WATER SUPPLY - Revisiting demand estimation approach

Please visit my web page "Urban Tenets" at https://urbantenets.nl/

************************************************

Flat assumption of Litre Per Capita Per Day (LPCD) water requirement as basis for residential water demand is most likely to give wrong estimate, error compounded by a)Fixed average household size considered b) multiple available choices for base year population like census, property tax records, existing municipal billing records c) randomised selection of population growth rate formula d) no consideration of water saving fixtures and appliances in the equation, e) no consideration of regional lifestyle peculiarity f) no consideration of water demand fluctuation over seasonal weather change cycle g) no consideration for emerging lifestyle changes

You will see why they pay little attention to such fundamental assumptions with this example. Have they revised per capita water requirement after covid Pandemic, hence the revised water demand at city level? Answer is "No", while no one failed to recommend that keep washing your hands frequently for instance. Imagine millions and millions of people suddenly started washing hands several times a day as a newly adopted lifestyle changes, some taking shower everytime they returned home from outside, but no thought given to accommodate likely changes in per capita water consumption due to same.

Further, are they going to revise Litre Per Capita Per Day number based on new lifestyle changes post Covid19 as citizens are likely to continue practicing good hygiene in future, adding more pressure on water demand. Likely answer is "No", but correct answer is that "they must revisit" LPCD number, including all other missed criteria as mentioned above.

Multi-criteria demand assessment and Agility are key to stay relevant when it comes to urban infrastructure planning.

Notion of good and bad Urban Streets -

************************************************

Notion of good and bad Urban Streets -sometimes it's mote than skill or fault of urban planners, urban designers, transport planners, road engineers and landscape architects! 

Broadly, there are only limited known ways a street can be designed from junction to junction, there are only finite ways street facade can be articulated and modelled. (Possibly 80% of street design work machine can do on its own, by running algorithm in near future) 

Then, what is the differentiator between a good and a bad urban Street design and quality of street experience? 

Some variables-

Outcome of Transport modelling

Quality of Development Control Regulations 

Compactness of neighborhood

Permissible adjacent Landuse 

Permissible Floor Area Ratio (FAR) 

Economic status of Neighborhood

Generosity of Landscape elements

Quality and thoughtfulness of Street furniture

Age of city neighborhood

Attractiveness of neighborhood

Locational context of street

Image and significance of city

You can see there more than 50% of variables from above list which are not in control of planners and designers; variables that influences and sometimes decides the ultimate outcome of urban street design exercise, and shapes the notion of street quality and experience.

Legibility of City by design not by labels!

************************************************

A case of many cities in developing countries and beyond.

Sense of getting lost and directionless in your own city can be a scary experience! More frequent is the phenomenon associated with planned cities compared to those towns and settlements which have evolved organically. Reason being several planned cities tend to get overwhelmingly repetitive in its modular spatial forms, sometimes making it unnerving during commute, while organically evolved cities usually boast multitude of visual cues and anchors to build a memorable streetscape.

Feeling disoriented or experiencing a sense of Déjà vu in a city is so common that people may repeatedly be unsure about correctness of path taken or exit chosen or flyover crossed on a daily basis on a routine path, as familiar as home-work-home.

Feeling of trapped in a maze is quite obvious and frequent a phenomenon in large residential neighbourhoods when it's sometimes difficult to orient yourself and finding an exit route seems a Herculean task, compounded by encountering random access gate closure.

It may take weeks or even months to actually being able to memorise or to get familiar with even frequented route, and then it's easy to forget again. It is clear that Legibility by labels or signage on its own and in all of it's collective forms, types and glory is certainly not being able to make a city legible in one go even for its regular citizens not to speak of visitors of city.

You cannot entirely rely on signage for navigation in a city, signage which are sometimes broken, sometimes vandalised, sometimes wrongly placed, sometimes unreadable by design, sometimes hidden from sight due to tree and plant foliage, sometimes owing to bad or no illumination. There are still only limited segment of citizens who actually or frequently are comfortable with or using or relying on GPS navigation maps and apps, and they who use such tools also encounter challenges like network connectivity, distracted driving.

Also acknowledging that a commuter driving a vehicle and continuously looking for signage and clues for direction is a potential threat on road due to lack of focus.

A careful attention and planning in terms of landscape variation and vegetation arrangement, landscape and urban design elements, lighting arrangements, architectural theme and design, facade articulation and zoning regulations, structural innovation etc. in combination with time tested and some better signage may possibly be the solution and attempt towards better legibility of a city!
