The updated Drought Contingency Plan primarily affects high-water-use customers during severe drought stages (3–5). Households using less than 6,000 gallons of water per month, which is considered average usage, will not be subject to surcharges. However, higher water users, particularly those relying on irrigation, may face increased costs, with surcharges ranging from $4.18 to $4.89 per thousand gallons during severe drought stages. These measures aim to conserve water resources and ensure long-term supply sustainability for the region.
