Re: drainage system always clogged

I think your strategy is good ... unit dwellers should be responsible for this. You just need to put the necessary facility for them to be able to take care of it easily.

If it was me I'd make the individual unit screen mesh filter ( or whatever ) semi permanent. At least pag barado they know they need to clean from their side. It's important that they don't remove it as well.

Re: drainage system always clogged

Hey bro at least you know the cause of the problem, its the tenant themselves. May be you can talk to each head of the tenant kindly and politely, explain or discuss with them the problem at hand and try to find a win win solution for everyone. It will just take some discipline on every tenant to achieve the solution. Now if they don't agree to have a solution to the problem and would just think and care only for themselves, then maybe you can:

1.) go ahead with your plan of putting a fine screen to filter food debris in each drainage outlet.
2.) or just add some maintenance chores on your part every three months to clean the drain pipe so nobody complains of clogged drainage.
3.) or you can just replace your drainage pipe with a larger diameter, maybe 8" or 10" so that food debris or other basuras inside can easily be flushed out, bobombahim mo lang ng pressurized water hose palabas

To tell you the truth, its really a problem of apartment owners with several tenants, some are ok makisama, others walang paki alam sa ibang tao naman, minsan bababuyin pa yun unit ng apartment.

Good luck and hope you find a win win solution for all. :saiyan: :boxing1: 😀

Re: drainage system always clogged

If you do install strainers, go for the stainless type. Non-stainless steel will corrdoe quickly especially with all the gunk that people generally just dump down the drain.

You may also want to consider a grease trap. A bit more expensive but it may also solve some problem. If your tenants have the habit of pouring used mantika and taba down the drain, in time, these oily liquids will solidify in cold medium and combine with other food wastes. The grease trap may also trap some of the food waste.

Grease traps also are an environmentally responsible thing to do. Practically all condos I've seen install them. I just don't know how they collect and dispose the contents.

Re: drainage system always clogged

If you decide to go for the grease traps that balarila has suggested, better get them from Soler Street in Binondo.

The price difference between Wilcon/Home Depot and Binondo is well worth the trip.

Yep. When I built my house, I got finishing material every weekend driving my trusty Vitara sans backseat, filling it up with hardware. I saved at least 30% on finishing fixtures!

And I always left my car in those carpark vacant lots where you leave the key. I'd come back to the car with merchandise, get the key, load up, return the key to buy more stuff. I'd do this about 4x in a day and never lost a single thing in the car!

Re: drainage system always clogged

would a garbage disposal unit or sewer pump somewhere along the system do the job? i have similar problems: you'd be surprised at what tenants are capable of flushing down toilets.

Re: drainage system always clogged

The best approach is to put a small concrete settling tank..That is if its applicable to your current set up..Its like a small concrete tank under floor or reduced pozzo negro tank with maintenance cleaning hole cover. This will seperate solid to liquid u can remove the solids from time to time to prevent overflowed solids thus clogging system. This approached was very effective when i was working years back in a major paper mills. The pipe goin to plant`s treatment plant always clogged with solids residue so i try put series of settling square settling hole. With proper preventive maintenavce inspection and cleaning it was a success and no more clogging problem occured. ..

Re: drainage system always clogged

thank you sirs for all the replies/comments/suggestions

we did inform the tenants to not throw anything in the sink kahit gano kaliit kasi naiipon din sa drainage at nagiging cause ng bara kaya lang tigas pa rin ulo, hehehhe

as much as possible there will be no reconstruction or renovation, as for increasing the pipe size parang pinatagal lang namin yung magiging interval ng cleaning kung same tenants din na magtatapon ng basura dun, and yes yung mantika nga dun tinatapon tsk tsk

so i think the best way is yung lagyan ng wire mesh and after 2 or 3 months i-check then show them what they have deposited 🙂 pero i need the stainless one as suggested by sir balarila, sir any particular place i can get this one? meron ba nito sa mga hardware stores lang? at how much po kaya per meter?

salamat po ng marami sa inyong lahat

mukhang ok nga tong grease traps, kaya lang if they do not check/clean it periodically, is there a chance na pupunta pa rin sa drainage system yung mga fats at gunks? i believe this grease traps are sealed so ang overflow nya ay sa drainage din? and one thing, i have 2 kitchen sinks, isa sa loob at isa sa service area, so need ko 2 grease trap:eek: tapos by 5 units? 🙁

how much po ba ito sir sa binondo, estimate lang po for residential use.

thank you!

@ sir JayL, i will try sir to post pictures

Re: drainage system always clogged

update lang po mga sirs

last week e pinalinis namin at pinalagyan namin ng screen kaso after ilang araw lang barado na naman, so i checked it myself at barado nga.

yung proposed screen installation na sinasabi ko e hindi nagawa kundi gumawa ng parang open box at inilagay lang sa ibabaw ng mga tubo pero may dumi ngang nakuha, fresh kanin pa!:mad:

i have the pictures but im having a hard time retrieving it from my phone kaya gumawa na lang ako ng drawing.

yan pala yung drainage system ng 2nd unit ( ganyan din sa lahat ) at napansin ko e pantay ang placement ng mga pvc pipes kaya imposibleng malagyan ng screen yung galing mismo sa mga units so cancel ko na yung screen na solution. napansin ko rin na sobrang dumi at mabaho na dahil siguro dun sa mga dumi na dumikit na sa pipe, baka yung 4" na diameter e naging 2" na lang kaya mabilis magbara, paano na po kaya gagawin ko mga master for long term solution?

1. ang naiisip po namin e gawing open canal, para wala ng pvc at siguradong malaki na drainage system, ok po ba ito? mag aamoy mabaho po ba pag open canal? pero naka-slope naman po yung pagkakakabit nung mga pipes kaya wala dapat tubig dun sa canal, pwede po ba ito o may mas magandang solusyon?

2. for short term solution, buhusan ng liquid sosa or equivalent yung drainage system para matanggal yung mga tumigas na na dumi sa pipe para maging 4" ulit:D

3. short term pa din, ipalinis ng pressurized washer yung drainage system para tanggal lahat ng dumi, mga 300psi, matanggal nga kaya lalo na yung mga matitigas na na dumi?

4. meron po bang pwedeng ilagay sa p-trap ng sink para masala yung dumi? para pag puno na e hindi na magtuloy tuloy ma drain yung tubig at mapilitan silang linisin na yun? kung meron nito, gagawin ko ito after 2 or 3

patulong po sana ulit sa inyo, as much as possible e long term solution na po

maraming salamat po

more power to all!

Re: drainage system always clogged

sorry for the crappy pics, ito po yung sa 1st unit, puno ng tubig at may lumulutang pa

ito naman yung sa 2nd unit, sobrang dumi

Open canals are not sanitary if they continually have water. They become exposed breeding grounds for nasty stuff. If you want to consider this, you may want to make a canal (or box culvert) with removable concrete covers.

2. for short term solution, buhusan ng liquid sosa or equivalent yung drainage system para matanggal yung mga tumigas na na dumi sa pipe para maging 4" ulit:D

Is the pipe large enough in the first place? Not sure how large your apartments are.

Liquid sosa is always the best first step. But haven't you done this yet?

3. short term pa din, ipalinis ng pressurized washer yung drainage system para tanggal lahat ng dumi, mga 300psi, matanggal nga kaya lalo na yung mga matitigas na na dumi?

I know of a contractor who does high pressure jetting and pigging. Pigging is when you pull an object through a pipe to dislodge the muck the may have stuck on the pipewalls. Some pigs can have some reaming capability. Not sure if this option is too industrial and expensive for you but I can do a quick check in my office for their number.

4. meron po bang pwedeng ilagay sa p-trap ng sink para masala yung dumi? para pag puno na e hindi na magtuloy tuloy ma drain yung tubig at mapilitan silang linisin na yun? kung meron nito, gagawin ko ito after 2 or 3

All sinks should have P-traps and make it clear with the tenants that it is their responsibility to clean them.

BTW, your drawing of the box is actually almost like a grease trap. It is simply a box with the pipe inlet and discharge near the bottom but usually having more than one chamber or some baffle walls to let grease float and sediments sink. It should be large enough to allow sufficient time for floaters to float and sinkers to sink. Here's are nice illustrations.

While there are ready-made ones made of plastic, I'm sure you can also build one yourself.

But, as with any technical solution, you will also need to instill discipline on your tenants. You don't want to end up cleaning your grease traps every week because of dumped rice. P-traps on their sink would put the onus on them.

Re: drainage system always clogged

thank you sir balarila

yung drainage po ay designed to have no stagnant water, naka slope lang po sya all the way sa canal sa kalsada, though tingin ko parating may dadaan na tubig from sinks, washing machine and bathrooms so open canal e di pwede for health reasons 🙁

its a 5 unit apartment, 2 br, 1.5 toilet and bath with floor area of 52sqm per unit. yung size ng pipe for drainage is 4". kung waste water lang po ang dadaan e tingin ko sakto lang po pero pag sinamahan ng basura e maliit na. sinubukan kong buhusan ng isang timba ng tubig yung drain, hindi yung dahan dahan kundi biglaan na buhos at bumaba naman kaagad yung tubig. hindi ko pa po na-try yung liquid sosa as immediate na kailangang matanggal yung bara kaya sinusungkit ng bakal yung drain pipes, at pagkasungkit at natanggal yung bara, bababa na kagad yung tubig, minsan subukan ko pero sir, how long ba hihintayin for that liquid sosa to take effect?

i was thinking of the portable pressure washer na pang sasakyan lang :), uubra kaya yun? 🙂

as for the p-traps, para kasing tuloy tuloy din yung dumi from sink hanggang drainage e wherein dapat mapunta sya dun sa "p" nung tubo, how about yung bottle trap ba yun?

yes, we did show the "garbage" to the tenants and told them that it is the cause of the clogged drain, i hope hindi na magtapon ulit dun

dun sa illustration ko, hindi ko rin po masasabing parang grease trap kasi sir yung mga tubo nakadikit na sa flooring nung handhole kaya yung mga "sinkers" hindi nag si-sink kundi diretso na palabas as well as yung "floaters"

hahay ang hirap pagsabihan ng matitigas ang ulo na tenants 🙂

ang hirap pa ngayon tag ulan na, pag may bumara, baha yung 1st at 2nd unit
