Buried exterior sump pump discharge lines for KC metro homes: underground runs from your discharge stub to daylight or a pop-up emitter 15–25+ feet from the house, freeze-safe design, continuous slope, lawn restored. Typical single line $300–$700 like our buried downspout extensions. Stops your pump recycling the same water in a loop.
Your sump pump might be pumping the same water over and over.
If your sump discharge dumps water a few feet from the foundation, gravity takes it right back down the wall to the drain tile — and your pump lifts it again ten minutes later. It's the most common sump setup in Kansas City, and it's why pumps burn out and basements stay damp. Premier Gutters KC buries exterior discharge lines that carry sump water far from the house to a daylight outlet or pop-up emitter, sloped to self-drain so winter can't freeze them shut. Exterior stormwater work only — done right, photographed before backfill.
We pick up at the discharge stub outside your foundation wall and build everything from there — the exterior stormwater run, engineered for KC winters.
Water discharged at the foundation returns to the sump pit through the same soil that flooded it. Breaking that loop is the single highest-value drainage fix on most KC homes with a running sump — and it pairs naturally with burying the downspouts in the same trench day.
A typical buried single discharge line runs $300–$700 — 15–25 ft from the house, Schedule 40 PVC or corrugated, to a daylight outlet or pop-up emitter, trench restored. Add it to a whole-house buried downspout project ($1,500–$3,500) and it shares the dig. Pop-up emitters add $150–$300. Cast iron sump pump replacement (interior) is $1,500–$2,800 per our published pricing. Free quotes.
Most sump discharges dump water 3-6 feet from the house through a short corrugated hose. That water soaks straight back down the foundation wall and returns to the sump pit - so the pump runs constantly, moving the same water in a loop. A buried line carries the water 15-25+ feet away to daylight or a pop-up emitter, breaking the cycle and cutting pump wear dramatically.
Not if it's built right. We run the buried portion at continuous slope so it fully drains between pump cycles - water that doesn't sit can't freeze - and use freeze-relief fittings at the connection point so that even if ice ever blocks the line downstream, the pump still has a relief exit instead of dead-heading against an ice plug.
Our specialty on this page is the exterior buried discharge run - the part outside your wall. Cast iron sump pump replacement is listed on our pricing page at $1,500-$2,800; interior plumbing work is coordinated so everything inside the wall is handled to code.
Buried discharge runs price like our buried downspout extensions: $300-$700 for a typical single line, 15-25 feet from the house to a daylight outlet or pop-up emitter, with restoration of the lawn over the trench. Longer runs and runs routed under walks are quoted from the actual site. Quotes are free.
They can share a trench but should not share a pipe. A sump line surging into a downspout pipe can back-flow into other downspouts. We run them parallel in one trench - one dig, two dedicated lines - which keeps cost down without cross-connecting systems.

Same trench, same day — the natural pairing.
When the sump runs constantly, the yard usually needs collection too.
