The Avaza national tourist zone is one example of promising, ongoing economic projects. In Avaza, the new water treatment facility with a capacity of 11.9 million m3 per year has been put into operation to offer uninterrupted clean drinking water to citizens and guests of the town. The water supply system has also been rehabilitated in Turkmenbashy, where several new pumping stations, drinking water reservoirs and thousand of metres of new pipelines were installed. It is an important tool for ensuring uniformity and standardization of environmental standards with regard to economic activities in the Caspian Sea area. Issues such as emergency response management, protection of nature reserves and biological diversity are addressed through the Tehran Convention, and are essential considerations for oil and gas companies operating in the area.
