Annexure 2 2.1 Scope of Work- Improvement to Storm Water Drains – Specific Tasks Specific tasks of the design and supervision consultancy on works related to Storm Water Drainage improvement apart from the general tasks described earlier are:

a) Using available maps, topographic sheets and by reconnaissance and detailed survey of the catchment and sub-catchment areas, determine storm water flow and show on a plan in the form of modules each module covering the catchment area.

b) Analyze rainfall data of the previous years (no. of years would be in accordance with the standard practice followed in the country) and estimate storm run-off per unit area for various storm frequencies;

c) Prepare an outline drainage plan for the area and identify missing links and prioritized program of improvement works.

d) For priority drainage area, carryout detailed topographic survey and leveling to prepare longitudinal sections of the system and cross sections of important rivers, major channels and drains covering a width of 15 m on either bank generally at intervals of 10 m along with L-sections and detailing all the temporary and permanent structures met within that width. All the structures and encroachments will also be marked with enough details.

e) Indicate the details of other underground services, mainly sewers and water mains (electrical cables) which are in the vicinity of the storm water drainage system and show their distance from storm water drains with a view to know about the possibility of providing by-pass storm water drain and for deciding their location.

f) Indicate the inundation area clearly, showing probable depth of water accumulation in case of intensity of rainfall as agreed with the SPCU.

g) Locate all ponds and flood water holding ponds/zones in part portions of open gardens or playgrounds – showing therein probable size duly dimensioned should be shown on plan along with various arrangements / devices to dispose off the accumulated water to nearest outfall or conserve the water so as to reduce the shortage of water supply and to be shown in a tabular proforma.

h) Carry out analysis of existing situation of storm water drains to identify deficiencies and develop alternative strategies and options for expansion / augmentation of the existing system to address system deficiencies.

i) Prepare detailed cost estimates for priority drainage area. Estimate necessary road restoration charges wherever needed.

j) Prepare a traffic diversion plan as necessary and incorporate in bidding documents. 2.2 Scope of work- Water Supply – Specific Tasks

a) Based on feasibility, the Consultant is required to carry out a detailed engineering design including environmental and social studies and prepare, Detailed Project Reports and bidding documents for all the identified water supply sub-projects .

b) The overall design would cater for a period of over 30 years/ horizon as defined as

per national planning norms and a population as determined by the consultant based on appropriate projection techniques. The designs shall conform to relevant/ latest applicable National Standards, NWSDB guidelines and CEA requirements. Wherever such standards are not available, appropriate standards shall be followed in discussion with SPCU/PMU.

c) Based on the pre-feasibility reports, ,the work involved and the study/output shall

include, but not necessarily limited to the following as necessary:

(i) Designs for development/ rehabilitation of works at source and transmission and distribution for selected Local Authority(s);

(ii) Designs for development/ rehabilitation of constructing treatment plants (as necessary;

(iii) Designs for development/ rehabilitation of Internal distribution lines with adequate regulations to ensure equitable water supply;

(iv) O&M mechanism including a plan and staffing requirements and

(v) A tariff system and a mechanism to update tariff periodically

(vi) Suggest proper zoning and block regulations if any, in order to give equitable water supply with optimal utilization of existing infrastructure facilities.

(vii) Identify potential options for the long-term system improvements with recommendations for addressing environmental, institutional and regulatory issues if any.

(viii) Estimate the investments required including O & M for various identified options with financial analysis taking into consideration the water tariff to be levied for capital and operation and maintenance requirements

(ix) Support LA in preparing actions required for staffing of the water unit and in establishing tariff mechanism

(x) Based on cost-benefit analysis and cost projections, prioritize the investment proposals based on economy and efficiency. t.

d) Soil Investigation: Soil tests as per relevant National/ NWSDB Standards have to be done by consultants to arrive at design parameters for the formation and safe bearing capacity.
