Mechwat Technologies successfully executed specialized water, sanitation, sewage-treatment and wastewater-recycling works for the prestigious ITC Narmada Hotel project in Ahmedabad, Gujarat.
The main hotel construction project was awarded to the Shapoorji Pallonji Group, under whom Mechwat was engaged to provide water and sanitation solutions for both the main project infrastructure and the temporary facilities required during the hotel’s construction.
Mechwat’s responsibilities covered two critical project stages:
- Water, sanitation and wastewater-management facilities supporting the permanent hotel development.
- Temporary water and sanitation infrastructure for the labour colony, workforce accommodation and construction camp established during the project execution period.
The project commenced in 2016 and Mechwat’s assigned scope was completed in 2021.
This multi-year assignment demonstrates Mechwat’s capability to support major EPC contractors and construction companies with integrated solutions covering the full project lifecycle—from temporary construction-site sanitation to permanent wastewater-treatment and water-recycling infrastructure.
Project Background
Large hospitality developments require extensive civil, architectural, mechanical, electrical, plumbing and environmental infrastructure. In addition to the final hotel facilities, the construction phase may involve hundreds of workers, engineers, supervisors, contractors and support personnel operating from temporary camps and labour colonies.
Such project sites require dependable systems for:
- Drinking and utility-water management
- Safe toilets and sanitation facilities
- Sewage collection and treatment
- Wastewater recycling
- Hygiene management
- Prevention of groundwater and soil contamination
- Responsible management of wastewater from temporary settlements
- Compliance with project health, safety and environmental requirements
Mechwat was engaged under the Shapoorji Pallonji Group to address these water and sanitation requirements through project-specific technical solutions.

Mechwat’s Scope of Work
1. Labour Colony and Construction-Camp Sanitation
During the construction of ITC Narmada Hotel, Mechwat provided water and sanitation solutions for the labour colony and temporary construction camp.
The facilities were developed to support the day-to-day sanitation requirements of workers, contractors, site personnel and support teams throughout the construction period.
The construction-phase scope included solutions related to:
- Temporary and semi-permanent toilet facilities
- Bio-toilet systems
- Sanitation infrastructure for labour accommodation
- Sewage collection and treatment
- Wastewater-management arrangements
- Water-treatment support
- Treated-water recycling and reuse
- Hygiene-oriented sanitation planning
- Site-specific installation and technical coordination
- Support for changing workforce and occupancy requirements
These facilities helped maintain hygienic living and working conditions during the construction phase while reducing the risk of untreated sewage discharge around the project site.
2. Bio-Toilet Systems
Mechwat provided bio-toilet and biological sanitation solutions suitable for temporary project facilities and construction-site applications.
Bio-toilet systems can help manage human waste through biological treatment while reducing dependence on conventional sewer connections, particularly where permanent underground drainage infrastructure is unavailable or still under construction.
The solution supported:
- Improved sanitation for labour camps
- Safe management of human waste
- Reduced direct discharge of untreated sewage
- Lower environmental contamination risk
- Flexible deployment during different construction stages
- Improved hygiene and dignity for the project workforce
3. Sewage-Treatment Facilities
Mechwat supported the development and execution of sewage-treatment infrastructure for wastewater generated from the hotel project and its associated temporary facilities.
The treatment system was designed around project-specific requirements and intended to assist with:
- Collection and treatment of domestic sewage
- Reduction of organic pollutants
- Reduction of suspended solids
- Odour management
- Improvement of treated-water quality
- Responsible discharge or reuse
- Stable operation under variable wastewater loads
Construction camps and hotels can both experience significant variations in sewage generation. The treatment approach therefore required flexibility to accommodate changing occupancy, workforce strength and operational patterns.
4. Wastewater Recycling and Reuse
Mechwat incorporated wastewater-recycling provisions to improve the overall water efficiency of the project.
Subject to the approved treatment quality and project requirements, treated wastewater could be considered for suitable non-potable applications such as:
- Landscape irrigation
- Toilet flushing
- Construction activities
- Floor and utility-area washing
- Dust suppression
- Site cleaning
- Greenbelt development
- Other approved service-water requirements
Recycling treated wastewater helps reduce freshwater consumption while supporting more sustainable construction and long-term hotel operations.
5. Associated Water-Treatment Facilities
Mechwat also provided solutions related to water-treatment requirements arising during the project.
Construction camps and labour colonies need reliable water for drinking, cooking, bathing, washing and other daily requirements. The treatment configuration was planned according to available source-water quality and intended application.
The associated scope included project-specific support for:
- Water-treatment planning
- Equipment and system configuration
- Utility-water management
- Water-quality improvement
- Storage and distribution integration
- Coordination with plumbing and civil infrastructure
6. Permanent Hotel Water and Sanitation Infrastructure
In addition to temporary labour-camp facilities, Mechwat supported water and sanitation requirements associated with the permanent hotel development.
Luxury hospitality properties generate wastewater from multiple sources, including:
- Guest rooms
- Restaurants
- Commercial kitchens
- Banquet and event facilities
- Laundry operations
- Staff areas
- Housekeeping activities
- Toilets and washrooms
- Landscaping and utility operations
Mechwat’s integrated approach helped support the safe treatment and responsible reuse of wastewater generated across the project.

Project Execution Approach
Requirement Assessment
Mechwat assessed the water demand, sanitation needs, sewage-generation patterns, workforce requirements and construction-stage conditions before planning the systems.
Temporary Infrastructure Planning
Sanitation and wastewater facilities were configured for the labour colony and construction camp, considering changing site layouts, workforce strength and temporary utility arrangements.
Technical Design and System Selection
The appropriate sanitation, treatment and recycling systems were selected based on site conditions, wastewater characteristics and project requirements.
Coordination with Shapoorji Pallonji Group
Mechwat worked under the Shapoorji Pallonji Group and coordinated its activities with the wider construction programme, project management team, civil contractors, plumbing teams and MEP agencies.
Supply and Installation
Equipment, treatment systems and sanitation facilities were supplied and installed according to the approved project requirements and site schedule.
