Sewage System Discharge from Cities into Rivers and Ocean .
Processing facilities will need to be set up underground, as first preference.
Private enterprise would be invited to participate either in public-private partnership models or solo private contracted efforts to upgrade the sewage collection pipe-line system by laying parallel new pipes for such collections, replacing the old when built.
This work would be carried out by using boring machines and new technologies including pre-fab modular construction models to build deep underground cavities that would take the city’s pipe lines including sewage, to the processing plants en-route to the river or purpose built artificial lakes discharge.
The idea would be to set up processing units in a manner designed to produce by-products that are saleable such as fertilizer, gases for fuel, recoverable chemicals etc.
Given the woeful infrastructure that is antiquated and groaning under the weight of increased populations in all cities and towns of the country, the government would undertake, in cooperation with State governments the upgrading of all civic infrastructure, without exception.
This would in most cases mean the building of new parallel drainage systems to be built to new designs that reflect current realities.
For instance, a dual pipe system would be considered where in one pipe would be for kitchen and bathroom waste water that would be piped to water treatment or processing plants.
The second pipe could be laid for collection and piping of household waste of human excreta from toilets such that every household would need to connect to both pipes as defined.
The human waste collection would then be piped to waste processing plants that would result in by-products including gases and fertilizers for sale and use in society leading to clean-green technologies and systems.
The kitchen, and bath pipe system would be channeled to water treatment plants that remove the chemicals and bacteria and only then discharge into the river or water-way systems.
Artificial lakes, with parkland around them, could be built throughout city precincts and processed water could be piped to keep these water-bodes charged thus improving the quality of life for the citizens of the cities.
These systems would be built in public-private partnerships with the private sector largely providing the management and running of the systems and downstream enterprises.
Sewage treatment would be open to the private sector who would set up collection and treatment plants.
Funding of such plants would also be opened to private sector with the government cross subsidizing where necessary to ensure commercial viability.
Processing Plant projects would be evaluated on the basis of saleable by products by value such as manure, methane gas and other derivatives that can be monetized.
All possible models would be considered including that these plants could be established with “root-costing-plus margin” forming the basis of State-Private sector negotiation.
The entrepreneur would be permitted recovery of capital with interest equivalent of five times capital investment free of tax, and nil or very low government levy’s shall be imposed as required for ensuring commercial viability.
Once the plant investment is paid for, the state would collect up to 25% of gross sale or profit value and on the profit of the unit, where available.
Thereafter a pre-stipulated tax on net disposable profit would be collected for the public coffers.
Private sector would be encouraged to lay its own pipe system and collection points for a given mass of financially viable product collection by volume area.
Such pipes would be all underground and with capacities that take 75 years growth, with flexibility to double the system in the design phase itself to include the underground cavity and pipe rail systems.
