RVT Group’s EnviroHub® Water Treatment Hire Solutions Provide Modular, Site-ready Systems Designed to Manage Water Quality on Site.

It’s a unit used in water treatment systems to store and automatically add treatment chemicals into contaminated water so it can be treated effectively before discharge or further processing. In the RVT Group system, the dosing skid holds chemical reagents and injects them into the water stream as needed to condition the water for solids removal or pH correction.

Under UK legislation, it is an offence to discharge polluting substances into controlled waters without prior approval from the Environment Agency (England and Wales) or Scottish Environment Protection Agency (Scotland). These regulators have considerable powers to prosecute companies that fail to adequately control environmentally harmful materials and processes under the Environmental Permitting Regulations 2010 and the Water Resources Act 1991.

The Environment Agency's Guides titled "Discharges to surface water and groundwater: environmental permits" and "Temporary Dewatering from Excavations to Surface Water" explain when you do and do not need an environmental permit to discharge water to surface water or the ground.

As per the guidance; "You usually need an environmental permit if you discharge liquid or wastewater into surface water".

Ground investigation reports will help you understand the previous use of the land, potential contamination, ground conditions, existing drainage, the presence of water courses etc. so that you can establish a safe and robust water management plan.

Dewatering refers to the process of removing groundwater or surface water from site before construction begins.

EnviroHub kits consisting of settlement tanks, pH treatment and chemical dosing tanks are a popular choice for contractors and are frequently used as construction and ground dewatering systems.

Flocculants and coagulants make up an important part of water treatment systems. They are treatment chemicals used in industrial and construction waste water treatment processes for solids removal, water clarification, precipitation, pH control and dewatering.

Coagulants are used to neutralize the negative electrical charge on particles (colloids), which destabilizes the forces keeping the particles apart. Flocculants, gather the destabilized particles together, causing them to agglomerate and settle out of solution.

In some applications, CO² can be used to neutralise alkaline waters to reach a desired pH for an optimum reaction with the coagulant and flocculant.

Yes, our solutions can be paired with monitoring equipment to give you real-time visibility into water quality, helping you manage performance and document compliance.

Depending on the configuration, the systems can target high pH, suspended solids, and various other site specific pollutants, offering flexible and scalable treatment options.

Yes, by improving water quality and controlling key parameters such as pH and turbidity, our systems support compliance with environmental regulations and help reduce the risk of pollution.

Yes, our tanks and skids are designed for rapid setup and simple integration, allowing your team to start treating water with minimal disruption to operations.

Yes, our modular approach allows the tanks and dosing skids to be configured for a wide range of applications, from construction and civil engineering sites to industrial environments with more complex water profiles.

The dosing skids precisely introduce treatment chemicals, such as flocculants or pH adjusters, to optimise settling, filtration, and overall water quality, ensuring efficient and reliable results.

Our water treatment tanks and dosing skids work together to remove contaminants such as suspended solids, high pH, and chemical pollutants from site water, helping you achieve safe and compliant discharge levels.
