The Maota lake was the main source of water for the Amber Palace. Water was lifted from the lake at Kesar Kyari Garden and was raised upto its mechanism operating at different levels:
Water was raised from the lake along the eastern facade of the Kesar Kyari employing animals and a number of pulleys and leathern bags. Water drawn in this manner was collected in storage tanks built on the terraces overlooking the garden. From there a sectioned clay pipeline approx. 125 meters in length channeled it onto another storage tank at the base of the second stage.
This stage is comprised of four separate but connected structure built in
ascending order each structure has its own pulley and rope arrangements using animals and had its own intake cum storage tanks at its base water has drawn from the lower most storage tank to the next one in leathern bags slung over the pulley with the rope.
Water was taken up from the first storage tank situated at the lowest level, up to the last one situated on the first floor of Balidan Gate [dhruv gate]. The structure are each between 10 to 13 meters in height which means that overall this system raised water to about 45 meters.
The final stage of the lift employment a Persian water wheel or Rehat. This system ‘Sakia in Persian’ appears to have been vogue as far as back as 500BC. It comprise of a long wooden shaft rotating on its axis supplied power to the axle of the drum which has a rope with a number of earthen bucket attached to it. The rotating drum moved the rope with its attached vessels elliptically down into and then up through the water in the tank. The pots filled up with water in the process and were then carried up, decanting their content into a collection channel at the very top of the mechanism. The water was then circulated in the palace through a network of earthen pot.
