The KEWAUNEE COUNTY SANITARY ORDINANCE covers all municipalities in Kewaunee County where public sewer is not available.† The purpose of this ordinance is to protect and promote the health, safety, prosperity, aesthetics, and general welfare of the people and communities within Kewaunee County.† The general intent of this ordinance is to regulate the location, design, construction, installation, alteration, maintenance, inspection, management, and use of POWTS and non-plumbing sanitation systems so as to protect the health of residents and transients and to secure safety from disease, nuisance, and pestilence.†

A†Conventional system is one of the more simple systems to install and operate because it is a gravity fed, passive system.† Water runs down hill from the residence to a septic tank and down hill from the septic tank into the treatment/disposal area.† Conventional systems require the greatest amount (deepest) suitable soil - at least 48 inches deep underneath the system.† Suitable soil must be permeable and not have indications of groundwater or seasonal saturation.† Colored indicators within the soil called†redoximorphic features (mottling) are typical indicators of high ground water or seasonal saturation.† Mottling is identified as high or low croma indicators in the soil.† During a soil test a certified soil tester will identify the depth, size, contrast and abundance of any mottling as well as the soil permeability.† For new construction, a soil test for a conventional system must identify an area for immediate development and an area for a†reserve site for future use.†

In-Ground Pressure systems require a lesser amount of suitable soil, but do require a second tank (a pump chamber) containing a pump to provide for pressure distribution of the effluent from the septic tank to the treatment/disposal area.† In-Ground Pressure systems require at least 46 inches of suitable soil underneath the system.† One advantage of this type of system is that it does not need to be down hill from the structure being served because the pump can move the effluent up hill or to a location some distance from the building.† This is a tightly designed system because it needs to meet specific pressure and distribution requirements.

Mound type systems require only 6 inches of suitable soil underneath the system and can be installed on soils with a relatively low permeability.† These systems are very similar to the In-Ground Pressure systems in that they utilize a septic tank and a pump chamber in the same way.† The difference is that the mound system is installed above ground rather than below.† A mound system is created by: 1) placing one foot or greater of sand on the plowed surface of the soil, 2) the distribution piping is then installed in a bed of aggregate above the top of the sand, and 3) the mound is capped with soil to allow vegetation to grow.† This system provides the same level of environmental protection as the previously described systems except it is installed above ground.

At-Grade systems are simply mound systems without the addition of any sand.† These systems require 36 inches of suitable soil underneath the system, rather than the 6 inches required for the standard mound system.

The Holding Tank system is simply as it sounds.† It is a tank, or series of tanks, that contains all the water used by the structure.† The tank contains an alarm system to alert the owner when the tank is full.† When the tank is full, the sewage is then pumped by a pumping service and taken to a municipal sewer treatment plant for treatment and disposal.

The†KEWAUNEE COUNTY SHORELAND ZONING ORDINANCE†applies to all unincorporated areas in Kewaunee County.† The purpose of this ordinance is to further the maintenance of safe and healthful conditions; prevent and control water pollution; protect spawning grounds, fish and aquatic life; control building sites, placement of structures and land uses; and to preserve shore cover and natural beauty.

Kewaunee County Shoreland Zoning Ordinance

Shoreland property owners play an important role in preserving the quality of our lakes, rivers, and waterways. As a shoreland property owner, your responsibilities extend beyond your individual property. How you take care of your shoreland property can impact an entire lake or waterway system. The purpose of this ordinance†is to help guide shoreland property owners, contractors, and others to understand the important provisions and how you can protect our valuable delicate natural systems that include the lakes, rivers, and waterways in†Kewaunee County through good environmental practices.

The†KEWAUNEE COUNTY FLOOD PLAIN ZONING ORDINANCE†applies to all unincorporated areas of Kewaunee County.† The purpose of this ordinance is to regulate floodplain development to protect the public health, safety, convenience, general welfare and tax base of Kewaunee County.

Kewaunee County Flood Plain Zoning Ordinance

It is very important to be aware of the floodplains of Kewaunee County. Controlled development within these areas helps reduce the risk of damage and loss of life during flooding events. Flooding is the #1 natural disaster and flood damage is not covered by most homeowners insurance. In fact, 25% of flood claims are filed by people living in moderate-to-low risk areas. The disaster assistance ó if itís available ó is usually a loan you must repay with interest. This is why it is best to be proactive rather than reactive when it comes to the floodplains of Kewaunee County.
