requiring pumping every 2-4 weeks. This difference in function leads to a significant difference in long-term maintenance costs.
Lifespan depends on material and maintenance. With proper care, a tank can reach or exceed its expected lifespan.
Concrete tanks are durable and can last 40 years or more.
Steel tanks have a shorter lifespan of 15-20 years due to corrosion.
Plastic tanks are corrosion-resistant and can last for decades, similar to concrete.
Consistent maintenance is the key. Following simple ways to extend your septic system life, like regular pumping, is the best way to protect your investment.
Ignoring these warning signs can lead to costly repairs. Look out for:
Slow drains: When multiple fixtures throughout your home drain sluggishly, your tank is likely nearing capacity.
Gurgling sounds: Strange noises from your plumbing can indicate trapped air in an overloaded system.
Sewage odors: Unpleasant smells from drains or in your yard are a clear red flag.
Pooling water: Soggy areas around your drainfield, even in dry weather, mean the ground can no longer absorb wastewater effectively.
Lush grass: Unusually green grass over the drainfield indicates it's oversaturated with nutrient-rich wastewater.
Toilet flushing problems: Incomplete flushes or needing multiple attempts to clear the bowl are common signs.
Sewage backup: If wastewater appears in toilets or tubs, you have an emergency.
The general rule for most homes is to pump the septic tank every three to five years. This timing strikes a balance between preventing problems and avoiding unnecessary costs.
However, alternative systems with electrical components or pumps require annual inspections to ensure all parts are working correctly.
Your ideal pumping schedule depends on several factors:
Household size: More people means more wastewater and a need for more frequent pumping.
Tank size: Larger tanks have more capacity and can go longer between pump-outs.
Water usage: High water usage (long showers, frequent laundry) fills the tank faster.
Garbage disposal use: Food waste adds significant solids, often requiring pumping every 2-3 years.
High-efficiency appliances: These reduce water usage, which can help extend the time between pump-outs.
First, we need to find your tank. If you have as-built drawings of your home, they can show us where to look. If not, our technicians can probe the ground or follow the main sewer line from your house. The easiest access is provided by risers, which are plastic or concrete cylinders that extend the tank's access port to ground level. Risers eliminate the need for digging, making every future septic tank cleaning faster and protecting your landscaping.
Once the tank is uncovered, we get to work. Most tanks have two compartments, and we uncover the lids to both to ensure a complete job. We use a powerful vacuum hose from our truck to remove all the accumulated scum and sludge from both compartments.
While pumping, we also conduct a visual inspection of the tank's interior, checking the inlet and outlet baffles and looking for any cracks or damage. A typical pump out takes 20-60 minutes, depending on tank size.
While DIY projects can be satisfying, pumping a septic tank is a job best left to professionals. The risks are significant:
Specialized Equipment: The job requires industrial-strength vacuum trucks designed to handle raw sewage.
Health Hazards: Septic tanks produce toxic gases (methane, hydrogen sulfide) that can be deadly.
Waste Disposal Regulations: Septic waste must be transported and disposed of at approved facilities according to strict environmental laws.
Incomplete Job: Without proper expertise, you risk leaving solids behind or damaging tank components.
Your septic tank is a biological system, not a trash can. Only human waste and toilet paper should go down the toilet. Avoid these items to protect the helpful bacteria in your tank:
Grease and Oil: These solidify and create thick scum layers that clog your system.
"Flushable" Wipes & Feminine Hygiene Products: These do not break down like toilet paper and are a primary cause of clogs.
Harsh Chemicals: Bleach, drain cleaners, and paint can kill the beneficial bacteria your system needs to function.
Food Waste & Coffee Grounds: These add excessive solids that accumulate quickly. Heavy garbage disposal use means you'll need to pump your tank more often.
Other Items: Never flush cat litter, medications, dental floss, cigarette butts, or paper towels.
Your drainfield is the most expensive part of your system to replace, so protecting it is critical.
Never drive or park on the drainfield. The weight compacts soil and can crush pipes.
Avoid construction like patios or sheds over the area. Tree roots can also invade and damage pipes.
Plant only grass or shallow-rooted plants over the drainfield.
Divert rainwater from gutters and sump pumps away from the area to prevent oversaturation.
Conserve water to reduce the load on your entire system.
The cost of a pump out is an investment in preventing much larger expenses. The final price is influenced by several factors:
Tank Size: Larger tanks take longer to pump.
Accessibility: If we need to dig to find and access the lids, it adds to the labor cost. Installing risers eliminates this fee for future services.
Disposal Fees: Waste must be taken to an approved treatment facility, and these fees are part of the service cost.
Location: Your home's location can influence travel time.
Though often used interchangeably, pumping refers to using a vacuum truck to remove all the liquid and solid contents from your tank. Cleaning is a more thorough process that might include hosing down the interior walls and cleaning the effluent filter after pumping. For routine maintenance, pumping is the essential service that removes the problematic solids.
Generally, no. Your septic tank already contains all the natural bacteria it needs to break down waste. Most additives are unnecessary, and some can even harm your system by adding solids, killing beneficial bacteria, or contaminating groundwater. We do not recommend using them. Your tank will still need regular pumping regardless of any additives used.
This is the most common question we get, and it's a sign your system is working correctly! A septic tank is designed to be full of liquid to allow for the proper separation of solids. As soon as you use water in your home, the tank will begin to refill with liquid effluent. This is normal. What we removed during the septic tank pump out were the years of accumulated sludge and scum layers at the bottom and top. You should only be concerned if you see water levels above the outlet pipe, sewage backing up, or pooling water in your yard. Otherwise, a full tank of liquid is a healthy tank.
