What prevents an urban or suburban community from developing an advanced integrated pond system?

not enough space set aside for a pond system.  Most urban/suburban settings are set up by developers for developers.  Ponds bring in 0 revenue.  There's no economic incentive to have a pond system.  It's all drain pipes and curb collections.  Also the maze of zoning regulations prevents integrated ponds as you'd require 1000's of easements to snake across across as many properties privately owned.  That's the short answer.

One reason maybe the pollutants that are in the areas that will be reflooded.  We do not know the impact they will have on the rest of the ecosystem.

Well all this is easier said t5han done because there are many issues involved. But on the face of it I think we need wider,more well maintained roads that are free from encroachments, we need to develop alternate sources of energy and all of us need to save water and  utilise it efficiently.

you need to tell us where this residential project is because geography is pretty important! Of course not less important is culture and customs where this is located! Otherwise if no restrictions exist and weather allows it then make lots of swimming pools and and lots of outdoor activities like  golf courses and tennis courts, having these features in your project plus a secure and environmentally clean atmosphere will enable the project to sell itself without much hassle...\n\nyou are welcome to contact me for further discussion

Dear Friend,\n\nIn the US, no business can operate without running water for purposes of sanitation.  More than a momentary disruption and you'd need to shut down.\n\nYour Friend,\nFrancesois

There is no grass in groundwater.  Groundwater is several feet under ground in most places.  The water table (the top level of groundwater in aquifers) holds water that many towns drill into and pump the water up in wells to use.  There isn't a lot of pollutants in the water because the soil cleanses the water on the way down to the groundwater.  The only thing that needs to be done to make groundwater drinkable (potable) in most cases is to soften it.  But, the bacteria do biodegrade (eat) a lot of the pollutants that do make it to the groundwater from leaks in storage tanks.  So bacteria do act as a natural defense to pollutants.

How about something dealing with providing potable water or water purification... that's a heck of a subject and there should be tons of information about it on the Internet.  Besides... with the fact that drinkable water is becoming harder to obtain and the costs are going up to provide that commodity, water science will be a real 'Biggie' in the near future.

They restrict the width of where the water can go. The narrower the area, the faster the flow.

Oh boy buddy, this gets really long & complicated, so I'll try to be as brief as possible.\n\nI assume that you DON'T want your property declared as wetlands, due to the fact that as soon as it is, the EPA and a whole bunch of other government TLAs (Three Letter Acronomins) step in to protect it.\n\nTechnically, the EPA states that a wetland can be anywhere where at least 1/2 inch of water has accumulated for a minimum of 30 days. \n\nTo verify if someone has designated your property as wetlands, you need to go visit several government, state and federal, agencies.\n\nFederal: US Geological Survey (USGS)\nEnviromental Protection Agency (EPA)\nArmy Corps of Engineers\n\nState: Whatever your state has for an equilivante for the fed EPA.\n\nBe warned, if you don't know if they've designated your land as wetlands, it's better to not ask. When you do, they WILL send someone out to look at it.

It depends on your source of water.  Rainwater, wastewater, pond water, and well water all go through different steps.\n\nThe things that need addressed in one manner or another are particulates (usually cleaned out by a filter in the beginning stages of the process), bacteria and larger life forms (also many of which can be be filtered out with finer filters), and chemicals (usually removed by reverse osmosis or by charcoal or some other cleansing chemical process).\n\nThere are a lot of sources out there.  I have listed a few of them below.  Good luck.

1. you need firstly to have a total density equivalent to that of fresh or salt water(for whatever purposed required)\nthen bouyancy will be stable/maintained \nthis will make a suitable start\n2. forge a shape suitable to make the sub hydrodynamic, this will enable the prototype to glige through the water \n3. have fun!

2 sources of water, Comets & Subterrerain.\n\nWhat % of ponds does not make a question.

Absolutely not. But there have been cases where subtherapeutic levels of fluoride have been added to the water, too little to do any good. Happened in my town.

no,  if your connected to city sewers you have to pay. check with your city councilman. they probably negotiated a billing delay when they were first installed. even if it was a city oversight. its a service you have to pay for. they charged me xtra sewer when i filled my pool and thats 6000 gal worth, even though it didn't go down the drain. if they can charge you they will. especially if all your neighbors are connected, they don't give you a choice.

Well, i was involved with some folks who were catching the rain off their rooftop in barrels, then using it to water gardens etc.  They had to modify the downspouts to go into the barrels.  Any way to catch, direct and store the water will work.

It is placed in the water to make the water safer to drink.  However, there is small towns who puts way too much in it.

It depends on the place where the ground is located.It is a very expensive process.Qualtiy turfs require underground drainage facilities and levelling.
