City of Kramer Lagoons
The City of Kramer manages three sewage lagoons which must be periodically inspected by city officials. Any items noted in the inspection require the city to repair, replace or mitigate further issues until they can be repaired. At an absolute minimum, the city council should plan an expenditure of four hundred ($400.00) in the budget, which will be for mowing and chemical maintenance of algae and reeds about the perimeter.
The sewage lagoon inspection is outlined below.
1. Lagoon Structure and Condition:
- Access to the site: Check the road to the lagoons for accessibility by the city, inspectors, and work crews should repair be required. The area immediately surrounding the lagoons should be mower periodically to manage pests and aid in the inspection for erosion and slumping.
- Site Perimeter: The site must be enclosed by the three (3) strand twelve (12) gauge barbed wire, have lagoon warning signs about the perimeter and a secured access gate.
- Liner Integrity: Check for cracks, tears, or damage to the lagoon liner (clay or synthetic).
-
Erosion and Slumping: Look for signs of erosion on the banks and slopes of the lagoon, as well as slumping or settling of the soil.
-
Vegetation: Ensure that vegetation, especially trees and bushes, is not too close to the lagoon and that it doesn't obstruct sunlight or airflow.
-
Animal Burrows: Check for evidence of animal burrowing (rodents, etc.) in the dikes and banks, as this can compromise structural integrity.
-
Inlet and Outlet Structures: Inspect inlet and outlet pipes, baffles, and other structures for damage, blockages, or leaks.
-
Safety: Ensure the availability and condition of personal protective equipment, railings, walkways, and emergency flotation devices.
2. Water Quality and Treatment:
-
Odor: Observe for unusual or offensive odors, which could indicate treatment issues or excessive sludge.
-
Scum and Floating Sludge: Look for excessive scum or floating sludge on the surface of the lagoon.
-
Foam: Check for excessive foam, which could be a sign of treatment problems or the presence of certain chemicals.
-
Discoloration and Sheen: Note any unusual discoloration of the water or the presence of a sheen on the surface, which could indicate pollution.
-
Vegetation Growth: Monitor for excessive growth of algae or other vegetation within the lagoon, as it can impact treatment efficiency.
-
Pest Infestations: Look for evidence of insect infestations (e.g., midge flies) or other pest problems.
-
Sludge Depth: Measure sludge depth in the lagoon to determine if de-sludging is needed, according to the EPA.
-
Sampling: Collect and analyze grab samples of influent and effluent to monitor BOD, TSS, ammonia, and other relevant parameters.
3. Monitoring and Reporting:
-
Discharge Monitoring: Ensure that any discharges from the lagoon are monitored and reported according to regulations.
-
Compliance: Verify that the lagoon system is operating in compliance with all applicable North Dakota State Water Quality Standards and other relevant regulations.
-
Documentation: Maintain accurate records of inspections, sampling results, and any maintenance or repairs performed.
4. Seasonal Considerations:
-
Winter Preparation: In the fall, take steps to prepare the lagoon for winter, such as ensuring proper water depth and minimizing ice formation.
-
Spring Startup: In the spring, check for any damage or issues caused by winter weather and ensure the system is operating properly.
By following this checklist and performing regular inspections, you can help ensure that your sewage lagoon is operating effectively, minimizing environmental impacts, and complying with all applicable
