With the completion of pressure conduit work under CIDCO’s Hetavane Water Supply Scheme, it will be now possible to supply an additional 30 MLD of water to Navi Mumbai through Hetavane Water Supply Scheme. This has helped in streamlining the water supply to the nodes under CIDCO jurisdiction.
“Various measures are being taken by CIDCO to ensure smooth water supply in nodes under CIDCO jurisdiction. An additional 30 MLD water has been immediately made available from the Hatavane Dam, as CIDCO completed work of the pressure conduit in the record time of 15 days. This has definitely brought relief to the citizens as the water supply in the nodes under CIDCO’s jurisdiction has been improved. Apart from this, discussions are going on with Navi Mumbai Municipal Corporation, MIDC and Maharashtra Jeevan Pradhikaran to resolve the water issue.” Dr. Sanjay Mukherjee, Vice Chairman and Managing Director, CIDCO.
Water is supplied by CIDCO to Kharghar, Ulwe, Taloja, Dronagiri, JNPT Port, Dighode MIDC area from Hetwane Water Supply Scheme. Due to the development of various projects & mega housing schemes being undertaken by CIDCO in South Navi Mumbai citizens are now giving priority to these nodes for living. The demand for water is also increasing day by day due to the growing population in this node.
Water is being supplied in these nodes under CIDCO administered area through Hetavane Dam, NMMC’s Morbe Dam, MJP’s Palatganga source, Nhava- Shevha Scheme, and MIDC’s Barvi dam. The water demand for CIDCO jurisdiction area was 289 MLD but, CIDCO was getting only 259 MLD at the supply point with a shortfall of 30 MLD. Various short and long-term plans are being implemented by CIDCO to meet the growing water demand.
The Hetavane Water Supply Scheme which is the most important source of water supply, provides 150 MLD of water to CIDCO. CIDCO has obtained an additional quota of 120 MLD from Heatvane Dam which is sanctioned by the GoM Water Resource Department. In order to use the additional 120 MLD water storage, it is necessary to augment the existing Hetavane Scheme to 270 MLD which will require a time duration of 5 years.
However, to address the current water shortage, M/ s. Tata Consulting Engineers Ltd. (TCE) has been appointed by CIDCO as an expert consultant to explore the possibility of utilizing the available water resource and the recently completed underground micro tunneling as well as existing water supply infrastructure. TCE has been entrusted with the task of preparing a water augmentation plan for the maximum drawl of water from the Hetavane scheme.
In order to expedite the extraction of an additional 30 MLD of water, TCE recommended a long-closed pressure conduit instead of the existing open channel outlet. Accordingly, CIDCO has decided to connect the Hetavane Irrigation Canal Power Outlet (ICPO) to CIDCO’s water supply system through a pressure conduit. The design was prepared by CIDCO and received approval from Central Design Organisation (CDO), Nashik, and Water Resource Department (WRD), GoM. CIDCO has completed the work of the pressure conduit in a record time of 15 days and the pressure conduit is now operational since 6th June 2022. So it is now possible to draw additional 30 MLD water from Hetavane Water Supply Scheme.
The additional 30 MLD water reserves will help in streamlining the water supply in Kharghar, Taloja, Dronagiri, JNPT Port, and Dighode MIDC.
