Winter Colour

This picture of the Severn Acre lake at the Royal Horticultural Society Garden Wisley shows what can be achieved when skilled and knowledgeable gardeners decide to create some winter colour next to a lake.

We first worked on the Seven Acre lake nearly twenty years ago, we cleaned it out, installed some revetment and put in a bentonite cut off trench to help maintain summer water levels. We also built a cascade and pump system all in the wettest autumn for years.

Last year we were asked to build a retaining wall around part of the lake to support the bank, and then the RHS staff took over with the planting, with the spectacular results in the photograph.

Looking in the Archives – A lake for Super Tankers!

About five years ago we were asked to carry out all of the modifications required to an existing fishing lake and a series of stew ponds at Timsbury near Southampton to form the Manned Model Training Facility for Southampton University.

This new development was to provide a safe environment for training senior deck officers and pilots, to give them experience of close quarter manoeuvring and berthing large oil tankers, ferries and similar ships

The training programme uses scale model ships of 9m or 10m long operating on an inland lake to simulate the behaviour of real, 350m long, 300,000 tonne  vessels. This is a unique facility in the UK and we were delighted to be asked to help with its construction.

Morgan Sindall were the main contractors and after a lot of discussion and design meetings our work started with widening the footpath through the undergrowth to create a vehicle access to the lake. We then launched pontoons and floating plant to open up a passage between the various separate water bodies, we desilted deep water channels and dug a narrow canal around the top of the lake.

Concrete and steel retaining walls were designed and installed, bio engineering was completed, and different types of jetties and docks were manufactured, some were pontoons moored on tubular piles, others had either solid or pierced underwater profiles to simulate the different types of harbour wall construction that the mariners would encounter.

While we did the lake works, the main contractor built the training facilities, workshops and classrooms.

It was an interesting and successful scheme that tested our ingenuity and because of the poor access and soft ground, it needed innovative approaches to overcome problems of construction.

Below is a link to the training facility website and a youtube video of the lake and its operation, hope you enjoy watching.

As Good As New!

Kingcombe have been busy over the past 6 months de-silting in various locations over the South West including a project near Dorchester.

Working with the Environment Agency, we carefully reinstated a section of River back to its original condition.

Before the works started, an ecologist surveyed the area which determined when the work could take place and agreed the working methods.

A pre-start meeting took place to agree access, parking and emergency procedures.

Prior to starting, a detailed site specific inspection, environmental and site risk assessment and methodology were completed.

Using a hydraulic excavator and a dumper, the silt and vegetation was removed from the river to a stockpile for later disposal.

And it doesn’t stop there for 2016! This month, one of our site teams will be busy right up to Christmas de-silting a private lake near Warminster.

De-silting has been one of Kingcombe’s core activates for nearly 30 years and it gives us great pleasure to return a lake/pond/river or reservoir back to its original beauty.

Please contact us if you require further information on de-silting.

Three Ponds Desilted

image-1Over the years desilting has been a core activity for Kingcombe Aquacare. Whether it is large lakes and reservoirs or small ponds, we have cleared them of silt to give them a new lease of life.

Our latest desilting project was to clean out three pools in the beautiful gardens of a house in Somerset for a Private Client. We have previously cleaned the ponds out around 12 years ago. The smallest was about 300m2 in surface area and the largest pool  around 1400m2 with up to 1m depth of silt.

The water was drained out and then the silt loaded into a pumping system to move the waste around 1km to farmland.

We applied on behalf of the Client for an exemption to the waste regulations to allow the legal disposal of the silt to land.

The work took a couple of weeks to complete before we allowed the three ponds to refill.
