Sustainability Problem(s): Water, Safety

A growing challenge as storms become more intensely localized and the adage ‘when it rains it pours’ becomes more literal is the issue of what to do with all that water in an urban space. In nature, the water is efficiently absorbed into soil and supports trees and other flora. However in a city, the lack of these trees and soil is felt in two ways: first, the rain water has nowhere to be absorbed into and can result in flooding and contamination of the city’s water supply, and second, all that water can cause serious damage to ‘gray’ infrastructure that isn’t designed to handle a sudden deluge – things like streets, drainage pipes, and sidewalks.

This is where Chicago’s new initiative, the ‘Smart Green Infrastructure Monitoring’ (SGIM) project steps in:

Summary of SGIM

  • Utilizing IoT technology, SGIM looks to track rainfall conditions on Chicago’s streets. In addition to total rain, it also tracks thinks like temperature, moisture, air pressure, and other weather indicators.
  • SGIM is in beta right now, being tested in three locations. It is being tested in conjunction with green infrastructure, such as plant banks, and porous water-absorbing roads.
  • The goal of the sensors would be to best understand where changes are needed in Chicago’s water management infrastructure – sensors don’t absorb water, but they help understand where the problems are and how much infrastructure change is needed.
  • Chicago actually has a strong record of utilizing IoT to make the city ‘smarter’, and SGIM falls within the logic of their larger city-wide ‘Array-of-Things’ plan for a smartly monitored city.

Stakeholders

1 – City Digital, developers of SGIM

2 – City of Chicago policymakers, specifically their wastewater treatment plan executors, and their Array-of-Things project leaders.

3 – Citizens of Chicago who’s businesses and homes would be affected by wastewater

4 – Green Infrastructure and SGIM sensor builders and installers.

Three Deployment Steps

First, continue with the testing phase and make sure the project is working as desired

Second, establish a broader installation plan with the office of the city of Chicago

Third, engage manufacturers, contractors, and wastewater managers to produce, install, and use the data.

BaySeparator: Stormwater Treatment

The problem

Storm water is one of the main causes of pollution in cities. All the water runoff that is produced accumulates waste and pollutants throughout the city and is finally poured into rivers and water bodies, affecting environments and natural resources that people depend on.

The technology

The BaySeparator is a water treatment system that treats runoff throughout entire storms, no matter their intensity and duration.

In the following link it is explained how it works with different storm intensities:

The stakeholders

  • Municipalities
  • City governments
  • Water treatment institutions
  • Citizens

Deployment

BaySaver Techonogies Inc. is a company that designs and manufactures stormwater treatment products. They created the BaySeparator in order to improve older systems that treated only the first flush of runoff. The idea was to create a new technology able to treat the stormwater throughout the entire storm.
