Drain pipe only works if the route works
Solid drain pipe carries collected water from a catch basin, downspout or other approved inlet to a lawful outlet. It is different from perforated French-drain pipe, which collects subsurface water along the trench.
We look at the inlet, elevation, pipe path and outlet as one system. A pipe with poor fall, weak bedding or nowhere useful to discharge can turn a drainage project into buried disappointment.
TRACE THE DRAIN ROUTE
Drain-pipe excavation and installation support
The project should connect water collection, conveyance and discharge—not treat each piece separately.
Collection points
Prepare catch basins, area drains or downspout connections at the places water actually collects.
Solid pipe routes
Excavate, bed and install or support installation of pipe with the specified slope and cleanout access.
Outlets and restoration
Connect to an approved discharge point, protect the outlet and restore surrounding grades.
Stormwater connections and discharge points can require City approval. Do not assume a street, ditch or public system is available without confirmation.
Stormwater rules shape the outlet
Lake Oswego’s stormwater guidance distinguishes project types by disturbed area and new or replaced impervious surface. Work near lakes, streams, canals or wetlands can trigger additional erosion-control review.
We keep the pipe route tied to the approved drainage plan and practical maintenance. Cleanouts, accessible structures and a stable outlet are easier to build now than excavate again later.
CALL (971) 242-9163Connect the low point to a real outlet
The useful plan starts at the water source and follows the grade all the way to discharge.
01 — Identify collection
Confirm which surfaces feed the inlet and how much area contributes water.
02 — Check route and fall
Lay out pipe, structures, utility conflicts and the approved outlet elevation.
03 — Excavate and install
Prepare bedding, set structures and place pipe to the specified slope.
04 — Test and restore
Check flow, protect the outlet, backfill and reconnect the finished grade.
Lake Oswego drain-pipe FAQs
What is the difference between drain pipe and a French drain?
Solid drain pipe carries water from an inlet to an outlet. A French drain uses perforated pipe and clean rock to collect subsurface water along the trench.
Can you connect downspouts to underground pipe?
Often, yes, when there is an approved route and outlet. The design should include accessible cleanouts and avoid sending roof water where it creates a new problem.
How much slope does drain pipe need?
It depends on pipe size, system design and outlet conditions. We follow the approved plan rather than applying one number to every property.
Have a low spot or a pipe route in mind?
Show us the inlets, outlet and elevation changes. We’ll help determine what needs excavation, where structures belong and whether the proposed route makes sense.
