Ni Pacolet Milliken Utilities, South Carolina

After transitioning this project from another contractor, ESG began its relationship with Ni Pacolet Milliken in February 2016.  Ni Pacolet Milliken is a private, family owned investment company that owns and manages various assets in the real estate, energy, and infrastructure industries. ESG operates and maintains their wastewater system which consists of 3 wastewater plants and 80 lift stations spread throughout a 295-square-mile service area.

ESG’s team of 29 associates has significantly created operational efficiencies and stronger wastewater system redundancy by implementing a CMMS, self-performing numerous repairs, and returning multiple pieces of unutilized rented equipment. ESG has also performed a condition assessment and prepared a 12-year equipment repair/replacement plan. ESG’s in-sourcing and asset management strategy will minimize operations and maintenance costs, reinforce compliance efforts, reduce reliance on outside contractors, and prolong the life of Ni Pacolet Milliken’s wastewater utility assets.
