IFALIK ATOLL

Rainwater Catchment and Storage Survey 2015

by Andrea Jalandoni, Blaž Miklavič, and Maria Kottermair,

with guides Callistus Hasefalgar and Mark Pekalimul

Methodology

The potential catchment area of every structure with a tin or concrete roof was surveyed in two of

the four villages on Ifalik Atoll, Rawaiu and Felaashigi. Due to time constraints, only catchments

with gutter and storage tanks were surveyed in the villages of Iyefangi and Iyeiuriu.

The potential catchment area (plan view) was calculated by measuring the dimensions of the roof

(length and width) with a laser distance meter (Tuirel T100). Two people performed the task, one

holding the laser meter, and the other holding or being the target, each of the two standing at the

opposite extremes of the measured dimension. The minimum and maximum distances between the

roof and the ground were measured by placing the laser meter on the ground and pointing the laser

to the measured roof extreme, or the way round if the roof extremes were low enough. The

displayed value was rounded to the nearest tenth of a meter (one decimal place). Since a couple of

accuracy tests showed that the measured distances tended to have a positive rather than a negative

error, the values ending with 5 at the second decimal place (e.g. 0.05 m) were rounded down rather

then up. The condition of the roof (usually tin) was noted. The actual catchment area was later

computed based on gutter length and roof configuration. The efficiency of the catchment was either

gauged in the field or computer from actual and potential roof area, although sometimes discounted

based on condition of gutter or roof.

The gutter coverage was thoroughly considered when measuring the catchment area, i.e. if the

gutter was shorter than the roof length, then the gutter length was recorded. The gutter inclination or

bulging that could affect the catchment was also considered and the dimensions measured

accordingly.

Every storage tank was measured and GPS locations and a picture was taken with a Trimble Juno 5

GPS unit. In many cases, additional pictures were taken with a GPS-enabled camera (Olympus

TG2). Two of the most commonly encountered storage tanks, here called Type A and Type C

(Figure 1), had their nominal volumes labeled. The volume of the other most common tank Type B

had a shape of a reversed truncated cone and its volume was calculated using the measured

dimensions: mid-perimeter (using a measuring tape), diameter, and height (both measured by the

laser meter). The same general approach was used for other encountered catchment tanks with

unknown volume. For smaller dimensions, a rigid metal measuring tape was sometimes used instead

2

of the laser meter, and a ruler was used to measure the distance of the tap from the bottom of the

tank.

The level of the water in the tanks at the time of visit in the three most commonly encountered tanks

was estimated by knocking on the tank in order to find the level at which the sound changes. Where

possible, the water level was observed from the top. Since this method gives more reliable estimates

it was also used to observe how the sound changes around the tank water level, which allowed to

learn how to use this change in knocking sound to find out the water level.

On Eauripik Atoll, only the locations of storage tanks along with a picture were recorded.

Preliminary Results and Observations

Observations

Please see attached map and spreadsheet.

Observations

• Even though most houses are traditional huts with thatched roof, many small structures likecooking or storage huts have tin roofs where rainwater is collected.

• Storage tanks provided by the government but also makeshift containers are very common

• People living next to a public structure like the church often put their storage tanks there; alsosome households with large roof areas have several storage tanks from the neighboring

compounds.

• Most community tanks are old and leaking, so they are not used anymore; the only one still inuse is at the school which was recently fixed (within the last few months).

Notes:

Roof Compound ID The order of the number generally reflects the order in which the features were recorded;

Potential Area Potential area in m2; typically EW*NS, unless adjusted

Actual Area Actual area in m2; computed based on gutter length and roof configuration

Efficiency(%) Either gauged in the field or computed from actual/potential. Sometimes discounted based on condition of gutter or roof.

Comment Material is always METAL unless specified here in comments

Gutter Coverage In percent of total possible coverage

Comment Material is always plastic

Storage ID Individual number comprised of Village, Compound ID, number, and “s” for storage

PhotoID Number of picture taken with GPS unit

NA not applicable

NR not recorded

Potential (m²)

W has gutter, E has gutter holders. E

gutter removed because trees

many cracks for overflow

Twisted and doesn't go all the way to

two more makeshift containers next to it, all full, gutter was bent but

Longitude/

Latitude

Longitude and latitude in WGS 194 coordinate system. All coordinates were recorded by Maria Kottermair using a Juno GPS unit. At the same time, one photo of each well was taken with the same unit. The only

exception is well F19-1w, whose coordinates were derived from data recorded by Qstarz GPS logger.
