The previous brief set out information from the 2018 General Household Survey (GHS) on the sources of drinking water and its quality. This brief will consider information on water supply interruptions, household perceptions on the quality of water services they receive, and the extent of household payment for water. It will also set out general conclusions from both briefs.
In cases where the municipality supplies water, the following questions about water supply interruptions were asked:

Water interruptions are extensive. 42% of households supplied by municipalities had experienced an interruption in the 12 months prior to the GHS. Of these, half had experienced an interruption lasting for more than two days and just over two-thirds had experienced water interruptions for more than 15 days.
Table 2 reports interruptions by geographical type. They are least severe in urban areas, though nearly a third reported interruption during the past 12 months. Interruptions on farms are worse than in urban areas. They are worst in traditional areas, with nearly 60% of all households reporting interruptions of more than two consecutive days and just under half reporting interruptions for fifteen days or more.

When it comes to municipal supply, many more households (5.7 million) have suffered from interruptions in supply than from unsafe or defective water (1.6 million).

Compared against the urban pattern:
Households were asked whether they regard their municipal water service as good, adequate or poor. Table 4 sets out the distribution of households across the ratings, by geographical type.

Nationally, 63% of households regard their municipally supplied service as good, and 11% as poor. The percentages in the good category drop from 70% in urban areas to 55% on the farms and only 29% in traditional areas. The percentages in the poor category rise from 8% in urban areas to 15% on farms and on farms and 26% in traditional areas.
The determinants of the ratings can be explored using regression analysis[1]. The results show a poorer rating if the water is defective, if there has been an interruption in supply in the last 12 months, if the household is in a traditional area, if there is piped water in yard, a communal tap, a neighbour’s tap, or a water tanker (compared with piped water in dwelling) , and in provinces other than the Western Cape (in increasing size of effect: (1) Gauteng (2) Eastern Cape, KwaZulu-Natal, Mpumalanga, Northern Cape and Limpopo (3) North West and (4) Free State). There is, however, a high level of unexplained variance, in part attributable to differences in criteria for rating between individual households.
It was reported in the previous brief that 82%of households had a water supply meeting the RDP standard of piped water in the dwelling, piped water in the yard or a communal tap within 200 metres from the dwelling. Two additional RDP criteria can be added: the water should be safe and there should not be interruptions in supply for more than 15 days in a year. Here ‘safe’ is defined as water which is not defective or water that is defective and not regarded as safe by the household.
Table 5 sets out the results of adding the two criteria. The national percentage of households meeting the RDP standard drops to 69%, varying from 85% in urban areas supplied by municipalities to 17% in traditional areas not supplied by municipalities.

Households which have piped water supplied by municipalities to their dwelling or to their yard were asked whether they pay for water. Table 6 sets out the responses. Just under half of all households who might pay for water do so, with 66% of households having piped water in their dwellings paying, compared with 17% of households having piped water to their yards.

Those not paying for water were asked for reasons why they did not. Possible answers were:
Some of the reasons for not paying are better than others. The non-payers are divided into the following categories:
Table 7 sets out the distribution of households across categories. It indicates that 42% of households not paying are doing so for adequate reasons, 16% because their water use is not measured or billed, 13% because households have low incomes. The remaining 29% fall into none of the three categories and they can be regarded as households which ought to pay, but don’t.

Interruptions to the municipal water supply are frequent, and often of long duration. As a source of dissatisfaction, they outweigh poor water quality in the perceptions of households. The interruptions attest to poor operation and maintenance of municipal water infrastructure. While the interruptions last, households are thrown back on using often unsafe sources of water, or they greatly restrict their use of water.
In general, household ratings of water services are rationally related to water quality, water interruptions, geographical type and water sources. Once these factors are controlled for, there remain provincial differences in water service ratings, with Western Cape and Gauteng the most favourable, and North West and Free State the least.
Adding water quality and water interruption criteria to the infrastructural components of the RDP water standard reduces RDP standard compliant households from 82% to 69%.
Just under half of households supplied by municipalities to their dwellings or yards pay the municipalities directly for water. There are good reasons for non-payment in many cases, but about 30% of households which do not pay do not have any of these reasons. Moreover, over 900 000 households do not pay because they have no water meter, or the meter is broken, or they do not receive water bills.
While there is more to be done in linking new communities and households to modern water infrastructure, there are limits to what can be achieved. Reticulating water to remote and low household density parts of the country may become prohibitively expensive.
As the construction of new infrastructure reaches its limits, improved water services requires better operation and maintenance and financial control. The value of infrastructure depreciates sharply if it is not properly looked after, and the picture which emerges from this study is that failure in this regard is widespread. Disorganized, and financially and technically weak municipalities cannot supply adequate water services, so that the water services problem and the local government problem are inextricably linked. At present, it looks as though the local government battle is slowly being lost. The Auditor-General’s 2017-18 Municipal Finance Management Act audit showed an overall decline in municipal audit results, with pervasive control and monitoring failures evident at a significant number of other municipalities across the country. Until this changes, no improvement can be expected in the picture of water services which emerges from the analysis of the 2018 GHS.
