Interstate Waste Services, Inc. (IWS), a provider of solid waste collection, disposal and recycling services, has acquired Grand Sanitation Service, Inc., an independent hauler known for its all-inclusive service offerings.
Founded in 1998, Grand Sanitation has proudly served several counties in North and Central NJ, including but not limited to Union, Middlesex, Somerset and Morris Counties, providing a full spectrum of hauling services including residential, commercial, roll-off, and cleanup solutions. Over the years, the company has maintained steady growth across various segments, earning a strong reputation for reliability and service excellence.
As part of the acquisition, IWS will integrate all of Grand’s commercial and residential collection, roll-off and municipal services, its team of employees, and a fleet of more than 50 vehicles into its operations. These additions to the team further strengthen the company’s operational capacity and reinforces the commitment to delivering first-class service.
The acquisition of Grand Sanitation Service marks another milestone in IWS’s expansion across the tristate area. It follows a series of strategic moves aimed at strengthening IWS’s market leadership, including Seaside Waste Services in Central and Southern New Jersey, Pinto Service, Inc. in northern New Jersey, Oak Ridge Waste & Recycling in Southwestern Connecticut and Suburban New York, as well as Marangi Disposal, the largest independent hauler in Orange and Rockland Counties, New York.
