Utilities & Mobile Water Supply - Dumaguete City

His name is Noel - really good guy.

 

Yep used him, good guy and he knows what he's doing.

 

I have purchased house near airport. Has a water tank on tower.
The water pressure is low. Told i need a tank dug into the ground and pump to pump water to higher tank. Is this best way and is legal? Thsnks

 

Normally figure 5 psi per 10ft of height. Most of the houses here are built with only 1/2" pipe so to get any kind of volume need to go to at least 20 ft tower. The problem then is there even enough city water pressure to fill the tank.. The solution I used is make and in ground tank and pump it up to the tank using a pool pump (submersible)

 

Water distribution is an infrastruction problem when every customer had a single story house or nipa hut along major roads regardless of whether you live In Dumaguete, Bacong or Sibulan. Water main sizes some but not all were based on future anticipated growth and as present farmland is converted to subdivisions the mains turn from a stream of water into a dribble even for one story houses.
The source of your water depends on where you live.
If you live in Valencia or Bacong your water comes off the moutain which is suceptable to mudslides and is gravity fed. Bacong has created a concrete holding tank at about 300 feet in Buntod, Bacong to improve water presure. My farm is along that road. During El Ninos past, Bacong used firetrucks to ferry water from Dumaguete then went along main roads filling jerrycans and buckets left along the roads for farmers and residents to have drinking water for washing and livestock.
Dumaguete wells and pumping stations require Norieco. If there is an extended brownout and the water system collapses a vacuum is created in the water mains which allows contaminated water from unrepaired water leaks to be drawn into the water districts system. Since there is no chlorination, when the power is restored the contaminated is mixed with the clean water. Stand pipes and elevated water tanks financed either by the water district or subdivision developers will allow customers in two story homes have a nice upstairs shower.
Sibulan's water comes from the Twin Lakes and is pumped downhill which requires Norieco, into an undersized infrastructure compounded by lax zoning that allow water consuming businesses to operate in residential areas. Sibulan like Dumaguete suffers from water system collapse in extended brownouts or calamities. Unlike well water, lake water has mosquito larvae that is sucked along with the lake water into the mains. In a bucket of city water these larvae clump together and form a mosquito which may have Denge that will float to the top and fly off. Proper chlorination would kill this larvae.
A new subdivision of hundreds of units, close to my house along the Bay Bay road has included a standpipe and water tank 50 feet in the air to store a abundant amount of water at 40 to 50 psi for their 2 story units. I wish the Sibulan Water District would do the same.

When Noel from CitiHardware installed a water system for us three years ago, the simplest for us was a 600L ground level metal tank, 3/4 hp pump and pressure switch, and 100L pressure tank. We are a two story house in pulantubig, near CityMall. Also depends on number of people in the house, we planned 3.

You can make the pressure tank smaller, but the pump will cycle more often. Since you have a pump, you really don't need the tank in the air, and the power outages are never long enough to drain the tank, so gravity really isn't essential. Since you have one, no need to change. IMHO, you do not need an inground tank.

We have never had a problem with city pressure being so low that a ground level tank wouldn't fill... Maybe it's obvious, but the pump pressurizes the water tank which is connected to the house water system. The pump has nothing to do with filling the 600L storage tank. If you keep the high tank, that might affect the design of the system if the high tank won't fill.

For an installer, you could use polaris also.

 

I had that man install the 1000L water tank, plus 1.5 hp and the the smaller .75 hp for the water pressure into the house, IMHO I wouldnt let him buy me a bottle of water , everytime he came he had a new plan, talk about a head wrecker, i have at least 10k to 15k in spare parts, between pvc pipes, taps, bends, brass this brass that and other stuff that he put together using the melter, then he took it all back out, so all that is useless too, go straight to polaris, do yourself a favour, they are the professionals, they can see the best set up without even getting out of the van, thats what you are paying for "experience and knowledge", save your self a bundle in the long run

 

what condition is the water tank on the tower

 

This might be a bit off topic but i recently found out a big difference between water suppliers in the UK and here.
We have a drunken lunatic in our neighbourhood that thinks its good fun to chop up water pipes, as they are above ground and made of plastic its quite easily done.
My closest neighbour and ours were both done on the same night, our neighbour is a filipino so nice to see the lunatic is not just out to get foreigners.
In the UK the local water board are responsible for the water supply pipes until it is inside your property, not so here.
That means i have to pay for the repair its more fun in the Philippines....
