When communities and technology meet: Municipal success stories

We are highlighting some of the projects and partnerships that have benefitted communities through the use of innovative approaches to sustainability.

Removing water
to save energy

The County of Antigonish When your community relies on sewage lagoons to process wastewater, disposing of the sludge requires fuel to pick up the materials, and energy to process it. With the purchase of a mobile dewatering truck from ABCO industries in Lunenburg, which removes liquids from the sludge, the municipality is now dewatering sludge at its solid waste management facility, and has been able to close two lagoons. The truck purchase was $475,000 with contributions through ecoNova Scotia and other funding streams totaling $250,000, and a municipal contribution of $225,000.

The answer is blowing in the wind

Anyone who has ever visited or lived in Amherst will tell you that there is an ample supply of constant and strong wind. Taking advantage of this renewable resource, the town is installing a 50 kilowatt wind turbine to help offset the power costs for the municipality’s wastewater treatment facility. Residents have been very supportive of these measures, which are expected to reduce power costs by more than 10%, which is hoped to total $50,000 - $70,000 in savings per year.

Solar-powered fire hall

Energy management initiatives are saving the Dayspring Volunteer Fire Department (Municipality of Lunenburg) thousands of dollars a year that can go into much-needed fire and rescue equipment and training for firefighters. The overall project cost was just over $17,000. Funding from the Province’s ecoNova Scotia Municipal Program fund covered approximately 50 percent, while Conserve Nova Scotia solar rebates covered approximately 12 percent. The balance was covered by the two project partners, Dayspring & District Volunteer Fire Department and Municipality of the District of Lunenburg. The fire department installed two solar heating systems, upgraded its insulation and installed higher efficiency lighting and a new furnace, which resulted in a 30% reduction in electricity use and a 35% reduction in furnace oil costs, far beyond the original savings estimates. "Investing in reducing energy consumption is a no-brainer. The thirty-four hundred dollars energy savings in the first year will help us purchase fire and rescue equipment that is getting more and more expensive. At this rate we will recover all our capital investment in less than ten years”: Councillor Frank Fawson.

Using audit information to reap rewards

The Municipality of East Hants saw several opportunities for energy management following an energy audit in 2009. A number of facilities were part of the audit, and several initiatives were undertaken, including lighting upgrades, building envelope upgrades, and solar water heating in the municipal pool. The municipality is also installing solar walls on two buildings to offset its seasonal heating demand. One building is located at the Waste Management Centre, and the other is at the Regional water treatment facility. The Municipality is anticipating energy savings from these sustainability measures as early as 2011. The energy savings will be used to pay off the debt and financing costs of the energy management projects. Connie Nolan, Chief Administrative Officer says “Staff and Council of the Municipality of East Hants are anxious to consider any sustainability project. With financial considerations being critical in today's economic climate it is important that the business case point to the wisdom of doing such projects and the funds provided by ecoNova Scotia helped to reduce the payback periods estimated for the projects they funded."

Preserving the past with new technology

The town office in New Glasgow was originally constructed as one of the first post offices in Canada in 1884. Historic buildings are notoriously difficult to insulate, heat and cool, but the installation of state-of-the-art heat pumps has generated cost-savings, even from modern heat pumps installed in 1999. Other retrofits to the library and local stadium are expected to result in total energy savings of nearly $35,000 a year. The heat pumps realized an air pollution reduction of 10 tonnes in the first four months of operation.

Keeping things cool in Inverness

The Dr. Bernie MacLean Cultural and Recreation Centre in the County of Inverness is a beehive of activity, especially in the winter months. Whether it’s hockey, curling or seniors’ skating, the centre is an important asset. Following an energy audit, the volunteer-run Inverness Arena Commission opted for a new energy efficient compressor for the rink, which runs on ammonia instead of freon. In addition, the lights were changed to high-efficiency fluorescent lighting in the rink, to reduce heat production and save electricity on lighting. With the new system up and running, the arena commission is anticipating a savings of 45% on their power bill in 2011, which will hopefully keep community rental costs stable, and ensure that the centre continues to offer programs for many years to come.

Face-to-face meetings without the travel

When you’re trying to coordinate meetings among all of the province’s municipalities, it can involve a lot of travel. The Association of Municipal Administrators of Nova Scotia (AMANS) is installing a video conferencing system that will help reduce the need for travel for AMANS staff, as well as municipalities. The municipal partners are very excited about this project, and are looking forward to having the video conferencing system in place in the near future. Not only will the project save mileage costs and reduce the organization’s carbon footprint, it will save staff a great deal of travel time that can be put toward other tasks. “The municipal community in Nova Scotia is always looking for ways to reduce its carbon footprint. This project, which allows for face-to-face communication even when people are miles away, should result in the reduction of greenhouse gas emissions, travel budgets and staff time away from the office. It's a move towards building healthier communities in Nova Scotia.” Janice Wentzell, Executive Director of AMANS.

A pool, a partnership, and a plan

An example of how one good idea can blossom into another good idea took place in the Municipality of the District of Guysborough. Council started out looking for a way to cut the costs for heating the water in the community pool. Propane heating was costing the community as much as $10,000 per year. After discussions with the Strait Regional School Board, the project grew to include solar panels for pool water heating, domestic hot water and air heating for Chedabucto Place, which houses the local P-12 school and the pool. The project will also incorporate ongoing learning opportunities by putting the solar panels in a visible place and setting up an interactive computer system to allow students to see how the temperature of the air and water are controlled. Solar panels are also going to be installed on the municipal building. It is hoped that the municipality will save about $8,800 a year on propane alone and the project will pay for itself in a little over five years. "This project started out as a Municipal concern of high energy costs for pool heating, but grew into an exciting Green Energy project that we are very proud of. Municipal Governments are to lead by example and to build partnerships, and this is a great example of our Municipality doing both. We continue to build on our partnerships with the Strait Regional School and the Province and through this process, we will all benefit environmentally and financially while providing a direct educational opportunity for our youth. This project is a 'win-win' for all."

Energy savings by the book

The People’s Place, a new library complex in Antigonish, will be a model for using sustainable energy practices. Funding from EcoNova Scotia allowed the project to put in a geothermal heating and cooling system, add energy efficient Solara windows to reduce glare, saving cooling and heating costs, and install self-venting skylights and controls. These measures will reduce the operating costs to the municipality, but equally important is the community’s support of these measures. Throughout the project’s evolution there has been a great deal of citizen engagement – and energy efficiency was identified as a top priority. Displays and a walking tour will demonstrate all the sustainable elements of the new building when construction is complete.

Stable water bills thanks to energy reduction

Water and wastewater treatment plants aren’t top of mind pieces of infrastructure for most citizens, but they are definitely necessary for municipalities. After an energy audit, the Municipality of the County of Richmond realized how much energy their wastewater treatment facilities were using. The county identified upgrades to treatment plants in Petit-de-Grat, Louisdale and Arichat that would be a worthwhile investment with lasting benefits. Improvements to the efficiency of the pumps and motors will reduce energy demand, and it is hoped that the project will pay for itself inside of five years. “Reducing our carbon footprint and energy consumption enables us to keep costs of operating these facilities down, which has a benefit to taxpayers. Hopefully sometime in the future we won’t have to raise taxes for waste water and potable water because of this investment.” Warden John Boudreau.
