Plumbing, Sanitary and PHE
We ensure that the water distribution system meets optimum performance parameters and the functional requirements of the installation. Water requirement is calculated on the basis of occupancy and area served, to plan storage tanks of adequate capacity. Pumping systems are selected based upon the best efficiency on the duty curve and the quality of water being supplied. In case of piping design, fixture unit method is used in accordance to national NBC and international (ASPE/UPC) standards. Soil and waste disposal piping is designed to ensure high standard of hygiene and reliability and to avoid exposure to occupants and unsanitary conditions. The two pipe drainage system is provided with anti-siphonage pipe to ensure high degree of safely and hygiene and to avoid foul smell entering the piping system and public areas through drains. The Storm or Rain water drainage system is based on the maximum rainfall intensity for the city. A separate and independent rain water drainage system is provided to collect rain water from roofs, balconies, planters, paved areas, lawns and roads. Rain water is then collected in rainwater harvesting pit with overflow connection to the nearest municipal water drain. In certain cases the rain water from roofs is collected separately and used for non domestic purposes such as washing of car parking areas, flushing etc. We give due design consideration to the placement of the stacks in the shafts and routing of pipes in the bathrooms, toilets, laundry and kitchens to ensure easy access and maintenance of pipes.
We plan the fire-fighting and fire-protection systems in accordance with national and international standards. Water is stored in underground fire reserve tank of the stipulated capacity, and is drawn using electrically driven jockey pumps, fire pumps or sprinkler pumps. All pumps have a separate suction line from the fire suction header. Delivery from the pumps is connected to the respective hydrant and sprinkler system, for which installation control valves with hydraulic alarm are provided in the basement. The sprinkler pump is isolated from the main discharge header by a no-return valve so that the hydrant pump can also act as standby for the sprinkler system. Services are delivered from conception to commissioning of each Project, enabling the Planner to arrive at an optimum design and installation for the following Engineering services.
- Sprinkler System (Wet Type, Dry Type)
- Flooding System (FM 200 and NAF SIII, Inergen, CO2 Flooding)
- Fire Hydrants (Wet Risers, Dry Risers)
- Fire Detection system (Manual Type, Automatic, Analog Addressable, Digital Addressable)
- Security Systems (Access Control, Intruder Alarm, CCTV Surveillance, Perimeter Protection, Fire Extinguishers)
Water & Sewage Treatment
We plan the water treatment in accordance with the total quantity of water that is required to be treated, the water analysis report of raw/source water and its ultimate purpose. The domestic water qualities parameters are considered in accordance to limit prescribed by the local codes. Various options for water treatment equipment include filtration units, softener Units, dozing Units, pH Correction or RO units. STP is designed to ensure that treated effluent characteristics are well within the permissible limits, even under varying flow conditions. The treated, disinfected waste water from STP is stored and reused for flushing, as make up water for cooling towers for air conditioners, DG sets and for external horticulture. The STP comprises of Preliminary treatment unit (Grease trap, bar screen, or equalization tank), biological treatment unit (based upon the treatment technology adopted for the project) and the tertiary treatment unit (Pre-filtration tank, sand filter, activated carbon filter or UV unit).
Rain Water Harvesting
The Modern methos of rainwater harvesting are categorised under two, they are Artifical Recharging and Rain Water Harvesting. The former is classified into Absorption Pit Method, Absorption Well Method, Well cum Bore Method and Recharge trench cum injection well. The later is categorised into Individual Houses and Grouped Houses which are further classified into Percolation Pit Method, Bore Well with Settlement Tank, Open Well Method with filter bed Sump and Percolation Pit with Bore Method.
