A memorial event is set for June 14 in Englewood, Colo., for Richard P. Arber, vice president of engineer Hatch Mott MacDonald and an early champion of water reuse, who died on April 21 at age 68, says the firm.
No cause or location of death was given. Arber joined the company in 2011, after it acquired Richard P. Arber Associates, the Lakewood, Colo., firm that he founded in 1981.
