Swiss Alpine Road
Builder: Ensign Custom Homes
Midway, UT
This job highlights our custom built distribution box, which is the central point that directs water throughout the drainfield. Since we often encounter issues with distribution boxes and aren’t satisfied with the options on the open market, we build our own. This distribution box is made out of 24” Ipex heavy duty PVC with a sealed fiberglass bottom, 4” water tight grommets, and a locking 24” fiberglass lid. This not only ensures that the drainfield works properly, but also makes it so that the system can be maintained and serviced for the life of the home and beyond.
Green Grove Drive
Contractor: Millhaven Homes
Sundance, UT
The first alternative system permitted in Utah County, this system was originally permitted and installed back in 2007. When installed, it replaced a failed holding tank. The textile filter that was installed on this site was the first of its kind and groundbreaking technology for the state of Utah at the time. The original cabin that this system served was demolished in 2021 and a larger home was built in 2022. Most of the system’s original components were still in great shape and were incorporated into the new system to serve the larger home. The installation of the new system was challenging because of the tight working conditions, groundwater, proximity to the Provo River, and trying to preserve the old growth trees. Getting the 20,000 lb tank in and set at this location required working next to and underneath extremely large trees.
Tollgate Elk Road
Contractor: 4pnt Construction
Architect: Haven Cabins
Wanship, UT
This site had the challenges of expansive clay soil, groundwater, proximity to open water, and the logistical challenges of mobilization in Tollgate Canyon. The site features old growth trees and we stepped up to the challenge of not pulling a single one out during the process of setting heavy tanks and installing the drainfield.
Eleanor Lane
Sundance, North fork of the Provo River
​This system, installed in 2011, had a failing holding tank right next to the North fork of the Provo River. The holding tank not only presented a problem for the cabin but was contaminating the stream. We were able to get a variance for a 45-foot easement from the river to install an alternative system for this cabin. The location presented many challenges: tight access, groundwater, limited working space, setback from the river, and an extremely steep hillside. The water coming out of this system today is crystal clear, odorless, and poses no risk to the protected body of water it sits next to. Over a decade later, the system still has it original components and continues to clean and treat the water.
Old Oak Road
Emigration Canyon
This features a custom tank with access risers over the inlet and outlet. It was designed to be maintained and installed with minimal destruction to the Gambel oak on the property.
Snowberry Ridge
Contractor: Tri City Construction
Architect: Upwall Design
Emigration Canyon, UT
We were fortunate enough to be part of the team that executed this architectural masterpiece at the top of Emigration Canyon in 2012. This project was made challenging by bedrock, steep slopes, and very limited soil to work with.
Over a decade later, it’s hard to tell where the drainfield is installed because the site and vegetation have recovered so well.
Old Ranch Road
Contractor: Superior_CustomHomes
Park City, UT
The site for this project has very dense expansive clay soils, limited space and a setback from a detention pond. All of these components required an alternative system to be implemented.
Old Bridge Road
Sundance, UT
With under 500 square feet of space for the entire septic system, this project that sits right on the North Fork of the Provo River was among the most logistically challenging we’ve ever tackled. In addition to the limited space, our team had to work around the difficulties of groundwater, tight access, an extremely steep hillside, and lots of trees.
Mile 23 Road
Contractor: Davies Design Build
Sundance, UT
Right on top of the North Fork of the Provo River, this site presented the additional challenges of steep ravines, a protected stream, groundwater, limited space, and old-growth trees. Our team also navigated a wooden bridge with tight weight limits, in addition to harsh winter weather on the day we set up the tanks.
Staker Parsons
Jack B. Parson Company
Heber City, UT
Installed in 2007, the alternative system for this industrial building was required due to the environmental sensitivity of the site — mere feet above the Heber Valley's aquifer. It still produces clean water nearly two decades after installation.
Argento Business Park
Charleston, UT
Sitting about 60’ above the Heber Valley's protected aquifer, this industrial complex has extremely tight restrictions on what it is allowed to discharge into the ground. Because of the building's water usage and Wasatch County’s nitrogen requirements, all the wastewater from this building goes through an alternative septic system where it is cleaned and treated to an extremely high standard. The system is tested several times a year for nitrogen levels to ensure that the water coming out of this system is not impacting the aquifer below.
Promontory Gate House
Golf Club & Community
Browns Canyon, UT
Working in extremely tight conditions and limited space to squeeze in a tank between several other utilities, we only had inches of clearance on either side of our tank. This system pumps across the parking lot to a drainfield 100 feet away. As always, the installation included two access risers over the septic tank and a custom distribution box in the drainfield.
Back 40 Grill
Heber City, UT
Back 40 Grill purchased this property in 2015, and as their business thrived, their needs quickly outgrew the building’s original septic system installed in the 1940s.
Lambs Canyon
Contractor: Paulson Construction
Salt Lake County, UT
Lambs Canyon is located in Salt Lake County’s watershed protection zone. This area is so protected that dogs and open-water swimming are banned, as the snow melt and runoff from this area feeds directly into the water supply for the Salt Lake Valley. Up until 2025, all septic systems were banned, but through years of documented alternative septic system success, we were able to work with Salt Lake County to get such systems approved in this protected zone.
Black Cliffs Equipment
Formally Known as Valley Kubota
Heber City, UT
This was the first permitted alternative septic system in the state of Utah. Permitted in 2006 and installed in 2007, this system has been cleaning and treating waste water for nearly 2 decades. The site has limited space, sits on top of a protected water table, and is in close proximity to multiple drinking water wells. The water table is so shallow that the tanks required concrete casts around them for counter buoyancy.
Preserve Red Hawk Trail
Contractor: PJ Builders
Landscaper: Optimo Landscaping
Park City, UT
This site required an alternative septic system due to the presence of expansive clay. Conventional septic systems have biologically active water that binds in clay and creates a slimy film in the ground, leading to drainfield failure over time. This beautiful home has an alternative system that will clean and treat the water, preventing drainfield failure. We were able to fit this into the tight building envelope and minimize impact to the surrounding property.
Emigration Canyon
Failed Drainfield
Clients often approach Alternative Onsite Solutions when a conventional septic system fails. In this case, the entire system failed and needed to be redesigned and upgraded to meet current code.
Moose Hollow, Park City, UT
Upgrading a failing system with minimal landscape disturbance
One of the more technical projects we’ve accomplished, this job required two 1500 gallon concrete tanks which had to be lowered over 40 feet. We installed the drainfield in two sections in order to preserve the surrounding old growth trees and scrub oak on the property.
Midway, UT
Estate home on the Provo River
Laying within 1000 feet of the Provo River, the water coming out of our treatment system is so clean that it does not pollute the surrounding groundwater.
