Re: High water bill because of water pump

naku mas malaki babayaran mo kasi naka commercial line ka pala...parang nakaluxury car kasi category nun....di ba mas mahal rehistro ng luxury car kesa sa regular cars?ganun lang yun...hindi din tama magrequest ng another line pang residential dahil tancha ko mas lalaki ang bill niyo.

ilan ba kayo sa household at magakano average consumption (in cubic meters) at average monthly bills nyo?

we'll compare.

Re: High water bill because of water pump

Hope I can help. I work for Manila Water (not Maynilad).

I won't advise connecting your pump directly to your water service. If you pump directly, i.e. from the street pipe and there is a leak somewhere on the street mainline, air could get sucked in and your meter may read air together with the water, hence, you pay more. What's worse, if that leak is underground and in a wet area (usually is), you may suck in contaminants. Not very good for a dental clinic.

Best to have a cistern (ground level or below ground tank), even a small one, then pump from the cistern. That way, you can fill the cistern by gravity, i.e. through the normal flow from your service, then you can safely pump from there.

If you can afford it, you may even install an overhead tank (usually at the roof) so you can pump up from the cistern into the overhead tank at night, then enjoy water throughout your property all day without having the pump constantly turning on and off. Just size your tanks properly so you store just enough water for not more than one day's worth so that you still have good protection with the residual chlorine.

Re: High water bill because of water pump

Thanks po sa inyong mga reply.

@violaine

7 po kami sa household, nakaka 33 cu.m po ang consumption namin nitong last bill amounting to 2374.60.

i hope mabigyan nyo nga ako ng comparison kasi dito sa mga kapitbahay namin na naka residential lang. puro tig 100+ lang mga bill nila, mataas na yung 300-500 pesos per month kaya gusto ko lang ma verify kung bakit ganon kataas samin at kung pwede bang ipapalit namin ito sa residential rate kung pwede.

Matagal na po itong naka commercial rate kasi nasa business area daw.minana lang po namin ito kasi kanto din location nya at matao so no hindi po namin ginusto din magkacommercial

@Baralila

Maganda po yung suggestion nyo na overhead tank yun nga po ang nasa isip ko ilagay kaso yung dental chair nangangailangan ng pressure para gumana yung suction nya hindi ko po alam anong mechanics ng suction(saliva ejector) bakit kailangan nya ng water pressure para gumana so kailangan ko pa din ng pressure tank.anyway kung pang normal usage pwede na po siguro sa tank lang kami kuha.

Kung 7 kami sa household anong size po ng tank ang ma suggest ninyo? pwede ba yung mga best tank na stainless na upright i pwesto lang namin dito sa terrace sa 2nd floor kahit hindi na sa roof? bakit po kailangan na ang size ng tank yung macoconsumo lang sa isang araw?

Re: High water bill because of water pump

33 cu.m. is just about right for 7 people and a Dental Clinic. It's the commercial rate that is killing you.

Re: High water bill because of water pump

Hello blackswan,

I totally agree with sir balarila, if you can afford to install an overhead tank, like the stainless water reservoir from Bestank or other brands sold at hardwares or home depots, that will save you a lot of money in water bills and electric bills, though not much on electric bills. Maybe you could get a water tank that can storel water which will last you for 2 or 3days of use, maybe the initial expense will be high on purchasing a water tank, plus installation of piping and others but in the long run it will be worth it. 😉

Actually I don't like that electric pump constantly turning on and off several times a day just to have a water supply for the day, malinaw na gastos din sa kuryente. Have a short story to share, my wife's client a few years back lost their house due to fire because their electric pressure pump over heated while it was pumping water, the maids didn't know what to do then since the owners where at the mall that time and the children where in school. Some sad story loosing almost all of your belongings na napondar all your life, luckily nobody was hurt or died in that fire. :rolleyes:

In my case I have a large concrete water reservoir constructed that can store water for 4 to 5 days and a well pumped by a mechanical pump and an electric motor with 1.5 HP that runs for 3 hrs every four days.
Just simply installed large filters on the pipe installation for assurance to filter out some residue like sand, rust and other impurities.:eek:

Re: High water bill because of water pump

The pump does not directly affect the cost.. The rate per cubic meter is the problem.. In my situation we have a canteen, and a sari-sari store, although it does not really consume that amount of water the bill is high enough due to commercial rate..

The solution, we had another water meter installed.. And we use the water from the new line more often than the old one. Since the new line is categorized as residential rate, water is much cheaper..

It cost us around 8k to have the new water line installed. but in the long term its cheaper on the bills...

Re: High water bill because of water pump

Or you may also check for leaks. A small leak is magnified when pressure is added.

Re: High water bill because of water pump

Hi, sa experience ko po, check nyo lang kung may one way valve na nakainstall immediately after the meter. In theory, hindi dapat tumaas waterbill nyo kung lahat ng sinipsip na tubig nung electric pump will be stored in the reservoir in the house (electric bill lang ang tataas). Pero kung walang one-way valve, ung sinipsip ng tank mo na hindi mo ginamit, babalik sa system ng Maynilad. Lalo na kung ang storage nyo ay pressurized tank (kasi mas mataas na ung pressure ng system ng bahay nyo than ung sa Maynilad). So parang nagiging doble konsumo ng water kasi ung naipon na water na hindi mo immediately ginamit, babalik sa Maynilad. Hope this helps.

Re: High water bill because of water pump

@Blackswan Average lang ang consumption ninyo na 33 cu.m sa 7 household ang problema ang commercial rate mataas ang charges compare sa residential. sabi mo 33 cu m./ 2374.60 bayad mo bali 71+pesos/cu m.kung residential line yan less than 20pesos/cu meter lang.kahit na maglagay ka ng cistern tank & overhead tank malaki parin babayaran mo pwedeng mabawasan ng kaunti dahil sa pressure pero tama lang ang 33 cu m. sa 7 na member ng houshold ang magandang gawin mo kung pwede kang magapply ng bago residential line para sa bahay ninyo tapos sa dental clinic & tindahan nalang yong commercial line.

Re: High water bill because of water pump

Your paying a commercial rate for your household use.

Better to have a separate meter for your business and for your house. That's a logical thing to do.

There are many different solutions available depending on budget and your tolerance for maintenance. There are cementitious compounds, polyurethane and epoxy paints, etc. Some may need more frequent re-application than others. But best to consult some experts in this forum. Tank lining is beyond mine. Do some search in this forum as I recall there has been some discussion on waterproofing. Whatever you choose, make sure it is food-grade.

Re: High water bill because of water pump

@bala

yeah, it's the 'food grade' bit that's hard to decide upon. i have a concrete cistern tank which i'm rehabilitating. i found that it's original lining had begun to flake off, so i had scraped off.

the lining seemed to be paint-like. either latex or a epoxy (though don't know how epoxy would curl up and peel). the underlying concrete's smooth and undamaged, probably has sahara or something.

food-grade epoxy's the easiest choice in terms of safety. but the quotes i get vary from 4k to 40k, so independent research's mandatory 🙂

zepol, It may depend on whether you are stopping water coming in or getting out, so it may be necessary to water-proof both inside and out. (But if you can figure a way to water-proof the outside of the base please let me know.)
