The correct choice is that surface and drip irrigation systems and sand filters typically require a pump tank. This is because these systems often need to distribute water or effluent at a certain pressure to ensure proper functioning. For instance, in surface and drip irrigation, a consistent water pressure is necessary to deliver water uniformly across the entire field. Similarly, sand filters might require a pump tank to maintain adequate water flow and pressure for effective treatment.

In contrast, composting toilets, septic tanks, and pit latrines operate on gravity or passive systems rather than relying on pumps. Composting toilets use natural processes to decompose waste without requiring pumps for fluid movement. Septic tanks rely on gravity to transport waste from the household to the tank and do not inherently require pump tanks unless there is a specific need for effluent removal. Pit latrines collect waste in a hole dug in the ground, working entirely on gravity without the need for pumping systems to manage waste.

Hence, the necessity for a pump tank is closely linked to the operational demands of surface and drip irrigation systems and sand filters, highlighting the correct answer in this context.
