Hairdressing salon

Hair and beauty premises with basin chairs, hair clog risk and small commercial drainage.

A hairdressing salon is a commercial premises offering hair styling, colouring and related services. Across Greater London, salons are present on every high street with concentrations in Westminster, Camden and Hackney. Drainage characteristics include backwash basin chairs with small waste branches, customer and staff WCs, and kitchenette or refreshment area waste. Common issues include slow drainage and blockages from accumulated hair at basin traps, chemical residues from colours and bleaches entering the foul drain, and grease build-up from wax-based hair products on waste branches. Operators should fit hair traps on basin wastes, arrange routine maintenance of traps, and avoid pouring excess colour mixes to drain. Trade effluent consent from Thames Water is generally not required for small salons, but larger establishments with extensive treatments should check requirements.
