Maintenance is easy, simple and costs very little.<br />

<strong>CITY</strong> <strong>SANITATION</strong> <strong>PLAN</strong> BAREILLY<br />

Needs only 1.5 to 2 litres <strong>of</strong> water for flushing, while conventional flush toilet needs 12 to 14<br />

litres <strong>of</strong> water.<br />

Needs less space than a septic tank toilet system.<br />

Does not need scavengers for cleaning the pits or disposal <strong>of</strong> sludge. This can be done by the<br />

householder.<br />

Makes available rich fertilizer and soil conditioner.<br />

Can be easily connected to sewers when introduced in the area.<br />

A low volume flushing cistern could be attached to avoid pour flushing.<br />

Technology Option for Off-site sanitation systems<br />

Sewerage<br />

Application Level- City Wide<br />

Costly sewerage-based systems are unlikely to be cost effective solutions in most urban areas.<br />

Instead, decentralized excreta management systems are required. While many technological<br />

solutions exist, awareness and knowledge <strong>of</strong> them is limited to a small group <strong>of</strong> experts and needs to<br />

be broadened. Similarly, the technical knowledge <strong>of</strong> decision-makers needs to be increased. In some<br />

situations, such as for slums above water, appropriate technological solutions are yet to be found<br />

and more innovation is needed. Also, comparisons <strong>of</strong> primary and secondary costs and further<br />

investigation <strong>of</strong> what does and does not work, in the case <strong>of</strong> community-developed and managed<br />

facilities would be helpful.<br />

Maintenance: Sewers and manhole chambers will occasionally require structural repair or<br />

replacement, and broken and missing manhole covers should be replaced immediately. In gravity<br />

sewers, wastewater and solids are flushed along the sewer line to a treatment plant. If sewers are<br />

laid to self-cleansing velocities, they should require little routine maintenance. However, silting can<br />

be a problem where falls are limited and/or storm run-<strong>of</strong>f carrying silt enters sewers. In such<br />

situations, periodic rodding, flushing or jetting will be required to remove blockages. Where<br />

pumping is required, considerably more attention will be required to operate and maintain pumps<br />

and other associated electro-mechanical equipment.<br />
