The South African Government has initiated a number of water conservation and demand management strategies taking cognisance of the fact that our Country, South Africa, is a water scarce country and that it is prudent to preserve this precious commodity and ensure that current and future generations are secured. However, it is not only the responsibility of government to conserve water, It is a shared responsibility that cuts across all sectors of the society, with government providing leadership.

The NWRS2 list 6 key Strategic Themes to achieve their set objectives:

1. Water resources planning, development and infrastructure management
2. Water Resource Protection
3. Equitable Water Allocation
4. Water Conservation and Demand Management
5. Regulation
6. Managing Water resources for climate change

Tsalano Business Solutions has developed a solution that aligns processes and procedures with the Six Strategic Themes of the NWRS2, in order to meet the objectives set out. Our approach to water conservation and management also takes into consideration the needs of the National Development Plan (NDP) in relations to job creation, Water infrastructure needs constant maintenance to keep functioning at optimum level and keep serving the needs of communities, with the support of the National government, local municipalities can employ people with adequate skills in this area. We have identified four key focus areas that water authorities need to pay attention to in order to achieve objectives of the NWRS2, and these are:

1. Infrastructure,
2. Technology,
3. Billing and Revenue Management,
4. Good Governance and proper processes.

Facts About Water Resource

"Research published by the Water Research Commission (WRC) in 2013 indicates that Non- Revenue Water (NRW) for urban supply systems over the past six years was at an average of 36.8%, which is equal to 1 580 million m3/a from a total urban consumption of approximately 4 300 million m3/a.

This research also indicates that in many municipal water supply schemes, the figures are even worse, with NRW in some cases up to 90%.The irrigation sector, which uses some 60% of the country's water resources, accounts for losses of between 35% and 45%.

A further study released in March by the Department of Water Affairs (DWA) in conjunction with the Water Research Commission (WRC) calculates that 1.58-billion cubic metres of supplied water is unaccounted for each year, which, at a nominal production cost of R4.50/m3, translates into yearly losses of R7.2-billion."

International findings about water losses;
  • 2007 was the first year in which more than half of the world's population lived in urban areas.
  • Water consumption is expected to increase by 40% by 2025.
  • Over 1.4 billion people do not have access to clean safe water.
  • By 2025, one third of the world's population will be affected by water shortages.
  • More than a third of the world's drinking water supply is lost from municipal distribution systems before it reaches the consumers.
  • Every year over $18 billion worth of water is considered Non-Revenue Water (NRW).
  • In many developing countries the percentage of lost water is well over 30%, reaching even 80% in extreme cases.
  • Every year, more than 32 billion cubic meters of treated water physically leak from urban water supply systems around the world.
  • Only 10% of leaks are visible; the vast majority of leaks cannot be seen above ground.
  • If we manage to reduce NRW by just one half, over 130 million additional people would have access to fresh clean water.

    National Water Resource Strategy 2 of 2013 outlines the following five core water sector Priority Focus areas;
  • Achieving equity, including water allocation reform.
  • Water Conservation and Water Demand Management.
  • Institutional Establishment and Governance.
  • Compliance Monitoring and Enforcement.
  • Planning, Infrastructure Development, Operation and Maintenance of Water Resources Infrastructure.
  • Systems High Level Overview

    Tsalano Business Solutions has designed and developed a GSM based Water Telemetry monitoring system (MIS) that is used to remotely monitor and control the levels, inlets and outlets water volumes monitoring along the water distribution network, power failure, pump statuses (on, off or tripped), water quality, water pressure, automated starting and stopping of pumps and also intrusion detection at all booster pump stations within the Municipality. The GPRS communications method will be used to transfer data between the Control Centre (cloud service) and the site devices.

    The solution consists of the Cloud service (Control Centre) that houses the server (Master Station), the GSM communications link and Remote Terminal Units (RTU's) or the site devices. The field sites are responsible for identifying, collecting, processing and transmitting all the site data to the Master station (Cloud) through the GPRS communications link. The cloud control centre software receives and further processes all information from the field sites and proactively warns the operators of any alarms so that appropriate actions can be instituted. Various reports will be created and made available to the relevant personnel on daily, weekly or monthly basis in real time.

    Our Solution is a Real-time Monitoring and Management of all water utilities and infrastructure within the Water Distribution Network. Real-time incoming mobility and System alarms from Remote Terminal Units, Smart Meters alerting of any deviation from the operational norms, changes in consumption patterns compared to historical data. Our Solution is fully integrated with these multiple streams and allows real-time data comparisons in a form of frequent reports, charts, dashboards for faster decision machining and analytics.

    High Level System Functional Overview:
  • Visual dashboards for critical process measures
  • Water Leakages/Loss Detection
  • Water Volumes Flow Readings, Monitoring and Reporting
  • Pressure Monitoring and Management
  • Quality Monitoring, Management and Reporting
  • Flow Rate Monitoring and Reporting
  • Water Level Monitoring and Management
  • Pumps Monitoring , Management (Automation) and Reporting
  • Pumps Maintenance Scheduling
  • Monitoring and reporting of Mains Power Failure
  • Remote Pump Control (Starting and Stopping)
  • Monitoring and Reporting of Plant Status
  • Detect Water Losses, Theft and Reporting
  • Minimum Night Flow Monitoring
  • Water Quality Monitoring within the Treatment Plants
  • Rehabilitation of Anaerobic Digesters
  • Rehabilitation of Oxidation Ponds
  • System Implementation Blueprint

    In Summary, Our solution allows the Water Authority to:

  • Ensure Alignment to the National objectives for water conservation as set out in NWRS2
  • Ensure coherence between DWA, Water authorities and communities through educational campaigns
  • Report on water usage and drive water conservation and water demand management programmes
  • Plan and allocate water resources equitably
  • Regulate water usage and water infrastructure
  • Drive water educational campaigns
  • Ensure water quality to align with Blue Drop and Green Drop Standards
  • Benefits of Implementing our Water Telemetry System

    Implementing and effectively using Telemetry system will enable municipalities to further realize the following benefits;

    Community Benefits:
  • Continuous and improved supply of water to residents;
  • Creation of jobs - NRW teams and construction teams;
  • Reinvestment of savings to benefit the community - parks, community centers, etc;
  • Positioning the municipality as innovative in promoting efficiency and sustainable environment;
  • Cost & Revenue Benefits:
  • Reduce costs by purchasing less water (Demand based sourcing);
  • Reduce costs by extending the lifespan of existing infrastructure;
  • Increase revenues by reducing commercial losses;
  • Defer investments in alternative solutions (treatment, desalination);
  • Environmental Benefits:
  • Reduce the use of too much chemicals needed to treat water;
  • Reduce the amount of water wasted;
  • Reduce the energy consumption required to produce and distribute water;
  • Reduce possible sink holes formations;
  • Discharge of quality effluent from the waste water treatment plants to the environment;
  • Reduction of dangerous gases such as Hydrogen Sulphide as waste water treatment plants;
  • Health Benefits:
  • Lower contamination resulting from bursts and antiquated pipes;
  • Reduce the risks of intermittent supply and poor water quality, which often lead to typhoid and cholera.
