Project Partner Lalitpur Metropolitan City
Project Location Lalitpur
Project Duration Mar 2023 - Jun 2023
Description The initiation of this project to design the rajkulo from Dholahiti to Saptapatal pond in Lalitpur was driven by the
imperative to revive and safeguard the historically significant water conveyance system, known as the Tikabhairav rajkulo, with its origins dating back to the medieval period. The Saptapatal pond, apart from its cultural and social value, serves as a crucial water recharge aquifer. However, over time, the pond has faced challenges due to encroachment and neglect. To address these issues, the project seeks to preserve the rajkulo system. By channeling the No.1 rajkulo from Lele river at Tikabhairav to the Saptapatal pond through underground closed conduits (pipeline) along the proposed alignment, the project aims to ensure a steady supply of clean water to the pond. Additionally, a water treatment plant is proposed to be installed along the conveyance route to enhance water quality by removing impurities and contaminants. To undertake this engineering endeavor, a comprehensive study was conducted, including detailed surveys of the existing system, hydrological and geotechnical assessments, analysis of water discharge and quality, and the design of the rajkulo alignment and water treatment plant. As one of the flagship initiatives of the Lalitpur Metropolitan City (LMC), this project sets a precedent for the preservation and conservation of rajkulos and historical ponds within the region.
Objective
The main objective of the study is to prepare a detailed project report of the rajkulo from Dholahiti to Lagankhel.
The scope of the study is described below.
- Detailed survey of the rajkulo
- Profile design of the canal
- Investigation of the maximum available water quantity at the inlet of the rajkulo
- Preparation of BOQ and cost estimate
- Alternative alignment survey for rajkulo
