On this project, biodegradable silt mats have been placed across the swales that traverse the site to trap silt run-off and prevent it polluting nearby watercourses. The silt mats are manufactured from coir, which is a natural material made from coconut fibres that will biodegrade over time. Natural vegetation can grow through the silt mats, helping to stabilise the swales…
This contractor is using a biodigester solution (bacteria) that can clean plant nappies that are contaminate with oils, HVO or other hydrocarbon products The traditional approach would be to use plant nappies or pads that are usually single use, or none effective, and to then dispose of the item as a waste, most likely classed as hazardous. This method aims…
The Project Team has introduced a creative and proactive approach to managing potential fuel spills in their refuelling storage area. The team has constructed peat bunding around the fuel storage and incorporated a new product called Premium ProCleanSorb Granules from Pro-Earth within the bunding. The granules are a natural, renewable, sustainable source made from Peat Sphagnum Moss. These hydrophobic granules…
Water monitoring for suspended solids and basic chemistry is common practice across construction but due to sensitivity of the environment (working above source protection zone 1), this contractor implemented a detailed water monitoring plan to analyse a larger suite of physical and chemical parameters (>50 individual parameters per sample) than required by environmental consents. Almost 8000 samples have been collected…
This project’s marine licence requires site to stop construction spills from entering the marine environment. The site were originally due to install a large filter drain system and collection ponds to process all run off from the existing platform. This would involve excavation within the Saltmarsh environment, potentially damaging the SSSI location and require 24/7 pumping system to be on…
SlurrySep is a line of reactive separating agents composed of minerals, pH adjusting components, and polymers. They are specially blended high efficiency formulas designed to remove high levels of suspended solids from wastewaters leaving clean water for compliant discharge or reuse. Remaining sludge is non-leachable and will pass Toxicity Characteristic Leaching Procedure (TCLP). This is a cost-effective waste treatment process…
This fuel digester encapsulates oil particles and prevents them from sticking to and landing on shorelines, beaches, rocks, plants and animals. It is alsp pH-neutral and dermatologically safe. When used on waterways, the Bioversal-oil-water mixture remains on the surface and the bio-activator contained in Bioversal ensures high accelerated biological degradation of the remaining oil residue and leaves water and CO2…
Biobrane Silt Pockets are designed to trap eroded material which encourages settlement of silt. On this project, they have been used as a type of check dam which require no-dig to control surface erosion from sheet run off and the migration of silt off site. As the silt pockets fill with water and trap silt, they create a sediment trap…
During the early stages of this project, it became evident that there was a high ground water level and this would massively effect programme and increase costs. With the excavation of the pools that they were due to carry out, they were aware these excavations would quite quickly fill up with ground water which left them with two options available…
Following the enabling works to the site, it was discovered that the site was accumulating surface water, which was not naturally draining away due to ground conditions. In collaboration with SEPA, a system was designed to drain away all surface water on site into the drainage network. The system developed is an innovative environmentally friendly system, the drainage is all…
Costain and ALS (laboratories) are working together on a new software suite for onsite compliance testing of water arising from excavations. The app based sample recording and submitting process ensures that samples are correctly logged to the sample point (can be used to check sampling has been undertaken correctly if results are not as expected and that sample is from…
Reusable temporary sustainable drainage systems (SUDS) are used to ensure the project are not causing any escape of surface water from the perimeter of the site. The materials used, will allow the rings to be lifted out and used on future projects. Therefore, eliminating the requirement to keep on buying new materials. The SUDS area is very discreet and still…
To improve surface water management on Beinn an Tuirc Windfarm Phase 3, a large lagoon was built to collect all sludge from Sustainable Drainage Systems (SuDS) ponds across the entire site. To prevent any potential leaks and ground water contamination, the lagoon was lined with impermeable material. After the silt has settled, the lagoon is emptied of treated, clean water…
A large temporary car park has been formed on the footprint of what will be a sports pitch area. It is designed to be self draining as it is constructed using a gravel filled grid system, set at a level to allow it to be top soiled over as part of the permanent works. This removes the need for double…
The Morgan Sindall Volker Fitzpatrick JV has installed a sustainable drainage system (SuDS) to capture and treat both domestic and trade effluent from the main project offices and car park at their Barking Riverside Extension Project. The system is installed south of the office complex and is comprised of a Kingspan BioFicient Klargester for the treatment of the domestic effluent…
