Can you drink the tap water?

Legally, yes. In Bulgaria, as across the EU, the European Drinking Water Directive applies; the tap water is monitored and generally drinkable. In practice Svetlana takes a pragmatic line and suggests two common routes. Either you buy drinking water in large canisters of ten or eleven litres, as many households along the coast do. Or you install a drinking-water filter on the tap. For fitting a filter, Svetlana draws on her network of local tradespeople. What makes sense in a given case depends on the location and the house. She discusses that best directly with buyers.
