Filtration capacity to be raised
EVEN AS the Yeshwant Sagar spillway project awaits Central clearance work is set to commence on upgrading the reservoir’s filtration plant capacity from 15 to 25 million litres of water everyday with a reserve capacity of 5 million litres. Tenders for the project are to be invited on April 4.
Tender dates were finalised at a pre-tender negotiation meeting headed by Project Manager, Project Implementation Unit (PIU), Prabhash Sankhla on Tuesday.
Expected to be completed by January 2007 the Rs 73-lakh upgradation is being undertaken as part of the Rs 641.25 crore ADB-assisted Urban Water Supply and Environment Improvement Project (UWSEIP).
Boosting the filtration plant capacity by 10 million litres will result in an equivalent saving of Narmada water, at least during rains.
Something officials hope will help improve the water supply situation next summer. Apart from upgrading the treatment capacity of the 50-year-old filtration plant the project calls for large-scale renovation and repair. This consists of repairs including water proofing of roof, replacement of de-sludging valves, chlorinators and treatment pipes. And finally, installation of new compressors to improve aeration.
The meeting also gave the go-ahead for the purchase of 13 electromagnetic flow metres. The metres will be used for assessing quantities of water drawn, treated and supplied from the intake well at Jallud to the Narmada control room as well as on supply mains to bulk users. The mains meters would be hooked to power back up to tide over electricity failures.
While one electromagnetic metre would boast of 600 mm diameter the PIU has also mandated the purchase of 1,000 mm (3), 900 mm (2) and 500 mm (7) diameter electromagnetic meters.
In addition, the PIU will also invite tenders for 20 multi-jet meters for random testing of water flow in supply lines. The metres, ranging from 30-50 mm diameter, will be of the voltman type work metre.
