They saw water as both a physical and spiritual phenomenon. They considered their great civilization as something that arises from water.
The Incamisana temple at Ollantaytambo in Peru was constructed for worship of deities who gave the Inca people water and water itself. Even today in our modern terms, the structure represents the Inca’s masterpiece of both civil engineering and construction. It was designed to focus on religious ceremonies and offerings.
It’s definitely a truly remarkable achievement especially, if we consider the region’s harsh weather and the altitude of 2,792 m (9,160 ft) above sea level.
Flooding that took place in 1679 damaged the temple, but the deposit of sediment fortunately preserved the lower portion of it.
The Patacancha Valley is divided into four main basins (the Yuracmayo, San Pablo, Paq'chapata and Puma Paqcha (or Media Luna). Through these basins, the Inca engineers were able to redesign a canal system extending it for several kilometers.
Many of the channels in the system were originally built by the settlers of Killke (Quillke), pre-Inca culture (900 to 1200 AD). These people occupied the South American region around Cusco, Peru before the arrival of the Incas in the 13th century. The channels were used mainly as irrigation for the hundreds of terraces scattered across the valley.

Dr. Richard Miksad studied the water sources of Incamisana in Ollantaytambo, and led the team of researchers from the University of Virginia, Wright Water Engineers, Wright Paleohydrological Institute and archaeologists Arminda Gibaja Oviedo and Dr. Gordon McEwan, who conducted reverse engineering field research at the site.
The Incamisana is located north of the Manyaraki canal, in the Sacred Valley of the Incas at almost an altitude of 3,000 meters and approximately 70 kilometers northwest of Cusco. This sophisticated water complex consists of rooms, open spaces, beautiful complex of pools, ornamental fountains, waterfalls and buried channels.
The Incas had advanced the understanding of modern hydraulic principles. They were able to design the channels to avoid the so-called hydraulic jumps, or used them if necessary. This was especially difficult since the flow rates occur in different amounts in rainy seasons.

The Incas were also able to develop successful construction methods. For example, impermeable rock a coating was used to prevent water from leaking out of the channels. To protect against landslides and erosion of multi-level terraces foundations are connected to drainage channels.
Fourteen Ceremonial Fountains
The excavated temple has fourteen ceremonial fountains and additionally, three others that were never completed, and then the place was abandoned. There are also canals and well-planned and meticulously engineered conduit/distribution water system.
The Incamisana has platforms and elaborately carved stone niches; channels and fountains are moving water through the temple. The Incamisana played an important role, but in the design of these Inca watery systems, the ruler, as the most important official, would have access to fresh water before it was used by other people.
The network of roads, carefully planned, engineered, built and maintained connected the Incamisama sanctuary with the Inca Empire.
