Cholera

The main reason for the outbreak of Cholera in London in 1854

London was down to awful sanitary systems.Imagine drinking water from a sewer, because this in fact was

what was happening. It started in Broad Street where the foul

water containing human solids and fluids (excrement and urine),

mixed with the drinking water which was being pumped from a

water fountain in the street. This was the source of the hideous

cocktail that poisoned the people of the city of London and led

to many deaths.

Sanitation problems around the world

Whenever there is a humanitarian crisis and wherever

there is a refugee camp there is often a problem with

disease and this is often down to poor sanitation

created by the mixing of drinking and foul waters.

A recent event in New Orleans in the USA created a

similar crisis situation for the residents where the

sewers overflowed into the streets.

Disease from foul water can be transmitted by

drinking it (waterborne) or by breathing in the

vapour (airborne).

This is why the Building Regulations stipulate

that the installation of sanitaryware must be

to the correct standard to prevent the ingress

of foul smells into a dwelling.

When we studied cold water we found that the WaterRegulations classified water in 5 different sections from 1,which is drinking water to 5 which is excrement, urine andpoisons.

The Water Regulations 1999 require plumbers to be approvedcontractors so that they can install systems and avoidcontamination of water as hot and cold water services areused in connection with waste and foul water. The BuildingRegulations require that no foul smells enter a building andthat sanitation installations do not flood or create blockages.

A Building Control Officer (BCO) (aka Building

Inspector), is now generally known as a Building

Control Surveyor in the UK.

Their main function is to ensure that the

requirements of the Building Regulations are met.

The local authority council will send such an official

to inspect newly installed sanitary pipework or evenbe present at the planning and design stage to

ensure the sanitary installation complies.
