PORTLAND, Maine (AP) Mainers have given the green light to four bond initiatives totaling $200 million.

The proposals approved Tuesday mitigate wastewater pollution, upgrade transportation infrastructure and fund improvements at colleges and universities.

One of them directs $30 million over the next decade to municipalities with subpar septic systems that are leaking untreated stormwater and sewage into the ocean and nearby lakes and rivers. Some of the money also would go to homeowners for similar improvements.

A transportation bond would spend $106 million for maintenance of the state’s roads and bridges. The bulk of the money, $80 million, would be directed to busy roadways in greatest need of repair.

Two other bonds would provide $49 million to the University of Maine System and $15 million for Maine community colleges.
