Our History

1977 - Laying the Family Foundation

At the age of 51, Anthony Rapoza Sr. started Delta Electric Motor and Generator Co. in New Bedford, MA with one of his nine children, 23 year-old Anthony Rapoza Jr. The company began by repairing motors and generators primarily for New Bedford’s marine, fishing and textile industries. Within the first four years, five of the brothers were working together.

1993 – Delta Electro Power Is Born

With 36 years of experience and success behind them, Anthony Sr. and his sons opened Delta Electro Power in Cranston, RI in 1993. The purchase of an existing business led to a huge expansion of Services, products and expertise for existing clients and a whole new customer base.

2007 – One Company, Eight Brothers

As Delta continued to grow, the rest of the brothers took notice of the great family-oriented culture and the growing opportunities to share their skill sets with the team. The remaining three sons joined Delta in the following years, with Tom joining the team in 2007 after working in sales in the printing industry for 15 years. Today, all 8 of Anthony Rapoza’s sons - Jim, Tony, Mike, Steve, Tom, John, Paul and Ernie - work together at the company their father started in 1977.

2011 – Delta Expands into the Pump Industry

In 2011, Delta expanded to include Delta Pump Group, a company that specialized in municipal and industrial pumps. Eric Novogrodski joined the company to further expand its presence in the pump market, which now consists of 16 direct pump lines.


Today, Delta has grown into one of New England’s leading municipal and industrial service companies. The company supports two generations of Rapozas, including Anthony Sr.’s sons and 21 of the 24 Rapoza grandchildren.

The brothers and Eric credit Delta’s growth to innovation, hard work and personal service. Their commitment to "treating clients like family" has distinguished them in the industry and pays homage to Anthony Rapoza Sr.’s vision from nearly 40 years ago.

With Delta, you have over 275 years of combined Rapoza family experience on your side.
