Water Management & Conservation Responsible water use and waste water management plays an important role in events’ sustainability agenda. For events, water is needed for:            Cleaning Catering Food stalls operations Toilets and amenities Standpipes Drinking taps Dust settling Grounds preparation Garden irrigation Vehicle or equipment wash down Inputs for event activities 4 Source: Event Sustainability Management (Jones, 2018) 1. Water Management & Conservation Water Management Responsible water use and waste water management plays an important role in events’ sustainability agenda. Where water scarcity is an issue, events must not overdraw on this precious natural resource. For events held in natural settings or at venues with close proximity to waterways and surrounding watershed, they must be protected from event activities 5 Source: Event Sustainability Management (Jones, 2018) 1. Water Management & Conservation Issues & Challenges Water Scarcity = when demand exceeds supply Ground water is contaminated or polluted (e.g. poor sanitation, illegal toxic dumping) Surface water quality is affected by agriculture, industry or urban impacts. Water supply is not evenly distributed or conveniently located (arid regions, water sources not managed) Climate change impact on water sources 6 Source: Event Sustainability Management (Jones, 2018) 1. Water Management & Conservation Water Management Considerations Water Supply How will water be supplied to the event/venue? How ‘energy intense’ is the water provision? Does water supply and wastewater require transportation by truck/tanker? Purpose of usage what is water used for during the event’s entire lifecycle? Water Source Protection Water intensity how ‘water intense’ is the proposed event, activity, site or venue? What is the ‘water intensity’ of attendees (per person per day)? Is the event held at a watershed (water capture) zone? Are there natural waterways or water sources that needs protection from event’s activities or contamination? Wastewater How much wastewater is produced from the event? How will wastewater be disposed? Are there chemicals/toxic substances used? 7 Source: Event Sustainability Management (Jones, 2018) 1.

Water Management & Conservation Water Conservation (reduce, use less) Following water conservation protocols or regulations is important when: It is predicted that the event will use a large volume of water Use of water at the event will draw an usually large amount of water from local water sources Livelihoods of surrounding residents (especially in rural areas) depends on water supply There is water scarcity at the proposed event site. 13 Source: Event Sustainability Management (Jones, 2018) 1. Water Management & Conservation Water Conservation at events can be achieved through: 1. The way water is used 2. The types of water devices installed 3. Manipulate/Control supply Water conservation techniques include:  Reducing demand – through use of water efficient fixtures and fittings such as lowflow nozzles, and sensors or spring-load return taps  Reducing demand through operational efficiencies and techniques  Limit water supply by not providing free flow on tap to prevent excessive use  Use of water management systems to detect leaks, or automate supply to devices (e.g. garden sprinklers)  Substitute demand through sourcing water from non-potable supply  Use of waterless options such as composting toilets, waterless urinals, hand sanitisers  Engaging and educating users to achieve water conservation goals  Reducing water pressure 14 Learning Outcomes 1. Water Management & Conservation 2. Water Use & Waste Water 15 Source: Event Sustainability Management (Jones, 2018) 2. Water Use & Wastewater Wastewater It does not matter if the event is held outdoors at a park, stadium, greenfield site or at indoor venues, the event will very likely use clean water and produce waste water. Events can produce large peaks of waste water. Capturing and re-using grey water is the ultimate wastewater management Source: Event Sustainability Management (Jones, 2018) 16 2. Water Use & Wastewater Water Use at Events Various types and stages of water supply span from provision of fresh drinking water through to handling sewage BEFORE TYPES OF WATER 1. Clear Water – for drinking only. Supplied from standpipes or from dispensing tanks 2. Blue Water – for washing, shower and other human activities but not suitable for drinking. Sources include bore water (drilled from underground), dam or river 3. Grey Water – used water (from washing) without organic contamination, When filtered, can be used for flushing or non-human contact activities 4. Brown/Black Water – Waste water from toilets or caterer washup, which is collected in septic tanks or transported to water treatment plants. AFTER 17 Source: Event Sustainability Management (Jones, 2018) 2. Water Use & Wastewater Water is used and wastewater is produced at events from various activities, such as:            Catering and food stalls Cleaning Toilets and showers Handwashing facilities Stand-pipes and free drinking taps Misting stations at hot and dry events Dust settling Ground preparations Gardens watering Vehicle or equipment washdown Inputs for construction or event activities 18 Source: Event Sustainability Management (Jones, 2018) 2. Water Use & Wastewater Wastewater – potential hazardous contaminants from water used at events include: Personal toiletries or products for shower and handwashing Toilet treatment products Cleaning products Catering wastewater Paint wash-up water Urination Source: Event Sustainability Management (Jones, 2018) 19 2.
