Being located in a dry region, Iran has always been dealing with the water crisis. The threat, however, made the country to develop its water and sewage industry so that now Iran can produce the majority of needed equipment and has to import only a share of less than 10% that are not economical to be produced.
As we discussed in Water and Sewage Infrastructure section, both water distribution and sewage collection networks are not developed throughout the country, so high-tech purification and filtering equipment are not the priority in the industry to spend large sums on importing them.
In other words, the country now needs to complete its water distribution and sewage collection networks utilizing pipe and thereof which are provided entirely by local producers rather than equipping the incomplete cycles with modern instrumentation and controlling systems.
However, since the country is in a severe water stress, it has to start recycling water and sewage and therefore importing filtering and purifying machinery, parts, etc. are inevitable.
Regardless of all the advancements in engineering and producing all kinds of pumps, pipes, valves, fittings, etc. needed for establishing water distribution network, the country has to spend money on importing those items, which are not economical to be produced in the country. Then supplying items like distilling or rectifying plants, filtering & purification systems, centrifuges, parts thereof, etc. to this market could be the best opportunity for international providers of these items to have a share in this growing and profitable market.
