Imperial splits down the middle: newer subdivisions on sewer near I-55, older homes on septic along the side roads and hills. Service for the septic half of 63052.
Local Septic Service
Drive Imperial and you can see its two wastewater worlds from one road. Near the Interstate 55 corridor, subdivisions run on municipal sewer. A few turns away — down Old Lemay Ferry Road, Frisco Hill, and the older lanes toward Kimmswick — homes sit on larger, hillier lots where septic systems still do the work, as they have since those houses were built.
The septic side of Imperial tends to be older housing on rolling ground: rocky soil on the hills west of the interstate, systems sized for the smaller households of another era, and steady real-estate turnover as buyers trade city prices for Imperial's space. (Locals know the Mastodon State Historic Site marks the area's deep history — the septic systems are newer than the mastodons, but some of the tanks out here feel close.)
Pumping, repair, inspections, and installation for Imperial's septic homes — from the Kimmswick edge to the hills above the interstate.
Typical local pricing is in the Jefferson County cost guide.
Common Questions
Sewer lines were extended subdivision by subdivision, not street by street. If your home wasn't in a sewered phase, it kept its tank. Your water bill settles it: no sewer charge, you're on septic.
The county pattern applies: $300–$600 for a standard tank, most near $450. Full ranges are in the cost guide.
Often, yes — aerobic treatment handles slow-draining rocky soil better than a conventional field alone. It comes with real maintenance duties, covered on the aeration page.
