How to Maintain an Underground Detention System

Underground Detention System

Underground detention systems require simple maintenance. Learn about it here!

Underground detention systems are crucial pieces of infrastructure, particularly in highly developed areas or spots with hilly terrain. An underground detention system is a stormwater management system that acts like a giant French drain, detaining and slowly releasing stormwater into outlets that lead to local waterways, reservoirs, etc. Part of planning for an underground detention system installation is understanding how to care for it. Below, we’re discussing how to maintain an underground detention system.

Underground Detention System Maintenance

Regular Inspections

Conducting regular inspections is the best way to gauge the condition of your underground detention system. In the first year, it’s best to inspect it quarterly, and then annually after that. You want to check the inlets, outlets, surrounding surfaces, and storage chambers. Check for debris, unexpected plant growth, foul smells, clogged pipes, standing puddles, and soil erosion.

Routine Professional Cleaning

It’s necessary to hire a professional stormwater system cleaning service to remove any debris, sediment buildup, etc. An underground detention system is a confined space, which requires maintenance under OSHA guidelines. If you suspect a structural issue, as indicated by standing puddles or soil erosion, you can contact a stormwater management system contractor like Reliable Contracting.

Detailed Records

Keep detailed records of every underground detention system inspection. The information can be extremely helpful when contacting a cleaning or repair contractor and helps property managers and owners understand the history of the system’s condition.

Prompt Repairs When Necessary

If you do notice that structural problems could be present, prompt evaluations and repairs are necessary. Making small repairs now will prevent even bigger and more expensive problems later on; while keeping costs low is a pressing issue, keeping the community safe from disaster is even more important.

The Role of an Underground Detention System

If you are unsure which stormwater management system is best for your development, Reliable Contracting can give you expert advice and carry out the construction from start to finish, along with any pavement installation above it. When is an underground detention system most appropriate?

  • There is limited or no space for an above-ground stormwater drainage solution.
  • The local codes require the stormwater management system to be underground.
  • Hiding the stormwater management system is a part of the area’s curb appeal.
  • Putting the stormwater detention system underground promotes the highest safety.
