Perfect for most municipal and utility applications, our standard drop boxes are engineered to fit typical lift station dimensions and configurations. The internal swirl design minimizes turbulence, keeps solids suspended, and prevents grease from settling - reducing the need for frequent cleanouts.

• Ideal for retrofit or new construction

• Compatible with most existing manholes

• Fast installation with minimal disruption

Have a challenging setup? MS HydraFlow offers custom-built drop boxes tailored to your site's unique piping, flow rate, or dimensional needs—delivering the same benefits of reduced maintenance, fewer clogs, and cleaner operation.

• Custom designs based on site-specific requirements

• Suitable for irregular manhole sizes or complex inlet arrangements

• Built with the same proven swirl-flow efficiency as our standard models

We offer multiple construction options to meet your durability, corrosion resistance, and weight requirements:

• Stainless Steel 316
  Corrosion-resistant and built to last in even the harshest environments.

• Composite
  Lightweight and cost-effective, ideal for installations where metal is not preferred.

Each material is selected based on durability, system compatibility, and long-term performance.
