Washington Update

Negotiations Continue for Infrastructure Legislation as WateReuse Advocates for Water Recycling

President Biden and congressional leaders continued to negotiate an infrastructure package last week. Republican lawmakers indicated a willingness to support as much as $800-900 billion in spending, relative to the President’s $2.25 trillion proposal. Republican leaders had previously proposed $568 billion as their initial counteroffer. The initial Republican proposal included $35 billion for drinking water and wastewater infrastructure and $14 billion for water storage, while the Administration’s plan calls for $111 billion for water systems infrastructure, focusing on resilient systems and providing clean, safe water to all communities. Both sides aim to reach a deal in the coming weeks, though the scope of the bipartisan deal remains murky.

The WateReuse Association continues to work with congressional leaders and champions to advance water reuse policy goals in the legislation. That said, it is possible that a bipartisan package will ultimately be limited in scope to transportation and broadband investments, and exclude most water infrastructure spending. Under that scenario, WateReuse will advocate for a second legislative package to greatly expand investments in water recycling.

Purdue Researchers Develop Energy Efficient Desalination

Purdue University engineers have developed a new approach for reverse osmosis treatment that provides better energy efficiency, longer-lasting equipment, and an ability to process water of a much higher salinity. Called “batch reverse osmosis,” the system processes a set quantity of water at a time rather than keeping a constant flow at high-pressure levels. In research results published in Desalination, researchers indicate that their models offer the lowest energy consumption ever for seawater desalination. Read more.
