Two weeks ago, Charlotte Water moved to voluntary restrictions under Stage 1 of the Low Inflow Protocol. The drought has not cooperated. On Friday, the utility escalates to Stage 2 — mandatory restrictions, effective May 15.

The Catawba-Wateree River Basin, the region's water supply, has worsened steadily since last fall. Parts of Mecklenburg County have now reached "exceptional" drought status, the most severe classification on the U.S. Drought Monitor. The region has not been at this level since 2008, and has not operated under Stage 2 restrictions since 2009.

What the restrictions require

Lawn and landscape irrigation is limited to two days per week, between 6 p.m. and 6 a.m. only. Odd-numbered addresses water on Tuesdays and Saturdays. Even-numbered addresses water on Wednesdays and Sundays.

Residential swimming pools may be topped off — not filled — on Thursdays and Sundays only, during the same overnight window.

What is prohibited

Washing vehicles at home. Filling residential swimming pools. Operating decorative water features that do not support aquatic life. Non-essential power washing. Charity and fundraising car washes.

What is still allowed

Drip irrigation and soaker hoses. Hand-watering plants. Commercial car washes.

Fines and enforcement

Violations carry fines starting at $100. Charlotte Water's stated goal is a 5 to 10 percent reduction in total regional water usage.

The burn ban

Mecklenburg County implemented a separate mandatory burn ban on May 4, covering all county parks. The ban prohibits charcoal grills, propane and gas grills, fire pits, campfires, tiki torches, and candles.

Regional picture

Charlotte is not acting alone. Gastonia and Two Rivers Utilities are requiring the same 5 to 10 percent reduction, with fines up to $500 per repeat offense. Statesville has imposed mandatory restrictions with fines up to $600. Union County remains at Stage 1, allowing three irrigation days per week.

The voluntary restrictions covered in our April 26 report are no longer sufficient. The math has changed. The rules are now mandatory.
