Made from 150mm wide x 4mm thick lightweight glass reinforced plastic (GRP) they offer higher durability and longer life than products made from cast iron or other metals.
They are provided with red datum numerals for easy surveying and the numerals can either be on separate boards or printed directly onto the board itself.
Fixings are made by eight M10 stainless steel screws into the pre-drilled holes on the board.
Special ranges or sizes can be produced to meet specific project requirements.
The Baish Dam is a gravity dam on Wadi Baish about 35km northeast of Baish in the Jizan Region of south-western Saudi Arabia.
The dam has many purposes including flood control, irrigation and groundwater recharge. The total reservoir capacity of the dam is 192 million m3.
The dam was constructed between 2003 and 2009 and at 106m high on completion, it was the tallest dam in Saudi Arabia. It is owned and operated by the Ministry of Water and Electricity.
Baish dam is one of six dams currently undergoing the change from a manual to a fully-automated monitoring system.
The original instrumentation equipment was installed during construction and was entirely manually-read. The Ministry made the decision to upgrade the instrumentation to a modern automatic system including full data logging of all instruments together with alarm trigger levels and data access via the Internet.
