Water supply disrupted

Water supply to almost all parts of the city except to the Fort Kochi region was disrupted till 2 pm on Thursday following disruption of power supply to Aluva Pump House.

Kerala Water Authority (KWA) officials said that pumping resumed by 2 pm on Thursday. “Pumping was disrupted due to power failure at KWA’s pump house at Aluva. As there was no power supply, water purification did not take place resulting in disruption of water supply to the city,” Kerala Water Authority officials said.

KWA officials said the problem was identified in the wee hours of Thursday. “A damage was detected in the cable end box on the line supplying power to three pump houses. The damage usually occurs due to the heavy moisture in the atmosphere. It was rectified by the KWA team by 1.30 pm and pumping resumed soon after,” officials of the Aluva Division said.

 

Get ready to pay more for water as BWSSB set to seek a raise

Get ready to pay more for water as BWSSB set to seek a raise

Get ready to pay more for water. The Bangalore Water Supply and Sewerage Board (BWSSB), which has not hiked the water tariff since 2005, although power tariff was increased at least four times in the last five years, will soon seek a raise.

The burden of electricity charges falls on the BWSSB as it pays nearly Rs 38 crore for power. Its earnings from bill collection are just Rs 40 crore to Rs 45 crore.

After increasing the water tariff to a flat Rs 19 per kilo litre for all bulk consumers, mainly apartment dwellers, in June 2013, the BWSSB is likely to send a revised proposal for water tariff hike to the government shortly, an official said on condition of anonymity.

The BWSSB pays Rs 27 crore to pump water from Thorekadanahalli (TK Halli), 100 km from Bangalore, in three stages. Besides, it spends money on pumping water within the City to various reservoirs, and the borewell charges.

The rest of the money is spent on staff salaries, operations and maintenance. The official said that the BWSSB had not paid borewell charges running into nearly Rs 100 crores since 2006. The Board has more than 12,000 borewells mainly in the fringe areas, of which nearly 8,000 are functioning.

According to the official, the burden of each power tariff hike falls on the BWSSB as it will have to pay more without getting anything in return. “Before the launch of the Cauvery IV Stage II Phase, Bangalore was facing a severe water crisis. Back then, the board could not think of increasing the water tariff, since there was already a crisis,” the officer explained. “But we spent more each time power tariff was hiked.”

Besides the frequent power tariff hikes, the BWSSB faces problems in mobilising new consumers for the additional 500 million litres of water per day (mld) commissioned in October 2012. Although the BWSSB has a capacity to pump 500 mld, it is pumping just 260 mld to meet the City’s needs.

In 2010, the government sent back the BWSSB’s proposal for a “reasonable” hike in water tariff. Three years on, the government is yet to take a decision.

The BWSSB runs on a ‘no profit no loss’ basis and just about meets the ends, its chairman, Gaurav Gupta, said.  “The board doesn’t get any revenue subsidy. The hike for bulk consumers was proposed around three years ago. We have been seeking an increase in water tariff, but the government is dillydallying,” Gupta told Deccan Herald.

Do not muddy the waters, says KWA

The Kerala Water Authority (KWA) has sought to allay fears of muddy water in the Periyar affecting the drinking water supply to lakhs of Kochiites from its Aluva pumping station.

Anitha C.O., assistant executive engineer of the head works section at Aluva, rejected reports that the turbidity level in the river had turned alarming. The maximum level was only 22 ntu (nephelometric turbidity units) on Wednesday. The turbidity level on Tuesday was 25 ntu. The level was brought down to the prescribed limits by adding water treatment chemicals in the water supply system to improve the quality.

Ms. Anitha said that water started getting muddier owing to the heavy rain. “We could ensure uninterrupted water supply even when the turbidity level went up to 100 ntu a month ago,” she said.

KWA officials said that removal of silt at the Kallarkutty and Bhoothathankettu dams would result in the discolouration of the Periyar in the coming days. Usually, the heavy discharge triggers a colour change in the river and water starts getting muddier, they said.

Continuous monitoring of water levels is progressing to check the water quality. Alum and lime are also used to bring the water quality level within acceptable limits. Efforts are also on to keep pH (the pH of a solution indicates whether it is acidic or alkaline) and turbidity levels within the permissible limits.
