Turkey is composed of 25 main river basins, each with its own hydrological character, climate sensitivity and socio-economic pressure. Treating drinking water, irrigation, wastewater and energy decisions independently inevitably produces contradictory outcomes on a ten-year scale.
The basin-based approach evaluates these decisions inside a single water budget. When rainfall-runoff modeling, sector demand curves and climate scenarios sit on the same table, engineering design ceases to be a downstream activity and becomes an instrument that guides investment.
The field experience TÜMAŞ has gathered across dam, potable water and wastewater projects shows that basin-scale planning is now a national necessity. Positioning this approach at the start of design costs far less than the corrective work it spares us later.
