Virginia Beach, VA to transform municipal golf course into stormwater mitigation hub
The City of Virginia Beach has developed a plan that explores using the approximately 121-acre, City-owned Bow Creek Golf Course for flood mitigation. The vision for the project is to convert the land use from a golf course to a multi-faceted facility that will provide significant stormwater storage to mitigate flooding and restore natural systems while still providing active and passive recreational opportunities.

Alexandria, VA to retrofit hundreds of manhole covers to slow stormwater runoff flows
The City of Alexandria is directing $750,000 toward a project that involves placing stainless steel inserts on 870 manhole covers to slow the rate at which stormwater overflows into the city's sanitation system during periods of heavy rainfall. The city has separate systems for stormwater and sanitation, but the latter serves as an overflow for excess precipitation and the setup can cause untreated wastewater to back up in residents' homes.

Fairhope, AL enhances water resiliency with innovative utility interconnection
The City of Fairhope is partnering with neighboring Daphne Utilities to increase Fairhope Utility's capacity by 500,000 gallons of water in the event of an emergency. By interconnecting water systems, Fairhope ensures a reliable supply of water during emergencies.

Blacktown, NSW develops first-in-Australia program for Water Sensitive Urban Design compliance
Blacktown's long-standing inspection program proved ineffective at finding mismanaged WSUD device use. The council piloted a new program whereby 20 randomly chosen properties were required to report on the conditions of 337 WSUD devices. This pilot included the development of an education toolkit on legal requirements and device maintenance. Local officials anticipated reductions in pollutants entering waterways thanks to well-maintained biofilters, rainwater tanks, and litter traps.

City of Cape Town, WC improves sewer overflow response times with Reactive Incident Management app
Residents encountering wastewater overflows and water line breaks report issues through the RIMA. This mobile app built with SAP supports location tagging, photo uploads, and incident comments. Sewer response teams use RIMA to update repair progress and issue alerts to community members. Cape Town commissioned the RIMA's development, purchased 23 jet-vac vehicles, and created eight rapid-response teams for comprehensive responses to water and sewer issues.

Maastricht, LI combines LiDAR and SLAM technology for smarter sewer mapping and management
Municipal officials and project partner HaDennis developed a 3D mapping system for public sewers. Scanners deployed at access points capture images of surrounding sewers in minutes. Images and cross-sections are turned into a city-wide map of current conditions useful for maintenance plans. This process is inexpensive, keeps field workers above ground, and produces comprehensive maps not possible with past inspection methods.

Santa Monica, CA puts stormwater to better use with its Sustainable Water Infrastructure Project
SWIP connects a stormwater harvesting tank to an advanced water treatment system under a public parking lot. This system can treat up to one million gallons of water each day and store up to 1.5 million gallons. Stormwater and runoff treated at SWIP are sent for use in irrigation, aquifer recharging, and toilet flushing. Santa Monica diverts 100 million gallons of untreated water from the bay each year and produces 10% of its annual water supply with SWIP.

Buffalo, NY prevents sewer overflows during storms with the Wastewater Network Optimization System
Xylem's platform collects data from sensors throughout the city's sewer system. Machine learning processes result in predictions about potential overflows during heavy rains. This system automatically channels water into sewer pipes with available capacity, thus preventing wastewater from entering local waterways. The Buffalo Sewer Authority did not need to add new infrastructure for the project and can scale up the platform's use for future system extensions.

Darwin, NT opens Australian-first wastewater treatment process focused on PFAS removal from leachate
A Low-Energy Evaporative Fractionation (LEEF) system was added to the Shoal Bay Waste Management Facility. LEEF removes poly-fluoroalkyl substances (PFAS) from landfill leachate without additional chemicals, thus preventing harmful runoff. This process can eliminate up to 99% of PFAS from leachate. The facility also features a wetland evaporation system for the removal of ammonia and other contaminants. Local officials estimate a processing capacity of 50 megaliters per year for the new system.

Apeldoorn, GE adopts new technologies for emission-free and digitized sewer maintenance
Repair teams use BAM Infra electrical excavators and compactors that eliminate noxious fumes created by diesel-powered machinery. Apeldoorn worked with The People Group on a 3D scanning pilot for sewer surveillance. The scanning system produces accurate images in minutes without lengthy road closures. A BAM Infra reporting system enables predictions of future maintenance needs based on work order response times and system data.

Prospect, SA adopts Water Sensitive Urban Design features for better management of water supplies
Prospect pursued WSUD principles to reduce flooding, naturally filter water pollutants, and support local wildlife. Council officials installed 80 TREENET inlets on roadside verges with irrigation to nearby trees. Additional features like the permeable pavement at Devonport Terrace and raingardens on select streets further Prospect's WSUD goals. Passersby learn more about how each feature functions by scanning QR codes on adjacent signs.

Vaughan, ON experiments with Ioticiti system for automated stormwater pond monitoring
The Public Works team selected 10 ponds across the city's five wards for a one-year pilot. Sensors gather real-time data on metrics like salinity, water temperature, dissolved solids, and oxygen reduction potential. The Ioticiti system generates predictive analytics for proactive decisions on Vaughan's stormwater treatment system. City officials use reports from the automated system to inform infrastructure repairs and flood mitigation efforts.
