RAINWATERSOLUTIONSNEW SOUTH WALES
RAINWATER SOLUTIONSWater overflow in domestic rainwater systemsUnder the Environmental Planning and Assessment Act 1979 and its Regulations, all building work must becarried out in accordance with the ABCB National Construction Code 2016 (NCC). In addition to referringto Australian Standards AS/NZS 3500.3:2015 Plumbing and Drainage – Stormwater Drainage, the NCC alsocontains requirements for the disposal of surface water in Volume One, in Performance Requirements FP1.2and FP1.3, and in Volume Two, in Part 3.5.2, namely, Performance Requirements P2.2.1 and Clauses 3.5.2.1and 3.5.2.4.The most common means to satisfy these requirements for roofdrainage (i.e. guttering) installations is via compliance with theAS/NZS 3500.3.B) Methods related to alternative building designs methods:Furthermore, in each state and territory it is necessary to satisfythe relevant regulation. For example, the NSW Code of Practicefor Plumbing and Drainage (2006) adopts AS/NZS 3500.3 andassociated amendments. G utter installed such that the gutter front is fully and sufficientlybelow the top of the fascia (freeboarding).In the design and detailing of a roof drainage system considerationmust be given to a range of the factors such as rainfall intensity,roof catchment area, gutter size/capacity, gutter fall, gutteroutlets (sumps, rainheads, nozzles), downpipe size, quantity andplacement, overflow consideration, material selection, jointing, etc.It is the responsibility of designers and installers of roof drainagesystems to ensure compliance with these requirements.IMPORTANT INFORMATION ON OVERFLOW MEASURESFor residential roof drainage systems, high fronted gutters are apopular aesthetic choice to hide the lower edge of tiles or roofcladding. Where high-fronted gutters are installed, the NCC (andAS/NZS 3500.3) requires that provision must be made to avoidany overflow back into the roof or building structure.Some simple overflow control methods that can be employed onhigh fronted gutters are listed below. It is important to note thatit may be necessary to use more than one of these measures toachieve the necessary result: U nlined eaves – eliminates the issue where the house designsuits. D esign for a higher rainfall intensity, as used for internal boxgutters. B ack flashing – where gutter support brackets allow backflashing installation (e.g. external brackets).The following illustrations show some typical continuous and noncontinuous overflow measures that may be used in combinationwith each other or with other overflow measures to meet thenecessary requirements.Please note that non-continuous measures may become blockedanywhere along their length, so non-continuous overflow measuresmay not be sufficient to prevent water from flowing back into abuilding.Slotted gutters may also provide an overflow measure, howeverslots must be of sufficient size. For this reason, slots alone maynot be a sufficient overflow measure in all circumstances. Whendesigning a roof drainage system with slotted gutter, considerationshould be given to additional overflow measures.A) Methods related to the design and installation of roof drainagesystems: S lotted front of gutter – simple and popular choice which allowsfor water overflow through the slots visible on the front face ofthe gutter; Specifically located non-continuous overflows as permitted inthe NCC i.e.:-- I nverted downpipe drop/pop at high points in the gutter butset at a level below the fascia top,-- Stop ends cut down to a lower level to act as a weir (stopend weirs could be hidden at the high point of the gutter anddesigned as part of an expansion joint),-- Rainheads with overflow weir,RAINWATER SOLUTIONS-- Holes, slot, or weir at downpipes; Gap between the fascia and the gutter back – a packer isinserted between the gutter back and the fascia; or Any of a number of other proprietary systems and tradesolutions.Typical overflow from slotted gutter.(Gutter shown is not available in all areas).2
DESIGN AND INSTALLATION OF DOMESTIC ROOFDRAINAGE SYSTEMSContinuous (full length) overflow measuresThe detailing and sizing of the selected overflow method/sis normally completed by the designer/installer, but must beadequate for the situation and must meet the relevant performancerequirements of the NCC and Australian Standards, including therequirements noted above.While there may be some variations from state to state, contractorswho install guttering systems are generally required to hold anappropriate licence. In NSW, for example, a licence in the categoryof Builder, Plumber or Roof Plumber issued by the Office of FairTrading is required and it is an offence to undertake this workwithout an appropriate licence. The work is required to complywith the appropriate codes and standards.GutterFront of gutter below top of fasciaFasciaStatutory warranties normally apply and consumers have a rightto lodge a complaint and have it dealt with by the appropriateauthority. In NSW, for example, the statutory warranty is up to6 years under the Home Building Act.GutterGap between gutter and fasciaIn the installation of the roof drainage system, particular focusshould be given to the following; Attention to the use of compatible materials for drainagesystem components, leaf-guard type system componentsand compatible fasteners/sealants to connect and seal thecomponents.Non-continuous (specifically located) overflow measures The position of the gutter in relation to the fascia (particularly,whether there is a gap between the fascia and the gutter backand whether the gutter front is below the top of the fascia).Downpipe nozzle I nstallation of the specified gutter and downpipes, ensuring thatdownpipes are installed in the correct locations and numbers.Gutter Gutter fall, ensuring sufficient fall and that it is in the direction ofthe downpipes. O verflow has been considered and specific details are installedwhere required as described above (such as when the gutterfront is higher than the top of the fascia).During the installation all debris and loose waste materials (swarf,fasteners, etc.) must be cleaned off at the end of each day andat the completion of the installation to prevent blockages of thedrainage system or deterioration of the individual components. Anyprotective films should also be removed as part of the installationprocess.MAINTENANCE OF DOMESTIC ROOF DRAINAGESYSTEMSInverted nozzle at high ends of gutterfinished below back of gutterFasciaGutterStop ends finished below the top of thefascia and rear of the gutter to form a weir3To ensure the long life of the roof drainage system, themaintenance requirements of the roof drainage system should beforwarded to the occupier/owner of the building and should befulfilled. Adequate maintenance is a requirement of rainwater goodswarranties.RAINWATER SOLUTIONSIn the longer term, the ability of a roof drainage system to handleoverflow will also depend on the regular cleaning of the system.For example the removal of plant or animal matter (leaves, fungalgrowth, dropping, nests, etc.) and debris from gutters, leaf-guardtype systems and the gutter overflow devices to ensure freedrainage of water.
Information on designing a perimeter drainage systemfor a domestic roofRoof drainage systems can be affected by a number of variablesand must be designed and detailed by a suitably qualified trade orprofessional. The design of roof drainage aims to protect people,property and the building. The designed drainage system must beinstalled under the supervision of a qualified trade or professional.The steps of the design process are illustrated below.1. D ecide on the average recurrence interval (ARI). Wheresignificant inconvenience or injury to people, or damage toproperty (including contents of a building), is unlikely (typicalof an eaves-gutter system) a minimum ARI can be 20 years. Ifthese conditions are likely (typical of box gutters) 100 years isrecommended.1. Determine average recurrence interval (ARI).2. Determine rainfall intensity for the site from Table 1. More dataare in AS/NZS 3500.3.2. Obtain rainfall intensity of site.3. Sketch a roof plan showing dimensions in plan view, pitch ofroof, layout of ridges and valleys and large roof penetrations.3. Work out roof dimensions.4. Determined catchment area with slope.5. Determine area for proposed eaves gutter.6. Determine catchment area per downpipe.7. Determine number of downpipes required.8. Determine location of downpipes and high points.9. Check catchment area for each downpipe.10. Determine downpipe size.5. G et the effective cross-sectional area of the gutter you intend touse from Table 2.6. U sing the cross-sectional area of the gutter on the graph inFigure 1, determine the catchment area per downpipe.7. Calculate (as a first test) the minimum number of downpipesrequired for the selected gutter using the equation:11. Determine overflow measures.Table 1Design rainfall intensities adapted from NCC, Volume 2, Table3.5.2.1.ARI once in 20 yearsmm/hrARI once in 100 yearsmm/hrACTCanberra4. Calculate the catchment area of the roof from the plan. To allowfor the slope of the roof, increase the plan area. Refer toAS/NZS 3500.3 for the increased area.

Total catchment area of the roofCatchment area (determined in 6)Round the number of downpipes up to the next whole number.8. On the plan, select locations for the downpipes and the highpoints in the gutters. Where practical, the catchments for eachdownpipe should be about equal in area.When selecting the location of high points and downpipes,consideration should also be given to proximity to highconcentrations of water flow (e.g. valley gutters, diversionsaround large roof penetrations, dormers, etc.). More guidanceis given in AS/NZS 3500.3, HB114:1998 and NCC.Calculate the area of each catchment for each downpipe.9. With the area of your eaves gutter, check that the catchmentarea for each downpipe, calculated in Step 8, is equal to or lessthan the catchment area shown by the graph.If a catchment area is too big then you can:200262 Increase the number of downpipes;Avalon206278 Reposition the downpipes and/or the high points;Campbelltown167222Penrith180244 Choose a gutter with bigger effective cross-sectional area,then repeat the above from Step 6.Sydney175233Tweed HeadsWindsor252330Wollongong217308DESIGN PROCEDURERAINWATER SOLUTIONSThe steps in the design process are for a perimeter drainage systemusing the standard roll-formed rainwater products (gutters) installedat the building eaves. Drainage systems for larger roofs use boxgutters at the perimeter and internally. Box gutter systems arethoroughly treated in AS/NZS 3500.3 and HB114:1998.Diagrams, charts and data extracted from other publications (suchas NCC, AS/NZS 3500.3, etc.) are indicative only. Referenceshould be made to these other publications for the most recentinformation.4Install gutters with a suitable fall to avoid ponding and to allowwater to easily flow away. Steeper falls are preferred for prolongedlife of the gutter. Refer to the NCC and the Australian Standards forguidance. Eaves gutters must have a gradient of 1:500 or steeper.10. Decide on the downpipe size. Recommendations inAS/NZS 3500.3 on downpipe sizes. Table 2 gives the standardsize downpipes available to suit the requirements given inAS/NZS 3500.3.11. C onsider measures to counter potential overflow of gutters intothe building (see pages 2 and 3). Consideration of overflowat high concentrations of water flow may need to be given.Guidance on this matter is given in NSW Dept of Fair Tradingbulletin FTB40 (January 2009).Overflow capacity of slots in the LYSAGHT gutters are provided inTable 3.

INSTALLATION ADVICEGet it right first time with LYSAGHT productsBRACKET SPACINGADVERSE CONDITIONSWhen the gutters are attached to NOVALINE fascia, thenthe gutter bracket spacing should mirror the spacing of theNOVALINE brackets (i.e. 600mm & 1200mm), and the gutterbrackets should be adjacent to the NOVALINE brackets.If these products are to be used within 1km of marine, severeindustrial, or unusually corrosive environments, ask for advice fromour information line.However, when the gutters are fixed to other fascias then theweight of the water carried by the gutter should determine spacingrequired - however spacing should not exceed 1200mm maximum.The roof drainage system should be installed using good tradepractices and by a certified installer. FALLInstall gutters with a suitable fall to avoid ponding and to allowwater to easily flow away. Steeper falls are preferred for prolongedlife of the gutter. Refer to the NCC and the Australian Standards forguidance.METAL & TIMBER COMPATIBILITYRAINWATER SOLUTIONSLead, copper, bare steel and green or some chemically-treatedtimber are not compatible with this product; thus don’t allowany contact of the product with those materials, nor discharge ofrainwater from them onto the product. If there are doubts about thecompatibility of other products being used, ask for advice from ourinformation line.ROOF DRAINAGE SYSTEM DESIGNRoof drainage systems should be designed and detailed by asuitably qualified trade or professional in accordance with theNCC and the Australian Standards. Particular reference should bemade to the correct sizing of gutter; quantity and placement ofdownpipes; and the provision of appropriate overflow devices.(Page 2-3).INSTALLATION ADVICEFor sealed joints use screws or rivets and neutral-cure siliconesealant branded as suitable for use with galvanised orCOLORBOND /ZINCALUME steel.CLEAN UPRemove all plastic cover strips from product and dispose ofcorrectly.Sweep all metallic swarf and other debris from roof areas,gutters, downpipes, overflow devices and all other roof drainagecomponents, at the end of each day and at the completion of theinstallation.GUTTER MAINTENANCEThe roof drainage system (gutter, downpipes, overflow devices andall other components) must be cleaned out on a regular basis.10
GUTTER MAINTENANCEGetting the most from LYSAGHT products1) A typical suburban gutter clogged withleaf litter prior to cleaning.2) Wear correct protection when clearingleaves and twigs.3) When litter is removed, the layer ofhardened dirt is revealed below.4) Rinse the gutter with water to softenand break up the dirt.5) Use a soft bristle brush and sweepthe dirt out. Rinse again.6) When the gutter has been cleaned,it should look like this.CLEANING GUTTERSTwigs, dust, leaves and fungal matter (debris) should be removedregularly from gutters - as failure to do so voids your warranty. S weep debris into a pile using a stiff, soft bristled brush (shovelsor hard tools should not be used).11A well maintained gutter/downpipe will make your rainwatersystem provide years and years of trouble-free service.RAINWATER SOLUTIONS The whole roof and gutter should then be washed down witha hose, including high ends of gutters (possibly protected byoverhangs), rain heads, water spouts and overflow locations.
