Utilities & Mobile Best Posts in Thread: Water Supply - Dumaguete City

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.

My neighbor and I had a spat over my dog injuring one of his chickens which flew into my yard. They demanded money for medicine?? I told them to take a leap. A few hours later they butchered the chicken for lunch, my dog only tore some feathers out of its @ss. Anyway I have two water lines going into my property and business. Both 1 1/4". sometime in the nite they cut out both the meters and threw them into the bushes. I called the DCWD and told them who I suspected and they went and checked their little squatter colony. 2 illegal connections,, very nice so that chicken dinner cost them. Now they get their water from the community pump which is around 150 meters down the beach ..

 

Unless you are going to build a tower high enough to gravity feed with enough pressure, you will need a storage tank, pump, pressure tank + plumbing / electrical connection. I would visit Polaris Engineering, Silliman Ave. Budget about PHP30000

 

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.

 

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

Just jump into a pedicab and ask.

 

I think a word is missing ?? If you meant, "Do you know if Polaris...," best to go there and ask. Unless you know Perry or any other contractor, my standard is, don't text, don't call, JUST DROP by, the town is not that big....

You should do a cost-benefit.. How old is the system, is it high quality or junk, was it well maintained, do you love it, maybe better and less stress if you install a new one in the new place and sell or ask higher rent for the old ?????

By the way, somebody complained about Noel. In defense of Noel, obviously I don't know the details, but did you and Noel sit down and design the system first, layout equipment, discuss pipe run, sizes, equipment pros & cons. Before we did our system, we had a two page initialed agreement, quote and sketches before anybody picked up a wrench. I have never done a house reno without it, even tho all my tools in the states were a "phone and checkbook." (slight exaggeration)
