Wimmera sustainability initiatives won three accolades at the Tidy Towns 2012 Sustainable Communities awards in Mornington on Saturday.
The state-wide awards are part of Sustainability Victoria's Keep Australia Beautiful program.
An Axis Worx e-waste program in Horsham's Wool Factory won a resource recovery and waste management award.
Dimboola Memorial Secondary College's six-star energy-rated, state-of-the art science and language building won an efficient energy award.
Northern Grampians Shire Council's Stawell stormwater alternative natural solutions project won a water efficiency award.
Wycheproof won Tidy Town 2012.
Axis Worx manager Bill Schmidt said the organisation and its supported employees were excited to win an award.
"We have been involved with e-waste recycling since January," he said.
"This award gives us confidence that we are on the right track.
"We are preventing a lot of waste from going into landfill."
Workers recycle parts from old goods include televisions, printers and mattresses.
Mr Schmidt thanked workers, Horsham Tidy Towns Committee members and Horsham, Ararat, Yarriambiack and Northern Grampians municipalities for their support.
Councils provide Axis Worx with e-waste to recycle.
Horsham Tidy Towns Committee chairman Don Johns congratulated the Axis Worx e-waste program for its win.
"This new program has been very successful and it can only get bigger and better," he said.
Dimboola Memorial Secondary College principal Rob Pyers thanked Dimboola Lions Club and Hindmarsh Shire Council for their roles in the school's win.
The award-winning science and language building opened in May and features include energy-saving lighting, solar panels and real-time energy and water use monitors.
Mr Pyers said it was great that students helped to design the new garden for the building as part of their Victorian Certificate of Applied Learning and Victorian Certificate of Education studies.
"We aim to be on solar power to run the school in the next two to three years," he said.
North Grampians Shire Council's Stawell stormwater alternative natural solutions project involved the construction of water quality treatment ponds, storage dams and transfer infrastructure across Stawell after years of drought.
The project captures 130 mega-litres of urban stormwater for re-use and environmental flows every year and has also helped address local flooding issues.
A Rainbow Primary School and Rainbow Secondary College project was a finalist in a community government partnerships category.
