Water world: After nearly 40 years, Peter MacLaggan leaves a liquid legacy
Every time someone turns on the tap in San Diego County, out flows the work of Peter MacLaggan. MacLaggan was the point man in the construction of the Carlsbad desalination plant, a nearly $1 billion public-private partnership that since 2015 has supplied nearly 10 percent of the potable water consumed in the county. … MacLaggan, 65, plans to retire March 31 after 20 years at the private company Poseidon Water and nearly 40 years in the water industry.
