Technical Specialists Are Winning — Both the Backlog and the Deal Sheet

EPA's 2026 SBIR Phase I Solicitation Targets Water Reuse and PFAS Destruction

EPA opened its 2026 Small Business Innovation Research (SBIR) Phase I solicitation on September 24, with applications due November 8.¹ The priority topics are specific and telling: real-time monitoring technology for water reuse systems, and advanced destruction methods for PFAS in wastewater sludge and biosolids — both squarely inside the "physical necessity" category of environmental spending Gaya has been tracking as the more durable half of the sector, distinct from spending tied directly to federal climate mandates.¹

A broader theme is emerging alongside individual rulemakings: according to Capstone Partners' latest Environmental, Health & Safety market update, sector M&A activity has reversed a two-year downtrend, with 61 deals announced or completed year-to-date 2026 — up 15.1% year-over-year — and private-equity participation nearly doubling to nine platform deals.² The report frames the driver as technical specialization: firms that combine monitoring capability (reference-grade instruments plus sensor networks and analytics) with environmental engineering services are commanding the premium, while data centers are singled out as "a meaningful growth vector" tied to advanced ventilation design, air monitoring and emissions verification for hyperscale cooling systems.²

No new EU, UK or China environmental regulatory development was identified specifically within this week's coverage window. One item carried forward from prior issues reaches its deadline immediately after publication: the EU's Empowering Consumers for the Green Transition Directive (EmpCo) becomes binding across all member states on September 27 — tomorrow, as this issue publishes — banning unsubstantiated generic environmental marketing claims absent recognized third-party certification, with penalties of up to 4% of annual turnover.³ This is the last call for any client with EU-facing marketing or packaging claims to have reviewed language before enforcement begins.

None of the three results below were reported inside this week's coverage window — Tetra Tech reported July 29, Jacobs August 4, and Stantec August 12 — but taken together they are the clearest read-through available on demand across environmental engineering and consulting heading into Q4, and none of this data has appeared in a prior ENV Weekly issue.

Jacobs: Data Centers and Semiconductors Now Named Growth Drivers

Jacobs raised full-year guidance for the third consecutive quarter, now targeting adjusted net revenue growth of 9.5%–10.0% and adjusted EPS of $7.20–$7.30.⁴ Within its Infrastructure & Advanced Facilities segment, the company cited the Data Center, Semiconductor, Energy & Power, Transportation and Water sectors as broad-based growth drivers and noted an Engineering News-Record #1 ranking in 18 categories including data centers — though the company's release does not break out data centers as a specific percentage of revenue, a figure sometimes cited in secondary trade coverage that Gaya could not independently confirm.⁴

Tetra Tech: UK Water and US Defense Remediation Carry the Quarter

Tetra Tech's Global Services Group grew 7% year-over-year on water infrastructure and defense-related work, while its WaterNet™ digital platform is now used by 75% of UK utilities against a £2.5 billion UK/Ireland contract capacity and the region's broader £105 billion AMP8 capital program.⁵ US municipal water treatment work grew 5% year-over-year, offsetting declines in flood-protection spending.⁵

Stantec: Water Is Growing Organically at 13%

Stantec's Water business posted 13.0% organic net revenue growth year-to-date, with management pointing to sustained high-single-digit organic growth expectations through year-end on the strength of ongoing Asset Management Program frameworks internationally.⁶ The company also closed its acquisition of Niche in Australia on July 31, adding environmental-services capability in that market.⁶

Willdan's CEO framed the deal as diversifying core markets and broadening commercial and industrial capability, with explicit reference to positioning for "growing demand in energy-efficient data centers" — Mantis already serves data-center, food-and-beverage and healthcare clients.⁷ Earnings accretion is expected in 2027.⁷

Artheon's acquisition of Laberge Group expands its municipal-engineering and grant-funding footprint into the Northeast; Long Point Capital's proposed partnership with WithersRavenel backs growth in state and local government consulting rather than an outright sale; and DLR Group's acquisition of London-based Conran and Partners scales its sustainable-architecture and global design practice.^8,9,10 None of these four deals discloses a purchase price except Willdan/Mantis.

State and local regulators are moving to scrutinize data-center wastewater discharge more closely, and recent enforcement history explains why. In Wyoming, Meta's Cheyenne data center released cooling wastewater containing Cupriavidus gilardii bacteria in early 2026, prompting the state Board of Public Utilities to ban future discharges of that kind to municipal treatment plants.¹¹ In Oregon, Amazon Data Services settled litigation in the Lower Umatilla Basin for $20.5 million over allegations it was discharging tens of millions of gallons of high-nitrate wastewater annually.¹¹ Microsoft's Quincy, Washington facility took a different path, building a $30 million on-site wastewater treatment system for its closed-loop cooling discharge, operational since 2021.¹¹ Communities in Arizona, Wyoming, Utah, Nevada and New Mexico are flagged as particularly sensitive to water-consumption concerns going forward.¹¹

Per contract-tracking coverage, WSP USA was awarded a five-year, approximately $43.4 million IDIQ contract to continue operating CASTNET, the EPA's long-running rural air-quality and atmospheric-deposition monitoring network.¹² Gaya could not independently confirm the exact award value against the underlying federal award record in time for publication; the contract vehicle and incumbent relationship (WSP has held prior CASTNET support contracts) are confirmed.¹²

New York's Environmental Facilities Corporation announced $3 million distributed across 63 wastewater engineering planning grants statewide this month, moving municipal clean-water initiatives toward construction financing.¹³ Individual awards are modest, but the volume — 63 separate municipal engagements from a single state program in one cycle — is a useful reminder of how much recurring, planning-stage engineering demand exists below the headline federal and public-company numbers.
