Para 2 ; Under the system of Irrigation generally followed
In gardens In Bahrain two channels are dug on different 1
levels and these channels serve different purposes. The
channel on the higher level, known as ^Sab' 1 ^ ± s the
irrigation channel proper and carries water from the
storage tank (which is fed \yy the tube^to all parts of
the garden. The channel on the lower level, known as

"Manajjar", removes seepage I.e. carries away the brackish
water which oozes out of the saturated soil. This water
is highly saline and cannot be utilised again for irrigation.
I understand that if these secondary drainage channels are
not dug irrigated land soon becomes too saturated with
salt to be productive.
Water which flows into the sea from these seepage
channels is not wasted as, when it flows into the sea,
it has performed its function of irrigation and is carrying
away deleterious salt. Wastage does occur, however,
when gardeners fail to close the valve on the tube which
feeds the tank when the tank is already full. When this
happens water overflows from the tank and is drained away
into the sea without being utilised.
Para 3 : The information which I have secured about wells
at Qatif is from Dr. Bramkamp, Head Geologist of CASOC.
He informs me that only two drillers, employees of the
Qosaibis and Kanoos respectively, are working in or near
Qatif. One driller cannot complete a well in less than
5 or 6 weeks. The maximum rate at which wells are being
drilled is therefore 4 per quarter. Dr. Bramkamp Informed
me that in the coastal area ten miles south of Qatif to
ten miles north of Qatif there are not more than 25 to 30
drilled wells. The volume of the good wells ranges from
5,000 barrels per day to 15,000 barrels per day assuming
that the flow is continuous. (1 barrel » 42 gallons).
Most of the wells have valves.
