The Mayor’s 401km Pipe Dream. Cape Town’s Pipes Don’t Fix Sewage

Cape Town mayor, Geordin Hill-Lewis recently posted that 401 kilometres of water and sewer pipes were installed in three years. The claim makes for a good headline, but it is a pipe dream if you think it solves Cape Town’s sewage problems.

Residents near the Diep River, Milnerton Lagoon and Khayelitsha still face sewer spills, flooding, and untreated wastewater.

Misleading Comparison

The Gauteng comparison is misleading. Cities there buy bulk water from Rand Water, which maintains its own pipelines. Those kilometres do not appear in municipal reports. Comparing them to Cape Town gives a false sense of performance.

Much of the 401km is routine maintenance, replacing old pipes or upgrading existing lines. Cape Town’s network is about 20,000km. Over three years, 401km is just 2 percent, or 0.67 percent per year. Engineers recommend replacing 1–2 percent annually.

Wastewater Treatment Works Struggle with Capacity

Replacing pipes alone does not solve pollution. Potsdam Wastewater Treatment Works and other plants like Cape Flats Wastewater Treatment Works and Zandvliet Wastewater Treatment Works struggle with capacity and compliance. Rivers stay polluted.

Cape Town’s Water & Sanitation. What the September Agenda Tried to Hide

Informal settlements see almost no benefit. Sewer spills there are caused by blockages, illegal dumping, stormwater, and overloaded pipes. New trunk mains do not fix these problems.

Numbers alone do not show progress. Pipes matter, but treatment plants, river health, and sanitation in communities matter more.
