They have hard keratinized skin.
Reptiles conserve water through their skin by having tough, dry scales that help prevent water loss. They also have efficient kidneys that can concentrate their urine to conserve water. Some reptiles, like certain desert species, can also retain water by adjusting their metabolic processes to minimize water loss.
We will be conserving water all summer long.
CAM pathway is the water-conserving process of carbon fixation.

Hard shelled or leathery eggs that can incubate/hatch outside of water, allowing them to migrate dry areas. Skin that prevents transpiration, allowing them to live on land without dehydrating. These would be primary...the third could be any of a number of adaptations, changes in locomotion, eye sight et cetera
Reptiles have developed an outer covering of scales or bony plates to retain their body moisture. Amphibian skin lets water pass in and out so amphibians must stay in or near a water source to keep their bodies from drying out. Amphibians develop from egg to larvae to adult in water. Reptiles do not have a larval stage.
Reptiles excrete their nitrogen waste mainly in the form of uric acid, which is a less toxic and more water-conserving waste product compared to ammonia or urea. Uric acid is excreted along with feces in a semi-solid or solid form, minimizing water loss from the body. This adaptation is important for reptiles living in arid environments where water availability is limited.
Conserving water means not wasting it. If you use the water in the icebox for something useful, even watering the garden or washing the car, then you are not wasting water. If there is a water shortage and you wash your car with a hose, for example, then you are not conserving water.

Tough skin and amniotic eggs were crucial adaptations for reptiles as they allowed these animals to thrive in terrestrial environments. The tough skin, which is often keratinized, minimizes water loss and provides protection from environmental hazards. Amniotic eggs, equipped with a protective shell and membranes, enabled reptiles to reproduce on land without the need for water, reducing dependency on aquatic environments for reproduction. Together, these adaptations facilitated the successful colonization of a variety of terrestrial habitats.
