Septic & Storm Shelter Services You Can Count On

When your septic system is running smoothly, you don’t think about it. When it isn’t, the disruption is immediate—slow drains, odors, soggy yards, or backups that turn into an emergency fast. TGW Septic & Storm Shelters helps homeowners and property owners protect their investment with straightforward service, clear communication, and work that’s built to last. Whether you need a new septic system install, troubleshooting and repairs, or a maintenance plan that prevents costly failures, our goal is simple: keep your system reliable and your property protected.

How septic systems work (and why problems happen)

A septic system is essentially an on-site treatment setup. Wastewater leaves your home and enters the septic tank, where solids settle to the bottom and oils float to the top. The clearer liquid then moves to the drain field where it disperses and filters through soil. When the tank is sized correctly, installed properly, and maintained on schedule, everything stays balanced. Problems usually happen when solids build up from missed pumping, water usage overwhelms the system, or the drain field gets damaged or clogged.

The most important thing to know is this: many septic “emergencies” start with small warning signs. Catching them early can save the drain field, reduce repair costs, and prevent messy surprises.

Common warning signs to watch for

  • Slow drains, gurgling sounds, or frequent clogs throughout the home
  • Odors inside, or outside near the tank and drain field area
  • Standing water, spongy soil, or unusually green grass above the drain field
  • Backups after heavy water use (laundry day is a common trigger)
  • Alarms, pump issues, or breakers tripping on systems with electrical components

If you notice any of these, it’s better to address it quickly than wait for a full blockage or drain field failure. We can inspect the system, identify what’s actually causing the problem, and recommend the right fix—not a temporary patch.

Simple maintenance that protects your system

Septic maintenance doesn’t have to be complicated. The goal is to protect the tank from overflow, protect the drain field from compaction and clogs, and keep the system stable over time. A few habits make a big difference:

  • Schedule pumping based on household size and usage (don’t guess—inspect).
  • Fix running toilets and leaks quickly to avoid overloading the tank.
  • Spread out laundry loads instead of doing everything in one day.
  • Avoid flushing wipes, grease, and harsh chemicals that disrupt bacteria.
  • Keep vehicles and heavy equipment off the drain field area.

If you’re not sure where your tank or drain field is located, we can help you identify it and build a practical maintenance plan that fits your property.

Quick FAQs

How often should a septic tank be pumped?

It depends on household size, tank size, and usage. Many homes fall in a 3–5 year range, but an inspection is the best way to avoid pumping too early or too late.

Can I drive or park on my drain field?

It’s not recommended. Weight can compact soil and crush lines, which reduces the drain field’s ability to disperse and filter wastewater.

What’s the best first step if I suspect a septic issue?

Reduce water usage and schedule an inspection. Finding the root cause early is the fastest path to an affordable solution.
