Three Greater Vancouver Water District reservoirs (Capilano, Seymour and Coquitlam) provide 95 per cent of the water used in Delta. The remaining five per cent comes from Delta's three wells located near Watershed Park.
The Corporation of Delta's water system service covers an area of approximately 18,000 hectares, which includes North Delta, Tsawwassen, Ladner, Tilbury and Annacis Island. The water system provides safe, high quality drinking water to over 100,000 residents and businesses through a 580 kilometer distribution network, 40 pressure reducing valve stations and two pump stations.

A dike system surrounds the lowlands of Delta, protecting Ladner, the farmlands and other low-lying areas. The elevation of the Delta lowlands is between 1m and 1.5m, while high tides can be 2.0m.
