OVERVIEW

Circular Economy Solutions Limited offers “hard engineered” solutions which are genuinely sustainable, offer a defined level of performance which is proven, measurable and predictable. We only offer products which can provide a level of performance which can be maintained, in fact, everything that SUDS doesn’t.

PRODUCTS AND SERVICES

 

STORMWATER AND WASTEWATER - FLOW CONTROLS

Contact us for support in identifying the optimum flow control solution for your project or development. The flow controls offered by Circular Economy Solutions Limited are :-

 

Throttle pipe

Controls flow in one of two ways, either as a physical barrier using the size of pipe to determine the flow that passes when a specific upstream head acts on it, or, the pipe is longer, and its length will have a friction loss among it which will determine the flowrate. We can provide what you need with minimal information.

 

Orifice Plate

Controls flow as a physical barrer using the size of orifice to determine the flow that passes when a specific upstream head acts on it. Our modular orifice system allows various size ranges to be fitted into a single size of chamber.

 

Vortex flow control

The same device offers two methods of controlling flows downstream. Firstly it controls flow through the physical size of the aperture. Secondly, once rotational flow is achieved within the device, an air core forms and the presence of the air core limits the flow of fluid causing a “kickback point” and the air core restricts fluid flow downstream as head continues to build upstream. This type of flow control may not be the cheapest, but is likely the best, and will save you a fortune if installed as part of an integrated stormwater management system.

 

Variable orifice flow control.

A variable orifice flow control is a device which has a variable geometry shaped opening attached to a float mounted on the downstream side and as the float rises, it closes off the opening and thus reduces the flow allowed to pass, when the level drops, so does the float and the aperture opens up, and so on…. Self acting, self regulating

 

Modulating Penstock

A modulating penstock is a type of valve which utilises a gate which travels vertically in a frame to control flow. It simply works in conjunction with a level controller which also in conjunction with a flume flow measurement device, will give a signal to the penstock actuator to open or close the penstock gate. Clearly by opening and closing the gate will vary the flow. A simple and effective device, needs power and control logic however.

Actuated Valve

An actuated valve is simply a valve with an automatic adjustment mechanism, this one has a pneumatic actuator, there are a variety of type of valve and actuator available to suit your application

 

The flow control products above are tailored to suit your application, including materials used, scale, cost and performance. Please contact us using the form or email for further support.

 

Remember the incorrect assessment of your flow control can result in significant oversizing of storage and cost you or your client thousands so don’t get it wrong, share in our expertise.

STORMWATER ATTENUATION

Stormwater Attenuation

Hard Engineering solutions for the most sustainable, lowest cost and safe systrem.

ATTENUATION

Attenuation, or “storage” can take various forms depending on the drivers in force. We do not do wet or dry Ponds, swales and the like, we only do hard engineered solutions which are :


LoRAS© ™

The LoRAS© ™ “Local Reuse and Attenuation System” is designed, developed and provided only by Circular Economy Solutions Limited. This system offers a turnkey packaged system of :-

  • A custom formed attenuation and re-use storage volume, load bearing for locating under driveways or other available footprint.

  • Unique weldless tank design reduces leak paths

  • A flow control chamber to manage flows from the site

  • An upstream debris removal system to maintain the cleanliness of the attenuation volume

  • An automatic indication of re-use volume and switchover to mains water back-up

  • A solar powered re-use pump with mains power back-up

  • A stored and pressurized volume of re-use water to support cisterns only.

  • Auto control and operation of the complete system

  • All interconnecting pipework throughout the development / unit


This is a complete and customised package for the developer to fit out using their existing trades. The benefits of a LoRAS© ™ system are simply :-

  • In relation to stormwater management, we do all of the thinking.

  • The modular system is the most efficient per cubic metre of excavated material

  • The modular system is adaptable, can be deep or shallow, wide, long, totally customised

  • The attenuation of stormwater is done at source.

  •  A genuine re-use system offers a sustainable solution to toilet flushing and hosepoints around the site. All designed, packaged and supplied as a kit with full instructions.

  • An installation service is available

  • Does not require concrete surround to offer its load bearing condition

  • The system is designed to operate off-grid providing water for re-use at zero cost and zero carbon

  • Full system backup to mains water and power providing peace of mind.

  • Lower cost and better use of land for developer output when considering stormwater management.


ReRAS© ™

 GRP Tanks

Glass reinforced plastic tanks, mostly associated with smaller attenuation volumes, cesspools/pits and biological treatment plant. Normally installed with a concrete surround and have a lower invert depth due to being circular. A modular, low cost solution for smaller attenuation volumes.



Plastic Tanks

Plastic tanks, similar to GRP, Normally installed with a concrete surround, can be circular but may be other shapes.


Modular Block Attenuation

The basis of the LoRAS© ™ and ReRAS© ™ systems but without any re-use consideration or packaged solution, A simple attenuation system prepared within a geotextile membrane to form a tank. For anyone unsure of the value of this type of storage, look at the benefits stated below :-



Benefits of modular composite attenuation systems are :-

  1. More attenuation per cubic metre of material removed as the blocks are 95% free volume

  2. The shape of tank fits an excavator bucket almost perfectly with no waste of a round tank

  3. Load bearing blocks are ideal for trafficked areas. We customise to suit so you never over-specify or over-pay.

  4. Super flexible from a developer perspective, spread your storage over the site within multiple sites, have a deep installation with small footprint or shallow installation with large footprint, what suits the site best is what we provide, its customised to suit you.

  5. Lowest cost of all attenuation systems

  6. No need for concrete surround like plastic or GRP tanks

  7. Fast and easy to install with no cranes or special handling, simply manually installed.

  8. Unlike ponds, it’s out of sight, safe and does not present a drowning risk

  9. Buried systems maximise the return from a development site, delivering more units per acre just when we need more homes built.

Stormwater Treatment

Innovative and efficient

The treatment of Stormwater is done so in order to reduce maintenance of attenuation systems. For example, “sustainable” systems which incorporate ponds are thought that on average, these will silt up in under 10 years and therefore offer no attenuation, and no treatment beyond that point. Ponds are also designed without any routine maintenance facilities and as such, will likely be damaged through any maintenance attempted, torn liners etc. These “sustainable” solutions are in fact the least sustainable of all and that’s not our view, its based on fact. 
The following are treatment options we offer which will protect attenuation systems but more importantly, are designed with routine maintenance in mind. These are in fact the genuine sustainable.


Downstream Defender©  - Hydro International product designed to have a specific performance for the removal of silts and grits with a specific gravity of 2.65 down to 200 microns. Also entrains floatable materials. No moving parts, no power, maintained through routine cleaning with a gully sucker.
 
Gully pot – simple low volume removal of silts and grits. Cheap, not efficient as tend to wash out during high storm flows. Maintained by gully sucker but many of them means this is a task which is too intensive to be routine. 

Class 1 Interceptor –  SUDS compliant hydrocarbons retention. 


Class 2 Interceptor – provides a means of solids retention as well as low level hydrocarbons capture
