Wastewater Pumps

STH can provide detailed commercial and municipal clean water and wastewater pump specifications, application engineering, project budgets and training to owners and engineers for your specific commercial and municipal water and waste water applications.

STH has a wide range of submersible storm water, wastewater and clean water pumps to help reduce maintenance requirements and costs, while delivering years of reliably optimum service.

These pumps are designed for submerged use in network pumping stations, wastewater treatment plants, public buildings and housing projects.


STH offers a complete line of storm water and sewage pumps, lift-out rail assemblies, controls and accessories to meet your needs to include:

  • Grinder Pumps
  • Non-Clogs Pumps
  • Elevator Sump Pumps


Clean water and the proper disposal of waste water demands the utmost in pumping reliability and performance. STH can provide pumping solutions for municipal raw water intake and distribution, collection systems, pumping stations, treatment plants and chemical dosing for pumping water, sewage, sludge, corrosives, caustics and industrial by-products. All sizes available with special pump-end materials of construction to meet specific application requirements including:

  • Submersible Pumps
  • Submersible Turbine Pumps
  • Dry-Pit Submersible Pumps
  • Packaged Lift Stations
  • Chemical Dosing
  • Axial and mixed flow pumps


Low Pressure Sewer Systems (LPS) Incorporating Grinder Package Systems Offer Cost Effective Solutions for Cities

Municipalities may choose to invest in a low pressure sewer system (LPS) as an alternative to using gravity sewers or septic tanks. Low pressure sewer systems (LPS) are low-head pressure waste water collection and treatment. The low pressure sewer system (LPS) is built with an interceptor tank and a chamber unit, which contains a submersible electric pump.

The low pressure sewer system (LPS) is ideal to design a grinder package system with it, as each unit requires its own grinder pump to turn solids into effluent that can be pumped to the municipal waste water treatment facility.


Mixers make sure that particles remain evenly distributed in wastewater and sludge, preventing sedimentation and supporting treatment processes.

STH can provide a range of mixers from small-scale mixers, ideal for prefabricated pumping stations, to large-scale flowmakers created for large tanks and basins.

Typical application areas:

  • Sewage pumping stations
  • Wastewater treatment plants
  • Industrial processes
  • Agriculture
