Urban Water


Urban Water

The vast majo­ri­ty of the world’s popu­la­ti­on today is living in an urba­ni­zed envi­ron­ment and the trend of peop­le moving to cities con­ti­nues to grow. Thus a lar­ge pro­por­ti­on of human water con­sump­ti­on and was­te­wa­ter dischar­ge occurs in urban space.

Raw or trea­ted water, often sup­plied from remo­te sources, is fre­quent­ly stored in urban sup­ply are­as to ser­ve as a buf­fer at times of peak demand or inter­rup­ti­on of bulk sup­ply, befo­re being dis­tri­bu­t­ed to con­su­mers through (most­ly) pum­ped net­work systems.

For modern water dis­tri­bu­ti­on sys­tems, it is essen­ti­al to make water of suf­fi­ci­ent qua­li­ty, quan­ti­ty and pres­su­re avail­ab­le at all times. Today, sub­stan­ti­al water los­ses cau­sed by aging sup­ply net­works jeo­par­di­ze the sup­ply relia­bi­li­ty and incre­a­se the sup­ply cos­ts. ILF is com­mit­ted to working with cli­ents around the world to tack­le leaka­ge and employ the latest know-how in effi­ci­ent sup­ply con­cepts and tech­no­lo­gies to make the most out of the world’s pre­cious fresh water resources.

When it comes to collec­ting was­te­wa­ter, eit­her in dedi­ca­ted sepa­ra­te sys­tems or tog­e­ther with storm­water in com­bi­ned sys­tems, ILF can draw on deca­des of expe­ri­ence – be it for mas­ter plans, fea­si­bi­li­ty stu­dies or com­plex sys­tem designs. In addi­ti­on to the design of new sys­tems, incre­a­singly signi­fi­cant public and pri­va­te invest­ments tar­get the expan­si­on and reha­bi­li­ta­ti­on of exis­ting sewer sys­tems with the goal of maxi­mi­zing the use of avail­ab­le sys­tem components.

But Urban Water is not just about the human demand for pota­ble water and the resul­ting genera­ti­on of was­te­wa­ter, it is incre­a­singly about the manage­ment of rain water and spe­ci­fi­cal­ly extre­me sur­face run­off. Con­ven­tio­nal com­bi­ned or sepa­ra­te drai­na­ge sys­tems have for long suf­fi­ci­ent­ly addres­sed the cap­tu­ring and safe assi­mi­la­ti­on of this water into the envi­ron­ment. Howe­ver, the rapid expan­si­on of imper­vious sur­faces in com­bi­na­ti­on with the wide­ly obser­ved chan­ge in wea­ther pat­terns that has resul­ted in grea­ter rain­fall inten­si­ties and dura­ti­ons now neces­si­ta­te alter­na­ti­ve approa­ches. Hence, ILF is pro­mo­ting inte­gra­ted sur­face water manage­ment in urban envi­ron­ments – local ground infil­tra­ti­on, decen­tra­li­zed reten­ti­on in cities and safe rou­ting through urban agglo­me­ra­ti­ons. To this end ILF employs the latest 1D/2D cou­pled mode­ling tech­no­lo­gy to make urban space both safe and livable.
