�� ���� ��� PID# 2511823440013
SAME
This site will be designed for an Above Grade Drain field
The site must remain protected until construction begins.
(This is the responsibility of the owner and or General Contractor)
This site evaluation was completed on September 8, 2016. It is for a type one dwelling
with and estimated flow of 750 gallons per day. Soils information indicated mixed soils
in the upper 12 inches of the soils, requiring a monitoring and mitigation plan to be
developed and signed off by the owner and installer. This system will be considered a
Type III under the city of Orono Septic Code. This system will require 24 +- of the
mixed material within the absorption area, to be removed and re-placed with washed
sand. Three (3) feet of sand will be required under the rockbed to meet the 3 foot
separation from the seasonal high watertable as required by MPCA Agency Rules and
Stand'ards, Chapter 7080,81.
The Mound System design area is 64 feet wide with a length of 110 feet. Pin Flags have
marked the location of the soil borings, plus the boundary of the system. The fill material
to be removed is within the Absorption Area of the mound which is 17 feet downslope of
the rock bed and 80 feet long. The contractor to remove 24+- inches of the top Mixed
Soil Material to reach the original loamy topsoil. This will require about 160 yards of fill
material to be removed.
The proposed system will require(2) 1500-gallon septic tanks, and(1) 1500 gallon
dosing tank. The tanks cannot be deeper than 4 feet from the ground elevation and
manholes must come to the surface,but be higher to not a11ow surface water to enter the
manholes. The pump will need to be sized to deliver 36 gallons per minute with a lift of
l'6feet of total head. The existing septic tank(s) will need to be pumped and destroyec�.
An effluent filter must be installed in the second tank with an alarm system. The filter
must be checked and cleaned on a routine basis—normally use will require the filter to be
rinsed off twice a year(spring and fall). This is the responsibility of the systems
owner.
The set-back for the well from the septic system area must be a minimum of 50 feet for
both the septic tanks and the absorption area. The septic tanks will need to be at least 10
feet from the edge of the house and the absorption field must be 10 feet away from
property lines. It is the responsibility of the owner to identify the property
boundaries for designing and installing the septic system.
The septic system if properly installed and maintained should have no problems treating
effluent in the matter that it was designed for. Nothing other than human waste,toilet
tissues, shower, sink, dishwasher and laundry water should be drained to the septic tanks
and treatment field. If you have water treatment systems other than water softeners, in
ex. Iron filters, they should be diverted from entering the septic system.
Garbage disposals are not recommended, as they will add more solids to your septic tanks
and may allow fine particles to enter the treatment area and clog the system. Daily toilet
bowl cleaners, shower sprays (that are used after every shower), and excessive cleaning
agents may kill bacteria needed to treat septic effluent. Additives are not needed, and are
not recommended in properly maintained septic system.
You should have your septic tanks pumped and inspected for proper maintenance
by �certified pumper every 2 years.
General
The soil conditions have been established at the test hole location only. There may be
variations in soil stratigraphy between and around the borings and interpolation and
extrapolation of the results is not warranted.

The owner has an Subsurface Septic Treatrnent System(SSTS),that is considered a Type
3 under the rules of MPCA. The SSTS system consists of the following: (2) 1500-gallon
septic tanks, (1) 1500 gallon pump tank, and an above grade Mound Drainfield,with a 10
x 63 Rockbed. The new drainfield will be located on filled soils that will be removed
prior to placement of the required 3 feet of sand under the rockbed. City requirements
require that a monitoring and mitigation plan be developed. The first year monitoring
will take place within the first 6 months of the installation, and then yeazly for 3 years.
After that,the monitoring inspecrion will be completed with the routine maintenance of
the tanks every 3 yeazs. A water meter will need to be installed and tied to the water use
in the house,not the outside faucets.

Se tic S stem Mana ement Plan �'
P Y g
for Above Grade Systems
The goal of a septic system is to protect human health and the environment by properly treating
wastewater before returning it to the environment. Your septic system is designed to kill harmful
organisms and remove pollutants before the water is recycled back into our lakes, streams and
groundwater.
This management plan will identify the operation and maintenance activities necessary to ensure long-
term performance of your septic system. Some of these activities must be performed by you, the
homeowner. Other tasks must be performed by a licensed septic maintainer or service provider.
However, it is YOUR responsibility to make sure all tasks get accomplished in a timely manner.
The University of Minnesota's Septic System Owner's Guide contains additional tips and
recommendations designed to extend the effective life of your system and save you money over time.
Proper septic system�fesign, installation, operation and maintenance means safe and clean water!

Keep this Management Plan with your Septic System Owner's Guide. The Septic System Owner's Guide
includes a folder designed to hold maintenance records including pumping, inspection and evaluation
reports. Ask your septic professional to also:
• Attach permit information,designer drawings and as-builts of your system, if they are available.
• Keep copies of all pumping records and other maintenance and repair invoices with this document.
• Review this document with your maintenance professional at each visit; discuss any changes in product
use,activities or water-use appliances.

Homeowner Management Tasks
These operation and maintenance activities are your responsibility. Use the chart on page 6 to track
your activities.
Identify the service intervals recommended by your system designer and your local government.
The tank assessment for your system will be the shortest interval of these three intervals. Your
pumper/maintainer will determine if your tank needs to be pumped.
System Designer: check every months
My tank needs to be checked
Local Government: check every months
State Requirement: check every 36 months every 36 months
Seasonally or several times per year
v Leaks. Check(listen, look)for leaks in toilets and dripping faucets. Repair leaks promptly.
❑ Surfacing sewage. Regularly check for wet or spongy soil around your soil treatment area. If
surfaced sewage or strong odors aze not corrected by pumping the tank or fixing broken caps, call
your service professional. Untreated sewage may make humans and animals sick.
❑ Alarms. Alarms signal when there is a problem; contact your maintainer any time the alarm
signals.
❑ Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. Consider
adding one after washing machine.
❑ Effluent screen. If you do not have one, consider having one added the next time the tank is
cleaned.
Annually
o Water usage rate. A water meter can be used to monitor your average daily water use. Compare
your water usage rate to the design flow of your system (listed on the next page). Contact your
septic professional if your average daily flow over the course of a month exceeds 70% of the
design flow for your system.
o Caps. Make sure that all caps and lids are intact and in place. Inspect for damaged caps at least
every fall. Fix or replace damaged caps before winter to help prevent freezing issues.
❑ Water conditioning devices. See Page 5 for a list of devices. When possible,program the rechazge
frequency based on water demand (gallons) rather than time (days). Recharging too frequently
may negatively impact your septic system.
❑ Review your water usage rate. Review the Water Use Appliance chart on Page 5. Discuss any
major changes with your pumper/maintainer.
During each visit by a pumper/maintainer
❑ Ask if your pumper/maintainer is licensed in Minnesota.
❑ Make sure that your pumper/maintainer services the tank through the manhole. (NOT though a 4"
or 6"diameter inspection port.)
❑ Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4.

Professional Management Tasks
These are the operation and maintenance activities that a pumper/maintainer performs to help ensure
long-term performance of your system. Professionals shoudd refer to the O/M Manual for detailed
checklists for tanks,pumps, alarms and other components. Call 800-322-8642 for more details.
❑ Written record provided to homeowner after each visit.
Plumbing/Source of Wastewater
o Review the Water Use Appliance Chart on Page 5 with homeowner. Discuss any changes in
water use and the impact those changes may have on the septic system.
❑ Review water usage rates(if available)with homeowner.
Septic Tank/Pump Tanks
❑ Manhole lid. A riser is recommended if the lid is not accessible from the ground surface. Insulate
the riser cover for frost protection.
❑ Liquid level. Check to make sure the tank is not leaking. The liquid level should be level with the
bottom of the outlet pipe. (If the water level is below the bottom of the outlet pipe, the tank may
not be watertight. If the water level is higher than the bottom of the outlet pipe of the tank, the
effluent screen may need cleaning,or there may be ponding in the drainfield.)
❑ Inspection pipes. Replace damaged caps.
❑ Ba,ffZes. Check to make sure they are in place and attached, and that inlet/outlet baffles are clear
of buildup or obstructions.
❑ Efjluent screen. Check to make sure it is in place; clean per manufacturer recommendation.
Recommend retrofitted installation if one is not present.
❑ Alarm. Verify that the alarm works. •
❑ Scum and sludge. Measure scum and sludge in each compartment of each septic ancl pump tank,
pump if needed.
Pump
❑ Pump and controls. Check to make sure the pump and controls are operating correctly.
❑ Pump vault. Check to make sure it is in place;clean per manufacturer recommendations.
❑ Alarm. Verify that the alarm works.
❑ Drainback. Check to make sure it is operating properly.
❑ Event counter or run time. Check to see if there is an event counter or run tirne log for the pump.
If there is one, calculate the water usage rate and compare to the anticipated average daily flow
listed on Page 2.
Soil Treatment Area
❑ Inspection pipes. Check to make sure they are properly capped. Replace caps that are damaged.
❑ Surfacing of effluent. Check for surfaced effluent or other signs of problems.
❑ Lateral flushing. Check lateral distribution; if cleanouts exist, flush and clean as needed.
❑ Ponding. Check for ponding. Excessive ponding in at-grade and mound beds indicates
problems.
