10 Best Water Recycling Stocks to Buy

8. DuPont de Nemours, Inc. (NYSE:DD)

Number of Hedge Fund Holders: 35

DuPont de Nemours, Inc. (NYSE:DD) supplies filtration and purification technologies used in wastewater treatment, desalination, and industrial water processing. Demand across these applications gives its water business several avenues for growth.

In Q3 2026, organic water sales increased by low single digits as industrial demand and semiconductor applications offset some Middle Eastern disruption. Excluding that region, growth reached mid-single digits. Management reported roughly 20% growth in semiconductor-related water applications, supported by AI infrastructure investment. Wastewater treatment and specialty filtration also performed well.

DuPont de Nemours, Inc. secured a major containerized desalination project in Europe, the Middle East, and Africa, where its ultrafiltration modules increase drinking-water output within limited space. Such projects offer further growth, although delivery schedules remain uncertain.

Profitability is also improving. Healthcare & Water Technologies increased operating EBITDA by 7% against 4% sales growth. RBC Capital supported this progress on November 5, raising its target to $173 from $160 and maintaining Outperform, citing organic growth and productivity. Our earlier coverage examines the Q1 earnings beat and analyst optimism behind DuPont’s rally.

The remaining hurdle is converting demand into revenue. DuPont de Nemours, Inc. deferred approximately $15 million of Middle Eastern water sales into 2027 despite having the orders in hand. Completing those projects would strengthen growth, but continued disruption could postpone the contribution.

7. TETRA Technologies, Inc. (NYSE:TTI)

Number of Hedge Fund Holders: 35

TETRA Technologies, Inc. (NYSE:TTI) provides water management services to oil and gas producers and is developing desalination technology that could turn produced water into a usable supply for industrial customers.

Its existing business is improving ahead of that opportunity. In Q3 2026, Water & Flowback Services revenue increased 21% year-over-year to $76.1 million, while adjusted EBITDA rose 69% to $12.7 million. International expansion and adoption of its SandStorm sand-removal technology helped lift the segment’s margin by 480 basis points to 16.7%.

Oasis, its desalination platform, could expand the customer base further. Management identified seven prospective projects, including four connected to data centers and their power requirements. Some could initially treat brackish water before switching to produced water, giving customers a potential supply while the reuse market develops. Earlier earnings coverage details the pilot results behind TETRA’s push to turn oilfield wastewater into a new water source.

Commercial timing remains uncertain. Customers must obtain permits, and management has withheld near-term Oasis revenue targets until approvals and contracts advance. Stifel’s September target reduction reflected this limited desalination progress, alongside uncertainty elsewhere in TETRA Technologies, Inc.’s business.

Clear Street upgraded TETRA Technologies, Inc. to Buy with an $11 target on October 6, but its valuation incorporated expected 2028 bromine earnings. That makes execution across several growth projects important. For the water thesis specifically, permits and signed contracts are the next meaningful milestones.
