Dear Mr. Belgrave,
"bv
Zellaq Water Supply
Attached is a study of the ^ellaq Water Supply
compiled by our Petroleum iSngineers.
Several times in the past you have asked for
information on this subject and v;e are herewith submitting
a review of the water situation on the Zellaq side of
Bahrain Island.
Would appreciate any comments you may have
regarding the possibility of reducing the loss of irrigation
water to the sea as,in course of time,indiscriminate use will
affect not only the company's supply of domestic water but
also the Sheikhs' supply for irrigation.
Yours very truly,
The Bahrain Petroleum Company Limited

Chief Local Representative.

Zellao Water Supnly N ,W
The satic head in the water producing zones which
are the main source of dome^stic water supply for .the Inland
has been decreasing for a number of years. For details o f this
decrease please refer to i-r. G.W. Gulmon's report entitled
"Water Resources of Bahrain" dated May 12,1941. In particul.,^
the static head in the vicinity of Zellaq has shown a marked
dedrease, and it has been tiaarr recently unofficially brought
to our notice that^ the owners of the gatdens whose wells have
been affected attrifyite the consequent reduction in water
production to the fact that the Company obtain water for field
and domestic use from wells sunk in this area.
Although we do not contend that prodjction of water
for Company use will in no way affect other wells producing
from the same source, we believe that the volume of water
involved is so small in comparison with the large volume pro
duced ,for irrigation purposes in the same area that its in
fluence on the static head would be almost negligible.
In the narrow strip of coast line extending for
approximately two miles notth to approximately two miles south
of Zellaq^there are more than 40 wells, many vjf which are not
even provided witha control gate. The water produced by
these wells is estimated at approximately half a million barrels
per day, a large percentage of which flows into the sea from
drainage ditches.
■ order to ascertain the volume of water runnin?"
into the sea, a survey was conducted November 2 and 3,194l"
along the coast line under discussion and the actual flow of
water m the drainage ditches was measured. The datet obtained
is attacned m tabulated summary and detailed form and the
looations of the ditches referred to in the tabu-
' dr ' e snown on the accompanying sketch ma-o.
