The type of reservoir that may be required to store water overnight for peak use during the day time is a. Surface reservoir.

Here's why:

a. Surface reservoir: These are usually used to store water for various purposes including peak demand periods. They are designed to store large volumes of water and can easily accommodate the overnight storage for use during the day.

b. District reservoirs: These are typically used to serve a specific district or area. They may not have the capacity to store water overnight for peak use during the day for larger populations.

c. An elevated reservoir: These are typically used to create water pressure in the distribution system. While they can store water, their primary function is not storage for peak use.

d. A sedimentation tank: This is a part of the water treatment process where particles settle out of the water being treated. It's not a storage solution for peak use times.
