The town of Springhill frequently must declare a water emergency, making it temporarily unlawful to use water for such nonessential purposes as car washing  These emergencies could be avoided if Springhill would introduce permanent economic incentives for water conservation
Actually, Springhill discourages conservation because each household pays a modest monthly flat fee for any amount of water below a certain usage threshold, and a substantial per-liter rate only after the threshold is reached
The threshold is kept at a high enough level to exceed the water requirements of most households in Springhill.
