    Incorrect. The correct answer is highlighed in green below.

    A 4 bedroom house using an aerobic treatment system must have a minimum rated treatment capacity of ___________ gallons.
    1. 400
    2. 750
    3. 500
      (905.100-d) Sizing. Aerobic treatment plants that are listed by NSF or a laboratory approved by ANSI to determine compliance with ANSI/NSF Standard 40 as Class I and rated at 500 gallons per day will be allowed for the treatment of sewage from residential property having up to and including 4 bedrooms. Other aerobic treatment plants that are listed by NSF or a laboratory approved by ANSI to determine compliance with ANSI/NSF Standard 40 as Class I shall be sized as follows: 4 - 500
    4. 1000
  4. Section 905.100 — Aerobic Treatment Plants
    Incorrect. The correct answer is highlighed in green below.

    Standard 40 states an initial service policy requires:

    2. A 2 year service policy be furnished to the contractor
    3. A lifetime service policy be furnished to the purchaser
    4. A 2 year service policy be furnished to the purchaser
      (905.100-g-1) Initial service policy: A 2-year policy shall be furnished to the purchaser by the private sewage disposal installation contractor through the manufacturer or the distributor of the aerobic treatment unit.
  5. Section 905.100 — Aerobic Treatment Plants
    Incorrect. The correct answer is highlighed in green below.

    In the event of an electrical or mechanical failure, an aerobic treatment plant must:
    1. Allow less than 100 gallons of non-treated effluent to discharge.
    2. Allow less than 50 gallons of non-treated effluent to discharge.
    3. Be attached to an alternate power source.
    4. Prevent the discharge of wastewater from any opening not part of the designed path.
      (905.100-h) Aerobic treatment plants shall produce an effluent meeting the physical, chemical and biological requirements of Section 905.110. Under normal operation and in the event of an electrical or mechanical failure or other performance failure or malfunction, the design and construction of the aerobic treatment plant shall prevent the discharge of wastewater from any opening that is not part of the designed flow path of the entire treatment process and shall prevent the discharge of wastewater that is not in compliance with Section 905.110.
  6. Section 905.100 — Aerobic Treatment Plants
    Incorrect. The correct answer is highlighed in green below.

    To be considered for use on a non-residential property, one requirement may be:
    1. Installation of a flow equalization device.
      (905.100-j-3) Hourly flows from the wastewater source into the plant are less than or equal to the treatment capacity of the plant divided by 24. This may require the installation of a flow equalization device.
    2. A peat filter preceeding the aerobic treatment system.
    3. Total daily flows from the wastewater source into the plant are at least 50% of the rated hydraulic capacity.
    4. Wastewater influent shall exceed design specifications for BOD5 loading.
