"The guys did an excellent job in my opinion. They had to do some excavating to get down to the pipe. The complete pipe was replaced, not patched in. The septic tanked was pumped out, inspected, and an access cover was installed above the ground for future cleaning. The guy did everything to the tee that he told me he was going to do before he started. He completed the job in one day like he said he would, and he put back all the landscaping back exactly how it was to begin with. I would have Western Septic come back in a heartbeat and do any repairs that I have in the future. Super nice guy, friendly, and was very reasonably priced for all the work he performed for me. 100% satisfied, that's for sure."

Septic Tanks FAQs, answered by experts

Depending on local conditions, a deep well may be a better choice than a shallow well. Deeper well depth accesses groundwater that has been naturally filtered through many layers of soil and rock. This reduces surface contaminants and may offer cleaner water, but deep wells cost more money to build and maintain. The water may be harder and have higher radioactivity, too. 

A properly installed and maintained septic drain field (also known as a leach field) can last up to 50 years, though the average is around 20 years. However, factors like poor soil conditions, heavy usage, or improper maintenance can significantly shorten its lifespan to 15-20 years.

To extend the life of your drain field:

  • Schedule Regular Inspections: Have the entire septic system, including the drain field, inspected every two to five years to catch problems early.

  • Protect the Area: Avoid driving heavy vehicles or placing heavy structures over the drain field. Plant only grass or other lightweight vegetation with shallow roots over the area.

  • Maintain the Septic Tank: Proper care of the septic tank, including regular pumping and avoiding harmful chemicals, prevents strain on the drain field.

Be aware of signs of failure, such as strange odors, standing water, or unusually lush grass over the field, which indicate your system may need professional attention.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.
