David Meyer (né Taylor)


My research focuses on urban water distribution infrastructure, and specifically how this infrastructure behaves in Mega Cities in the Global South. Projects include new ways of understanding, sensing, managing, and modelling water networks, especially networks that turn on and off frequently. Such intermittent water systems affect one billion people!

Additional projects invent new mechanisms and new sensors that change the efficacy of water and sanitation globally.

Professor David Meyer (né Taylor) completed his PhD and M.Sc. in Mechanical Engineering at MIT, is an alumnus of Engineering Science (Energy Option) at U of T. Additionally, David has worked for Engineers Without Borders (EWB) in Ghana and for HydraTek in Toronto.

Current Students

Samantha LeValley: Sami is a PhD Student studying equity among improved rural water supplies in the Global South. In 2019, she completed her BS in Mechanical Engineering at the University of Massachusetts Amherst. In 2021, under Prof. Meyer's supervision, she completed her MASc in Civil Engineering at UofT with a Collaborative Specialization in Global Health. Her MASc research explored ways to mathematically model diarrheal defecation inside the body for the Sensing Health In Toilets (SHIT) initiative.




Gabrielle Migliato Marega: Gabrielle Marega is a second-year PhD student researching how to expand urban sanitation infrastructure in low and middle-income countries to achieve universal and equitable access to safely managed sanitation services. Previously, she worked as an intern at Suez and focused on the drinking water treatment process. She holds a MASc in Sanitation and Hydraulics Engineering from the University of Sao Paulo, a MA in General Engineering from CentraleSupelec (Paris-Saclay University), and a BASc in Civil Engineering from the University of Sao Paulo.



Omar Abdelazeem: Omar is a MASc student interested in providing safe water supply to disadvantaged populations. He is studying intermittent water supply networks, specifically models that help in understanding their behaviour. Omar graduated in 2021 from the University of Science & Technology at Zewail City with a BSc degree in Environmental Engineering.




Hamidreza Mohabbat The main focus on Hamid’s research is modelling intermittent water supply (IWS) networks. His work tries to reduce the complexity of IWS networks to shed light on the barriers of realizing continuous water supply (CWS) in the Global South. Before coming to UofT, Hamid completed his B.Sc in Civil Engineering at the University of Tehran, Iran.

Previous Students

Negin Ahadzadeh: Negin Ahadzadeh graduated with her MASc in 2021. She is primarily interested in providing safe drinking water to underprivileged populations. Her research explored the equity implications of design practices and operational strategies in intermittent water supplies. Prior to her studies at UofT, Negin worked on modelling transient flow during filling a pipe and designing hydraulic structures of desalination plants. She holds an MA in Water and Hydraulic Structures Engineering from the University of Tehran and a BA in Civil Engineering from K. N. Toosi University of Technology.

Consumer pumps not the worst of Delhi’s water woes

First neighbourhood-scale study of home water pumps shows that they decrease water pressure moderately, but have minimal effect on average water quality    Household water pumps are a quirky feature of many urban water systems around the world. Utility operators hate them, and in many places they have been made illegal, yet their use remains widespread. A new study authored by Professor David Meyer (CivMin, CGEN) looks at […]
