Holding tanks shall be considered on an individual basis. Three
complete sets of plans, as required in Wisconsin Administrative Code
§ SPS 383.22, shall be submitted to the County issuing agent
for each request to install a holding tank.
A.
One- and two-family dwellings. Minimum liquid capacity of a holding
tank for one- and two-family dwelling applications must not be less
than 2,000 gallons or five times the estimated daily wastewater flow
determined in accordance with § SPS 383.43(3), (4), (5),
Wisconsin Administrative Code, whichever is greater.
B.
Public facilities. Minimum liquid capacity of a holding tank for
public facilities must not be less than 2,000 gallons or five times
the estimated daily wastewater flow, whichever is greater, as determined
in accordance with § SPS 383.43(6), Wisconsin Administrative
Code.
A.
Applicants for holding tanks shall first receive approval from the
local government, and then have a signed and notarized holding tank
agreement recorded in the Register of Deed's office. The holding tank
agreement shall be binding on the owners, their heirs and assignees.
B.
Applicants for holding tanks shall submit a signed and notarized
holding tank servicing contract with a certified septage servicing
operator to the County issuing agent prior to the issuance of a state
sanitary permit. The holding tank servicing contract will remain in
effect until the owner or Wisconsin DNR certified septage servicing
operator terminates the contract. In the event of a change in servicing
contract, the owner agrees to file a copy of any changes to this service
contract or a copy of a new service contract with the County issuing
agent within 10 business days from the date of change to this service
contract. Holding tank servicing frequency shall follow § SPS
383.54(3)(c), Wis. Adm. Code and Section VII of the Holding Tank Component
Manual. The servicing contract guarantees a Wisconsin DNR certified
septage servicing operator is hired for pumping and transport of the
holding tank contents to a Wisconsin DNR approved disposal site meeting
the requirements of Chapter NR 113, Wisconsin Administrative Code.
The servicing contract is necessary to prevent or abate a nuisance
as described in the Wisconsin Administrative Code and § 254.59,
Wis. Stats.
