Where We Are

Region C is a water planning area in North central Texas. It includes Dallas and Fort Worth, as well as 12 of 20 of the fastest growing communities in Texas.


Region C consumes more water per capita than any other of the 16 regional Water Planning Areas. 

Population in the 17-county area is projected to increase 250% between 2000 and 2060.

Total capital cost of proposed water supply measures: $13.2 Billion

Parts of region C are approaching physical scarcity for fresh water supplies.

The EPA estimates that 8% of all energy used is for the cleaning, pumping and heating of water. 

We see a potential conflict as a result of  increasing water demand, physical scarcity of fresh water and rising energy costs. The result is a situation where water may no longer be an inalienable right but a right we must pay for: Pay dearly for.



The Current System

The current system treats all water to a potable state although less than 10% of all water used in the region is used for cooking and drinking. Additionally, all water is used only once and then FLUSHED as though it were waste.



Pipelines Across TEXAS!?!

To supply enough water to this growing region at the current consumption and wasteful processes we must create new lakes outside the region or pipe in water from outside the region.


The plan as proposed by water planners in the state of Texas will require over 900 miles of uphill pipeline and the creation of 3 new reservoirs to supply Region C with the water it will need ion 2060.

Three new reservoirs are proposed for Region C: Lower Bois d'Arc Reservoir, Lake Ralph Hall, Marvin Nichols I, and Lake Fastrill. In addition, Marvin Nichols I, is proposed in Region D primarily to supply this region's projected needs.

Consequences arise from our current system of supply that are not unavoidable.

We see problems of Equity, Ecology and Energy.


What water?

 We propose a system that captures rainwater, storm water runoff and gray water, including air conditioner condensate.


Development Typlogies

 The growth forecast for North Central Texas will require a substantial amount of new shelter to be built. We recognize Transit District Development as the development with the most capacity to handle this growth. Transit Districts are transportation and land use systems. Water systems are most cost effective when designed from the ground up and system based. Therefore we couple these ideas to create our Transit District Gray Water Cycles.  


Transit District Capacity Analysis

Demographic, Market and Transportation trends come together to support over 2/3 of the growth forecast for North Central Texas through 2060.


Gray Water Loop

The Gray Water Loop separates gray water from black water, sends it to a local Waste Water Treatment Plant for cleansing, and rather then putting the water back into the river, it  sends the Gray Water back to the end user via a Purple Gray Water Line for Reuse. Water reuse eliminates the need for costly water infrastructures outside of Region C.

Transit Water Cycles are Gray Water Systems installed with new Transit Infrastructure, in Rail Transit Rights Of Way, serving transit District Developments with the capacity to attach to infill developments near transit lines.
