Flow Plans, Schematics, etc.)

MORs, Sampling Data Submittals DEP Notices, Correspondence, etc.

Paper Work (part 2…) Uni- Directional Flushing Program Pump Specifications Valve Maintenance / Exercising Plan Tank Inspection Report

Signed, Sealed by a P.E. Within Last 5 Years

Auxiliary Power Plan Emergency Response Plan (ERP)

04/11/235

Annual Flow Data

Flows rates determine if appropriate pumping capacity, storage capacity and auxiliary power requirements are being met.

04/11/23 6

O & M Log BooksLog books must be maintained at the treatment plant and current to the most recent visit.

04/11/23 7

Wells

Housekeeping

Needed

All wells should be equipped with a well casing vent. In cases with no vent the disinfection port may be converted to act as a vent.

04/11/23 8

Flow Meters

Flow meters must be checked periodically for accuracy.

04/11/23 9

Piping• All piping must be screened (especially dump lines, overflow pipes, vents, etc.) and , labeled & color-coded (ex.: reuse = purple).

04/11/23 10

Lime Hoppers

Lime hoppers should be covered. The rooms should be kept clean. A ventilating fan is recommended.

04/11/23 11

Additives/Lubricants

Oil -lubed pumps must utilize food grade oils.

NSF Standard 60 Approved (or equivalent).

Hypo chlorination systems must use NSF 60 approved chlorine.

04/11/23 12

Maintenance

Clean, well- maintained facilities let the inspector know you share their dedication to providing safe drinking water.

04/11/23 13

Safety Be sure sources of contamination are not stored in close proximity to wells.

04/11/23 14

Safety

Prevent unauthorized entry. Consider fences, locked doors, gates, alarms, etc.

Open windows at a well house encourage unwanted visitors.

04/11/23 15

Safety

If fencing is not an option, other forms of well protection are available.

04/11/23 16

Safety Devices

SCBA* is required at all Gas Chlorination Facilities.

…MUST be inspected often (according to NIOSH guidelines).

04/11/23 17

Chlorine Rooms

Chlorine rooms must be designed to meet

Ten State Standards

04/11/23 18

Chlorine Rooms

Open drains in gas chlorine rooms are not acceptable (why not?).

04/11/23 19

Chlorine Rooms

All gas cylinders should be properly secured to a wall…

And kept out of direct sunlight.

04/11/23 20

Chlorine Rooms Hypochlorination

tanks must meet with ANSI / NSF 60 standards.

All openings must be protected and the tank kept out of direct sunlight.

04/11/23 21

Chlorine Rooms Exhaust vents

must not discharge near entrances.

Chlorine vents must be low …preferably as far as possible from entrances.

Chlorine Rooms

04/11/23 22

Plants Labeling of all

equipment and piping gets extra points from the inspector.

Operating Pressures and chemical feed rates will be noted.

04/11/23 23

Alarms Chlorine alarms must be

fully operational at all times;

Must be tested frequently to insure proper working condition.

04/11/23 24

Elevated Storage Tanks

Overflows should be brought down to 12” to 24” above ground level

Discharge should be to a splash plate

04/11/23 25

Elevated Storage Tanks

Storage tanks with elevated overflow outlets must have both a flapper valve and a screen.

04/11/23 26

Elevated Storage Tanks

Some systems become creative in meeting certain requirements. This may not work as well as intended.

04/11/23 27

Storage Tanks All vents must be

properly screened to help prevent contamination.

Tanks should be kept in good condition w/a proper pressure release valve.

04/11/23 28

Concerns noted on Report:

“DEFICIENCY 1: Storage tank protectionPipe inlet openings should be sealed from rainwater. 

RULE REFERENCE: 62‑555.330(3) RECOMMENDED ACTION: Refer to

Ten State Standards: finished water structures shall have suitable watertight roofs which exclude birds, animals, insects, and excessive dust.Please correct by August 31, 2011.”

Site Review

Surrounding areas are noted for possible sources of contamination.

04/11/23 30

TestingChlorine and pH readings will be conducted during the survey. Proper testing equipment must be on-hand and properly maintained.
