Plumbing and Fire Protection Services

Plumbing and fire protection design have become critical parts of many projects performed by Henneman Engineering.  With the construction of new facilities and renovation of existing facilities, plumbing and fire protection issues must be addressed quickly and effectively to meet the demands of the project schedule.

While most projects rely on water supplied by public authorities, it is of vital importance to understand the availability and relationship to the demand required by the plumbing and fire protection systems.

Henneman Engineering employs plumbing designers and engineers with experience in domestic water, sanitary, natural gas and fire protection systems.


Typical work in these areas involve:

  • Domestic water booster pump systems
  • Back flow prevention
  • Hot water generation and distribution
  • Sanitary sewer design with invert elevations
  • Indirect waste handling
  • Fire pumps
  • Hose stations
  • Fire protection zoning
  • Double interlocked pre-action systems for critical areas such as computer rooms, elevator machine rooms and elevator shafts or hoistways
