Branched network of water supply and sewers (drinking water supply and waste water disposal), boiler houses with various capacities (heating and hot water) is created to deliver utilities to our country’s population living in cities and villages, apartment buildings and private houses, to small and medium-sized industrial enterprises and national economic assets.

In boiler houses gas-analysis equipment is used for solving the following tasks:

-        Continuous monitoring of carbon oxide concentration and of natural gas leakages in boiler houses with generation of warning alarm, emergency shutoff of gas supply and/or exhaust ventilation activation.

-        Continuous monitoring of operating efficiency of boiler plant by means of tracking oxygen content in exhaust gases;

-        Periodic adjustment of operation of boiler and burners performed in accordance with the content of O₂, CO (for boiler houses operating from natural gas), NO and SO₂ (for boiler houses operating from coal and mazut) in exhaust gases;

-        Periodic monitoring of gas fittings hermeticity and search for natural gas leakages;

-        Shutoff of gas supply in case of fire.

For housing sector and private houses the following gas-analysis equipment is used:

-        Continuous monitoring of natural gas leakages in the kitchen and shutoff of gas in case leakage is detected;

-        Shutoff of gas supply in case of fire;

-        Continuous monitoring of carbon oxide content in the garage and spaces where there are sources of open flame, e.g. fireplaces, with generation of warning audible and light alarm (ventilation activation – for garage);

-        Creation of monitoring systems for detection of natural gas leakages in apartments and in entrance halls of apartment buildings with automatic shutoff of gas in case of leakage detection and information output to the central control room (to housing maintenance office, facility manager and/or Emergency Control Ministry officer).

Natural gas supply to dwelling houses and boiler houses is performed by means of a branched gas network that serves for solving the following tasks:

-        Adding specific scent to natural gas (clean natural gas has neither smell, nor color) so that consumer could quickly and naturally (without use of special technical means) detect leakage. For this purpose an odorant (mercaptan) is added to clean gas; gas/odorant ratio (odorant concentration) must be monitored;

-        Control of natural gas odorization adequacy is performed by means of periodic inspections of the gas smell level in places of end use (apartments) and node points of gas distribution network;

-        Periodic monitoring of gas network integrity and search for gas leakages.

Organizations charged with operation of house plumbing systems use gas-analysis equipment for solving the following tasks:

-        Continuous monitoring of gas composition of the air in working area of sewage pumping stations. Usually it is necessary to measure pre-explosive concentrations of flammable gases and maximum permissible concentrations of CO, H₂S, seldom NH₃, in working area and also excess/lack of oxygen (O₂);

-        Continuous monitoring of maximum permissible concentrations of chlorine in working area of chlorination plants and chlorine storages;

-        Periodic monitoring of gas atmosphere during emergency repair and restoration service activities performed by plumbers descending to wells, chambers, reservoirs and collectors;

-        Periodic monitoring of activity of hydrogen ions (pH) in the water from the water supply point;

-        Periodic monitoring of oxygen dissolved in water of sewage disposal plant.
