Septic System Seepage Pits
A seepage pit is a well that is lined with a porous masonry in which the household waste discharges from a septic tank and is collected for gradual seepage into the ground, sometimes used as a substitute for a drain field.

Seepage pits were designed for use in area’s were there wasn’t access to the metropolitan sewer system or where a conventional septic system would not function properly because of soil conditions or limited space. In many conditions there were not any other alternatives to dispose of the household waste. Seepage pits on average are 20ft to 30ft in depth.Below is an example how the system works:

The use of seepage pits was halted in October of 1991 in Jefferson County because of the concerns about polluting ground water.

The majority of homes have been taken off seepage pits as a result of upgrades to the Metropolitan Sewer District infrastructure over the past 40 years. After the residence was connected to the sanitary sewer, the seepage system (pit) was disconnected from the home and, in many cases, left in the ground. There are no regulations that require the homeowner to collapse the septic tank or seepage pit and fill them in with soil or rock, even though it is recommended by the Department of Public Health and Wellness. Many times the lids have become covered by grass and are unable to be seen. We recommend that you verify what type of system you had and be careful when walking around your property if you are unsure.

If you have concerns about your home having a seepage pit, you can contact the Department of Public Health and Wellness, at 574-6650, to see if we have records that indicate if you had a pit in the past and the location of the pit.

A Sewerage Treatment Plant (STP) is a facility designed to treat wastewater or sewage before it is discharged into the environment or reused. The primary purpose of an STP is to remove contaminants, pollutants, and pathogens from the sewage to ensure that the treated effluent does not harm the receiving water bodies or pose a risk to public health.

Here are the key components and processes typically found in a Sewerage Treatment Plant:

1. Inlet: The wastewater enters the STP through the inlet point, which is connected to the sewer network.

2. Preliminary Treatment: At the beginning of the treatment process, there are usually screening mechanisms that remove large debris, such as sticks, rags, and plastics. Grit chambers or sedimentation tanks are also present to allow the settlement of heavier particles like sand and grit.

3. Primary Treatment: The wastewater then flows into primary settling tanks or clarifiers, where the velocity is reduced to allow the settling of suspended solids. The settled solids form sludge at the bottom, while floating materials, such as oils and grease, are skimmed off the surface.

4. Aeration Tanks: The partially treated wastewater moves to aeration tanks, where it undergoes secondary treatment. These tanks contain microorganisms known as activated sludge, which consume organic matter and nutrients in the wastewater. Oxygen is supplied to the tanks to support the growth of aerobic bacteria.

5. Secondary Settling Tanks: After the aeration process, the wastewater and activated sludge mixture enters secondary settling tanks. Here, the activated sludge settles to the bottom as sludge, while the clarified water moves on to the next stage.

6. Tertiary Treatment (if applicable): In some STPs, additional treatment steps may be included for further purification of the wastewater. This can involve processes like filtration, disinfection (e.g., chlorination or UV treatment), or advanced techniques like membrane filtration or reverse osmosis.

7. Effluent Discharge or Reuse: The treated water, known as effluent, is discharged into a receiving water body (such as a river or ocean) if it meets the required quality standards. Alternatively, the treated water may be reused for non-potable purposes such as irrigation or industrial processes.

8. Sludge Treatment: The sludge collected from primary and secondary settling tanks is further treated to reduce its volume and stabilize it. This may involve processes like thickening, dewatering, digestion, or drying. The final treated sludge can be used as fertilizer, incinerated, or sent to a landfill depending on local regulations.

LEED BUILDING.
LEED stands for Leadership in Energy and Environmental Design. It is a green building certification program that was developed by the U.S. Green Building Council (USGBC) to encourage sustainable building practices and reduce the environmental impact of buildings.

The LEED program offers rating systems for various building types, including new construction, existing buildings, commercial interiors, and homes. Buildings are evaluated based on a range of criteria, including energy and water efficiency, indoor environmental quality, materials and resources, and sustainable site development.

LEED certification is a voluntary process, and building owners and developers can earn points by implementing sustainable design and construction practices. Buildings can earn one of four certification levels: Certified, Silver, Gold, or Platinum, based on the number of points earned.

LEED certification is widely recognized as a symbol of sustainability and is often used by building owners and developers to demonstrate their commitment to environmental responsibility. It is also used by governments and organizations as a requirement for new construction projects or as a benchmark for building sustainability.

The Earth's environment is the collection of all living and non-living things that exist on the planet. It includes the atmosphere, hydrosphere, lithosphere, and biosphere, which are all interconnected and affect each other in various ways.

The atmosphere is the layer of gases that surrounds the Earth, providing us with the air we breathe. It also plays a crucial role in regulating the planet's temperature and protecting us from harmful radiation from the sun. However, human activities like burning fossil fuels and deforestation have led to an increase in greenhouse gases like carbon dioxide, causing global warming and climate change.

The hydrosphere includes all the water on the Earth's surface, including oceans, rivers, lakes, and groundwater. Water is essential for all forms of life on the planet and plays a critical role in regulating the climate. However, human activities like pollution and overuse of water resources have led to a decline in water quality and availability in many parts of the world.

The lithosphere is the solid outer layer of the Earth, including the continents, ocean floors, and the upper part of the mantle. It provides the foundation for all life on the planet and is the source of many important resources like minerals and fossil fuels. However, human activities like mining and drilling for oil have led to environmental damage and the depletion of non-renewable resources.

Finally, the biosphere includes all living organisms on the planet, from microscopic bacteria to giant whales. It is a complex web of interdependent relationships that sustains life on Earth. However, human activities like deforestation and pollution have led to the loss of biodiversity and the extinction of many species.

Overall, the Earth's environment is a complex and fragile system that requires careful management to ensure its continued health and sustainability.
