Nebraska Administrative Code › Topic - ENVIRONMENT AND ENERGY › Title 123 - NEBRASKA DEPARTMENT OF ENVIRONMENTAL QUALITY › Chapter 5 - DESIGN STANDARDS AND SPECIFICATIONS › Section 123-5-004 - Force Mains

Current through June 17, 2024
004.01 Force mains
  will be sized so that a cleaning velocity of at least 2.0 feet per second is
  achieved at the minimum pumping rate of the lift station.
004.02 The minimum diameter of force mains
  transporting raw domestic wastewater will be four inches.
004.03 Force mains will be designed with air
  relief valves located at high points in the force main. Vacuum relief valves
  may be required where an evaluation of the design indicates they are
  needed.
004.04 Force mains
  discharging into manholes will enter the manhole no more than two feet above
  the gravity flow line.
004.05 Force
  mains and all installed valves and appurtenances will be designed to withstand
  the pumping shutoff head pressure. Force mains will be pressure tested equal to
  water mains.
004.06 Force mains
  will maintain the same separation distances to water mains and wells required
  for gravity sewers. See Chapter 5, 002.08 - 002.10.
004.07 Wastewater pumps will be selected that
  operate effectively over the range of head loss conditions that will exist over
  the life of the system. Piping system head capacity curves will be prepared for
  both the new pipe condition using the appropriate coefficient of roughness and
  for the aged pipe condition that will result after years of service. For the
  aged condition, a Hazen Williams "C" value not higher than 120 will be used for
  polyvinyl chloride (PVC), polyethylene or lined ductile iron, and for unlined
  iron or steel pipe a "C" value no higher than 100 will be used.
Nebraska Administrative Code › Topic - ENVIRONMENT AND ENERGY › Title 123 - NEBRASKA DEPARTMENT OF ENVIRONMENTAL QUALITY › Chapter 5 - DESIGN STANDARDS AND SPECIFICATIONS › Section 123-5-005 - Wastewater Lagoons

Current through June 17, 2024
005.01 The seepage
  rate of wastewater lagoons will not exceed one-eighth inch per day at the
  design maximum water depth. A lower seepage rate, or zero seepage, will be
  required if the Department determines that additional ground water protection
  is required. Ground water monitoring wells will be required where the
  Department determines that monitoring is necessary.
005.02 The liners of wastewater lagoons will
  be tested prior to the lagoon being placed into service. The test results will
  be submitted to the Department for review. Synthetic liners will be tested
  according to the manufacturer's instructions or other tests required by the
  Department. Soil liners will have the seepage rate measured by one of the
  following tests:
005.02A An independent soils
  testing laboratory will determine the coefficient of permeability from
  undisturbed core samples taken from the liner. The seepage velocity will be
  calculated using Darcy's Law at the design maximum water depth. Each
  permeability test swill pass the seepage test. Areas that do not pass will be
  reworked and retested. The minimum number of core samples thatwill be tested is
  listed in the following table.

005.02B The
  seepage rate will be tested directly by filling the cell with water and
  measuring the change of water level over time. The test will run at least 21
  days. A control device must be used to measure the effects of rainfall and
  evaporation during the test. If the water depth during the test is less than
  the design depth, the test result will be adjusted to calculate the seepage
  rate at the design water depth of the cell. This test will be conducted under
  the supervision of a professional engineer.
005.02C Wastewater lagoons with a water
  surface area less than one acre may use a two-barrel test. One barrel, without
  a bottom, will measure the seepage rate and the other barrel, with a solid
  bottom, will be used as a reference to account for rainfall and evaporation. A
  professional engineer will supervise this test and verify the results.
005.02D Another method approved by
  the Department.

  effluent flow measurement. Lift station elapsed time meters will satisfy this
  requirement.

  to provide primary treatment for vegetated submerged bed constructed wetlands
  unless a reliable means to remove algae is provided.
008.02 Multiple constructed wetland cells
  will be provided if the design flow is 5000 gallons per day or greater. Bypass
  structures will be included to allow each ceil to be isolated.
008.03 Constructed wetland systems will be
  designed to prevent storm water runoff from entering any part of the wastewater
  works, unless specifically designed to treat runoff.
008.04 Constructed wetland cells that treat
  domestic strength wastewater will have seepage rates no greater than one-eighth
  inch per day. Liners for constructed wetlands cells that treat higher strength
  wastewater will meet the seepage rate specified by the Department for the
  specific waste.
008.05 The bottom
  of the soil liner will be at least four feet above the seasonal high ground
  water level.
008.06 Effluent
  structures will be equipped with water level control devices capable of
  controlling the water depth in the wetland cell anywhere from the maximum
  design level to the bottom of the cell.

  may be laid above the media to aid in plant rooting, and
008.07B One-inch to three-inch cobbles may be
  installed at the influent and effluent ends to assist in flow distribution and
  collection.
