Yes he did. He created the tetrarcy (rule by four) whose purpose was to improve the deference of the vast frontiers of the Roman Empire, which were under constant attack. He appointed Maximian as his co-emperor. Maximian was in charge of the western part of the empire and Diocletian took charge of the eastern part. These two men were senior emperors (Augusti). The junior emperors (Caesars) subordinate to the Augusti were appointed. They were responsible for the most troubled frontier areas, the river Rhine in the west and the river Danube in the east.
Historians' views differ on this, because there were several divisions since the day of the emperor Augustus. But Diocletian is usually considered as the Emperor who in 285 AD set the division in motion that over time turned out to be the definite one.
Divided into four units, each with its own ruler.

Aqueducts did not affect the size of the Roman Empire as this was determined by other factors which were independent from them. They did contribute to prosperity as they supplied the towns with clean water and meet their level of demand. Water was used (and still is) both for cleaning and hygiene (which were important in the cities which were crowded and packed into city walls) and for manufacturing processes. Since the Roman Empire relied on and promoted trade, the urban economy was important.
Originally there were two tribunes elected, but by the end of the republic their number had grown to ten.
It was a very popular name up until the 1940s, and has since grown less popular.
The cereal grains, oats, rye, barley and wheat, were important. Root vegetables were grown and stored over winters. Fruit was grown and eaten fresh, dried, or made into wine or cider. Cabbage family plants were grown, as were peas and fava beans. Fresh greens, such as lettuce, were grown. Certain spices and seasonings were grown in Europe, most importantly mustard.
Diocletian divided the empire in order to make it more easy to manage. It had grown so large that it took weeks for messages and other communications to go from one end of the empire to the other. This was a serious issue regarding military and legal matters. By dividing the empire, it was thought that these problems would be eased.
Diocletian created the tetrarchy (rule by four), a co-emperorship with two senior emperors and two junior emperors, each in charge of one of new four large administrative units of the empire, the praetorian prefectures. He also decreased the size of the provinces of the empire and doubled their number to diminish the power of the provincial governors. He grouped them into 12 dioceses, whose heads, the vicars, were representatives of the emperor. The dioceses were an intermediate administrative layer between the provinces and the praetorian prefectures.
In A.D. 284, Diocletian became emperor. He believed that the empire had grown too large and too complex for one ruler to handle. In the most significant reform, he divided the empire into 2 halfs. One was named Greek-speaking east and the other Latin-speaking west. He took the eastern half for himself and appointed a co-ruler named General Maximian for the western half.

The Empire had become too large to control in a pre-mechanical transport and pre-electronic communications age. He split it into four parts, the two larger - east and west - ruled by their own emperor, the two lesser ones by a caesar. This gave each ruler a manageable area to control.
Any administration that grows is called an "Empire", not the other way round. Whatever it is, if it hasn't grown large, it's hardly an empire.
