"I hired Double M to build a million gallon liquid manure storage pit for my farm. The project took 5 months and I was amazed at the work they did. This was a very complicated project. They kept me informed almost every day on what they were doing and if I was satisfied with the work. If I had a concern, they worked with me to resolve the issue. I highly recommend them and plan on working with them in the future."

Septic Tanks FAQs, answered by experts

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”

Rainwater doesn't have a direct impact on the amount of water in your well. Instead, the majority of rain runs off into other bodies of water such as streams, rivers, and lakes. These bodies of water may sometimes function as the area’s reservoir and create aquifers, which then help to replenish your well.

Modern septic tanks have two lids: one that covers the inlet where wastewater flows into the tank and one that covers the outlet where the treated water flows out to the drain field. However, older septic tanks installed before 1975 may have only one lid. Because septic tanks last 20 to 40 years, if yours only has one lid, it may be time for a replacement.

Common signs that a septic tank is full include plumbing issues, odors, and changes in your yard. You may notice wastewater or sewage backing up into your home's drains, or that sinks, tubs, and toilets are draining slowly. Gurgling or bubbling sounds from the pipes are also a key indicator. Outside, you might smell foul sewage odors around your house or the septic tank area. Look for pooling water, spongy soil, or a marshy environment around the drain field. Another tell-tale sign is a patch of grass over the septic system that is suddenly lusher and greener than the rest of your lawn. If you notice any of these signs, you should contact a septic professional for an inspection and pumping.
