Stormwater and Site Drainage
Surface water managed as a design resource — calibrated to local rainfall and snowmelt, not generic assumptions.
What’s included
- Site grading and surface water flow modelling.
- Surface drainage design to CPHEEO guidelines and IS codes.
- Permeable paving specification and subbase design.
- Stormwater retention, detention, and attenuation system design.
- Rainwater harvesting integration to meet bye-law requirements.
- Kashmir-specific snowmelt and seasonal runoff calibration.
Managing surface water responsibly is one of the most technically demanding aspects of landscape architecture, because poor drainage design produces failures that are expensive and disruptive to correct once a site is built out: waterlogging, erosion, and damage to both hardscape and planting. This service covers the engineering of surface water management across a site's outdoor spaces — grading, surface drainage, permeable paving, and stormwater retention or detention systems.
We design stormwater and site drainage systems in accordance with CPHEEO guidelines and relevant IS codes for surface water drainage, and principles of water-sensitive design that treat stormwater as a resource to be managed and reused rather than simply shed as quickly as possible — including rainwater harvesting integration, which is a mandatory requirement under many state and municipal building bye-laws in India. Drainage design is calibrated specifically to local rainfall intensity and, in Kashmir's case, snowmelt patterns, since generic drainage assumptions routinely fail to account for the region's specific hydrological conditions.
