Plumbing issues worth knowing about
Drain and sewer lines that are 45 to 65 years old
In a house from the 1960s or 70s, the buried sewer line to the street is often the oldest plumbing on the property. Roots and shifted joints in that line cause slow drains that keep coming back. A camera inspection shows the problem before anyone digs.

Quick permits for common jobs
Centennial issues "One-Stop" permits for water heaters, gas lines and irrigation lines, with review in one business day. A water heater swap shouldn't be held up by the paperwork.

Leaks between the street and the house
The water service line from the curb stop to your house is usually the owner's to repair. A patch of yard that stays wet, or a meter that keeps moving with every tap off, points to a leak in that line.

Questions from Centennial & Greenwood Village homeowners
Is Centennial Water the same as the City of Centennial?
No, and the names cause real confusion. Centennial Water and Sanitation District serves Highlands Ranch. Most City of Centennial homes in 80121 and 80122 are served by Southgate or directly by Denver Water.
Water is coming up in the street. Who do I call?
Your water district, not a plumber. For Southgate customers that's 303-779-0261, which is answered around the clock for main breaks and sewer backups.
Do I need a permit to replace a water heater in Centennial?
Yes. Colorado requires a licensed plumber, a permit and an inspection. Centennial handles it as a One-Stop permit, reviewed in one business day.
