City’s ten-year water plan seeks to cut wastage

A WATER Conservation and Water Demand Management Plan which focuses on the next decade was presented at a meeting of the Executive Committee this week by deputy City Manager for Trading Services Philemon Mashoko.

The plan outlines steps the city will take to ensure a sustainable water supply up to the year 2027. Among these steps is the establishment of a first level response team to deal with water pipe bursts and leaks in record time.

The plan also deals with the security of water supply which, among others, includes financial sustainability, water quality, management capacity, water resources, including ground water, the reuse of effluent, dams, sea water and rainwater harvesting, water conservation, water demand management and infrastructure stability.

The broad objectives of the plan, according to Mashoko is to reduce non-revenue water to less than 20 per cent and reduce the annual water demand growth to less than one per cent. It also seeks to reduce unrestricted average domestic water consumption (wastage) by 25 per cent, and increase water reuse to 100M per day. It also includes the installation of meters on all water connections, by 2022.

“We will use the lessons learnt in the last ten years and avoid the mistakes made while maximizing on the interventions and methodology that yielded good results,” he said.

PLANS

A two pronged approach to water conservation will be pursued, namely demand reduction from the consumer side and demand reduction from the utility side, he said.

He outlined new targets for water loss through bursts and leaks from 30 per cent to 25 per cent in the next five years and 17 per cent by 2027. Water loss through inaccurage meters, billing errors and illegal connections is currently 10 percent, and the new target has been set at five per cent in the next five years and three per cent by 2027.

Targets on water losses through authorised unbilled consumption in rural ares, informal areas, RDP areas and fire fighting and tanker services has been set a five per cent in the next five years and three per cent by 2027 which would be an improvement from the current loss of 10 per cent.

FINANCES

In financial terms, benefits of the plan for the city include a R229m annual savings from loss reduction, a R1260m annual increase in billed revenue from metered consumption and R38m from the increase in sewer charges which will be implemented over ten years.

“Education and awareness campaigns, while ongoing, will be refocused and intensified. The installation of smart meters, valve control training and resizing of meters is still to commence while the replacement of aged meters will be intensified under the programme. The metering of informal settlements is very slow and a programme will commence soon while the metering of rural properties will also be intensified. Pilots of treated effluent reuse are underway and by-laws review will commence,” he said.

Mashoko said 68 000 water flow restrictors had been installed in the City to deal with the drought in the past year.
