storm water mgt.

talkin bout storm water mgt. nice video bout infiltration systems dat can help solve d problem f ground water depletion, can prevent flash floods, can prevent pollutants fr reaching our water bodies, etc.

rain water collection

A Shipot is a clean water source in many villa...

wen it rains….it pours….as dey say….w/ all d concrete pavement in the cities, d soil can no longer breath & rainwater goes directly to nearby water bodies 2gether w/silts thus groundwater aquifers r no longer replenished. if we all collect rain water then we can help minimize sudden flooding…..rain water collection is not only for pple who don’t have enough water, it’s a storm water management intervention!

in d phils. der is a law, designed to save rainwater during the rainy season in catchments or sumps, w/c was passed way back in 1989…..Republic Act No. 6716, the law that provides for the construction of water wells, rainwater collectors, development of springs and rehabilitation of existing water wells in all of the country’s barangays.

since wer only good in making laws & nobody cares bout storm water mgt….d 21 yr old rain water collection law just like other laws in d phils. was never successfully implemented….

now dat water is being scarce once again in metro manila, pple started 2think bout rainwater collections….most likely tis desire will soon die after water supply has been normalized….

storm water mgt. has many benefits e.g., safety, health & environment….but who gives a ????

nxt tme derz a flashflood……think bout storm water mgt!

porous asphalt pavement w/ recycled tires

According to the Philippine tire industry, the annual average volume of tires in the market is 6.7 million. Around 2.7 million are locally produced and 4 million are imported. Passenger tires account for 65% of the total tire market followed by truck tires at 30%. With very few recycling options, discarded tires will mostly end up on dumpsites.

Large scale recycling is the final step in the earth friendly disposal of scrap tires. Accordingly, the most promising way of recycling rubber is by turning them into ground rubber “crumbs” which can be added to asphalt. It then can be used for paving roads, running tracks, runways and playgrounds. Because of the mixture of rubber, the life of the asphalt pavement is expected to increase by four to five times. In 1989, 11 million kilograms of rubber (around 2.5 million tires) were converted into asphalt-rubber and used in 35 states in the US. This is a recycling process, which the Philippines can also explore.

here is a cool tire recycling technology that’s also good for a storm water management program coz it makes d asphalt pavement breathable..check out d video link bellow!

national climate outlook forum

yesterday, i attended d 33rd nat’l climate outlook forum by d philippine atmospheric, geophysical & astronomical service administration (pag-asa).  accordingly, d earthday flash flood last april 22 was an above normal one. d climatological normals 4d last 30 yrs, indicates dat d ave. rainfall 4d month of april is about 38 millimeters. while d rainfall data from april 1 to 23 already registered a high 105mm. tis kind of hard data can b used so dat ppl can plan 2mitigate d effects of flash floods or adopt 2tis recurring weird weather.

one scheme could b d implementation of ‘storm water mgt’ 4flood prone areas. one key activity (aside 4d usual drainage system cleaning) could b d rainwater collection 4bldgs. & other structures, tis can delay or minimize d  effect of rising flood waters in d streets. another one could be d mitigation of ‘heat island effect’ thru breathable open spaces or porous concrete pavements.

der r lotz of data dat r being generated by pag-asa….tis can b used 2inform ppl dat abnormal situations need drastic actions & solutions, not only just raising one’s awareness….

d status of dams in luzon area was also discussed (as in d past forums), der r lotz of information being monitored by d hydro-meteorology div of pag-asa. hope dat my suggestion 2evaluate d data re: rate of flooding of dams during rainfall can b used as environmental improvement indicator for d  dams’ watershed mgt efforts. der might b a lot of money being spent w/o actual improvements….comparing d environmental performance (e.g. watershed mgt programs) of d diff dams in d phils. can reveal w/c dam managers need 2b given appropriate recognition…..
