The referral point for Marathwada
Chhatrapati Sambhajinagar does for Marathwada what Nagpur does for Vidarbha. Jalna, Beed, Dharashiv, Latur, Nanded, Parbhani and Hingoli send their complex surgery here, and patients routinely travel 150-250 km to reach a theatre. That catchment shapes the brief more than the city’s own population does.
Two ecosystems sit side by side. The government medical college and its associated cancer and teaching infrastructure carry a large share of the district’s surgical load, with the occupancy pattern a public teaching institution brings — students, residents and observers in the room, and lists that do not shorten. Alongside it a private sector has grown into real tertiary capability across cardiac, oncology, neurosciences and orthopaedics, supported by the corporate health market the industrial base generates: the auto and engineering cluster at Waluj and Shendra, the AURIC node at Bidkin, and a substantial pharmaceutical concentration. Those insured workforces behave like an urban market; the rural catchment behind them does not. Most theatre projects here have to serve both.
Throughput, occupancy and the attendant question
When a patient has travelled 200 km, the case goes into a long list and the day gets used fully, which turns theatre turnaround into a capacity number rather than a technical footnote. Air change rate is the lever: a room at the 20 ACH minimum takes materially longer to return to its validated particle count than the same room at 28 ACH under a correctly sized canopy. The related decision is whether a second, smaller day-care theatre serves the catchment better than a larger main room, because much of the travelled-in volume is short and repetitive.
Occupancy is the second correction. Teaching theatres here carry eight to ten people in a major room, not five, and heat load and door-opening frequency need designing for the real number — under-counted occupancy is a common reason a room passes commissioning and then drifts out of specification at re-validation.
Attendants are the third, and they get treated as a facilities problem when they are actually an airflow problem. Rural patients arrive with families, and families accumulate at the nearest door to the person they came with. If that door sits on the semi-restricted corridor, the pressure cascade the whole ventilation design rests on is being opened repeatedly by people with no reason to be there. The answers are cheap at drawing stage: waiting capacity outside the restricted zone, one controlled entry point, a transfer bay that genuinely breaks trolley traffic, and interlocked hermetic doors.
Water scarcity is a facility-planning input, not a footnote
This is the variable that most distinguishes a Chhatrapati Sambhajinagar theatre from an identical one in Pune. The city depends on bulk supply piped a long way from the Jayakwadi reservoir on the Godavari, and delivery to many wards is intermittent and partly tanker-supplemented. Planning a theatre block as if water were continuous builds an availability risk into the surgical schedule. Four decisions follow.
Chiller and heat rejection. A water-cooled plant with a cooling tower evaporates roughly three litres per tonne of refrigeration per hour, plus blowdown at a quarter to a half again. A modest theatre-block load running twelve hours a day is several thousand litres a day, indefinitely, plus a Legionella management obligation. An air-cooled selection costs some efficiency and needs a ventilated, shaded plant deck, but it removes the water dependency entirely. In a water-scarce city that trade is usually the right one, and it belongs in concept design rather than in a vendor’s default selection.
Humidification. Marathwada is semi-arid, and through the dry pre-monsoon months a theatre can sit below the 50 percent relative humidity floor that NABH and HTM 03-01 set — an anaesthetic gas and static concern, not just a comfort one. The correct answer is a dry-steam humidifier, electrode or resistive, fed from softened or RO permeate, rather than an adiabatic or evaporative spray stage — adiabatic humidification uses more water and puts a microbial risk directly into the supply airstream. Even a dry-steam unit consumes meaningful water daily, so it belongs in the water budget from the start.
CSSD and sterile processing. Steam sterilisers require feedwater within defined conductivity and hardness limits, and washer-disinfector final rinses need demineralised water. That means an RO plant, and RO plants recover only 50-75 percent of what they take, so reject water is a real volume — plumb it to flushing, landscape irrigation or plant make-up instead of drain. Size the treated-water buffer for 24-48 hours of theatre and CSSD demand as separate storage from the general hospital tank, so a tanker delay cannot stop a list. At the point of use, sensor or knee-operated scrub taps with flow restrictors simply matter more here; an unrestricted scrub tap runs 8-12 litres a minute.
Semi-arid conditions also carry ambient dust, particularly near the industrial estates. Pre-filter and fine filter stages load faster than they would on the coast, so plan change intervals honestly and leave static pressure headroom in the fan selection. Protecting the H14 HEPA behind them decides whether the room holds its particle count between validations.
The engineering baseline
Twenty air changes per hour is the NABH and HTM 03-01 floor for general surgery, 25-30 ACH for cardiac, neuro and arthroplasty. ISO 14644-1 Class 5 in the surgical zone under the canopy and Class 7 at the periphery, through terminal H14 HEPA filters to EN 1822. A positive pressure cascade of at least 2.5 Pa per step from theatre to scrub to sterile corridor to dirty exit, held by pressure relief dampers and hermetic automatic sliding doors with bacterial gaskets. Fifty-millimetre PPGI or SS304 panels with PUF core, self-levelling antibacterial epoxy flooring with coved skirting, and ASHRAE 170 governing ventilation rates and room relationships.
Compliance and statutory notes
Private facilities register with Chhatrapati Sambhajinagar Municipal Corporation under the state nursing homes framework; government medical college and Directorate of Health Services projects run through their own works departments, with tender documentation worth confirming before design freeze. Fire NOC comes under the Maharashtra Fire Prevention and Life Safety Measures Act, 2006, read with NBC 2016 Part 4. Because so much of the Marathwada catchment presents under MJPJAY and PM-JAY, empanelment infrastructure criteria are a live design input, and the handover validation dossier — air change rate, particle counts, pressure differentials, microbial sampling, illumination and gas pressure records — is structured to lift straight into an empanelment or NABH file.
Delivery from our Pune base
The city is roughly 230 km from Pune via the Ahilyanagar corridor, about five hours by road, with a single day of transit for a trailer-load panel set. Survey teams reach site in three to five working days. Specialist trades — HEPA installation, hermetic door commissioning, brazing and validation — travel from Pune; general erection labour is engaged locally, which is part of why the cost base here sits below the state average. Pune is our only office.
