Q3: What can my business do to adapt to water scarcity?

For businesses seeking to become water resilient, GreenCape has developed a tool called the Sustainable Water Use Journey. The tool is designed as a methodology for businesses that can be seamlessly integrated into any existing business model in order to achieve water resilience in a logical manner. 

Sustainable water use journey

Figure 1: Stages in the sustainable water journey

 

  1. Understand water uses and risks
  2. Explore and adopt water efficiency interventions
  3. On-site wastewater reuse
  4. Access alternative water supplies

  

STEP 1. Understand water uses and risks

Measure > Assess Risk > Benchmark

Measure: 

Businesses can identify future water saving opportunities through measuring their current usage and respective purpose for use.

How To: Water use measurements can be performed through water audits, or use of smart (online) water meters and sub-meters. Smart metering is effective for leak and/or abnormal usage detection for rapid repair and water loss prevention.

Legislation and Free Assistance: Large water users (users of more than 10,000 kilolitres per annum) are required to submit an annual water audit to the City of Cape Town. The National Cleaner Production Centre (NCPC) offers free water audits for large commercial and industrial water users and smaller company groups.

Best Practice Examples: Growthpoint Properties reduced their water consumption at The Estuaries by 70% due to smart metering.

Assess Risk

It is important to understand and determine the water-related risks to your business and supply chain. Such risks include water supply, water pressure, water quality, and tariff fluctuation risks, etc.

How To: Businesses can access the following tools to help assess and understand their water-related risks:

Best Practice Examples:

  • GlaxoSmithKline (GSK): At GSK, 86% of the businesses total water volume is used throughout the supply chain, while only 3% is used in their own operations. Through value chain water-risk assessment, GSK have identified water projects for high impact through supporting farmers in India.
  • South African Breweries (SAB)SAB invested in an alternative irrigation system for irrigation of barley as a significant input across the full value chain. To offset their water use at the Ibhayi Brewery and Newlands Brewery, SAB has supported invasive alien vegetation clearing to prevent water loss

 

Benchmark

Once water use consumption has been measured and risk assessments are performed, further water use should be guided by industry best practice usage. The following benchmarking tools are available to business water users in the following sectors.

STEP 
2. Explore and adopt water efficiency interventions 

Once water usage is measured, and water saving opportunities are identified, businesses should implement water efficiency interventions. These typically include technologies, fittings, processes and behavioural interventions that are low cost and easy to implement with short pay-back periods. Examples of water efficiency interventions are listed below:

Water efficient fittings (easy to retrofit):

  • Hold-flush / dual flush toilets
  • Waterless urinals
  • Toilet cistern displacement products
  • Low-flow / mist tap aerators, or waterless hand sanitiser
  • Low-flow showerheads
  • High efficiency pre-rinse spray valves
  • Water efficient appliances (e.g. dishwashers, washing machines)
  • Automatic switch off devices / motion sensor devices (e.g. for cleaning conveyor belts)

Water efficient practices:

  • Fix leaks and faulty / leaking equipment & service equipment on a regular basis
  • On-demand flushing at the office (“If its yellow let it mellow, if it’s brown flush it down”)
  • Designated staff water champions and water leak reporting procedures
  • Optimise the operation of cooling systems
  • Sweeping or mopping floors rather than spraying down floors
  • Water wise gardening
  • Dishwashers and washing machines operated only when fully loaded
  • Staff training and guest awareness programmes

Efficiency Tip: Ablution facilities typically consume 30-50% of the total water use in domestic and commercial buildings. Therefore, these fixtures should be targeted for water savings measures, and are often low-cost or no-cost.

Best Practice Examples:

 

STEP 3. On-site wastewater reuse

The third step for businesses is to consider the reuse of wastewater onsite. The range of wastewater streams generated can be reused or treated for reuse.

Wastewater Categories:

  • Greywater: Relatively low contaminated wastewater from ablution facilities, kitchen facilities, laundries
  • Blackwater: Used water from ablution facilities, sewage

How To: Commercial and industrial businesses can explore opportunities for wastewater reuse with the following resources

 

STEP 4. Access alternative water supplies

Alternative water supplies provide businesses with an opportunity to augment their water intake requirements, significantly reduce water costs and ensure business continuity. Businesses can contribute to relieving pressure on municipal water supplies thereby increasing the drought resilience of the region. Alternative water supplies should only be explored once businesses have undertaken initial water efficiency interventions which will reduce volume requirements and project costs. 

Legislative and Supportive Resources: 

Types of alternative water supplies:

The following table lists the type of alternative water supplies, their corresponding legislation requirements, and best practice examples of their use:

 

Type of Alternative Water Supply

Description

Application Legislation/ Resource

Rainwater or stormwater harvesting

The funnelling, capture and storage of rainwater from non-permeable surfaces (eg. roofing, paving)

WRC CSAG Water Harvesting Tool

Water storage

Storing water as reserve supplies, especially during intermittent or disrupted municipal supply

City of Cape Town Water By-Law 2010: Requires businesses to store enough water on site to operate for up to 8 hours without municipal water

Groundwater use

Groundwater accessed through boreholes or wellpoints (varying in quality and treatment requirements based on intended use)

The National Department of Water and Sanitation (DWS) regulates groundwater use.

Maximum abstraction rates for the Western Cape

Map Link

For businesses:

High groundwater volume users: Most businesses will require a Water Use Licence in order to abstract groundwater and should apply through DWS’ electronic Water Use Licence Application and Authorisation System (eWULAAS) portal. The application process can take up to 300 days.

Low groundwater volume users: Businesses intending to use low volumes of groundwater may only need authorisation in terms of a General Authorisation (GA). In order to qualify for a GA, the user must comply with all the conditions listed in the relevant GA.

The City of Cape Town Municipality may also require registration or authorisation for certain activities (including registering boreholes)

 

For households: Households wishing to use groundwater for reasonable domestic use, typically fall under Schedule 1 of the Nation Water Act, and therefore do not require a licence

Treated municipal effluent

Municipal wastewater that has been treated in wastewater treatment works is known as ‘treated effluent’ (TE). TE can be purchased from municipalities (dependent on availability). TE is generally cheaper than potable water and is only suited for certain applications (eg. toilet flushing, fire systems, irrigation). TE can be treated to potable standards.

The City of Cape Town Application for supply of treated effluent


Q4: What are other Western Cape-based business doing to save water?

 

A: There are many businesses based in the Western Cape that have achieved significant water savings and are shown on  GreenCape’s Water Resilient Businesses webpage.

A: The Strategic Water Partnerships Network South Africa highlights water-related projects done by a range of stakeholders including: Anglo American, CocaCola, Eskom, Nestlè, SAB and Sasol.

A: The WWF-SA's Water Balance Programme links corporate water users to the health of our natural infrastructure through positive investment into critical catchments. These investments are used to clear invasive alien vegetation to balance the participant’s operational water use, as well as to mobilise the collective action necessary to ensure the sustainability of these interventions.

Q5: Where do I find a list of solution providers to assist my business with saving water?

A: A list of water technology and service providers can be found on the Western Cape Government’s 110% Green webpage.
