Trying out the New Onsite Wastewater Treatment System Assessment Tool

Through funding from U.S. EPA, a team at the Illinois State Water Survey with the help of NOWRA and RCAP developed the new Onsite Wastewater Treatment System assessment tool (OWTS tool). The OWTS tool was created as a companion to the Well Assessment Tool, which has been utilized by RCAP’s Technical Assistance Providers (TAPs) and other health professionals to help people across the nation evaluate their private wells.

The OWTS tool allows the assessor to collect contact information, landscape and geology details, and general information about the system and house. There is a checklist for site observations as well as miscellaneous questions to make sure you fully understand how the system is being used.

Once the OWTS tool was finalized, Steve Wilson and Sallie Dolan from our WaterOperator.org team headed out to perform some OWTS and well assessments. The first stop was close by in Piatt County. The homeowners have only lived in the house for a year and a half, so they were curious to learn as much as they can about the well and OWTS. 

The well was of good construction and had no obvious issues. It did have to be shocked with chlorine prior to them moving in, so we recommended they have the water tested for bacteria, nitrates, and that they have a broad panel test done. The home has a water softener and charcoal filter, but the homeowners did not know why they were added to the system. Identifying what metals, minerals, etc. are in the water will help them understand why they have these components.

The OWTS is in the backyard which slopes to a floodplain of the small drainage ditch/creek that runs along the northside of the property. It consists of a Delta Whitewater aerobic tank with chlorinator. The discharge pipe delivers the effluent into the creek floodplain. The homeowners have planted native wetland plants in the area which helps prevent water from standing and beautifies the area.

The 50-gallon tank had to be pumped within the first six months of them living in the home. The homeowners switched to septic-friendly toilet paper and learned the dos and don’ts of what goes into the system, yet it needed to be pumped again less than a year later. The previous owners reported that they never had a similar problem.

Three bedrooms and a family room are in the walk-out basement. Sallie’s theory is that moving trucks drove across the pipe while accessing the walk-out basement during move in. This would have caused the pipe to break and allow sediment to flow into the tank. We are hoping to be on-site when the system is scoped to see if this theory is correct.

The second home we visited was to our east in Vermilion County. The homeowner explained that a “wetland” had formed at the edge of his property which was full of leopard frogs. When we pulled up driving directions on Google maps, we knew that there was an issue with the system. The satellite image clearly showed the outline of a septic tank with lush, green grass growing in three lines while the rest of the yard was brown and dry. The homeowner had already acquired the sewage permit, and the as-built drawing matched up perfectly with the lines on the Google maps image.

The assessment revealed that the homeowner had built a two-bedroom addition to the house soon after it was purchased, taking it from a four-bedroom home to a six-bedroom one. Both homeowners work from home most days, they have three children who live at home, and older children who visit frequently. The “wetland” was an area of lower elevation just beyond the drain field where water from the system was pooling. We recommended that an OWTS installer who is registered with the local health department be contacted to determine if the system is now undersized for its current use. 

At first, the well log for this property could not be located. Luckily, the manager of the well and sewage programs at the local health department knew the site and was able to find the log for us. The well was a bored well with a buried slab. A 6-inch casing was placed from 12 inches above the surface to 28 feet deep, and then a 4-foot well was bored from 28 to 52 feet. According to the well log, it is topped with 28 feet of clay, which helps protect the well from surface water contamination. We also recommended that the soil be sloped around the well head to help protect it. Annual testing for coliform and nitrates is highly advised as they are indicators of potential contamination.

In both cases the assessment did its job to help identify areas of concern with the onsite wastewater treatment systems. The homeowners are more informed and can now take the next steps to contact a professional pumper/installer to help correct any issues found. 

The OWTS and well assessment tools can be found on our sister site, PrivateWellClass.org.

If you would like an assessment done on your well and/or OWTS, contact your local RCAP office.

Onsite Wastewater System Basics & Maintenance

Decentralized or onsite wastewater systems are used for collection, treatment, and dispersal/reuse of wastewater from individual homes, clusters of homes, isolated communities, industries, or institutional facilities, at or near the point of waste generation. These systems are regulated at the state level, but not federal level.

We have 553 resources (and counting) on Decentralized Wastewater Systems in our Documents Database that provide valuable information on this topic. You can search for documents about financing onsite wastewater treatment systems, septic system basics before you buy a property, how to build a decentralized wastewater training program, and many other useful guides that will help you to maintain your septic system to ensure safe and clean water for your family or community.

To access the wealth of knowledge on Decentralized Wastewater within our database just select "CATEGORY" in the dropdown then choose "Decentralized WW Systems." Once you make that selection, a second dropdown will appear where you can choose "HOST," “TYPE,” or “STATE” to narrow the search even further. If you have a specific search term in mind, use the “Keyword Filter” search bar on the right side of the screen.

Careers in Decentralized Wastewater | Onsite Overview #1

The decentralized wastewater sector has thousands of well-paying jobs to offer, so why is the field experiencing a shortage of qualified workers? According to the U.S. EPA, “there are many reasons for this shortage, including the high number of existing systems that require routine maintenance, an increase in the number of systems installed annually, and an aging decentralized workforce that is expected to retire in high numbers over the next several years.” Due to these factors, the need to recruit and train new decentralized wastewater professionals is more critical than ever. We have compiled a list of resources to get you started if you are interested in starting a career in the field of decentralized wastewater or just interested in learning more.

Septic System Contamination Risks

Can a septic system contaminate a well?

Have you ever thought about where the water goes when you flush a toilet? If you have a septic system, this question may be more important than you think. Whether it is the largest advanced wastewater treatment plant in the world or the septic system in your back yard, all wastewater systems need regular maintenance. This will not only extend the life of your system, but it will also help prevent it from potentially contaminating the surface water and groundwater.

How does a septic system contaminate the surface water and groundwater?

Water from your toilets, showers, and other appliances contains harmful bacteria, viruses, and nutrients that could make you sick if it were to enter your well without being properly treated first. Maintenance issues like a full or cracked septic tank or a plugged drainfield can cause untreated wastewater to enter the surface water or groundwater.  
According to the United States Environmental Protection Agency (EPA), the most serious documented problems involve contamination of surface waters and ground water with disease-causing pathogens and nitrates.

Let’s take a peek at a conventional septic system and see how contamination can occur:

Your House:

• Most of the wastewater will generate from the kitchen and bathroom. Watch what you put down your drains. 
• Remember the three P’s: poop, pee, and (toilet) paper. Those are the only things that should be flushed down a toilet. 
• Avoid flushing other chemicals or medications down the drain or toilet as they could contaminate your well. 

Septic Tank: 

• Wastewater exits the home through a pipe and enters the septic tank which is buried and watertight.
• The solids settle at the bottom forming sludge, while fats, oils, and grease float to the top and form scum. Sludge is broken down by microorganisms that also destroy some of the contaminants in the wastewater. 
• If a tank is leaking, contaminated wastewater will exit the tank before it is treated. A septic tank needs serviced and pumped on a regular basis to ensure it is working properly.

Drainfield: 

• In your yard, a series of shallow trenches were placed to create the drainfield. The partially treated wastewater flows from the septic tank into the drainfield and slowly filters down through the soil until it reaches the groundwater.  
• Overloading your drainfield with too much water or having it clogged with solids will cause sewage to surface in your yard or even back into your house.

Treatment in the Soil: 

• Most bacteria, viruses, and some nutrients are removed when the wastewater filters through the soil.
• Soil cannot remove all medicines, cleaning products, and other harmful chemicals, so they pose the risk of entering the groundwater. 
• Wastewater that surfaces in the yard may contaminate your drinking water through an unsecured cap or cracks in the well casing.

Groundwater: 

• Groundwater is water that is beneath the Earth’s surface and is held in the soil or in the pores and crevices of rocks. 
• Any contaminants that remain after leaving the septic system may seep into the groundwater. 
• The biggest risk for a well to become contaminated is if it is in the path of groundwater flow beneath a septic system.

RCAP’s Onsite/ Decentralized Program

RCAP (Rural Community Assistance Partnership) has an onsite/decentralized program that provides training, technical assistance, and financial resources to assist individual homeowners, neighborhoods and entire communities that rely on inadequate septic systems for their waste disposal. 

This program is mostly funded by U.S. EPA through the Rural Treatment Works and National Priority Area 2 grants. RCAP can offer hands-on training with community members, sanitarians, and any professionals who work with onsite systems as well as technical assistance. RCAP has been participating in the Biden administration’s Closing America’s Wastewater Access Gap Community Initiative in six of the 11 pilot communities located in persistent poverty/ disadvantaged areas.

Recently, we spoke with Sarah Buck, RCAP’s Chief Programs Officer, and she provided more information on this valuable resource for anyone working with onsite/decentralized wastewater systems. 

How does this program allow RCAP to help people with onsite/decentralized systems?

There are many ways that this program can help!

• With technical assistance providers, we can help set up a responsible management entity (RME) for decentralized systems.
• We’re able to do mapping activities to map septic systems in a community.
• We can look at areas with high concentrations of septic systems that pose environmental & health risks and help them review all of their options including interconnecting them or assisting with setting up a publicly owned water treatment works or decentralized system.
• We can help find funding to fund these types of projects in disadvantaged communities.

What are the eligible areas?

• Training and technical assistance generally is for communities of 10,000 or less in all 50 states and the US Territories including on Tribal lands/for Tribal septic owners.

Is there financial assistance available?

• Most of RCAP’s regional partners participate in the USDA Decentralized and Well Revolver Fund which provides funding that well and septic owners can use for replacements or updates.

How to apply for assistance? 

• Go to RCAP’s website and fill out the “Get Assistance” Form which will go to someone at the national office. They will then send that form to a regional partner near you to set up a technical assistance consultation.
• Find your local provider on RCAP’s website and contact them directly.
• Fill out U.S. EPA’s Water Technical Assistance Request Form and be assigned a provider that way.
