Water transmission

When transported from storage facility to distribution networks, water is travelling through transmission pipelines. Here, the necessary pressure is created either through gravity or through associated pumping stations. Water is channelled from its source, such as a reservoir, to a water treatment plant. From here, it is usually pumped into service reservoirs and distribution networks, finally arriving at private homes or facilities.

For pipelines to water transmission, concrete, ductile iron, steel or GRP/GRE are often the preferred materials. For smaller dimensions, plastic pipes such as HDPE can be used.

There are various historical and design-related reasons why individual authorities and consulting engineers prefer different valve types and designs. While some are comfortable with gate valves, others prefer butterfly valves – and within each valve category, several design options are available. The choice of valve will also depend on project specific applications as well as availability of different pressure classes. For water transmission projects, AVK offers a broad range of gate valves, centric and double eccentric butterfly valves, air valves, swing check valves, mechanival and SCADA control valve,eccentric plug valve  and a wide selection of couplings, repair clamps and valve accessories.
