Landscaping in the Northern Cape

Kimberley's night-time shutdowns and your irrigation timer

Sol Plaatje Municipality has used nightly water interruptions to let Kimberley's Newton Reservoir recover. In October 2026, after a leaking valve on the 900 mm bulk pipeline at Droogfontein, supply was cut citywide from 22:00 to 04:00, and residents were asked not to water gardens, fill pools or wash cars during the repair weekend. In early 2025 a similar nightly cut ran from 21:00 to 04:00, alongside a daytime one from 12:00 to 17:00.

That matters for irrigation design. A controller set to water in the middle of the night will run while the supply is off, and the garden gets nothing.

• Set irrigation cycles for the early morning after supply returns, or for early evening before the cut.
• Consider a storage tank that fills when supply is on and feeds the irrigation by pump.
• Check the timer whenever the municipality announces a new round of cuts, because the hours have changed between rounds.

A larger fix is under way, slowly

Kimberley has a R2.5 billion programme to fix its bulk water supply. A pressure-management project under it cut network water losses by 27%, and a new 1,200 mm pipeline is being built to replace the ageing line behind the repeated failures. Until it's finished, plan a garden that can go a few days on stored water.

Plant for both extremes

Namakwa District's climate plan describes summer afternoons of 34°C to 40°C across most of the province, mild winter days around 22°C, and nights that often drop below freezing. A plant has to survive both, so ask your landscaper about heat and frost tolerance for every species on the plan, not just drought tolerance.

Rain falls mainly in summer across most of the province, but the west, including Namaqualand, is a winter-rainfall area and the coast gets only about 100 mm a year. In Springbok or Port Nolloth, autumn planting gets the benefit of the winter rain; around Kimberley, Upington or Kuruman, plant for the start of the summer rains.

Drought declared a disaster in Namakwa and ZF Mgcawu

The provincial government classified the drought as a disaster particularly in the Namakwa and ZF Mgcawu districts, after a dry 2024 summer and a below-average early winter in 2025, and it was declared a national disaster in February 2026. In those districts, assume lawn will be the first thing you can't water; keep it small or leave it out.
