4 ACO MultiDrain PPD Introduction to ACO MultiDrain PPD The new ACO MultiDrain PPD channel and grating system provides versatile and efficient linear drainage for infrastructure and hard landscaping projects. What is ACO MultiDrain PPD? ACO MultiDrain PPD m constant depth channel elements are available in 3 widths: mm, 50mm and 200mm. This gives the designer the means to select the optimum channel size and hydraulic performance required, minimising the number of outlets and keeping installation costs as low as possible. An extensive choice of grating styles, materials and load classes is available fitted with the ACO Drainlock fastening system, which provides simple and quick installation yet prevents traffic displacing the gratings. If there is a risk of unwanted grating removal or theft then security locking systems are available. Where slot drainage is preferred ACO Brickslot tops are available for the mm and 50mm wide channels, providing discreet slot drainage in either block paving or natural stone surfaces. The offset drainage slot also enables ACO Brickslot to be used right up to building façades or for threshold drainage. 4 Why choose the ACO MultiDrain PPD system? The system meets the highest standards for performance and quality, being fully compliant with and independently certified to BS EN 433:2002 for applications ranging from A 5 up to and including D 400*, ideal for pedestrians, cars, service vehicles or HGV traffic. The constant depth m recycled polypropylene channels with protective galvanised steel edge rails are extremely robust and durable yet all weigh under 5kg thanks to ACO s unique HexTechnology channel structure. ACO MultiDrain PPD has the performance to withstand the rigours of installation and provide long service life. Installation and maintenance costs are kept to a minimum with each channel packed with labour saving features, such as clip together end details for rapid channel connection and alignment, knockout panels for outlet pipe work, and the V shaped channel bore that promotes self cleansing. Guidance on preparation, installation and maintenance of this system is given in the ACO MultiDrain PPD installation manual or visit

5 Typical applications The ACO MultiDrain PPD system can provide a channel drainage solution for many applications by selecting the appropriate channel width, depth and grating type.

16 ACO MultiDrain PPD ACO MultiDrain MPPD hydraulic performance tables 6 Hydraulic capacities The table opposite shows the maximum capacity of the channel, assuming uniform lateral inflow to the channel. The capacity will depend on the length of channel to the outlet and on any slope along the channel. Q (l/s) is the maximum total flow that the channel can carry. q (l/s/m) is the maximum possible lateral inflow. A (m 2 ) is the maximum area that can be drained and will depend on the design rainfall intensity chosen. The tabulated areas are for a rainfall intensity of 50 mm/h (0.04 l/s/m 2 ). At other rainfall intensities, the area can be determined by proportion, e.g. at 75mm/h, the maximum area drained will be the tabulated area x 50/75.

29 Designing a drainage system The hydraulic capacity of channels accepting lateral inflow all along their length can be calculated by the analysis of the differential equations for spatially varied flow, a procedure that requires a computer program such as the proprietary ACO Hydro software. For detailed designs using Hydro, please contact the ACO Water Management Design Services Team. The team should also be consulted for advice where the inflow is not uniformly distributed along the channel. The hydraulic performance tables within the relevant sections have been produced from the ACO Hydro software to facilitate a quick manual design method for the determination of the drainage requirements. The columns of drainage catchment area (A m 2 ) are based on a rainfall intensity of 50mm/h, but can be adapted for use at any rainfall intensity. The columns of maximum flow rate (Q l/s) and maximum lateral inflow (q l/s/m) can be used at any rainfall intensity. DESIGN EXAMPLE i = 50mm/h D = 5m L =40m For a design of ACO MultiDrain MPPD, assume the following figures: D = 5m (depth of catchment area) L = 40m (length of channel run = length of catchment) i = 50mm/h (design rainfall intensity) Ground slope = 0% Note that any other rainfall intensity may be used. Typical intensities (from BS EN 752) are 50mm/h for areas where some ponding could be tolerated for a few minutes after heavy rainfall, or 75mm/h where ponding cannot normally be tolerated. 29. Determine the area Area = L x D = 40 x 5 = 600m 2 For a quick analysis, see the tables and the columns for area on page m 2 is too large for one 40m run of ACO MultiDrain MPPD. However a 20m run can drain 302m 2, so one central outlet will work, with 20m of channel each side, each draining 300m 2. Or for a more detailed analysis, determine the total flow rate, as follows: 2. Determine total flow (Q) Q = (area x i) / 3600 = (600 x 50) / 3600 = 8.33 l/s 3. Determine lateral inflow (q) q = Q / L = 8.33 / 40 = l/s/m 4. Determine suitable channel sizes and lengths For ACO MultiDrain MPPD interpolation between the value at 20m and 30m, a maximum length of 2m could carry l/s/m. Alternatively use ACO MultiDrain M50PPD to an end outlet, where the tables show that 40m can carry 9.8 l/s and drain 704m². 5. Check Outlet capacity Ensure that the proposed outlet has sufficient hydraulic capacity by reference to the product technical pages.

33 Chemical resistance chart ACO polypropylene has a high resistance to dilute acids and alkalis, and is unaffected by road salt, fuel and oil, and other commonly encountered chemicals. Further details of the chemical resistance can be obtained from the ACO Water Management Design Services Team or for particular chemicals, samples of the polypropylene channels can be supplied to customers for their own testing. The chemical resistance will also depend on the temperature of the effluent. The resistance of the gratings and edge rails should also be considered. This chemical resistance chart refers to chemical at ambient temperatures (20 C) and the results are for general guidance only. Important considerations for chemical environments When reviewing potential applications for ACO MultiDrain PPD in chemical environments, the following issues should be considered; Type(s) & mixture of chemical(s). Concentration percentages. Contact time with drainage system. Temperatures of chemicals flowing into the drainage system (82 C max). Flushing system employed to clear chemicals from the drainage system. Cleaning agents should be checked for compatibility with channel materials. ACO samples can be used for final determination of chemical resistance. Grating, locking mechanism, edge rail, outlet and sump unit materials should be checked for chemical resistance. Check sealant for compatibility.

34 ACO MultiDrain PPD Frequently Asked Questions 34 Q WHAT LOAD CLASS DO I REQUIRE? Answer: The answer to this question is dependent on where the drainage system will be used. There are six load classes recognised in BS EN 433:2002. For further information on load classes and applications relevant to this system, please refer to page 7. Please note that all channels within the ACO MultiDrain PPD system are certified to BS EN 433: 2002 Load Class D 400*. The system has a wide range of gratings with varying load classes which, once installed with the channel, determines the system s load class. Careful consideration should be given to the application requirement when selecting a grating. * Not suitable for carriageways of public roads or motorways Q2 DO I NEED A SUMP UNIT/UNIVERSAL GULLY? Answer: This is dependent on the requirements for sediment collection or a foul air trap. If either of these are required then a sump or gully is necessary. If not you can use any of the other outlet options available. The ACO Universal Gully (3360) has a roddable foul air trap built into the side of the unit. Note that the hydraulic capacity of end outlets and bottom outlets will be much less than the capacity of a sump or gully. Q3 ARE ACO CHANNELS SUITABLE FOR USE WITH CHEMICALS? Answer: This is entirely dependent on the chemicals being used along with their temperature and concentration. For more information, please refer to the ACO MultiDrain PPD chemical resistance chart provided on page 33. Q4 WHICH PRODUCTS ARE SUITABLE FOR USE WITH LEVEL ACCESS THRESHOLDS? Answer: Most ACO channels are suitable for level thresholds and are Part M compliant. ACO recommend systems such as ACO MultiDrain PPD, ACO MultiDrain MD or ACO ParkDrain are used for public thresholds where security of the gratings needs to be taken into account. These systems are all available with Heelguard gratings which limit the possibility of stiletto heels being caught. Q5 IS THERE A REGULATION REGARDING HEELGUARD? Answer: No. Heelguard is name created by ACO for gratings where the slot width is around 8mm. ACO MultiDrain PPD has a choice of Heelguard gratings and also a selection of wider mm slot gratings. The standard for surface water drainage BS EN 433:2002, states that the maximum slot width in most pedestrian situations is 8mm. Q6 HOW MANY OUTLETS ARE REQUIRED IN A RUN? Answer: This depends entirely on the length of channel and the catchment area expected. A design example is provided in the hydraulics guide on page 29. If a specific hydraulic calculation is required, please contact the ACO Water Management Design Services Team on Q7 DO YOU MANUFACTURE PRECURVED CHANNELS? Answer: No. ACO do not provide precurved units. However our sister division, ACO Building Drainage manufacture a stainless steel precurved product called ACO Radius channel and the ACO Sport product range includes channels to the 36.5m radius of an athletics track. For information on these products please call or refer to Q8 ARE ACO CHANNELS SELF CLEANSING? Answer: Not entirely, but the V shaped channel bore improves speed of water flow and promotes a degree of self cleansing. If there is a significant ground slope, for instance in excess of 2%, self cleansing could be achieved. We recommend any channel system is cleaned at least once a year to ensure optimum performance. Q9 ARE PRE SLOPED CHANNELS AVAILABLE WITHIN THE ACO MULTIDRAIN PPD RANGE? Answer: No, but pre sloped channels are available within the ACO MultiDrain MD range. Q HOW DO I MAKE THE ACO MULTIDRAIN PPD SYSTEM WATER TIGHT? Answer: Instructions are provide in the ACO MultiDrain PPD Installation manual. This brochure is available to download from or contact marketing@aco.co.uk to request your copy. Q ARE RECYCLED MATERIALS USED IN THE PRODUCTION OF ACO MULTIDRAIN PPD? Answer:, ACO MultiDrain PPD channels are manufactured using recycled polypropylene. All other components within the range also contain recycled materials. For more information on the recycled content, see opposite.

Assistance in completing this clause can be found in the ACO Drain entry in NBS Plus, or please contact the ACO Water Management Design Services Team. Note: A specification in NBS format is available to download from or Recycled content ACO Technologies aims to incorporate as much recycled material or waste material as is practicable in its manufactured products. Typically, cast iron materials contain 40% to 90% recycled iron, and steel products contain 25% to 33% recycled steel. The total recycled content of the ACO MultiDrain PPD system will vary as the proportion of different materials (in the channel, edge rails, gratings etc) varies. As an example the ACO MultiDrain PPD channel with Heelguard ductile iron gratings will contain at minimum approximately 35% by weight recycled material. The ACO MultiDrain PPD products are themselves intended for a long life with low maintenance, to reduce the need to recycle, but when eventually they are no longer needed, much of their content can be readily recycled with a very low risk of pollution to the environment. 35 Conformity The ACO MultiDrain PPD system is CE marked and fully certified to BS EN 433:2002.
