ManholeMetrics provides a smart sensor network and data platform for wastewater and stormwater infrastructure. It utilizes affordable, durable radar-based level sensors designed for rapid deployment. The platform delivers real-time and predictive insights, issuing alerts for overflows, blockages, and infiltration, thus enabling proactive management of urban water systems.
Founded by Will Dubin around 2020, ManholeMetrics emerged from his background as an Imperial College Civil Engineering Masters graduate. Dubin identified significant strain on urban water networks due to climate change and aging infrastructure. His insight was the critical need for an accessible, scalable monitoring solution to enhance system resilience and operational efficiency.
ManholeMetrics serves cities, utilities, and transport authorities, providing precise network data. The company aims to improve capacity monitoring, optimize capital projects, and refine hydraulic model calibration. Its vision is to foster more resilient, compliant, and cost-effective urban water management, turning data-driven insights into actionable strategies.

ManholeMetrics is an IoT startup founded in 2021 that builds affordable level sensors and a data analytics platform called Porthole to monitor wastewater, sewer, and stormwater collection systems in real time.[1][2][5] It serves municipalities, utilities, and organizations managing these networks, solving problems like flooding, backups, sanitary sewer overflows (SSOs), combined sewer overflows (CSOs), and inflow/infiltration (I&I) through early detection, alerts, and insights for operational, planning, and compliance needs.[1][2] The company has raised over $300K in funding and shows strong growth momentum, with deployments expanding rapidly in 2025 across clients like Columbus Water Works, City of Windsor (ON), Olathe (KS), EBMUD, Toronto Water, Northumbrian Water, Network Rail, and others, alongside milestones like IP68 compliance, accelerator acceptance (ImagineH2O), and new product releases.[3][5]
ManholeMetrics emerged from the need to modernize outdated wastewater management amid climate change, urbanization, and aging infrastructure, which cause frequent incidents like backups and overflows.[2] Founded in July 2021 by Will Dubin in London, UK, the company started as an idea while Dubin was still in university, quickly growing to a team of five with support from Thames Water, multiple awards (including Mayor’s Entrepreneur and Royal Academy of Engineering Enterprise Fellowship), and pilots proving cost-effectiveness.[3][4] Early traction came from leveraging resources like Imperial Enterprise Lab and Geovation hub, leading to rapid evolution into a global player with deployments, certifications (CE, FCC, IC), and an installation app launched by early 2025.[3][5] Recent hires like full-stack engineer Patrick and operations associate Francesca in December 2025 signal further scaling.[5]
ManholeMetrics rides the wave of smart cities and climate-resilient infrastructure, where aging urban wastewater networks face intensified flooding risks from extreme weather and population growth, demanding scalable IoT monitoring.[1][2][3] Its timing aligns with regulatory pushes for environmental compliance (e.g., SSO/CSO reduction) and capital projects needing data-driven calibration, amplified by market forces like low-cost sensor tech and 5G/IoT advancements making mass deployment feasible.[2][5] By enabling utilities to shift from reactive to predictive maintenance, it influences the ecosystem—lowering costs for cash-strapped municipalities, supporting sustainability goals, and setting a model for industrial IoT in rail, energy, and construction sectors as seen in Network Rail adoption.[3][5]
ManholeMetrics is poised for accelerated expansion, building on 2025's deployment surge and hiring to target more U.S./European utilities amid rising climate pressures.[5] Trends like AI-enhanced predictive analytics, regulatory mandates for real-time monitoring, and infrastructure bills (e.g., U.S. IIJA) will fuel growth, potentially evolving it into a platform leader with global API integrations.[1][2] As deployments scale, expect partnerships with hydraulic modeling firms and larger contracts, solidifying its role in preventing urban flooding crises—transforming a 2021 university idea into essential infrastructure tech.
