12 Ways the Water Industry Is Reducing its Environmental Impact
Jul 24 2021
As the provider of water to 28 million homes across the UK, the British water industry has an understandably large environmental impact. It is the fourth biggest emitter of greenhouse gases in the country, while leaks, spillages and other unplanned discharge incidents can see rivers, lakes and waterways become contaminated with raw sewage on occasion.
However, the industry is very much aware of both its impacts in the past and present and its responsibilities in the future. With that in mind, it published a road map to achieving net-zero carbon emissions by 2030 in November last year, which is a full two decades ahead of the UK government’s legally binding target. Successful attainment of the goal will require the optimisation of existing processes, a transition to cleaner forms of energy generation and the adoption of technologies capable of enabling net-zero emissions.
The progress made thus far
Already, the water industry has made sizable strides towards improving its environmental performance. Between 2011 and 2018, for example, the sector saw a reduction in its greenhouse gas emissions of 45%. Nonetheless, it was still responsible for 2.4 million tonnes of carbon emissions in 2019, indicating that there is a long road ahead before it reaches a net-zero state of affairs.
Similarly, tighter regulation of the industry and enhanced water monitoring equipment have contributed to fewer environmental incidents with regard to water pollution. In 2013, for example, saw water companies experience three series pollution events and 83 minor events for every 10,000km of pipeline. By the following year, those figures had fallen to two major incidents and 71 less serious ones per 10,000km, indicating that the sector is on the right path in terms of the reducing the frequency of such undesirable outcomes.
12 actions being taken now and in the future
Shortly before the UK government announced its commitment to becoming net-zero by 2050, the water industry brought forward its own target by 20 years. To achieve that ambitious goal, it has implemented (or plans to implement) the following steps:
- Restoring original forested areas and improving natural wildlife habitats to serve as sources of carbon capture
- Supplementing those areas by planting 11 million additional trees in England by 2030
- Reducing water leakage rates threefold by 2030
- Reducing the energy needed to operate the industry’s infrastructure
- Encouraging individual citizens to curb their water consumption by 20% by 2050
- Contributing to the “Refill Campaign”, which will promote the practice of refilling old water bottles rather than buying new ones
- Slashing the amount of carbon, methane and other greenhouse gases produced by wastewater treatment facilities
- Optimising energy efficiency across the industry
- Installing more sector-owned renewables such as solar farms and anaerobic digestion plants
- Supplementing that energy with the purchase of other green forms of power, such as biomass and wind
- Sharing biogas with other industries to provide holistically sustainable opportunities
- Transitioning from conventional combustion engine vehicles to electric, hydrogen and vegetable oil-powered alternatives
These aims were expanded upon in the recently published road map to a net-zero industry. Individual water companies are now expected to use that road map as a blueprint for devising their own plans, which are to be published by the end of July 2021.
