Wastewater Plant Expansion Funding Gap
Summary
The town will borrow about $96 million to double its wastewater treatment capacity, adding roughly 10,000 dwelling units' worth of capacity — enough for 25,000 to 30,000 more residents. Debt service is expected to be paid by development impact fees, with the town's new Aaa credit rating lowering costs.

Impact analysis
Roughly $96 million in new debt over a 25-year amortization, backed by excise taxes and state shared revenues, paid primarily from impact fees — growth pays for growth, but general funds could be tapped if development slows.
Current and future residents and businesses needing sewer capacity as Marana grows; the town also benefits from lower borrowing costs thanks to its Aaa rating.
If growth stalls, other town revenues could temporarily be loaned to cover debt service instead of going toward services.

Council-Regular Meeting — September 1, 2026
The Water Reclamation Facility Phase II Expansion is now estimated at $80.4 million — well over original estimates. The council shifted up to $4.2 million of water-fund authority to cover the gap, paid by developer impact fees and future debt, not water rates.
