Proposed Industrial Shed, Gat No. 354, Navlakh Umbre

A proposed industrial development on a 13,196.22 sq m plot at Gat No. 354, Navlakh Umbre, in the Maval taluka of Pune district, with 8,564.41 sq m of construction. A large industrial shed - with eave gutters and a ridge vent along the roof to keep the air changing - sits on the plot with a G+2 office building built into it, roads along two sides, with space set aside for the transformer, a pump room and underground tanks near the entry. An industrial plot this size sheds a great deal of rain from its roofs and yards, and needs fire water on hand for the whole shed, so the external services are planned across the site from the start. The architecture is the architect's; our scope is the MEPF design.

We prepared the water calculations in June and the external services layouts in September 2026, revising them later that month to suit the site and again in October for the storm water levels. Water: the calculation takes 7,418 sq m of shed at 10 sq m a person - about 742 people - at 30 litres of domestic and 15 litres of flushing water a day - 33.38 kL a day; water comes in from the MIDC main, with a separate inlet for tankers, to a 25 kL domestic tank (enlarged from 20 kL in the first tank layout), and a working and a standby pump of 334 litres a minute fill the overhead tank. Fire: a 150 kL fire water tank, 3 m deep, beside the pump room, with a 1,620-litre-a-minute hydrant pump of 40 HP and a 180-litre-a-minute jockey pump of 5 HP feeding a 150 mm hydrant ring round the shed, single-headed hydrant valves with hose boxes, a tapping for the shed's internal system, three-way and four-way fire brigade inlets, and a two-way draw-out connection. Storm water: by the Rational Method at 75 mm of rain an hour, 7,482 sq m of metal roof and 5,714 sq m of paving shed about 255 litres a second at peak; eave gutters on the shed roofs with 160 mm downtake pipes and 150 mm half-round gutters at ground level, 300 and 450 mm yard gutters, and RCC pipes of 200 to 900 mm laid at their invert levels to the external storm water chamber - the main was upsized from 600 to 900 mm in the September revision, and the levels reset again in October. Sewage: 110 mm soil and 75 mm waste pipes from the toilets to RCC sewer pipes, 450 x 900 mm chambers and gully traps, a septic tank and a soak pit. The six sheets cover the combined external plumbing, storm water, sewage, water supply and fire hydrant layouts and the underground tank layout with its sections.
