Gregory Barr

Town of Annapolis Royal

285 St. George Street Box 310

Annapolis Royal, NS B0S 1A0

Dear Mr.Barr:

Subject: Annapolis Royal Water Reservoir Condition Assessment

This report summarizes the results of our review of the condition of the Lequille Water Reservoir located at

Civic Number 9661 Highway 8. In producing the report, we have reviewed ultrasonic thickness

measurement (UTM) reports provided by Huntley Sub-Aqua to determine the stability of the tank walls,

reviewed video reports of the dive operation to comment on the internal condition of the tank and performed

a ground level external visual inspection to comment on the external condition of the tank.

1. Background Information

Given the age of the tower, little background documentation was available to assess the current condition

against the original design and construction of the tower. The Town provided Hatch with the following

specifications:

Tank Diameter: 48 feet (14.63 metres) Tank Height: 32 feet (9.75 metres) Year of Construction: 1965 Capacity: 400,000 USG (1.5 M Litres)

No as-built information or original design records are available so the engineering analysis is concerned

with the current condition and steps to mitigate future tank degradation. Estimating past rate of corrosion

based on as-built conditions to extrapolate the lifespan of a “do nothing” option is not possible in the

absence of baseline condition and interim condition reports.

We also understand that there have been no reports of adverse water quality (turbidity, taste or odor) for

water coming from the reservoir.

July 12, 2016

H166873-CC-RPT-CIV-024-0001, Rev. APage 2


2. Reservoir Condition

The reservoir condition report has been divided into sections to address stability, interior, exterior, and base

of the structure.

2.1 Stability

The UTM was based on several hundred UTM points and a visual inspection report from Huntley’s Sub-

Aqua. The results of that investigation are presented in Table 1:

Table 1: Ultrasonic Thickness Measurements

Section Thickness Range (mm)

Comments (From Huntley’s Sub-Aqua)

1 Base 8.0 – 8.5 I did not find any metal deterioration on the interior or exterior. 2 Shell 6.5 – 6.7 I did not find any metal deterioration on the interior or exterior. 3 Shell 6.4 – 6.7 I did not find any metal deterioration on the interior or exterior.

4 Shell 6.6 – 6.9

Some minor seam deterioration on exterior welds to the top cap. I did not find any metal deterioration on interior or exterior walls.

5 Top Cap 4.9 – 5.1 Only 30 points were tested on this part of the reservoir

Based on the lowest reported shell thickness at maximum water depth, the structure has a factor of safety

against failure of the shell of 1.9. This factor of safety is based on conservative estimates of steel strength

and could be as high as 2.6 based on material commonly in use at the time of construction. There is no

apparent risk of failure based on the current thickness of steel.

2.2 Interior

From the video report, there did not appear to be any indication of major corrosion on the interior of the

tank wall. However, there was evidence of significant corrosion along one weld seam. Figure 1 shows a

representative section of this weld with pockets of corrosion. Figure 2 shows a close-up of the pitting on

and above the weld seam.

Figure 1: Weld Corrosion Figure 2: Pitting Close-Up

July 12, 2016



Pitting and corrosion appears to be limited to isolated areas along the tank wall and some welds. However,

the tank liner has degraded over the entire interior surface of the tank. Figure 3 shows the remains of the

tank liner (white) and the exposed metal (brown/black) at a representative section of tank wall.

Internal piping, shown in Figure 4, also appears to have lost liner material and may be showing signs of

corrosion.

Figure 3: Degraded Liner Figure 4: Potential Pipe Corrosion

2.3 Exterior

There were no obvious signs of corrosion or weld degradation on the exterior of the reservoir tank.

However, it is possible that corrosion is masked by the tank coating and may become evident later. The

label plate on the outside of the tank had become detached and there was significant rusting on its mount

plate, shown in Figure 5. The tank is founded on a concrete slab which was in good condition where visible.

The lip along the bottom of the tank was in relatively good condition except for one section on the

Figure 5: Label Plate Figure 6: Missing Sealant Figure 7: Corrosion Under Lip

west side of the tank. A significant section of foam insert was missing and the steel had begun to corrode.

Figures 6 and 7 show the corrosion along this section of the tank lip, which in the short term is not expected

to compromise tank functionality, but should be repaired to prevent further degradation.

July 12, 2016



2.4 Base

The base of the structure that forms the internal floor of the reservoir could not be assessed because of

sediment on the floor. We note that with this type of structure, failure of the lower section of tank would be

non-catastrophic and could be seen outside by leakage from the tank bottom. Since there is no leakage

there is no immediate concern with the lower section of tank. We have assumed that any rehabilitation

work would include spot repair and re-lining of the tank bottom.

3. Conclusions

Given the current condition of the tank and the lack evidence of water quality problems in the water supply,

there is no indication that the reservoir needs to be replaced at this time. However, because the lining has

degraded, the tank wall and internal piping is beginning to corrode. If allowed to continue, the reservoir will

likely need to be replaced in the short term. Without any baseline data to assess the progression of

corrosion, it is difficult to pinpoint a precise lifespan, but five to ten years is a conservative estimate.

Alternately, the tank may be drained, cleaned, and relined after spot repairs (grinding, plating and re-

welding) are done at the problem areas. This work is recommended as soon as possible to

a) Reduce the risk of corroded areas progressing beyond the point of repair;

b) Slow the rate of internal corrosion to extend the lifespan of the reservoir;

c) Prevent the risk of taste, odor and staining that can be related to rust in potable water;

d) Reinstate the lining is required to meet current standards for potable water reservoirs, and

e) Allow inspection of the tank bottom once cleaned.

When the interior work is done, we recommend stripping and recoating the exterior of the tank at the same

time to allow the exterior welds to be inspected and repaired in case there is corrosion currently hidden

beneath the existing coating. Exterior repairs should also include re-sealing the lower lip of the tank to

mitigate water ingress and slow corrosion, particularly in the section currently lacking the foam seal.

For capital planning purposes, preventative maintenance can be expected to extend the lifespan by twenty

years. We recommend that the tank interior, wall thickness and welds should be reassessed at the ten,

fifteen and twenty year mark to determine whether this lifespan estimate may be extended as a result of

the preventative maintenance.

4. Cost Estimates and Recommendations

The following analysis is based on a 2.0% inflation rate (based on the past 20 years’ average) and an

investment rate of 6.0% for a net discount rate of 4.0%. This discount rate has been used to calculate the

net present value of each option.

Based on current market costs, replacement of the tank would cost approximately $1,600,000. The

estimate includes a 20% cost contingency and an additional 15% in estimated engineering fees to cover

design and construction inspection.

Relining costs for the interior of the tank has been estimated at $180,000. Cleaning and re-coating of the

exterior of the tank with a urethane coating (20 year lifespan) has been estimated at $80,000. A contingency
