Our projects

In the links below we have created a summary of the range of projects we undertake from catchment, river, lake and wetland hydrology. The news section will be updated, when clients allow the information to be released.


Longleat Estate: Lake refurbishment 2017-2018


Scampston Estate: Palladian Lakes Regeneration


Cheddar Gorge: Flood Management Project


Royal Tunbridge Wells, Grosvenor & Hilbert Park : In  2012, we worked Allen Scott Landscape Architecture to develop a pond restoration plan for the Park. The water features consisted of a cascade of small ponds flowing down a central valley within the Parkland.  he groundwater hydrology of the ponds has been massively disrupted by the urbanisation of the catchment, so additional water sources were planned into the scheme. The implementation of the work started in 2016 and is to be completed by the end of the Year.

Castle Howard, Obelisk Ponds: We are delighted, and honored, to have been appointed by Castle Howard Estate and Natural England to develop the restoration plans for the Obelisk Ponds at the Estate. These ponds were some of the earliest water features on the Estate dating from the period 1710-1730.  Over the coming year we aim to develop a detailed restoration plan for the fabric of the pond as well as enhance the overall water supply of the feature.

Lytham St Annes, Fairhaven Lake: The company was appointed by the local authority in 2016 to undertake a hydrological review of this exceptional marine lake. Working with Ryder Landscape Consulting and Jane Alexander, we will be developing restoration proposals for the lake which aim to enhance its hydrology and ecology plus sustain this regionally unique water feature.

RSPB Minnis Farm: Congratulations to RSPB for securing planning permission to develop Minnis Farm and Willow Farm, near Sandwich (Kent), into their newest wetland reserves. We have been working with the RSPB for some 4 years to secure the project and have undertaken flood risk assessments for the reserves as well as laying out the water requirements for the wetlands. This has involved the application of 1D and 2D flood models (LisFlood_MPI plus HEC-RAS).

Blenheim Palace, Queen's Pond: In 2015 the company started its initial work on proposals to restore Queen's Pond, the Brownian centre-piece lake at Blenheim Palace. Over the coming months we hope to be developing a comprehensive plan for the lakes restoration with the Estate, regulators and other specialist consultants.

Flint House, RIBA 2015 : In November 2015, Skene Catling de la Peña were awarded both an RIBA South Award, 2015, and the RIBA South Building of the Year Award, 2015 for the Flint House. The Flint House has also been short listed for the national RIBA award, as hosted by Grand Designs. Haycock worked with the architects and engineers to design the water feature through the house, its grotto and the garden channel plus ponds. The management of the quality of the water was a key consideration and measures to regulate the nutrient and thermal dynamics of the water were central to the design. For more information see Skene Catling de la Peña

Heritage Lottery Fund: In October 2015, we worked with HLF head office to review lake restoration projects and exchange experiences for the past 20 years. HLF are a key funder for public park's wishing to restore water features and their natural environments. Over the coming years it is hoped that HLF will continue to lead this work and encourage organisations to tackle, what can be intimindating, lake restoration project.

Celebrating "Lancelot Brown": In May 2016, English Heritage will be hosting a major conference on the achievements of Lancelot Brown, to celebrate 300 years since his birth. Dr Haycock was delighted to accept an invitation to speak on the "Brown, the Hydrologist" at this conference. The meeting will be at Wrest Park, Bedfordshire.

Fonthill Lake:  Over 2015 we have been supporting Fonthill Estate with the planning and execution of a large scale dredging project. The project is part of a long term plan to restore the Park and buildings within the Estate. This work has involved the removal of 300 years of accumulated material in the lake. In 2015 we planned and managed the removal of 45 000 m-cu of silt and a further 45 000 m-cu is planned for 2016.  The scheme has involved the management and protection of SSSI's, designated species and Schedule Ancient Monuments within a Grade 2 ParkLand.

Spetchley Garden: The Lake Revival:  From July 2015 we have been working on the restoration of Garden Pond. This work is nearing completion. A new clay liner has been installed into the Lake as well as changes to the runoff regime of the Garden and House to ensure a more sustainable water supply. The long term ecological health of the lake is also being addressed with aeration systems being installed and the fish ecology adjusted with the assistance of the Environment Agency. For more information, see Spetchley Garden's website. We have been involved with this project from the outset and the continued support of the HLF has been wonderful. If you are interested in developing a HLF application for the restoration of parkland and their water features, we would be delighted to discuss your project from the outset, and bring our team of associates on board to help guide you or your Estate through this often rewarding process. Our team completed its first HLF project in 2001, so we have considerable experience.

Lake Como, Italy:  Working with Italian and USA engineers, we have started work on the long term hydrology and sediment management of Lake Como. This work, over the next 2 years, will involve water quality and flood modelling work on the lake and downstream environments.

Silverlake, Dorset: In 2015, the development was granted planning permission for the restoration of 600 hectares of former quarry land and the creation of heathland and 50 hecatres of water. We have remained deeply involved in the delivery of the scheme in 2015, especially the creation and protection of the water features plus the overall management and treatment of water in order to protect downstream SSSI's and SAC's.  

National Trust, Kedleston Hall: In 2015, we were appointed to review the hydrology of Kedleston Estate and the operation of key water features within the Park. This continues a long association of the company with the National Trust, who we have supported since 1994, and completed some 62 project with their staff all over the UK.

Hampstead and Highgate Dams - Judical Review:  From 2006 to 2012 we have worked with the City of London to develop a plan to restore the hydrology and water quality of the ponds on Hampstead Heath. Since 2002 the City of London has been advised that the engineering of the dams would not able to cope with an extreme flood event and that should that flood event occur, the dams were likely to fail. In 2012, Hampstead Heath Society sought a Judical Review on the City of London's interpretation of the 1975 Reservoir Act and the level of safety required in the engineering of dams. The Judical Review rules in favour of the City of London and its engineers on the 28th November 2014. A copy of the ruling is attached for those that maybe interested. The ruling explore the history of reservoir safety in the UK and the intensions of the Government in setting up the 1975 Reservoir Act. THE HONOURABLE MRS JUSTICE LANG noted that the Government's "... main intentions are to ensure that, where a community could be endangered by the breach of a dam, the risk of any breach caused by a flood is virtually eliminated".  The role of the Reservoir All Panel Engineer is to ensure that the engineering of a dam "virtually eliminates" the risk to communities and the proposed works to the Hampstead and Highgate dams were deemed to meet this requirement by the THE HONOURABLE MRS JUSTICE LANG. Groups opposed to the works on the Dams have opposed the planning application for the scheme, which will be heard in early 2015.

Nigel Holmes: My dear friend and mentor sadly died in October 2014. Nigel was the founding member of the UK River Restoration Centre and was a champion for rivers and their ecology. From 1995 onwards the Centre has lead and tutored engineers on the skills needed to successfully restore a river or its wetland habitat. Nigel was at the centre of this effort, leading it academically and professionally, often with spade in hand. He will be sadly missed. For more information, see the Orbituary in The Independent.

Belvoir and Croxton Park: Through 2014 we have been working with Debois and NAA on the development of these wonderful parks and developing the conservation strategy for the parkland landscapes. 2015 will be an exciting year for the Parks as the planning reaches fruition. Croxton Park represents an ancient landscape, unlike anything we have worked on before.

RSPB Minnis Farm: Congratulations to RSPB for securing permission to develop Minnis Farm and Willow Farm near Sandwich (Kent) into their newest wetland reserves. We have been working with the RSPB for some 3 years to secure the permissions and have undertaken flood risk assessments for the reserves as well as laying out the water requirements for the wetlands.

RSPB Ouse Fen: Dr Haycock has worked with the RSPB since 1997 on the development of 500 hecatres of wetlands, just south of the Ouse Wash. This extensive wetland presents numberous hydrological and hydro-chemical challenges. We have developed novel hydro-chemical models that has resulted in the design of new syphon irrigation systems to sustain and hydrate this nature reserve and protect the quality of the habitats. In 2014 detailed designs for the next phase of this wetland project are being completed.

Silverlake, Dorset: In 2012 we started working with Habitat First Group to design a large holiday chalets community and landscape into an extensive quarry. The landscape will include 45 hectares of open water and associated wetlands. Designing and monitoring the water quantity and quality of this new landscape has resulted approval for the development in January 2014. The development is the first major project to be compliant with the protection of Poole Harbour SAC. Novel waste water treatment systems, including tertiary wetlands designed using the PkC* method were modelled by Haycock to meet regulators standards. For more information on the development see Habitat First Group.

Domestic Basement Development: In early 2014, we supported a prominant client in opposing the creation of a large basement development in North London.  The development was successfully defeated at a Planning Inquiry and the application rejected because of the damaged that would have resulted to adjoining properites and key trees with conservation status. Basements can have a profound impact on the movement of groundwater and correct investigations are required.  Basement Impact Assessment is now routinely required, but the quality of the information and its interpretation is central to a complete assessment of the risks involved.
