Water Restrictions In Cape Town: What They Would Change In A Bellville Home

Water restrictions in Cape Town are not in force, and have not been since 1 November 2020, so nothing has changed yet in a Bellville home. That may not last the summer. The dams supplying the city stood at 74.0% on 19 October 2026, against 89.7% a year earlier, and the decision on restrictions follows the Department of Water and Sanitation's annual review, which meets on 2 November.

This guide from The Bellville Plumbers covers where that decision stands, the rules that already bind every household, what the City's published restriction levels and tariffs would change, and the plumbing worth sorting out before anybody declares anything. It will be updated once DWS or the City announces a decision.

Cape Town Water Restrictions: Where The Decision Stands

Two bodies can impose restrictions. The National Department of Water and Sanitation (DWS) has the authority to restrict all users of the Western Cape Water Supply System, the dams Cape Town draws from. It reviews that system once a year in an annual operating analysis in November. The department's Western Cape head, Ntombizanele Bila-Mupariwa, was quoted by EWN on 14 October as saying that this year's meeting is scheduled for 2 November 2026 and will "consider the need for the implementation of water restrictions should circumstances warrant such measures."

The City's own Water Restrictions Committee, set up in November 2025, can also decide to implement restrictions based on its own assessment. In September, EWN reported that the Mayoral Committee Member for Water and Sanitation, Alderman Zahid Badroodien, had warned that a department decision at the end of October may already be too late.

The City's figures explain why restrictions are under consideration:

• The dams stood at 74.0% in the weekly reading for 19 October 2026, down from 74.9% the week before. The same week in 2025 was 89.7%. The daily reading on 21 October was 73.8%.
• The threshold: "Typically, dam levels need to be 80% or more by the end of the rainy season to avoid water restrictions being implemented." The City called October the final month of the rainy season, and the dams have fallen every week since its 2 October update.
• Consumption: by 1 October the city was using 895 million litres a day, above its 860 million litre limit. That is the City's most recent published figure.
• Last summer's drop: the City says dam levels fell by about 40% over the past summer because of peak demand.
• The ask: household consumption needs to drop by at least 10%, through this summer and into next winter.

Badroodien's own advice in the City's 2 October update was that "our water saving efforts do not need to wait for a final DWS decision on restrictions." Until a decision is announced, the sections below describe what restrictions have meant before and what the City has already published for them, not what has been decided for this summer. No level has been named.

The Water-Wise Rules Every Bellville Home Already Follows

Restrictions sit on top of a set of permanent water-wise rules that apply across Cape Town. The City is explicit that these "are compulsory, even when there are no restrictions in place." In a Bellville garden or bathroom they mean:

• No watering between 09:00 and 18:00 with drinking water, and the same hours apply to borehole and wellpoint water.
• Hosepipes need a controlling device, a spray nozzle or self-closing trigger that stops the flow when released, and no hosing down of paving or other hard surfaces with drinking water.
• Pools must be covered when not in use, and automatic top-up systems on a float valve fed from the municipal supply are not allowed for pools or garden ponds.
• New and replaced fittings have limits: 6 litres a minute from a basin tap, 7 litres a minute from a showerhead, and no new or replaced toilet cistern above 6 litres.

The cistern limit is worth knowing before anything breaks. The City's water saving checklist notes that older, larger cisterns use 9 to 11 litres or more per flush, so a cistern that needs replacing anyway comes back using a third or more less water on every full flush.

What Each Water Restriction Level Would Change

The City's most recent published comparison of restriction levels dates from April 2020. Nothing on its site says a 2026 declaration would use exactly the same measures, or which level it would start at, so treat the table as a guide to the direction rather than a forecast. For households it sets out:

The pool conditions apply from the start: the pool must be covered with a solid cover when not in use, and backwash water and rainwater should be used for topping up where practical. Every level applies only to municipal drinking water. Rain, grey and borehole water are outside the restriction measures, though the permanent watering hours above still cover borehole and wellpoint water.

The pattern matters more than the detail. On this table a garden on drippers can still be watered at Level 2, when a sprinkler gets one hour on a Saturday, and a pool that is already full and covered is better placed than one that needs filling.

The Restriction Tariff That Comes With It

Restrictions are not only rules. The City's 2026/27 budget publishes three water tariff schedules. Level 1 is the lowest, no-restriction tariff that applies now; Levels 2 and 3 are higher tariffs for use during restrictions, and the Water By-law lets the City switch to these special tariffs when it restricts water. Which one would apply depends on what is decided. The table compares today's tariff with the Level 2 schedule, the first step up.

The rise is steepest where leaks live. Leaked water lands on top of normal use, so it is billed at the household's highest step, and sanitation is charged on 70% of it as well. For a stand-alone home using 15 kilolitres a month, a toilet the City would class as a fast leak, 13,000 litres a month, adds about R1,215 at today's tariffs and about R1,635 at the Level 2 tariff. Reading your water meter is the quickest way to know whether that applies to you.

The figures are for a stand-alone home on its own meter. Homes in sectional-title complexes are billed on the City's cluster tariff, so their totals will differ, though the direction is the same.

Lower Pressure Under Restrictions, And Why It Shows Up Uphill

The City says it reduces water pressure when restrictions are in place, to limit water lost through leaks and burst pipes. Its 2020 table keeps the targeted network pressure above 2.4 bar up to Level 2 and drops it to above 1.2 bar at Level 3.

Bellville would feel that unevenly. The town lies at an average of about 80 m above sea level, while Welgemoed, on the slopes of the Tygerberg, reaches 310 m. Water pressure falls with height, so homes near the top of a supply zone start with less in hand, and an upstairs shower or an instantaneous gas geyser that needs a minimum flow to light is where a drop tends to show first. In August and September 2026 the City was already working on a pressure reducing valve on the main serving Selborne Slot, Oude Westhof, Kanonberg and Van Riebeeckshof in Welgemoed, with planned shut-offs while the work was done.

Some demand is also being moved off the drinking supply altogether. The City's treated-effluent reuse pump station in Bellville, commissioned in March 2025, supplies about 4.3 million litres of treated effluent a day over a network of about 15 km. It is part of a citywide programme the City credits with saving over eight billion litres of drinking water a year.

Five Things A Bellville House Can Do Before Restrictions

None of this needs a decision first. These are the five places a household's water goes missing or gets wasted, in the order worth checking:

1. Find and fix leaks. A leak costs money now and more under any restriction tariff, because it is billed at the top step. Start with the 15-minute meter test; if the meter moves and you cannot see why, leak detection in Bellville finds it without opening walls on a guess.
2. Deal with the cisterns. A cistern that runs into the bowl is the leak nobody sees. The City's checklist also recommends directing cistern overflows outside the building, where they can be seen.
3. Fit flow restrictors that compensate for pressure. The City's checklist says aerators "don't necessarily reduce the flow" and recommends pressure-compensating restrictors, or aerators with integrated flow restrictors.
4. Check the pool. A float-valve top-up from the mains is already not allowed. If the level drops faster than evaporation would explain, rule out a leak while refilling is still allowed. A pool leak test is done with the pool full.
5. Keep rainwater and borehole water apart from the mains. If you add a rainwater tank or already use borehole water in the house, it must never be connected to the municipal supply. Have a plumber look at how it is plumbed in before summer.

If the meter test turns up a leak you cannot place, or you would rather have the cisterns and restrictors sorted before the decision, call The Bellville Plumbers on 087 813 4650 or use the form below.
