The Path to Drawdown: Water Distribution Efficiency
Water utilities are among the largest consumers of electricity globally. They’re responsible for about 1% of total electricity use in the world. Up to 80% of that energy is used for pumping water alone. But ~35% of that water is wasted through pipe leakage, meter error, and unauthorized consumption. This all adds up, dramatically reducing the supply of water over time and producing unnecessary emissions to generate the energy used to pump more water.
Water efficiency solutions can minimize this leakage. Pressure management and active leak detection are two important solutions. Pressure management involves installing pressure valves at water inlets and outlets to better monitor water flow and pressures, and leads to reductions in pipe bursts and leaks. Solving leaks takes substantial investment, but it’s the cheapest way to source new supply, serve growing urban populations, and reduce emissions.
Project Drawdown estimates that, if 38-47% of the global water distribution network can adopt these solutions, it could reduce CO2e emissions by 0.66 - 0.94 gigatons between 2020 and 2050. That’s an emissions reduction equivalent to taking close to 204.5 million passenger vehicles off the road for one year.
Watts Water Technologies, Inc. (stock ticker: WTS) supplies products and solutions that manage and conserve the flow of fluids and energy for the residential and commercial buildings. Headquartered in North Andover, Massachusetts, they operates in more than 24 countries..
WTS’s Role in Drawdown
Watts Water Technologies’ broad range of products can be classified into four product lines (p. 4-5). Three of these product lines contribute to the Drawdown solution of improving water distribution:
- Their residential and commercial flow control products consist of products that are typically sold into plumbing and hot water applications. Things like backflow preventers, water pressure regulators, temperature and pressure relief valves, and thermostatic mixing valves.
- Drainage and water re-use products include drainage products and engineered rain water harvesting solutions for commercial, industrial, marine and residential applications.
- Water quality products include point-of-use and point-of-entry water filtration, conditioning and scale prevention systems and monitoring and metering products.
WTS: What We Like
We applaud Watts for their track record in reducing their environmental and carbon footprint over the last several years. These achievements include:
- Reducing water usage by 63 million liters in 2020
- Reducing CO2 emissions by 4,000 metric tons in 2020. This was the latest accomplishment in a 16% reduction (p. 39) in scope 1 and 2 emissions combined since 2014.
- Purchasing wind RECs to offset emissions from 100 GWh of electricity (p. 34) for the next 4 years
On top of these steps, Watts has set a target to reduce annual GHG emission intensity by 3% (p. 34) with 2018 as the baseline year. They’ve also committed (p. 30) to reduce annual water intensity by 3%
