Septic tanks and drainage in Cape Town
Cape Town has an extensive sewer, but off-sewer areas are many: Kommetjie, Noordhoek, Hout Bay's upper slopes, Philippi horticultural area, Joostenberg and the Atlantic coast farms rely on septic tanks and conservancy tanks. Sandy soils on the Cape Flats mean a high winter water table, so soakaways flood in the wet months and sealed tanks are common. Granite and shale on the mountain slopes can need rock breaking. Industrial areas such as Montague Gardens and Paarden Eiland use grease traps and conservancy tanks. Honey sucker operators serve the metro from Epping, Montague Gardens and the Cape Flats, and portable toilet hire is busy at events.

Typical french drain requests in the area come from:
- Houses: a trench for a septic tank at an older house, or a stormwater drain along a damp wall
- Estates and complexes: stormwater french drains around units and communal gardens, with septic trenches where off-sewer
- Restaurants, shops and offices: stormwater trenches for parking and retail frontages, and septic trenches for rural shops
- Factories, mines, sites and events: drains on yards, depots and building sites where runoff would otherwise pond
- Smallholdings and plots: a longer septic trench on a smallholding, plus drains that carry runoff off the yard
- Lodges, guesthouses and venues: larger trenches for peak guest loads and drains that keep paths and decks dry
- Farms and game farms: septic trenches for homesteads and drains that protect buildings and roads from runoff
- Schools, churches and clinics: long trenches for school and church septic systems, and drains keeping playgrounds dry
