When heavy rain leaves water pooling in a yard, parking area, roadway, or drainage system, the problem may be more than temporary standing water. Poor drainage can overwhelm existing systems, contribute to erosion, damage landscaping or pavement, and carry sediment and other pollutants into local waterways. Stormwater management helps control where runoff goes and how it is collected, conveyed, filtered, and released.
All Septic & Sewer provides stormwater drainage and maintenance services for properties throughout King, Pierce, and Thurston Counties. The right solution depends on the property, the amount of runoff, existing drainage infrastructure, soil conditions, and how water needs to move across the site.
Why Stormwater Management Matters
Rainwater naturally moves across roofs, driveways, roads, lawns, and other surfaces. During heavier storms, the amount of runoff can exceed what soil or an existing drainage system can absorb at one time. This can result in standing water, flooding, erosion, or overloaded drainage features.
Runoff can also pick up sediment, oil, chemicals, debris, and other pollutants as it moves across developed surfaces. Local stormwater programs are designed in part to reduce these impacts and protect waterways. Pierce County’s current program emphasizes runoff management, pollution reduction, erosion control, and low-impact development practices.
A properly designed and maintained drainage system gives runoff somewhere to go while reducing the risk of water collecting where it should not.
Installation of Underground Infiltration Trenches
An infiltration trench is an underground drainage feature designed to temporarily store runoff and allow water to infiltrate into suitable surrounding soil. The system typically uses an excavated trench filled with stone or other appropriate aggregate, along with components that direct runoff into the trench.
The size and design should be based on the property and applicable requirements rather than assuming every site can use the same trench. Soil conditions, available space, groundwater, runoff volume, and the amount of impervious surface can all affect whether an infiltration system is appropriate.
Pierce County currently provides design guidance and sizing tools for residential infiltration trenches, while its stormwater manual includes specific details for infiltration trench systems.
All Septic & Sewer can help property owners address underground drainage needs and determine what type of system fits the site.
Clean Water Catch Basin Maintenance
Catch basins collect runoff and direct it into a drainage system. They can be found around parking areas, roads, commercial properties, and other locations where surface water needs to be collected and conveyed.
Because runoff can carry leaves, sediment, gravel, trash, and other debris, catch basins require maintenance. When debris accumulates, it can restrict flow and reduce the capacity of the system.
All Septic & Sewer provides catch basin cleaning using equipment suited to the condition of the basin. Depending on the situation, cleaning may involve a clamshell truck or a vactor truck. The appropriate approach depends on how much material has accumulated and what the system requires.
Regular maintenance is an important part of stormwater management because drainage systems need to remain open and functional when significant rainfall occurs.
Cleaning and Replacing Stormwater Cartridge Filters
Some drainage systems use cartridge filters or other treatment components to remove pollutants from runoff. Depending on the system, these filters can be designed to capture sediment, metals, hydrocarbons, oils, or other contaminants.
Filters do not last indefinitely. As material accumulates, the cartridge may become less effective or require replacement. The appropriate maintenance schedule depends on the type of filter, the property’s runoff characteristics, and the manufacturer’s or system requirements.
All Septic & Sewer can clean or replace cartridge filters based on the needs of the system. Keeping these components maintained helps the drainage system continue performing its intended treatment function.
Repairing Catch Basins, Pipes, and Stormwater Ponds
A drainage system relies on multiple components working together. Catch basins collect water, underground pipes convey it, and ponds or other facilities may temporarily store or manage the runoff.
When one component becomes damaged or clogged, it can affect the performance of the larger system. Signs of a drainage problem can include persistent standing water, overflowing catch basins, visible erosion, slow drainage, damaged pipe sections, or a stormwater pond that is not functioning as expected.
This service should account for the entire drainage path rather than focusing only on the location where water happens to collect. Depending on the problem, work may involve cleaning, repairing, replacing, or improving a drainage component.
Stormwater Management Services for Pierce, King & Thurston Counties
Requirements and drainage conditions can vary between jurisdictions and individual properties. A system that works appropriately on one site may not be suitable for another because of differences in soil, slope, development, runoff, groundwater, or existing infrastructure.
All Septic & Sewer serves properties throughout Pierce, King, and Thurston Counties. In Pierce County, current county guidance addresses infiltration trenches, catch basins, ponds, pipes, and other facilities.
King County also maintains requirements and technical guidance for stormwater drainage and surface water management, including its current Surface Water Design Manual.
Thurston County‘s program addresses runoff from development and existing properties, including drainage systems, maintenance, inspections, and pollution prevention.
That local context matters when planning or maintaining a drainage system.
How All Septic & Sewer Approaches Drainage Work
All Septic & Sewer works with residential and commercial properties throughout the region. Stormwater projects can involve everything from maintaining an existing catch basin to addressing underground drainage, filters, pipes, or ponds.
The company approaches each project based on the existing system and the conditions of the property. That helps determine whether the work should focus on cleaning, repair, replacement, or installation.
Why Choose All Septic & Sewer?
These problems are often connected to the way several drainage components work together. A clogged catch basin can affect downstream piping. A damaged pipe can change where runoff exits. A poorly functioning infiltration feature can leave water standing on the property.
All Septic & Sewer provides drainage services across Pierce, King, and Thurston Counties and has experience working with catch basins, infiltration systems, filters, pipes, and ponds.
The goal is to address the drainage problem while considering how the individual component fits into the larger system.
Frequently Asked Questions
Stormwater management includes the systems and practices used to collect, control, convey, treat, infiltrate, or otherwise manage runoff from rain and other precipitation. Depending on the property, this can involve catch basins, underground pipes, infiltration trenches, ponds, filters, swales, or other drainage features. The appropriate system depends on the site’s layout, soil, runoff, existing infrastructure, and applicable local requirements.
An infiltration trench is an underground drainage feature designed to temporarily hold stormwater and allow it to infiltrate into surrounding soil. It typically includes an excavated trench containing aggregate and other components that help distribute runoff. Whether an infiltration trench is appropriate depends on soil conditions, groundwater, available space, runoff characteristics, and applicable design requirements. Pierce County provides specific guidance for residential infiltration trench systems.
There is not one cleaning schedule that applies to every catch basin. The frequency depends on the amount of sediment, leaves, trash, and other material entering the system, along with the property’s surroundings and how quickly the basin fills. Regular inspection can help identify when cleaning is needed. Pierce County notes that private stormwater systems require periodic maintenance, and some properties have specific inspection and reporting obligations.
Common warning signs can include water that remains pooled after rainfall, overflowing catch basins, visible erosion, damaged pipes, unusual sediment buildup, or drainage areas that no longer empty as expected. These symptoms can have different causes, so the visible problem may not be the only component that needs attention. Inspecting the drainage path can help determine whether cleaning, repair, replacement, or another solution is appropriate.
Yes. Stormwater systems can collect sediment, leaves, debris, and pollutants over time. Catch basins, filters, infiltration features, pipes, ponds, and other components can become less effective when they are not maintained. Pierce County states that private stormwater systems require periodic maintenance and identifies catch basins, pipes, ponds, swales, and other facilities as common components of private systems.
No. Drainage solutions are site-specific. Soil conditions, slope, impervious surfaces, groundwater, property size, existing drainage infrastructure, and the amount of runoff can all affect what type of system is appropriate. Local requirements can also differ between Pierce, King, and Thurston Counties. A solution should be evaluated based on the actual property rather than applying the same design to every site.
A properly designed and maintained drainage system can help control runoff and reduce the chance of water collecting in unwanted areas. However, no drainage system can eliminate every flooding risk, particularly during unusually heavy rainfall or when downstream systems are overwhelmed. The goal is to manage runoff according to the site’s conditions and the capacity of the drainage system.
