Havre's Wastewater Woes Solved By Beer

Finding ways to reuse brewery waste can save water treatment plants money. In Havre, Montana, Triple Dog Brewing has entered into a partnership with the town’s wastewater treatment plant, supplying discarded barley to feed the plant’s microbes. The barley replaces commercial bacteria feed, which would have cost the plant thousands of dollars. The town was also able to avoid having to do costly upgrades to its water treatment plant. Other towns are looking to this process for inspiration.

Water conservation has been a hot topic for the last decade. As nations continue to search for ways to ensure a safe water supply for future generations, some places are looking to history for answers. Taking a page out of the 1970s water shortage era for Orange County in California, these places are finding ways to recycle sewage water into drinkable water.

Thanks to years of government intervention, the city of Copenhagen has almost perfectly clean water — even better than bottled water. Denmark utilizes overflow barriers, underground water storage, and rerouted wastewater to keep their public water sources clean. Public awareness and a water tax also contribute to the city's success so that residents conserve and value their water (using only 26 gallons a day as opposed to the 80-100 gallons that Americans use).

Israel has an abundance of water and independence from climate conditions through public ownership and government management of all water, a water-respecting culture, and innovative agriculture practices.

Though once the rivers were afoul with pollution and the carcasses of poisoned fish and the water from taps was too hazardous to drink, Denmark now boasts some of the world's cleanest drinking water and some of it's most comprehensive programs for good water management. The Danish government is looking to help other nations replicate their success, leveraging technology and collaboration to better manage water treatment and conservation for all.

Haunted by a 1962 drought in the town of Westminster, Colorado, the city's planners now incorporate water data in their planning processes to ensure that they never face the same sourcing issues again. By breaking down the silos between its water management and planning departments, the town has figured out how to manage its finite water resources, even in the face of a ballooning population. Now, other towns are following suit.

Mysuru has become a gleaming example for solutions to India's vaster struggles with solid-waste management, toilet construction, sanitation strategy, public outreach, and other measures. The city uses a decentralized model that leverages a mix of municipal resources, NGO leadership, civil society, and cooperation from proud residents and businesses.

As the U.S. Southwest continues to navigate ongoing water crises, several places — including Las Vegas; Orange County, California;, and San Diego — are turning wastewater into drinking water. Their various systems are recycling and treating wastewater as a way to save money and create a reliable supply of drinking water for residents in arid climates. Outreach and education in these communities helped make these systems successful and could be a model for others looking to supplement their traditional water supplies.

Indonesian villagers were experiencing water shortages as natural springs started to dry up in part due to climate change, so they installed infiltration wells to collect and absorb rainwater. Not everyone, at first, wanted to implement the wells on their property, but by 2020, there were 320 infiltration wells in Patemon village. This water conservation project is not being implemented throughout the rest of the country.

Once known for being dirty, the Delaware River is being cleaned up by nonprofits and government entities to the point where they’re encouraging people to swim in it again. The Camden County Municipal Utilities Authority diverted the flow of sewage at 52 municipal plants to a new treatment plant, which has kept 15 million gallons of sewage out of the river each day. While overflows have not been completely eliminated, a national advocacy group even named the Delaware its River of the Year because of its improvements in water quality.
