Percolation Catch Basin

Solution for stormwater infiltration. An HDPE catch basin designed to collect surface runoff, promote deep percolation and contribute to groundwater recharge when site conditions allow.

The Soleno percolation catch basin is an HDPE stormwater structure designed to collect surface runoff and promote infiltration into the ground. With a perforated lower section, it allows water to percolate deeper into the soil and can contribute to groundwater recharge when site conditions are suitable.

Designed for source-control stormwater management, the percolation catch basin can be configured according to soil infiltration properties, flow rates and project requirements. It is especially relevant for municipal, commercial, institutional and residential projects where stormwater infiltration, runoff reduction and sustainable drainage are key objectives.

Smooth interior and exterior walls on the upper section, with a perforated corrugated lower section for roadway applications, resistant to loads CL-625, H-25 and HS-25.
Possibility of having the outer wall corrugated over the entire height of the catch basin for off-road application.
The risk of heaving due to the freeze-thaw cycle must be taken into account. Soil movement will not affect a catch basin with smooth exterior wall.
The percolation catch basin allows a deep percolation.
Available with polyethylene or cast iron grid.
Perforation available on the whole height of the structure.

Installation conditions and design precautions

Corrugated catch basins must be selected based on a non-roadway installation, whereas a catch basin with a smooth exterior wall can be installed in either roadway or non-roadway applications.
Precautions must be taken and the flows must be calculated to ensure that water returned to the soil does not weaken surrounding structures.
The perforation plan can be designed based on the percolation properties of the in situ soil.

Why Choose a Percolation Catch Basin?

A source-control solution for stormwater infiltration and groundwater recharge

A percolation catch basin collects surface runoff while promoting infiltration into the surrounding soil. Unlike a standard catch basin, which mainly conveys water toward a storm sewer network, the percolation catch basin helps manage stormwater at the source by allowing deep percolation.

This approach can help reduce surface runoff, limit pressure on downstream storm sewer systems and support groundwater recharge when soil conditions are favorable. The perforation plan can be adapted to the infiltration properties of the in-situ soil to help optimize system performance.

Made from HDPE, the percolation catch basin offers a lightweight, durable and corrosion-resistant solution for demanding underground environments. It can be configured based on the installation area, load requirements, grate type, perforation plan and project-specific stormwater objectives.

Common Applications

Source-Control Stormwater Infiltration

Municipal, Commercial and Institutional Applications

The percolation catch basin can be used in municipal, commercial or institutional projects where surface runoff collection must be combined with an infiltration function. It can be adapted according to site constraints, load requirements and connection needs.

Parking Areas, Streets and Paved Surfaces

In paved areas, surface runoff can be collected and directed into the percolation catch basin for infiltration into the soil. This solution can be considered when soil conditions, location and project requirements allow infiltration.

Sustainable Runoff Management

The percolation catch basin can be integrated into a sustainable stormwater management strategy to help reduce surface runoff. It is useful in projects that aim to limit pressure on existing storm sewer infrastructure.

Percolation Catch Basin or Dry Well?

Understanding the difference to select the right infiltration solution

The term “dry well” is often used to describe an underground structure that allows water to infiltrate into the soil, generally without a surface runoff collection function.

The percolation catch basin, by contrast, combines surface runoff collection with controlled infiltration. It collects water at the surface, directs it toward a perforated zone and promotes diffusion into the surrounding soil.

This makes it a more complete source-control stormwater solution, especially when the project must account for site conditions such as soil infiltration capacity, flow rates, nearby structures and surrounding constraints.

FAQ - Frequently Asked Questions about our Percolation Catch Basin

What is a percolation catch basin?

A percolation catch basin is a stormwater collection structure designed to collect surface runoff and promote infiltration into the ground. Unlike a standard catch basin, which mainly conveys water to a storm sewer network, a percolation catch basin allows water to percolate deeper into the soil when site conditions permit.

What is a percolation catch basin used for?

A percolation catch basin is used to manage stormwater at the source by combining surface runoff collection and infiltration. It can help reduce runoff, limit pressure on storm sewer networks and contribute to groundwater recharge.

What is the difference between a percolation catch basin and a dry well?

A dry well is generally used to infiltrate water into the ground, often without a dedicated surface runoff collection function. A percolation catch basin combines catch basin functionality with controlled infiltration by collecting runoff at the surface and directing it toward a perforated infiltration zone.

What types of projects can use a percolation catch basin?

Percolation catch basins can be used in municipal, commercial, institutional or residential projects where stormwater infiltration is desired. They may be integrated into streets, parking areas, paved surfaces or other drainage areas where runoff must be collected and infiltrated.

Can a percolation catch basin be installed in roadway applications?

Yes. Depending on the selected configuration and project requirements, a percolation catch basin can be designed for roadway applications. Applicable loads, wall type, soil conditions and installation requirements must be validated.

Can the catch basin be perforated over its full height?

Yes. Perforation can be provided over the full height of the structure when required. The perforation plan should be based on soil infiltration properties, flow rates and project design requirements.

Can a percolation catch basin contribute to groundwater recharge?

Yes. When soil conditions are favorable, the percolation catch basin allows water to infiltrate deeper into the ground and can contribute to groundwater recharge.

What grate options are available?

The percolation catch basin can be available with a polyethylene or cast iron grate, depending on the application, installation area, load requirements and project specifications.

How do you choose the right percolation catch basin configuration?

The right configuration depends on roadway or non-roadway installation, applicable loads, soil infiltration properties, flow rates, perforation plan, grate type and required accessories. For project-specific validation, it is recommended to consult a Soleno expert.
