Several considerations are involved in the design of pumping stations. It is required to make sure all the environmental considerations are met before the pumping station design is begun. The site should be checked for archaeological findings, and local and state regulatory agencies that may have jurisdiction should be consulted. Several codes such as NFPA 820, NFPA 70, and NFPA 101 provide guidance for fire protection for installations such as pumping stations. In addition to these documents, the designer should focus on choice of materials and fire suppression systems. Requirements for the design of ventilation systems for wastewater installations are provided in NFPA 820. Designers should be particularly aware that control and electrical equipment require an environment that has proper temperature control and protection against atmospheric conditions such as hydrogen sulfide gas. Pumping stations should be designed to handle flows from the entire service area. A pumping capacity that is adequate for the fully developed service area is to be installed or a pumping and force main capacity that could handle both the current needs and those of the immediate future with an adequate provision for economically adding to the capacity in the future is to be installed at the pumping station. The positive-displacement pumps are employed for thick sludges because these sludges are thixotropic and, after immobilization, high pressures are required to start their movement.
