In recent years the prolonged wet weather will have highlighted failures in Sports Field Drainage systems. CLS sports are experienced in all aspects of Sports Field Drainage and Construction. CLS sports are able to offer a complete professional design and build package covering all aspects of drainage, attenuation, irrigation and construction tailored to suit your sport and budget.
Primary drainage systems
Primary piped land drainage systems form the base infrastructure of any subsequent secondary systems. A primary system removes ground water through a network of pipes to an outfall or storage/attenuation tank.
CLS sports offer a full sport pitch drainage design and construction service, taking account of factors such as soil type, topography and availability of outfalls, storage and attenuation.
All drainage systems are installed using specialist trenching machinery guided by laser level controls. Two main type of trenching machinery are used:
- Continuous chain trenchers
- Rotating wheel trenchers
Each has their place in the construction of a drainage scheme, their use is dependent on the ground conditions and depth/width of the drainage trench. Each trencher has been designed with sports drainage in mind and are fitted with low ground pressure tracks or attached to tractors with low ground pressure tyres to minimise compaction on the sports ground.
Secondary drainage systems intercept and collect surface water and transfer it quickly to the lateral drains of the primary system. The installation of a secondary system rapidly speeds up the time taken to clear a sports ground of surface water. This rapid removal ensures that playing surfaces are in use again as soon as possible following heavy rainfall.
Typical secondary drainage operations can include:
- Ground decompaction
- Sand slitting
- Piped sand slitting
- Sand banding
- Sand Amelioration
CLS sports have invested heavily in specialist equipment to carry out the operations listed above, including but not limited to:
- Mastenbroeak 10/12D Sports drainage trencher
- AFT 100 Chain Trencher
- AFT Whiz Wheel 55 Trencher
- AFT Whiz Wheel 75 Trencher
- KORO Topdrain 1500
- Blec Sandmaster
- Blec Groundbreaker
- Blec AGRI-vator
- Wiedenmann Verti-Drain
Water management and attenuation
Removal of surface water in some installations is only the start of the waters journey away from the playing surface. CLS sports not only design and construct primary and secondary drainage system but water management and attenuation systems as well.
Water management can be achieved in the form of underground attenuation systems such as:
- Rotational Moulded plastic tanks
- GRP tanks
- Wrapped stone
- Plastic crate systems
The flow from all of these can be controlled with the installation of flow control valves (or Hydrobrakes) to regulate the rate of discharge into drainage outfalls and watercourses to prevent flooding in storm conditions.
Sport Pitch Irrigation
In stark contrast to the drainage systems highlighted above an irrigation system for your sports pitch is a must if you are to achieve the right quality and durability playing surface all year round.
A professionally designed and installed irrigation system for your sports pitch can make the difference during the playing season. As most well designed sand and root-zone based sports pitches incorporate extremely efficient primary and secondary drainage systems, irrigation is a necessity for promoting constant grass growth all year round. Irrigation can minimise dry hard soil conditions experienced during the short hot periods of the spring and summer.
Systems designed by CLS sports can incorporate:
- above ground rolling sprinklers
- above ground static sprinklers
- gear driven pop-up sprinklers with electric valve-in-head
- in field centre grass buckets
- impact driven full circle pop-up sprinklers
We will always endeavour to design a scheme to minimise the visual or safety aspect of pop up sprinklers on the playing surface. In addition all schemes will be designed to have the correct coverage, the right control system and water storage system to suit your individual situation.
