What about septic pumping & inspections?

Even the most committed DIY homeowners rarely deal with servicing or maintenance on a septic tank. To avoid problems with your system, we recommend septic tank pumping every 2 to 5 years. This interval can vary based on factors like the volume of wastewater your household generates, the type of septic system you have, or other issues such as clogs or backups.

Ensure your system runs smoothly and efficiently with our comprehensive septic services:

Pumping and cleanouts. We prevent deposits of sludge and scum from rising and contaminating the drainfield area, or clogging pipes with solids.

Inspections. We examine your entire system, including the tank, sludge layers, outlet baffles, effluent filters, drain fields, and other components like septic dose pumps, and distribution boxes. We can perform any needed repairs at that time, install risers and tank lids, and replace outlet baffles.

Recommendations. You can follow a few simple practices to keep your waste system running smoothly and the surrounding ground water and environment healthy.

How much does a septic system cost?

An average cost for an entire septic system replacement in Northern Colorado is $25,000 to $30,000.

If just a leach field is replaced, cost is $18,000 to $30,000, worst case.

For tank replacements, depending on accessibility, normal cost is $9,500 to $11,000.

The cost also depends on factors such as:

  • Your soil type and soil properties
  • Your lot size and ground slope/grade
  • Your home size and number of occupants
  • The location of your system

Septic systems can range in cost anywhere from $17,500 to $50,000. We will answer these questions, and ensure your system fits your needs. We can even upgrade your system in the event you add on to your home.

Locating your septic tank & drainfield

In most cases, we bring in a mini-excavator to locate where your septic tank is buried on your property.

We use additional clues, such as where the sewage drain exits your basement, and the positioning of your well. We can quickly pinpoint the location and dig down to the lid cover based on these and other signs.

Watch for signs of a failing septic system

Is your septic system over 25 or 30 years old? You may need to upgrade your system. Recognizing symptoms like the ones below can help you avoid a potentially big wastewater management problem.

Is there a sewage smell around your drainfield?

Sewage odors can be a symptom of untreated wastewater surfacing into the surrounding soil. It also can be a normal and contained by proper sealing of risers or inspection ports. We can diagnose and fix the odor issue.

Is there ponding water or lush grass growing over the drainfield?

If you notice standing water, damp spots, or very green grass over your septic tank or leach field, the effluent may not be properly draining into the leaching material.

Even when pooling water isn’t visible, we can check water levels using a probe, or examine the soil.

Are your bath, showers and sinks draining slowly?

Sluggish drains and toilets can involve a backup from your septic tank into your household plumbing. 

A thorough examination of your septic system is often required to locate and deal with these concerns.

Common Septic Systems in Fort Collins, Loveland and Northern Colorado

Conventional Gravity Septic System

In Northern Colorado, the standard gravity system is widely used. Because this system involves a slope, which helps wastewater exit the home to the septic tank, a gravity system uses no pumps for that process.

This makes a gravity system more economical and energy efficient than most other systems. Once wastewater moves into the septic tank, it flows out of the tank into either a header or a distribution box, which evenly dispenses the effluent into the chambers of the drainfield.

Mound/Sand Filter System

If you have a high groundwater table, or a problem with the soil being impermeable, a conventional septic system usually will not work correctly. A mound/sand filter system is a drainfield that allows for the treatment of wastewater under these types of circumstances.

The construction of a new mound system still includes a septic tank. However, effluents are sent to a second tank (pump tank), which distribute the wastewater and partially treats it through the mound sand. When we install a mound system, we put down approximately 3 feet of concrete sand, before installing the leach field on top of the sand.
