The following is a list of major physical components that are checked during an inspection (this list contains the most basic components and may vary from system to system):


Maximum Day Design Capacity

  • This number, reported as gallons per day (gpd), is calculated from water treatment plant component specifications.

  • For example, a well pump of 25 gallons per minute operating under normal conditions can provide a maximum-day design capacity of 18,000 gpd.


Generator (if applicable)

  • Community water systems with at least 150 service connections and/or a population of 350 or more are required to have standby power.

  • The generator should have automatic switchover and should be able to satisfy the average daily demand of the water system.

  • Where standby power is required, an audio-visual alarm indicating a loss of standby power is required.



  • Well pad:

    • Must be concrete and 6' x 6' x 4',

    • Must be kept free of algae, debris, and plant growth, Should not have any cracks.

  • Set-back distances:

    • Well should be at least 100 feet from any septic, reclaimed, or waste water lines.

    • Well should be at least 100 feet from any high risk hazard and at least 50 feet from any low risk hazard. [Rule 62-555.312]

  • Well casing:

    • Should be 12 inches above grade,

    • Should be free of corrosion.

  • Sanitary seal:

    • Should be smooth-nosed and downward opening,

    • Should be located upstream of the check valve.

  • Check valve:

    • Should be functional with no visible signs of leaks,

    • Should be located downstream of the raw water sample tap and upstream of the chemical injection point.

  • Security:

    • Wells must be enclosed in housing or fences with lockable access gates.

  • Well vent protection:

    • If a well vent is present, it must be screened with number 24 mesh to prevent insects and other contaminants from entering the well.

    • If a well vent is not present, at the time of any structural or equipment changes to the well or well pump, a well vent shall be provided.


Flow Meter

  • Required for all systems that submit Monthly Operation Reports (MORs).

  • Should be calibrated in accordance with the manufacturer's specifications.




  • Chemical delivery pumps:

  • Should be functional and free of corrosion.

  • Chemical injection points:

  • Should be free of leaks and corrosion.



Aeration (if applicable)

  • Overall condition.

  • Protective screen condition:

  • Should be number 24 mesh screen that is intact.

  • Algae growth :

  • There should not be any visible algae growth in or around the aerator.



  • General tank condition:

  • Should be free of corrosion,

  • Should be structurally sound,

  • Should be enclosed by a fence with a lockable access gate.

  • Specific tank components (if applicable):

  • Site glass should be in good condition,

  • Relief valves should be functional and protected with number 24 mesh screen,

  • Pressure gauge should be functional and legible.


High Service Pumps

  • General condition:
