The Environment Secretary warns that contractors who breach their permit conditions, illegally discharge water, or damage precious habitats in any way, “will pay”.
17th January 2024As construction managers, environmental sustainability is always at the forefront of our mind, albeit planning ways to reduce fossil fuel consumption or adapting our processes to avoid air, ground or water pollution.
One topic that is increasingly being highlighted by authorities and the media, is water pollution. In fact, water pollution has become such a hot topic, that the financial penalty for companies who pollute the environment is no-longer capped!
In December 2023, the Environment Agency were awarded new powers to issue fines that are proportionate to the size of the company and the nature of the offence - with no upper limit. Furthermore, if you are found to be responsible, you could face up to 5 years in prison.
The Environment Secretary warned that contractors who breach their permit conditions, illegally discharge water, or damage precious habitats in any way, “will pay”.
This forms part of the UK Government’s plan to ensure there is more investment, stronger regulation and tougher enforcement across the water system.
Rest assured. We have created a 5-step guide to help you manage water effectively and avoid fines from the Environment Agency.
Step 1: Understand your construction site.
It’s a good idea to start with a ground investigation report. You may think that you know your site, but do you have all the information you need to create a fully compliant water management plan? For example, a ground investigation report might reveal:
Step 2: Understand the regulatory requirements for water treatment & discharge.
It is usual for sites to have excess water that needs to be discharged, but as per the Environmental Permitting Regulations (2010) and the Water Resources Act (1991), it is an offence to discharge water without prior approval from regulators such as the Environment Agency (England and Wales) and Scottish Environment Protection Agency (Scotland).
Whilst it is safe to assume that you will need an environmental permit for discharging water, there are some exceptions, therefore The Environment Agency have produced a document titled ‘Temporary Dewatering from Excavations to Surface Water’ which outlines exactly when you do not require a water discharge permit.
Prior to application, it is important to identify and consult with the relevant authoritative bodies that may have direct say in your environmental arrangements (EA / SEPA / Water board / Local Council), otherwise your application may be rejected.
Also, be aware, applications usually take several months to be approved, so it is worth assessing your requirements early and submitting an application form as soon as possible. Please note, you will also be expected to have an Environmental Management System (EMS) in place.
See the Government’s Pollution Prevention for Business guidance notes for more information.
Step 3 & 4: Identify site activities, and Assess the risk of contaminants/ pollutants.
The identification of environmental risks will form part of your Environmental Management System (EMS). Here are some typical site activities you might need to consider:
Step 5: Create an action plan for managing the contaminated water.
The systems you put in place to reduce the risk of water pollution, will also need to be detailed in your Environmental Management System (EMS). Depending on the volume of water on site, you may need temporary drainage systems, pumps for dewatering, and temporary water holding areas. You then need to consider how you are going to remove silt, suspended solids, oil, hydrocarbons, and treat pH imbalance.
For example, if you are holding a large volume of water that has been contaminated with suspended solids and has a pH imbalance, you could:
RVT also offer in-stream water monitors so that you can check the turbidity, temperature and pH of any water that is discharged to surface watercourses (Eg, into a stream). This will not only give the site team peace of mind, but the data can also be used as evidence of compliance should any questions arise from environmental authorities.
As mentioned earlier, environmental permits for discharging water can take a long time to be granted, therefore you might want to consider discharging treated water to a sewer under a trade effluent license, rather than discharging it into a surface water course.
This is just one example of how an EnviroHub® system can be used to manage contaminated water on site. RVT also offer an EnviroHub® Concrete Washout System which enables silt to be removed through a geotextile bag, before reducing the alkalinity in a treatment tank.
