Peak Associates work with a wide range of clients from privately owned companies, local authorities to multinational organisations operating in the UK. These include:
Below are some typical projects completed by Peak Associates, If you have any questions with regards to our past and present projects please contact us.

Contaminated Land Remediation Scheme

The client's site is situated on a railway embankment above a residential property. The client lost somewhere between 10 and 20 Tonnes of 48% strength Caustic Soda from one of it storage tanks, which then entered the garden of the neighbouring property. In addition to destroying the garden and killing a number of trees some of the material entered land drains and was discharged to a river nearby.

Having been instructed by loss adjusters acting for the Company we have in the last two years:

- Confirmed that losses of chemicals into the neighbours land had been ongoing for several years.

- Negotiated a remediation strategy with the regulators (Environment Agency and Local Council).

- Undertaken these negotiations in a manner such that the client has not been prosecuted for the pollution of controlled waters or had the site designated as 'contaminated land'.

- Assisted with the negotiation of the settlement of the civil claim by the neighbour.

- Managed the remediation contract and validated the completed scheme. This has involved the installation of a permanent barrier between the clients site and the neighbouring land.

Due Diligence Audit for a Manufacturing Site in South East England

This audit was carried out on behalf of the potential purchaser of the site. The site was in an industrial area and the processes included di-isocyanate processes. The purchaser had significant concerns over the potential contamination of the site, problems with decommissioning of an existing plant, asbestos issues and compliance with legislation.

The audit demonstrated that the site was fully compliant with all of the legislative requirements and that an asbestos management plan had been instigated with all recommendations of the asbestos surveyor carried out. The plant decommissioning was also carried out with all due regard for potential contamination of land and controlled waters. However, the audit did reveal that the site was on an area of potentially contaminated land, but the Local Authority could not confirm at the time whether this site would be included on its register of contaminated sites.

A further intrusive investigation was therefore commissioned and this demonstrated that, although there was some limited contamination of the site, the presence of the overlying concrete (up to 3 metres thick) prevented any mobilisation of this contamination or direct access to the site workforce.

The sale subsequently went ahead.

Sizing and Installation of Effluent Treatment Systems for a major UK airport

Work for this current client has involved the plant installation and all aspects of performance monitoring, sizing and remedial works for the large number (>40) of domestic properties owned by the airport.

Work undertaken has included determining the route and connections of surface water and foul drainage to surrounding properties, and designing appropriate modifications and alterations for these connections. ecommendations for differing modes of discharge, such as outfall structures to meet Environment Agency regulations and soakaway schemes with initial percolation tests to check suitability, have also been addressed. The work includes supervising of contractors to carry out installations as per written instructions with new appropriately sized plants.

Once remedial work is complete, Peak secure any consent and check the effectiveness of the plant and subsequent effluent quality through a thorough inspection and monitoring service. This allows for a continuous evaluation of treatment plant performance.

Manufacture and trade effluent

Peak Associates regularly work with clients in various sectors, from food production to the chemical sector in matters relating to their trade effluent consents.

Our clients usually require help with negotiations regarding their existing consents or revision of their consents to match their current production discharges. This usually requires a flows and loads survey to establish the nature of the discharge, liaison with the appropriate regulator, and where necessary expert witness support.

Food Manufacturer, Berkshire

Peak Associates provided expert witness assistance to a food manufacture in Thatchem, Berkshire to help with an alleged pollution incident. Work included a factual review of the sites drainage layout to assess the claims made by the regulator that discharges from the site had “knocked out” Thames Water’s sewage works.

An expert witness report, guidance and joint expert’s meetings services were also provided in relation to allegations made by the regulator. Peak’s work proved crucial in identifying the real source of the discharges and the regulators case being withdrawn just before the case was due before the court.

Environmental Audit for Animal Feed Producer in the Midlands

This audit was carried out in response to a commitment made by the company in its Pollution Prevention and Control (PPC) permit application, which stated that it was committed to installing and operating an environmental management system (EMS) at the site.

The primary aims of this audit were to identify the main issues or aspects at the site which may impact upon the environment; to prioritise these aspects according to those which may cause a breach of environmental regulations or present the highest risk to the environment; to make recommendations for areas where improvements can be made in order to minimise these risks; to assess existing documentation procedures and whether these are appropriate for incorporation into the site EMS; to review the site's draft Environmental Policy and provide recommendations for adaptation for Company Use.

The company is currently receiving assistance in implementing an EMS to ISO14001 certification standard.

Residential development, Stockport

A FRA was requested by the LPA for a site that whilst situated in Flood Zone 1, and therefore at the lowest risk of flooding. The assessment was triggered as the site had a brook running through it. The FRA focused on the risk posed to the proposed development from flooding from the brook including run off scenarios for the brook upstream of the site and the culvert blockage on site. The report included recommendations such as finished floor levels, work required on a small culverted section of the brook which would be a throttle point in the event of heavy rainfall, and the need for a Sustainable Drainage Scheme (SuDS) to be incorporated into the design to reduce the impact of the development on flooding to the local area downstream.

Fish Farm, Cheshire

A Flood Risk Assessment (FRA) was completed for a site situated next to the River Dee in Cheshire. A commercial fish farm, which due to its nature was next to the River, required an additional agricultural building and a FRA was completed for the site as it was located within Flood Zone 3 and therefore had the greatest risk of flooding.

Work undertaken has included determining the route and connections of surface water and foul drainage to surrounding properties, and designing appropriate modifications and alterations for these connections. ecommendations for differing modes of discharge, such as outfall structures to meet Environment Agency regulations and soakaway schemes with initial percolation tests to check suitability, have also been addressed. The work includes supervising of contractors to carry out installations as per written instructions with new appropriately sized plants.

The FRA summarised the risks posed to the development and included numerous recommendations on safety features to be included within the design in order to ensure that the proposed development would be safe including a recommended finished floor level, refuge area with 24 hours of provisions, flood resilient building materials and a warning system to allow safe egress to dry land should they ever get cut off in the flood.

Legal Defence during Prosecution of Chemical Company by Yorkshire Water

The case was heard at Leeds Crown Court and involved the alleged loss of nitrotoluenes to sewer.

Yorkshire Water's case was that the works were forced out of consent for two weeks and that, as a result of this impact, a major tankering of sludge from the works was required. Waste sludges from the works was tankered by a subsidiary of Yorkshire Water Plc to a disposal facility owned by Yorkshire Water Ltd.

Our evidence showed that the breach of consent was more limited than claimed and that the levels of nitrotoluenes in effluent discharged to river was below the toxic threshold to coarse trout and other coarse fish. During the case, two of the charges were dropped by the prosecution.

Housing development, Derbyshire

Peak Associates have provided a number of services for the development of a former farm in Stretton, Derbyshire, the most recent being a feasibility report to assess the most suitable means of discharging the foul and surface water that will be generated by the site.

The work involved percolation tests at the site and conceptual designs for the location of a treatment plant and soakaway for the foul discharge. Peak also completed the Environmental Permit for the site and will liaise with the Environment Agency throughout the process to ensure this runs smoothly for our client. The conceptual SuDS design involves the use of soakaways in the residential gardens and a larger soakaway and wetland to ensure that the design will provide storage for high intensity rainfall events.

Country Estate, Stockport

Peak Associates have worked with one of the UK’s leading heritage organisations at a number of their “mansion” properties throughout England and Wales for many years. Our most recent project was at Lyme Park in Disley, Stockport. A drainage investigation was undertaken to assess the state of the existing foul and surface water drainage on the estate. A review of a wealth of historic plans was also undertaken to help find old and often buried drainage features on the estate.

Additional investigations will now be targeted to ensure that the site will finally have a full and detailed drainage plan of the whole estate which will help with the planning of future developments.

Peak Associates also assisted with a monitoring survey of the estates effluent discharge over a 12 month period. The study has provided information which has helped the estate with future developments, and helped to assess the efficiency of the Victorian sewage treatment works. With some maintenance work by National Trust staff the works are operating well.

Commercial development, Yorkshire

A joint FRA and Conceptual SuDS report was produced by Peak Associates for a former industrial site in Dewsbury, Yorkshire. The site is located near a flood relief channel and the detailed FRA included recommendations for safe egress in the event of a flood as well as the installation of an early warning system. The SuDS design included a pond to act as attenuation storage and to provide some amenity use.

As with all Peak Associates SuDS designs care was taken at design stage to ensure that a fail safe route for high intensity rain fall was included into the design. Peak Associates hopes to provide a detailed SuDS design for this site once the contaminated land issues have been resolved.

Residential development, Warrington

Peak Associates have produced a detailed SuDS design for a site in Warrington. The site had a number of technical issues that had to be overcome including an existing surface water drainage route and spring system. A SuDS design was provided to also provide some mitigation for the loss of trees removed from the site. The design included a use of a failsafe system to an existing surface water system to ensure that the site won’t flood.

The recovery, reuse and sustainable treatment of surface water run-off contaminated with de-icing fluids.

On Monday 4th of March 2013 Peak Associates attended the Bridgewater hotel in Manchester joined by 49 other businesses, graduate researchers and academic experts from Lancaster and Liverpool Universities to take part in the official launch of the Centre for Global Eco-Innovation (CGE). The CGE has been part finance by the European Regional Development Fund (ERDF) with 50 collaborations between North West businesses and Universities aimed at driving and developing new environmental green technologies and services for export into International markets.

After viewing the eco-innovation video entrepreneur and former Science Minister Lord Drayson of Kensington unveiled the 9.8 million ERDF centre, as officially open. His speech highlighted some of the key challenges technological and environmental challenges that we all face in the 21st century and how important the eco-innovation centre is in regards to addressing these challenges.

Peak Associates Environmental Consultants Ltd had an exhibition stand at the event with Managing Director Mike Matthews and research student Andrew Freeman on hand to discuss the recovery, reuse and sustainable treatment of surface water run-off contaminated with de-icing fluids. The 3 year research program aims to address environmental impacts in relation to water quality which is unavoidably contaminated during the winter de-icing season. The research will specifically focus on the design of a state of the art low cost, highly efficient treatment system, with the overriding aim of developing a product that is ready for or close to market by the end of the project.

Manchester Airport have collaborated with Peak Associates Environmental Consultants Ltd and Lancaster University to host the research project and to be at the forefront of research and development in addressing one of the key challenges which face all airports in temporal parts of the world. The results from a run-off monitoring program complete during the 2012/13 winter de-icing season at Manchester Airport are to be used to design a pilot scale treatability experiment, with research into the treatability of de-icer contaminated run-off proposed for the 2013/14 de-icing season.

The recovery, re-use and sustainable treatment of glycol pollutants at Manchester Airport

Peak Associates delivered a PhD project with Andrew Freeman through Lancaster University’s Centre for Global Eco-Innovation to deliver a system of control for surface water contamination with de-icing chemicals at Manchester Airport.

Alternative sustainable and economic solutions were investigated by Andrew. This included large-scale filtration treatment of contaminated surface water from the airfield. The results show how biochemical oxygen demand can be reduced in the effluent, reducing the impact on the local sewer system from the airport. The research, in close collaboration with Manchester Airport Group, also provided a reliable means of monitoring surface water contamination to ensure the airport remained compliant with environmental regulations.

End of Waste Criteria for trommel fines - manufactured topsoil (From small seeds great projects grow)

Peak Associates has been engaged in researching End of Waste Criteria for trommel fines which we regard as a valuable ingredient for manufactured soil. Growth trials at Lancaster University’s advanced plant science laboratories have shown soil manufactured with trommel fines to not only support grasses and wildflowers, but performing better then commercial topsoil. The sulphur content of the trommel fines is a nutrient which grasses thrive on and which a lot of grassland in the UK is deprived of.

We trialed trommel fines from waste transfer sites in Lancashire, Cumbria, and Greater Manchester. Each set of fines had different characteristics, but each proved to have acceptable levels of metals, organic and in-organic elements for soil. This work was funded through Innovate UK’s Innovation Voucher scheme.

The next phase is for outdoor trials to submit the soils for End of Waste Criteria assessment through the Environment Agency. This will be a major investment for Peak Associates and the waste companies we are in partnership with.
