The Hyderabad Musi River plan involves intercepting and treating sewage before it gets into the river along a 34-km stretch from Bapu Ghat to Gowrelly. It creates part of the bigger MRDP, which aims to change the river from what is now akin to a drain into a working urban asset. For ages, the Musi's decline has been driven less by business than by the steady inflow of untreated domestic sewage through a network of nalas. The new plan looks to tackle this flow at its entry points.

At key junctions where nalas meet the river, interception and diversion planning structures will be installed to detain dry-weather sewage interception. The flow will then be redirected via gravity or pumping into a parallel setup of trunk sewer lines.

These mains will run along both banks, beyond the top flood level, to stay functional during the heavy rains. Officials explain the approach just: avoid the untreated wastewater from entering the river.

Despite of relying on a few large plants, the plan offers a chain of decentralised sewage treatment plants situated adjacent to the major nalas. These modular and compact units may be created vertically or underground, according to the space constraints in dense urban areas.

By curing wastewater closer to its basis, river pollution control focuses to cut down the pressure on centralised infrastructure and get better efficiency. The treated water will meet set environmental standards before reuse or discharge.

Water management project also involves comprehensive mapping using Total Station instruments, DGPS and drone imaging. It is about to ensure accurate and ground-verified designs.
