Pumping and cleaning of hydrodynamic separators
Maintenance, cleaning, and recommissioning of stormwater management systems
Hydrodynamic separators play an essential role in stormwater management by retaining sediments, hydrocarbons, and contaminants before they reach municipal networks or natural environments. Over time, these systems accumulate sludge, debris, and floating materials that impair their performance.
At Sanivac, we offer a turnkey service for the pumping, cleaning, and maintenance of hydrodynamic separators, including Stormceptor-type models and other similar systems used in parking lots, commercial, industrial, and municipal sites.
What is a hydrodynamic separator and where is it used ?
A key component of modern stormwater infrastructure
A hydrodynamic separator is a stormwater treatment structure designed to capture and retain :
- sediments,
- hydrocarbons,
- floating materials,
- certain urban contaminants.
These systems are mainly found :
- beneath commercial and industrial parking lots,
- in shopping centers,
- on municipal sites,
- near roads and transportation infrastructure,
- in stormwater management projects.
Regular maintenance is essential to ensure their effectiveness and meet environmental requirements.

Complete pumping and cleaning of separators
Restore system capacity and performance
Sanivac performs complete pumping of sludge, sediments, and accumulated materials inside hydrodynamic separators. Our teams then carry out a thorough cleaning of internal components in order to :
- restore hydraulic capacity,
- ensure optimal flow,
- prevent obstructions and backups,
- extend the service life of the separator.
Our specialized equipment allows us to intervene efficiently, even in deep structures or those with restricted access.
Cleaning and maintenance of filters and internal components
Rigorous maintenance for long-lasting performance
Some hydrodynamic separators are equipped with filters or cartridges that require specific maintenance. Sanivac provides :
- cleaning or removal of filters,
- the safe disposal of captured materials,
- proper reinstallation of components,
- visual verification of proper system operation.
This step is essential to ensure that the separator continues to effectively treat stormwater after the service.
Preventive maintenance and emergency response
A flexible approach tailored to your needs
Sanivac offers scheduled preventive maintenance services, recommended to prevent overloads, overflows, and loss of efficiency in hydrodynamic separators. These interventions are ideal for :
- municipalities,
- property managers,
- commercial and industrial sites.
We also respond in emergency situations, including :
- after incidents,
- following major construction or renovation work,
- during obstructions or overflows.
Our turnkey service helps quickly restore your facilities and get your drainage system back to proper working order.

A hydrodynamic separator is a stormwater management structure designed to capture and retain sediment, hydrocarbons, and floatable debris before the water is discharged into the municipal system or the environment. Stormceptor-type systems are among the most widely used in parking lots, commercial sites, and municipal infrastructure.
These separators are mainly found beneath commercial, industrial, and municipal parking lots, near roadways, in shopping centers, institutional buildings, and stormwater management projects. They are often buried underground and connected directly to stormwater piping.
Over time, sediment, sludge, and hydrocarbons accumulate in the separator, reducing its capacity and efficiency. Without maintenance, this can lead to blockages, overflows, and environmental non-compliance. Cleaning restores system performance and helps protect downstream networks.
Frequency depends on stormwater volume, site traffic levels, and the surrounding environment (parking lot, roadway, construction site). In general, annual or semi-annual preventive maintenance is recommended, with additional inspections after major construction work or significant rainfall events.
Yes. Sanivac provides emergency response in cases of overflows, blockages, after incidents, or following construction projects that generate excessive sediment buildup. Our teams deliver rapid pumping, thorough cleaning, and an efficient return to service of the system.
The turnkey service includes pumping out accumulated sludge and debris, cleaning internal components and filters, visually checking proper operation, and managing the pumped material by transporting it to authorized disposal sites. This approach helps restore your piping and stormwater system to optimal working condition.
