Arlington Heights FAQ
Are lawn watering rules statewide?
No. Rules are tied to each Lake Michigan allocation permit, so suburbs sharing the lake source have similar odd-even and afternoon bans, while inland communities on groundwater set their own conservation rules or none.
Do these rules apply to drip irrigation?
Drip and hand-held hose watering are usually exempt from sprinkling restrictions because they use much less water. Check your municipal code; some still impose hours-of-day limits during declared drought emergencies.
Chicago FAQ
Does Chicago ever ban lawn watering completely?
Only during a declared water emergency. Because the city's supply is Lake Michigan rather than a stressed reservoir, full bans are rare and usually triggered by main breaks or pressure incidents, not drought.
Can I use a soaker hose during restricted hours?
Yes. Drip irrigation, soaker hoses, and hand-held hose watering with a shutoff nozzle are exempt from MCC 11-12-460 sprinkling-hour limits because they use far less water than overhead sprinklers.
