TANK TESTING PROCEDURES

Section C

18

Testing Single-Wall Water Tanks

Important Warning For all TestsNever pressurize tank over 5 psig or 3 psig for 12’ diameter tanks

19

Testing Single-Wall Water Tanks

• Determine which test procedure is appropriate before you begin

• Air-Testable vs. Non Air-Testable tanks• Single-Wall Tank Air Tests are in

Sections D-1, D-2, D-3 (Pre Installation)• Water Test for Non Air-Testable Tank

is Section D-10 (Post Installation)• Follow each step of the instructions provided

in the Tank Installation Instructions INST 6001

20

Testing Air-Testable Tanks

• All air-testable tanks require a pre installation air/soap test

• All potable water tanks require a pre installation air/soap test

• Non air-testable tanks require a post installation test but not a pre installation test

Section C 21


• Connect a “Tank Test Manifold” to a primary fitting

• Use pressure gauge of 15 psig or less (max ¼ psig increments)

• Use pressure relief device to ensure tank pressure does not exceed 5psig (3 psig for 12’ tanks)

Tank Test Manifold(Contractor Supplied)

Section C 22


• Soap entire tank and inspect for air bubbles

• Soap all fittings and manways

• Contact CSI Field service immediately in the unlikely event a leak is discovered

Section C 23

PRE INSTALLATION AIR/SOAP TESTING PROCEDURES

Section D

24

Section D1 - Testing Single-Wall Tanks

Steps 1-3: follow Installation Instructions

4. Pressurize tank to 5 psig maximum (3 psig for 12’ tanks).

5. Monitor the pressure readings for 30 minutes for any loss in pressure from the initial reading which may indicate a leak.

6. While under pressure, cover tank outer surface including fittings and manways, with soap solution and inspect.

Steps 7-10 : follow Installation Instructions

25

EXCAVATION

Section E

26

Excavation Size

• Minimum spacing between tanks is 18” when no mechanical anchoring is required

• Tank spacing depends on soil in the excavation as well as the choice of anchoring systems

27

Excavation Size – Stable

• Minimum spacing between tanks and excavation walls, in stable soils

28

Excavation Size – Unstable

• Minimum spacing between tanks and excavation walls, in unstable soils

29

Excavation Size

When job site conditions require an oversized hole, fill the entire

excavation with approved backfill.

30

GEOTEXTILE FABRIC

Section F

31

Geotextile Fabric (Filter Fabric)

Geotextile fabric is required between backfill and native soils for certain installations such as unstable soils, swampy areas and landfills to prevent backfill from migrating and thereby undermining support of

the tank, piping or paving.

32

Geotextile Fabric (Filter Fabric)

• Geotextile fabric should be used in tidal conditions, area of frequently changing ground water, and unstable soils

• Do not use plastic, or any other material that may tear or degrade, as a replacement for geotextile fabric

33

BURIAL DEPTH

Section G

34

Burial Depth and Cover

• Minimum bedding under tank is 12” (18” in a wet hole) and a maximum of 24”

• Maximum standard burial depth is 7’• Traffic pad must extend at least 12”

beyond tank perimeter• Minimum burial depth will vary

according to job site conditions:– Traffic load– Mechanical anchoring– Number of tank sumps/risers

35

Burial Depth – No Traffic Load

• For No Traffic Loads:– 4’-10’ tanks need a

minimum of 24” backfill or 12” backfill and 4” reinforced concrete

– 12’ tanks need 42” backfill or 38” backfill and 4” reinforced concrete

36

Burial Depth – Traffic Load

• For Traffic Loads:– 4’-10’ tanks need a

minimum of 36” backfill or 18” backfill and 6” reinforced concrete

– 12’ tanks need 48” backfill or 36” backfill and 6” reinforced concrete

37

TANK ANCHORING

Section H

38

Tank Anchoring

The three common methods are:1. Deadmen Anchors2. Concrete Anchor Pad3. Overburden (no mechanical anchoring)

For minimum burial depths refer to the Anchoring Chart in Installation Instructions INST 6001 (Appendix A)

39

Mechanical Tank Anchoring

• If water can enter the tank excavation, CSI recommends mechanical anchoring

• Use only CSI fiberglass anchor straps

• Deadmen or concrete anchor pads may be used

• After installation, all exposed metal should be coated or galvanized to protect against corrosion

40

Tank Anchoring – Anchor Straps

For All Mechanical Anchoring:• Use correct length anchor

straps for each diametertank

• Anchor points must be aligned with designated anchor ribs (±1"). ►◄Do not use straps between ribs except on 4' tanks

• Use one anchor point per strap end

41

Tank Anchoring – Anchor Straps

• Anchor straps on fiberglass tanks:– Must have anchor points at the

bottom of the hole aligned within 1”

of the designated rib– Should be tightened with

turnbuckles (seen here) or come-alongs to give a “snug” fit

– Are available in a convenient man-out-of-hole split strap option

42

Using Deadmen:• Ensure lifting equipment is rated to handle the full

load before lifting• Use a minimum of 2 equally spaced anchor points

Tank Anchoring - Deadmen

43

Tank Anchoring - Deadmen

• Lay the deadmen in the excavation parallel to the tank and outside of the tank shadow

• Each tank requires its own deadman on both sides, or if one deadman is used between adjacent tanks, it must be doubled in width

• Place multiple deadmen, in contact, end to end

44

Standard installation is bottom of deadman even

with bottom of tank

Tank Anchoring – Anchor Pad

Using Anchor Pad:• As a minimum the anchor

pad for stable excavations must be at least 8" thick, with #6 rebar on 12" centers each way

• When a concrete anchor pad is used the tank and pad must be separated by at least 12” of approved pea gravel or crushed stone backfill

• Embedded anchor points must be designed for the working loads in Section H of the Installation Instructions

45

VERTICAL DIAMETER MEASUREMENTS

Section I

46

Vertical Diameter Measurements

• Excessive Deflection (loss of vertical diameter) of any installed tank can create stress on the tank

• The major cause of deflection is the loss of tank support because of improper backfill material or installation method

• Compare all deflection measurements to the limits established by CSI on the Tank Installation Checklist

• There are 5 total vertical diameter measurements

Refer to Section I – Installation for detailed measurements

47


• “First Vertical Diameter Measurement”– After placement of tank

on backfill bed

• All measurements are recorded on the Tank Installation Checklist

48


• “Second Vertical Diameter Measurement”– When mechanical anchoring

is completed– (only applicable if

mechanical anchoringis used)


49


• “Third Vertical Diameter Measurement”– After backfill is to tank top


50


• “Fourth Vertical Diameter Measurement”– When backfill is to subgrade,

but BEFORE the concrete pad


51

• “Fifth Vertical Diameter Measurement”– When backfill is to

subgrade, but BEFORE the concrete pad

• Complete Tank Installation Checklist

TANK INSTALLATION PROCEDURES

53

Installation Procedures

Basic Installation Steps Overview:

1. Review all instructions and make sure you are compliant with proper procedures

2. Add Backfill Bed

3. Place Tanks in excavation on Backfill bed

4. Take First Vertical Diameter Measurement

5. Complete Mechanical Anchoring

6. Take Second Vertical Diameter Measurement

7. Backfill Tank to tank top

8. Take Third Vertical Diameter Measurement

9. Backfill to subgrade

10. Take Fourth and Fifth Vertical Diameter Measurements

54

Installation Procedure – DRY HOLE

• Minimum initial tank bed of 12” of approved backfill

• Probe first 12” lift under tank between 5 and 7 o’clock positions of tank

• Probe second 12” lift (most critical area)

55


• Use long-handled probes to eliminate voids (keep employees out of the hole)

56


• Ballast tank only AFTER backfill is to top of tank

• In stable soil conditions the recommended clearance for tanks 4’-10’ in diameter is 18” between adjacent tanks

57

Installation Procedure – WET HOLE

• De-water hole as much as possible

• Place 18”- 24” backfill bed under tank

• Use only enough water ballast in tank to sink tank

• Keep tank vented to prevent pressurization• Ballast level inside tank should not be more than

12” above ground water level outside of tank

58

Installation Procedure – WET HOLE

Fiberglass tanks installed in unstable soils such as peat,

swamp or landfill type must have a hole size big enough to allow a minimum space equal to half the tank diameter from the ends and

sides of the tank to the excavation walls.

59

Internal Piping Clearances

• Internal piping should be a minimum 4” from bottom of tank (6” min. 12’ tanks)

60

Manways – Manway Extensions

• DO NOT enter tank!!• DO NOT exceed 50 ft-lbs when tightening

manway bolts

61

POST INSTALLATION TANK TESTING PROCEDURES

62

Typical Water Tank Testing

• All potable water tanks must be air/soap tested in accordance with Section D-1 of the Tank Installation Instructions INST 6001.

• Most non-potable tanks are not air testable and thus require a different test.

63

Typical Water Tank Testing

• For this training we will focus on Section D-10, referencing from the Tank Installation Instructions booklet INST 6001

• D-10: WATER TEST FOR A NON AIR-TESTABLE TANK (NON PETROLEUM TANKS)

64

D-10 Water Test Procedures

1. Comply with the requirements of Section C.2. Tanks may only be water tested if the backfill is

at tank top (see Figure D10-1).

65


3. Expose tank penetrations on tank top by temporarily removing backfill.

4. So water does not exit the inlet/outlet pipe, install a turned up elbow or plug.

5. Completely fill the tank with water to a level 2" into the access collar(s).

Fill tank with water to a level 2” into the access collar(s)

Flowtite® Water Tank

66


6. Wait at least 30 minutes, if the water level in the collar does not drop more than ¼", the tank is considered acceptable and leak free.

7. If the level drops more than the ¼", ensure that inlet and outlet pipe caps or plugs and collars are not leaking, then refill the tank and retest.

8. After the tank is proven to be watertight, remove the water in the tank to below the pipe invert.
