Nagpur: The phase II rehabilitation work of the 37-year old, Seminary Hills Master Balancing Reservoir (MBR) Part –II which is known as ‘Heart’ of the city’s water supply system is going on in full swing by Orange City Water (OCW). Like our “Heart’ which distributes blood in human system, Seminary Hills MBR distributes water in city’s water supply system, especially to ESR’s of West , South West and Central parts of Nagpur.
It may be mentioned here the Seminary Hills MBR was constructed in 1981 and was not been repaired since then. Precious potable Water was going waste due to leakage from these MBR. Thus the rehabilitation of MBR was a must.
The Orange City Water (OCW) which has been operating and maintaining water supply system of city, took initiative and on priority basis successfully not only plugged leakages of 11.27 ML capacity Seminary Hills MBR Part –I by using ‘Pressure Grouting’ technique, but also saved thousands of litres of water going waste, through its rehabilitation process. OCW had successfully completed Part – I of Seminary Hills MBR and started distribution of water into supply system and now started work of rehabilitation of its Part- II part.
There are two MBR’s each of 11.27 ML capacity located at Seminary Hills (Part -I and Part II), which supplies water especially to West, South, South-West Central Nagpur. Earlier, the two MBRs which were interconnected and also connected to the Treatment Plants directly were isolated. The water is first supplied to these MBRs and then further supplied to the city.
OCW first isolated these MBR’s and shifted supply to one tank and the other tank was taken under rehabilitation. So that without affecting the water supply to the city the rehab work can be completed.
Further, like in a bid to provide clean and safe water at the tap of every consumer, OCW had started its annual ESR cleaning drive , in a similar manner , in a bid to save potable water going waste from old and leaking ESR’s (Elevated Service Reservoirs) the Orange City Water (OCW) which has been operating and maintaining water supply system of city, took initiative and on priority basis successfully not only plugged leakages on 11 major ESR’s of Nandanvan, Mini Mata Nagar , Laxmi Nagar (Old) Ram Nagar, Khamla, Subhan Nagar, Reshimbagh, Gayatri Nagar, Chinchbhuan, Sakkardara 1 & Sakkardara 2 (overhead tank), but also completed much awaited rehabilitation process of two major Master Balancing Reservoirs (MBR) like Seminary Hills part-I and Sitabuldi Fort (MBR).
It must be mentioned here, like OCW used latest ‘Pressure Grouting’ technique for rehabilitating Seminary Hills MBR. It is technique where series of holes were drilled through the concrete slab and wall of ESR, and a grout tube then inserted into each hole. Then a special chemical is pumped under pressure through each hole. The grout then displaced, compacted and solidified thus forming grout columns. Pressure grouting has now stabilised the existing concrete walls, slabs etc. these MBR.
