Summer is officially here! Between backyard barbecues, family road trips, pool parties, and kids home from school, summer is easily the busiest season of the year for most households.
But while you are out soaking up the sun, your septic system is working overtime. Increased water usage from extra laundry, guests, and summer showers can put massive stress on your underground plumbing. At Sunshine Septic, we want to make sure your summer stays stress-free, which is why we’ve put together this ultimate summer guide to keeping your septic system running beautifully.
1. Watch Out for the “Summer Microbial Surge”
Did you know that summer weather actually changes the biological environment inside your septic tank?
Septic systems rely on anaerobic digestion (natural bacteria breaking down waste) to function properly. While warm weather can sometimes accelerate the breakdown of organic solids, researchers have found that typical summer heat can also lead to a massive spike in bacteria levels. A study published in the journal Water revealed that E. coli concentrations within a septic tank can increase up to 100-fold during hot summer weather, drastically increasing the microbial load leaving the tank.
If your system is already struggling or hasn’t been cleaned out in a while, this spike in bacteria combined with heavy water use can easily lead to unpleasant odors or system failures.
2. Space Out Your Water Use
With kids home from school and guests visiting for weekend cookouts, your daily water volume naturally ticks upward. According to the EPA, overloading a septic tank with too much water in a short period reduces the “retention time” that solids need to settle to the bottom.
When unclarified wastewater is forced out of the tank too quickly, it carries solid scum and sludge straight into your absorption field (drain field), which can permanently clog the soil.
-
The Fix: Avoid doing five loads of laundry back-to-back on a Saturday morning. Space out your water-heavy chores—like running the dishwasher or washing clothes—throughout the week so your tank has time to process the flow.
3. Protect Your Drain Field from Summer Fun
Your drain field is a sensitive area of unsaturated soil that filters out dangerous nutrients and pathogens before they can hit the local groundwater supply. Because this soil needs oxygen to effectively treat the wastewater, keeping it loose and uncompacted is vital.
-
Keep Cars and Heavy Equipment Off: Planning a summer landscaping project or having friends over to park in the yard? Never drive or park vehicles over your septic tank or drain field. Heavy weight crushes pipes and compacts the soil, cutting off the oxygen supply and triggering a system failure.
-
Watch the Landscaping: While planting summer flowers is great, make sure you don’t plant deep-rooted trees or shrubs near your lines. Tree roots love moisture and will gladly break into your septic pipes to get it.
4. Know the Warning Signs of a Summer Failure
Septic system failures generally show up in two ways: treatment failures (which happen out of sight underground) and visible failures. Keep an eye out for these classic signs that your system needs immediate attention:
-
Slow-draining sinks or showers
-
Gurgling noises in your pipes
-
Sewage backing up into household fixtures
-
Unusually lush, bright green patches of grass over your drain field
-
Foul odors drifting through the yard
