The vehicular water-dispensing system is an enhancement to non-provisional application U.S. Ser. No. 16/695,416. Application U.S. Ser. No. 16/695,416 comprises a first retractable hose and a second retractable hose. The vehicular water-dispensing system comprises a logic module, a solenoid valve, a flow meter, and a plurality of vessel structures The logic module, the solenoid valve, and the flow meter controls the flow of drinking water into the plurality of vessel structures. The flow meter measures the flow of drinking water discharged from the solenoid valve. The logic module, the solenoid valve, and the flow meter are electrically connected to form a feedback loop that controls the flow of drinking water through the solenoid valve. Each of the plurality of vessel structures is a mechanical structure that contains the drinking water in preparation for consumption. The plurality of vessel structures automatically refills the drinking water after the drinking water has been consumed.
