Water, drainage and services for a growing valley

How can safe, reliable water be secured without shifting costs or risk downstream?

Place-specific evidence and policy choices. A budget promise is not a completed service; older figures retain their reporting period. Proposed options and indicators below are for public discussion, not adopted government commitments.

How can safe, reliable water be secured without shifting costs or risk downstream?14

Updated 2026-10-13 · Version 1 · Sources · Change history

Question 1 What is the issue, and why does it matter?

The federal FY 2083/84 budget plans to complete the study for diverting the Yangri and Larke rivers into the Melamchi system and to extend pipe networks in parts of the valley (Rs 7.26 billion), and to start a 100 MW battery storage system in Kathmandu Valley to meet dry-season peak demand.1

The choice is how to improve outcomes in this province, who benefits first, and which institution can act. The figures below belong to the stated reporting period; they are not a real-time measure of today’s conditions.

Question 2 What do current law and policy say?

Water supply is a provincial and local service (Schedule 6, item 7; Schedule 8, item 19) and federal–provincial concurrent with sanitation (Schedule 7, item 18); human settlement and land-use policies are federal (Schedule 5, item 29); local development plans are local (Schedule 8, item 7).2

Disaster preparedness, relief and recovery is federal–provincial concurrent (Schedule 7, item 17), a local power (Schedule 8, item 20) and concurrent for all three levels (Schedule 9, item 9).2

Provincial executive power rests with the Council of Ministers. The Chief of Province (governor) performs constitutional and legal functions, generally on the Council’s recommendation and consent; the governor is not the department delivering these services. Provincial revenue and expenditure estimates go to the Provincial Assembly.3

Question 3 What is known, uncertain or disputed?

Known

The federal FY 2083/84 budget plans to complete the study for diverting the Yangri and Larke rivers into the Melamchi system and to extend pipe networks in parts of the valley (Rs 7.26 billion), and to start a 100 MW battery storage system in Kathmandu Valley to meet dry-season peak demand.1

The Finance Minister told the Assembly that the unrest at the start of FY 2082/83 had reduced business confidence, that the province had to spend time and money rebuilding damaged structures, and that price rises linked to the West Asia crisis had affected its finances.4

Uncertain

A province-wide number does not identify the worst-served wards or prove the same problem in every municipality. Before spending, establish a current local baseline, service quality, staffing, access barriers and the full operating cost.

Disputed

The policy choice is how to balance universal access, concentrated investment, affordability and fiscal sustainability. The alternatives below are Policy Nepal’s discussion options derived from the problem evidence, not claims that officials or parties have endorsed them.

Questions 4–5 What are the options, and what do they cost and achieve?

Options are listed in no particular order. Policy Nepal does not recommend one; real policies often combine them.

Repair and protect existing supplies14

Test water quality and dry-season yield, locate leakage and unsafe connections, and protect recharge areas before promising more extraction.

Benefits
  • Can improve reliability while protecting households already dependent on the source.
Costs
  • Testing, trained operators, metering and maintenance require continued finance.
Trade-offs
  • Lower abstraction or enforceable quality rules may raise short-term costs or ration supply.
What does implementation require?
  • Publish seasonal test results and service hours; prioritise unsafe sources and households without affordable alternatives.

Build shared supply and drainage systems14

Assess new intakes, storage, drainage and treatment jointly across affected municipalities, including source rights and long-term operating costs.

Benefits
  • Can address constraints that no single ward or municipality can solve alone.
Costs
  • Land, environmental assessment, construction, energy and operator finance must all be costed.
Trade-offs
  • Large schemes can create debt, displacement or downstream impacts if demand and consent are poorly assessed.
What does implementation require?
  • Disclose options and safeguards before procurement; fund maintenance and publish affordability support and grievance decisions.

Combining options

Start with a verified baseline and maintenance of functioning services, then test additional investment against the same outcomes. Publish who pays for capital costs, recurring costs and any household charges; an unfunded operating plan is not a sustainable solution.

Question 6 Who is responsible?

Shared
Urban services, water and drainage

Water supply is a provincial and local service (Schedule 6, item 7; Schedule 8, item 19) and federal–provincial concurrent with sanitation (Schedule 7, item 18); human settlement and land-use policies are federal (Schedule 5, item 29); local development plans are local (Schedule 8, item 7).2

Shared
Disaster risk and recovery

Disaster preparedness, relief and recovery is federal–provincial concurrent (Schedule 7, item 17), a local power (Schedule 8, item 20) and concurrent for all three levels (Schedule 9, item 9).2

Provincial
Chief Minister, Council of Ministers and Provincial Assembly

Provincial executive power rests with the Council of Ministers. The Chief of Province (governor) performs constitutional and legal functions, generally on the Council’s recommendation and consent; the governor is not the department delivering these services. Provincial revenue and expenditure estimates go to the Provincial Assembly.3

Question 7 What have parties and leaders said and done?

What was said or promised is shown apart from what was recorded as done. Every entry needs a dated source. A missing entry means the position is not established, not that someone opposes or is neutral.

This dossier presents official evidence and research options. It does not assign a position to a chief minister, governor, mayor or political party without a dated source specific to this issue.

Said or promised
