Municipalities may use water treatment, wastewater treatment and air purification products for their owned buildings. Mechanical installations including domestic hot and cold water systems, closed circuit systems and in some cases cooling towers need the appropriate water treatment in order to operate under the optimum working conditions and ultimately minimize the maintenance costs. Mechanical installations should be protected against problems that may arise from the quality of the water used. These drawbacks include corrosion, scale deposition and most importantly microbiological growth. Municipalities are also responsible for in-house wastewater treatment to manage their domestic effluents. The running of wastewater treatment plants, pumping stations and grease traps consists of high costs if the maintenance is not done properly. The biological products in the domestic, municipal and industrial range can all be used in order to provide an enhanced, complete and environmentally friendly program that will minimize the maintenance costs but also enhance the running of the plant. Municipal buildings consist of vast communal premises such as restaurants, lobby, cafeterias but also kitchens and special refrigeration systems. The municipality is obligated to maintain a safe working environment for the personnel but also a healthy environment free of microbes for the public. This can be accomplished with the use of the appropriate solution from the air purification product range. Air purification machines and filters can be fitted according to the needs of every space in order to provide air free of microbes and unwanted volatiles. Municipalities can also promote the use of Similar Smokeless Cigarettes for both the public and personnel. In this way they will comply with the legislation but also provide a smoke free environment at their premises. The promotion of similar smokeless can also act as an economical incentive for the municipality as they will provide an added service to their customers but also create a new revenue stream for them.
