Water transmission

Transportation of water from storage facilities to distribution networks takes place through water transmission pipelines. The pressure is created either through gravity or associated pumping stations. The water is channeled from the source, such as a reservoir, to water treatment plants which is then pumped into service reservoirs and distribution networks, and finally arriving at private homes and companies.

For water transmission pipelines, commonly used are concrete pipes, ductile iron pipes, steel pipes or GRP/GRE pipes. For pipelines in smaller dimensions plastic pipes such as HDPE may be used.

There are various reasons related to history and design why individual authorities and consulting engineers may prefer different valve types and designs. Some designers prefer gate valves, others butterfly valves – and within each valve category, several design options are available. The choice of valve may depend on project specific applications as well as availability of different pressure classes. For water transmission, AVK offers a vast range of gate valves, centric and double eccentric butterfly valves, air valves and swing check valves as well as couplings, repair clamps and valve accessories.
