The City of Saint Paul supports developments like Allianz Field to ensure our city works for our families,
businesses, and cultural communies for years to come. Key to that vision is a bold commitment to
sustainability and green infrastructure that will support the long-term health of our community and
environment.
At the Allianz Field stadium site, the City of Saint Paul has developed landmark clean water infrastructure,
which will recycle more than 2 million gallons of rainwater every year. This unique system, the largest and
smartest of its kind, will be used to irrigate trees and grass across the site, and to serve future developments
around the stadium.

The City of Saint Paul’s Rainwater Reuse System for Snelling-Midway
When it rains, water is collected from the roof of Allianz Field,
and other new roofs on the stadium site, and ows into the
new rainwater reuse system, where it is stored in a central tank
which can hold more than 675,000 gallons of water.
From here, the water is processed through a smart
hub that analyses and cleans the water. This smart
hub, designed by a team of experts led by the City of Saint
Paul and built by local contractors, can even read weather
forecasts to predict rainfall and adjust water levels
accordingly.
Aer being cleaned in the smart hub, the water is
sent out to irrigate the 150,000 square feet of
public open space around the stadium, including the 20,500
square feet of grass on the Great Lawn and the 192 mature
trees which have been planted across the site.

This new clean water infrastructure will serve not
only Allianz Field, but also future developments
in the Midway Development District. This will
address a potenally expensive challenge for area
developments, eliminang the need for buildings
to construct individual stormwater tanks on their
properes. This will simplify and streamline the
construcon process for new developments, and
present new opportunies and greater exibility
for builders.
Connecng new developments with the landmark
water system will also provide these businesses
with a source of ltered water for uses such as
laundry, irrigaon, or restroom ushing.
The City is exploring opportunies to generate
funding for ongoing construcon and
maintenance costs based on assessments to
new developments on the site, making it both
environmentally and economically sustainable for
area businesses and the City of Saint Paul.
