Septic System FAQ

Questions about your septic system? Don't worry! We've likely heard them before. Below is a list of commonly asked questions about septic systems, with answers. If you need more information, please don't hesitate to give us a call!

Why Does My System Back-Up?

Septic Systems can back-up or clog due to a variety of circumstances. Please contact us ASAP to discuss your specific situation, and our service representatives can help get this fixed. Here are a few questions we might ask:​

  • When was the last time you had your septic tank professionally cleaned and/or inspected? Extending the service frequency can result in excessive solids build-up, among other issues.

  • Does your system contain an effluent filter? Filters are located at the end of the tank, and are designed to trap solids inside the tank- preventing them getting into the drainfield pipes and soil.

  • Where is the backup occurring? Depending on the fixture location, drain-cleaning services may be necessary to remove clogs.

How Does a Septic Tank Work?

Septic tanks are designed to catch incoming wastewater from a residence or building. Once inside the septic tank, wastewater and solids undergo a treatment period, where bacteria breaks down the wastewater, resulting in separation of the solids. 

Septic Tanks are sized for a minimum two times maximum daily wastewater flow, to allow for a 24 hour retention period where the solids can separate. Once separated, semi-treated effluent (water) enters the drainfield via displacement. 


Drainfields, Lateral Lines, Leach Fields, etc. all perform the same job: treat the wastewater via filtration & digestion. Once water is introduced to the drainfield, it is absorbed into the soil surrounding the lines. Bacteria and organisms inside the soil further digest the wastewater, removing harmful pathogens. Gravity pulls the water down deeper into the soil, resulting in a natural filtration process. Eventually, the treated effluent reaches groundwater, and the process is repeated.

​How Often Should I Have My System Pumped & Inspected?

The answer is the same for everyone: it depends.​

  • A regular pumping frequency is vital to your systems health and longevity. Typical septic systems are designed to be cleaned once the solid levels of the tank reach 25%-30% of the overall tank's capacity. For most homes, this occurs every 2-4 years. More frequent servicing may be necessary due to the age of the system, number of residents, and the capacity of the septic system. 

  • If you can't remember, it's been too long!

What can I do to Protect My Septic System?

We recommend the following simple procedures to lengthen the life of the septic system and prevent costly issues:​

  • Have the system pumped and inspected regularly. Typically, this means once every 2-4 years.

  • Install service access risers, baffles, and an effluent filter. Not only are these items required, but they can greatly extend the life of the system.

  • Don't flush anything that isn't designed for a septic system! This is one of the most important steps. Flushing anything that isn't waste or toilet paper can result in irreparable damage to the system. 

​​How Can I Locate My Septic System?

  • Your local environmental services department should have records of the system, including an as-built drawing. ​If no as-built drawing is available, or if it is incorrect, we have locating services using industry technology & experience to aid in finding the system. 

Do I Need to Be Home For Pumping Services?

  • While it is not mandatory to be home during pumping, we highly encourage homeowners to be present at time of service. Being present helps if there are any issues or potential problems with the system, as our service technicians can show them to you and explain possible options. Typical service visits range from 30-60 minutes in duration.

​​Where Does the Waste Go After it's Pumped?

  • All waste pumped by us is disposed of in an environmentally friendly way, conforming to all state and local laws. Typically, waste pumped out of a septic tank is disposed at a Waste Water Treatment Plant. In certain situations, we may also dispose of the waste via land-application on approved agricultural parcels.

Portable Restroom FAQ

Renting a portable restroom for the first time? Don't know what to expect? Not to worry! We've been asked many questions before from first time renters, as well as seasoned veterans!

​​Will My Restroom Unit be Clean?

  • YES! We use a variety of tools and chemicals to fully clean and sanitize each unit before it is placed on site. Each unit is pressure-washed, scrubbed, and sanitized with a chemical agent before it leaves our shop. For long-term rentals or events where additional services are requested, our vacuum trucks are equipped with modern tools to clean the units while on-site, keeping them stocked, sanitized and clean while in use. 

How Many Restroom Units Will I Need?

  • For Standard Restroom Units, the amount necessary is determined by duration, # of guests or workers, and usage frequency. Each of our standard units are designed to sustain approximately 200 uses, before service is necessary. For construction sites or long-term rentals, this equates to 1 unit per 10 employees, working 40 hours per week. For short-term events or weekend based rentals, we recommend 1 unit per 50 guests per day. 

How Long can I Rent a Restroom Unit?

  • As long as you need it! We have a variety of rental options. These options are broken down into two main categories, Long-Term Rentals (7 days or longer) and Short-Term Rentals (1 Day up to 7 Days). Typically, for events, we deliver the unit on the first business day before the unit will be needed, and pick the unit up the first business day after the unit is used. So, if you're needing a restroom on a Saturday, we would deliver the unit on the Friday before, and pick it up on the Monday after. 

  • For longer rental periods (monthly), we would deliver the unit based on route and availability (typically same-day or next-day service). We would then service the unit at least once a week on a standard route until the unit is no longer needed.​​
