Mainstream Engineering Awarded Contract from the Naval Sea Systems Command to Develop Greywater Recycling System
Navy vessels such as littoral combat ships (LCS) must follow local and federal regulations when disposing of wastewater in littoral waters. These strict regulations prohibit discharging greywater in many areas. Therefore, the greywater generated by the galley, scullery, and other shipboard operations must be stored aboard the ship until the wastewater can be safely offloaded shoreside or at sea outside littoral water limits.
LCS holding tanks are normally designed to only support a 12 hour period of operation, and retrofitting a larger tank is expensive. To avoid the frequent, expensive visits to offload waste ashore, Mainstream Engineering is now adapting a greywater recycling system that they originally developed for recycling Army kitchen wastewater for use aboard ships.
