Drop a 💧 in the comments if you’re ready for a stronger water future, because today’s the day. Drilling officially begins on our two ASR test wells, a real step toward more reliable water right here in Mountain House. 🌊

Over the next three to four months, crews will drill, test, and gather the data we need to find out whether storing water underground can work for our community.

We’ll keep you posted every step of the way. This is your community, and you deserve to know what’s happening in it. Curious about the bigger picture? See the full project page here: https://www.mountainhouseca.gov/430/ 💧

Clean water on tap and no impact from the Medline Fire? Drop a 💧 in the comments if you’re grateful for reliable water in Mountain House. Based on information from Inframark, our drinking water was not affected. Mountain House continues to meet every water quality standard, with no changes to our source water, treatment, or quality since the fire. Operations staff monitor conditions daily, and routine sampling continues across the system. Why are we confident? The fire was outside our raw water watershed, winds blew away from our water source, our Air Quality Index stayed “Good” the whole time, and the Division of Drinking Water reported no concerns.

We’ll keep working with Inframark and regulatory agencies, and we’ll notify you right away if anything changes. Learn more at mountainhouseca.gov.

Drop a 👍 if you think safety and fairness go together. 🚦 Our Director of Public Safety, Rex Osborn, breaks down how the Mountain House Red Light Safety Camera Program really works.

Every citation is backed by real evidence. Photos and video get reviewed before any ticket goes out, and if there is no violation, none is issued. Get one anyway? You can see exactly what the camera saw and contest it.

We get it. We are drivers too. 🚗 Same facts, no guesswork. Our goal is simple. Safety, fairness, and consistency for all of us. 💙

Big news for our water future is about to break ground right here in Mountain House. Tag a neighbor who should know what’s happening with our two new wells. 💧 Starting Monday, June 22, crews begin testing two new wells right here in town. This is the start of something we’re excited about: finding smarter ways to keep our water reliable for years to come. All week, we’ll share what’s happening, what you might notice, and why it matters. The more neighbors who know, the stronger we plan together.
