Water Neutrality and Property Development

In the face of growing environmental challenges, water neutrality has become a hot topic for sustainable development. As the UK strives to meet its housing and infrastructure goals, balancing the demand for water with the limits of supply is becoming increasingly important. Water neutrality ensures that new property developments do not place extra strain on already scarce water resources by offsetting water use in new buildings with reductions elsewhere. This approach helps maintain the balance between urban growth and the protection of vital water supplies.

Water neutrality is particularly important in regions facing water stress, such as the South East of England, where both population growth and climate change are putting additional pressure on the water system. By implementing a water neutrality strategy, developers can continue building new properties without increasing the overall demand for water – a critical step towards a more sustainable future.

What is ‘water neutrality’?

To put it simply, water neutrality means making sure that constructing new homes or buildings to a specified area will not increase the overall amount of water consumption within that area.

Imagine if you wanted to add new homes to a neighbourhood. Normally, this would increase the total amount of amount of water used by that neighbourhood. But with a water neutrality strategy, developers find ways to save water elsewhere, like fixing leaks or using water-saving technology, so the overall water use stays the same. It’s a way to grow without using more water, which is essential as we face water shortages in many parts of the country.

In practice, this could mean installing water-efficient appliances in new homes or rainwater harvesting systems in industrial buildings, plus implementing initiatives to encourage existing water users in the area to reduce their water consumption. This way, the total water use doesn’t increase, even with new development.

How is global warming affecting our water supply?

One of the key reasons water neutrality has gained attention is due to the growing impact of global warming on water availability.

Warmer air holds more moisture, leading to heavier and more intense rainfall. According to the Met Office, each 1°C rise in global temperature allows the atmosphere to retain 7% more water, leading to heavier rain. Since 1850, the average annual increase in Earth’s temperature has been 0.06° C, for a cumulative total of around 1.1°C.

As a consequence, the UK has experienced a marked increase in rainfall in recent years. The period from 2011 to 2020 was 9% wetter than from 1961 to 1990. Since records began in 1862, six of the eight wettest years for the UK have occurred since 1998.

Although more rain seems like a solution to the water scarcity, the reality is that it causes more issues. A heated, energised atmosphere results in shorter, more intense rainstorms, making it harder to capture and store the water for future use. Rather than replenishing reservoirs or groundwater supplies, much of the excess runs off into rivers and seas.

What is the effect of population increases?

The situation is made more complicated by population growth. In 1898, the UK population was approximately 40 million. According to ONS official population forecasts, by 2026 it will reach 70 million.

As more people move into a given area, the demand for water increases, but the supply remains limited. Historically, the South East of England including London has been one of the UK’s most prosperous regions; this, combined with population growth, is stretching the available water resources extremely thin.

Implementing a water neutrality strategy offers a solution by balancing new development with water-saving measures, ensuring that population growth doesn’t lead to water shortages.

How is water neutrality implemented?

The legislative framework for enforcing water neutrality in the UK primarily revolves around regional and local planning policies, rather than national legislation.

While there is no specific national law mandating water neutrality, local authorities in water-stressed areas, particularly in the South East of England, have begun incorporating water neutrality requirements into the planning process. This is often done in collaboration with water companies and environmental agencies to ensure new developments do not exacerbate existing water shortages.

Key frameworks include the Environment Agency’s guidance on water demand management and regional water resource management plans, which encourage developers to adopt water-saving measures and achieve water neutrality in new projects.

What are the potential solutions?

Achieving water neutrality involves more than just reducing water use in new buildings. Developers can adopt a range of solutions to meet water neutrality targets, ensuring that their projects are sustainable for the long term.

New developments

One solution is to integrate water-efficient technologies into new developments. These could include low-flow taps, dual-flush toilets, and appliances that use less water. Rainwater harvesting systems, which collect and store rainwater for reuse, can also be a key feature in reducing water consumption. Greywater recycling systems, which reuse water from sinks, baths, and washing machines for non-drinking purposes, are another option.

Older properties

Developers can also collaborate with local authorities and water companies to improve water efficiency in existing properties. Retrofitting older buildings with water-saving fixtures, reducing leaks in the water supply system, and encouraging people to adopt water-efficient practices can offset the increased demand from new developments. These measures not only contribute to achieving water neutrality but also help communities become more resilient to water shortages.

Long term planning

Moreover, long-term planning and collaboration are essential. Developers can work with planners and water authorities to identify water-stressed areas and prioritise water neutrality efforts where they are most needed. By adopting a comprehensive approach that combines technological innovation with broader water management strategies, developers can help ensure the sustainable use of water resources.

What is Panattoni doing to enhance water neutrality?

As the largest developer of industrial warehouses in the UK, Panattoni is committed to incorporating water neutrality principles into its projects, ensuring that new developments do not increase water demand in already stressed regions.

Panattoni’s latest warehouses, such as their industrial units in Nottingham, are equipped with advanced water-saving systems, including rainwater harvesting and greywater recycling, which significantly reduce water use. The company also prioritises leak detection and repair, helping to conserve water throughout its properties. In addition, stormwater attenuation systems capture the rainfall from storms, releasing it slowly into local water courses, and increasing the absorption into local groundwater systems.

These measures not only align with the goal of water neutrality but also demonstrate Panattoni’s dedication to environmental sustainability. By prioritising water neutrality, Panattoni is setting a standard for industrial property development that balances economic growth with environmental responsibility. The company’s focus on reducing water consumption while continuing to deliver vital infrastructure reflects its commitment to long-term sustainability and its leadership in the logistics industry.

Looking towards a sustainable future

Achieving water neutrality represents a crucial step toward sustainable growth in the UK, particularly as the nation grapples with the twin challenges of climate change and population growth. By ensuring that new developments do not increase overall water use, developers can help protect the country’s water resources for future generations.

Panattoni UK’s leadership in adopting water-neutral practices is a clear example of how adopting best practice actively shapes a more sustainable water supply. As the UK continues to build for the future, the integration of water neutrality into development strategies will be key to managing water stress and ensuring that growth does not come at the expense of the environment.
