Version 4.0 (04/03) \ Pagel of 8
HOLDING TANK MANAGEMENT PLAN
This Private Onsite Wastewater Treatment System (POWTS) has been designed, and is to be installed and
maintained according to Comm 83, Wis. Admin. Code, the Holding Tank Component Manual (SBD-10571-P
6/11/1999), and the St. Croix County Sanitary Ordinance
1. This POWTS is designed to accommodate an estimated domestic wastewater [low of 400.0 gpd.
2. The owner of this POWTS is responsible for system operation and maintenance, including all provisions in
the attached Holding Tank Servicing Contract and Maintenance Agreements.
3. Each time the wastewater in the tank reaches 90% of the tank(s) capacity or a level of 12" below the inlet
(at which time the alarm will activate), the pumper listed in the current Servicing Contract must be called to
empty the tank's contents and dispose of them in accordance with NR 113, Wis. Adm. Code.
4. At each service event, the service provider should visually inspect the condition of the tank, risers and
manhole cover(s) and verify that the alarm system functions and manhole locking devices are present.
Discrepancies are reported to the owner in a timely manner for corrective action. All corrective actions
shall comply with the county sanitary ordinance and Comm 83 and 84 Wis. Adm. Code.
5. All service events or inspections of this POWTS shall be reported to the county within 10 business days.
6. The owner may not remove any of the wastes from the holding tank(s), or cause such wastes to be
removed by any person not authorized to do so under Ch. 281, Wis. Statutes. The discharge of wastes
tank to the ground surface, including intentional discharges and discharges caused by neglect, constitutes
a failing POWTS and may result in issuance of correction orders or a citation by the county or state.
7. No one should enter a holding tank for any reason without being in full compliance with OSHA standards
for entering a confined space. The atmosphere within these tanks may contain lethal gases, and rescue
of a person from the interior of the tank may be difficult or impossible.
8. In the event that this POWTS fails and cannot be repaired, a code compliant replacement holding tank
may be installed in the same location (a new sanitary permit is required for such a replacement). Con-
nection to municipal services would also be considered at this time if they are deemed available to the
property.
9. If this POWTS is replaced, or its use discontinued, components no longer in use it shall be abandoned in
accordance with Comm 83.33 Wis. Adm. Code.
10. If there is a problem with, or question about this installation, the following persons should be contacted:

b. Service Provider, Powers Liquid Waste Management Phone: (715 246-5738

The specifications and/or plans for this plumbing product have been reviewed and determined to be in compliance
with chapters SPS 382 through 384, Wisconsin Administrative Code, and Chapters 145 and 160, Wisconsin
Statutes.
The Department hereby issues an approval based on the Wisconsin Statutes and the Wisconsin Administrative
Code. This approval is valid until the end of March 2020.
This approval is contingent upon compliance with the following stipulation(s):
• This tank must be designed to withstand the pressures to which it will be subjected.
• The manufacturer must keep at the manufacturing plant a set of plans and specifications bearing the
department's stamp of approval. The plans and specifications must be open to inspection by an authorized
representative of the department.
• This product is approved to use the following:
- Four inch pipe inlet located in the edge of the tank cover.
- Four inch discharge opening in riser.
- Two inch schedule 40 PVC cast in riser for electrical wiring.
- Four inch pipe openings located near the bottom of the side or end wall for siphon, pump and holding tanks.
- Steel locking cover for the access opening.
- Pipe materials constructed in conformance with Table SPS 384.30-2 or 384.30-11, Wis. Admin. Code poured
into tank cover or access cover.
- Eight inch threaded plugged opening in access cover.
- Six-inch diameter opening in lower portion of the interior wall for siphon, pump and holding tanks.
- Department approved effluent filter installed in accordance with the product approval for the filter including a
properly sized and located access opening for service and maintenance.
- Press Seal "Cast-A-Seal" gasket by Press Seal Gasket Corp.
• BEDDING: After excavating to grade, the floor of the tank hole must have all rocks removed that are golf ball
size or larger. This applies to soil that is not hard packed clay or rock. If the floor of the hole is hard packed clay
or rock, then the hole must be dug deeper to accommodate a lift for sand (no rock) at least 3 inches deep to
bring the excavation to the desired grade level.
NOTE 1: Sand is required for tanks that are going to be buried with five or more feet of dirt. Clean no clay
content gravel can be used for tanks that have less than five feet of dirt. The rocks that are bigger than golf balls
should be removed. The sand rock ratio should be at least 50% sand. Clay should not be distributed along the
floor of the tank.

SKAW PRECAST

March 9, 2015
Product File No: 20150015
NOTE 2: The bottom of the tank hole should be graded as such. Keep the center of the hole about 0.5 to 1.0
inches lower that the sides of the hole where the tank walls will rest. If there is a high spot in the middle of the
hole, the tank will settle and push up or crack the floor of the tank. The floors are only three or four inches thick
and are not made to withstand the pressure of the dirt on top of the tank. The cover and walls are made to
withstand this pressure so it is very important not to have the center of your hole graded too high.
• BACKFILL: When a tank is ready to be buried/backfilled, start by using a backhoe and gently place material on
the cover of the tank. At the same time gently place material starting at the corners of the tank. Allow the
material placed on the corners to slide down towards the center of the side walls and ends of the tank. This
should be done at all corners of the tank at the same time so the tank does not slide around in the bottom of the
hole.
NOTE 1: Too much material applied to any one side of the tank without material on the other side or top of the
tank may cause the sidewalls of the tank to crack or slide the tank horizontally in the bottom of the hole.
NOTE 2: When applying any material as backfill or bury always lower your backhoe bucket to an elevation near
(within 12 inches) the grade of the tank cover and empty the bucket of the backhoe slowly. This prevents a large
amount of material from "plopping" downward suddenly causing undue stress to the vertical walls and cover of
tank.
NOTE 3: Rocks or stones any larger than 4 inches in diameter should not come into contact with any part of the
concrete tank structure at any time.
WARNING: Stones or rocks larger than 4 inches in diameter could damage the structure of the tank. This can
happen especially if the larger stone or rock falls or rolls into contact with any part of the tank structure.
When finish grading is being accomplished, never drive equipment directly on top of the tank installation. Do not
allow tires or tracks of equipment to travel parallel to the tank on material that has just been used to fill the void
between the tank and material that has not been disturbed.
The department is in no way endorsing this product or any advertising, and is not responsible for any situation which
may result from its use.
Sincerely,
Glen Jones, M.S.
