Water distribution system in multi storeyed residential/commercial buildings ,Hotels ,Hospitals are very critical and important .Lot of emphasis to be given to maintain the required pressure in all the levels. These buildings have particular needs in the design of their sanitary drainage and venting systems. Water main supply pressures of 8–12 meters (25– 40 feet) can supply a typical two-storey building, but higher buildings may need different concepts and technology to have proper pressure booster systems using proper valves and techniques. We can’t rely upon only gravitational force.
Systems for boosting water pressure Pressure-boosting systems can be of several different types:
- pumping from a ground level or basement gravity tank to a gravity roof tank
- pumping from a gravity storage tank or public water main into a hydropneumatic pressure tank that uses captive air pressure to provide adequate drinking-water supply pressure
- installation of booster pump sets consisting of multiple staged pumps or variable speed pumps that draw water directly from a gravity storage tank or the public water main.
- Multistage booster pump sets typically include discharge pressure regulating valves to maintain a constant drinking-water supply pressure.
Drainage systems :
Complete Study of the drainage system required to the building and then designing proper piping and connectivity depending upon the gravitational forces etc.Locating the sewage disposal system in the vicinity of the building and connecting the building drainage disposal to the public sewerage system.
Adopting new technology to segregate the drainage and disposing the same in most effective manner.
Drainage system considerations In the drainage system for a multi-storey building, the drains from the plumbing fixtures are connected to vertical drain stacks that convey the waste and sewage to below the lowest floor of the building.
Alternatively, an approved vacuum drainage system may be considered.
Vacuum drainage systems In a vacuum drainage system, the differential pressure between the atmosphere and the vacuum becomes the driving force that propels the wastewater towards the vacuum station.
Vacuum drainage systems should be considered when one or more of the following conditions exist:
- water shortage
- limited sewerage capacity;
- where separation of black water and greywater is desired;
- where drainage by gravity becomes impractical
Hot Water System
Buildings such as hospitals, hotels, multiple dwellings and schools require large quantities of water to be heated, stored and distributed. Heating is usually carried out by a separate boiler, a steam coil or a heat exchange from a central heating or other system, and the temperature is normally controlled to within fairly narrow limits, 60 °C being an average temperature setting in some countries. Thermostatic devices should be installed to cut off the incoming heat source should the water in the storage vessel become excessively hot, and pressure relief valves should also be provided.
Considering all these aspects we undertake consultancy services in the following areas:
- Water supply distribution and treatment systems
- Estimation of water consumption and design of storage tanks
- Sewage Collection, treatment, disposal and reuse
- Rain water harvesting, treatment, disposal and reuse
- Storm water disposal
- Hot Water generation system( Solar, Heat Pump, Boilers, Geysers.
- Surface and subsoil drainage system
- Land scape / irrigation water supply systems.
- Solid Waste management.
- Equipment selection for the water distribution system
- Tanks and Pump Design
