Project title: The impact of nutrient neutrality requirements in the UK housing projects
Project Lead: Dr Hong Xiao
Project ID: 09 - 46543366
Project description:
The UK has been experiencing chronic housing shortage for decades and the new Labour government has promised to build 1.5 million new houses by the end of this parliament. This is a very challenging target. To complicate the situation, nutrient neutrality regulations, aimed at reducing excess nitrates and phosphates in English water bodies, have imposed significant challenges for housing developers. Nutrients aid the excessive growth of algae which then impacts on ecosystems and wildlife. To better protect the environment, the Levelling-Up and Regeneration Act and Natural England require authorities and developers propose and demonstrate upfront solutions to mitigate any additional nutrient run-off from both stormwater and increased foul waste to the water bodies.
Sustainable Urban Drainage Methods (commonly known as SuDS) has been widely used for surface water management because they work well at eradicating a number of contaminates, treating polluted runoff and creating biodiversity. Commonly used SuDS include wetlands, retention basins, swales, adapted landscape features (such as tree pits and rainwater gardens) and more manufactured / engineered options (such as oil separators, permeable paving and media filters). But these solutions either tend to be expensive, or if not expensive, not fully encompassing to the issue, too land hunger, or restrictive on when and where they can be utilised or are not yet widely known and deployed in the UK, creating a knowledge and skill gap in build and delivery. Furthermore, foul water / waste entering public network and treatment plants are restricted or prevented. Developers can opt through a credit scheme for mitigation off-site such as the development of a woodland or contribution to treatment of an agricultural field, but this costs money and needs further approvals, consideration and government input to confirm available sites.
There is a lack of consistency, understanding and innovation to resolve the unlocking of housing development alongside the wider water pollution issue. It is estimated that the cost of these methods will increase the price of per home £3,000–10,000, plus ongoing maintenance costs. This results in substantial financial and operational burdens to both the developers and home buyers, causing a huge number of prospective development sites being delayed or put on hold.
This research aims to understand the inter-connected issues in the life-cycle of a housing project in terms of nutrient neutrality requirements and develop a strategy to help housing developers to better navigate the planning process and make an informed decision on the cost-effective mitigation measures to protect the water quality of the rivers and ecosystems.
Anticipated findings and contributions to knowledge:
The implications of nutrient neutrality requirements are acute to housing developers who normally operate with a very tight margin, and the additional costs for compliance are a significant burden. These costs are often passed down to the home buyers, contributing to higher house prices in an already strained housing market. The time required to navigate the planning and regulatory approval process, often delayed by nutrient neutrality considerations, can lead to increased holding costs and financial strain for housing developers. This uncertainty makes it difficult for the housing developers to plan effectively, secure financing and maintain a competitive position in the market.
This research aims to investigate all the inter-connected issues from the nutrient neutrality requirements in the life-cycle of a housing project and develop a cost-effective strategy of mitigating nutrient neutrality. This will help the government and local authorities to better understand the practical implications from the government’s relevant acts and planning regulations so they can provide workable guidance to implementing environment protection laws. The research findings will also help housing developers to effectively navigate the nutrient neutrality requirements during the project appraisal and planning application, select and implement cost-effective nutrient mitigation measures during the design and construction stages, and boost their output of affordable and sustainable houses to meet the market demand. This will also provide a blueprint for tackling other environmental issues such as flooding risk management in housing projects in the UK and beyond.
