KEY ACTIVITIES AND TECHNICAL ASPECTS PRE-PLANNING PHASE (2-3 MONTHS)
Selection of SO by DWSC based on pre-agreed criteria
Formation of GPWSC if not already there, ensuring representation by women and
as per composition specified in relevant PRI act
Tripartite Agreement between DWSC, State Technical Department and GPWSC for
collaborating for the project for design, planning and implementation
3
KEY ACTIVITIES AND TECHNICAL ASPECTS PRE-PLANNING PHASE (2-3 MONTHS)

Quality, Land availability etc. including other desirable and essential criteria)
Assessment of Source Availability in terms of Quantity/Yield (Secondary data)
Hydro-Geology (Decide the Source), Water demand/usage pattern, habits/practices,
topography, assessment of techno-physical features (including existing impediments
etc.)
Assessment of Affordability (capacity) and Willingness to Pay4
KEY ACTIVITIES AND TECHNICAL ASPECTSPRE-PLANNING PHASE (2-3 MONTHS)
Disclosure of Design principles (Technical) in the villages/ habitations likely to
be benefitted
Assessment of requirements, Identification of technology options, preparation of
feasibility report [assessment of rough costs (capital and O & M cost as well)] on the
basis of thumb rules.
Possible components of the schemes on the basis of above
5
KEY ACTIVITIES AND TECHNICAL ASPECTSPRE-PLANNING PHASE (2-3 MONTHS)

Security Plans for the Block/ District (Guidelines of MoDWS)
Collection of Primary data and Detailed Survey (TSS, correlation to GPS data) etc.
In case of small Schemes consideration of relaxation in Total Station Survey
7
Mobilization of communities, IEC on safe water, hygiene, sanitation and environmental
sanitation and Trainings on community development for GP/GPWSC members.
KEY ACTIVITIES AND TECHNICAL ASPECTS PLANNING PHASE (3-4 MONTHS)
Preparation of SHS/SGS plans by GPWSC (with support from SO/Engineers)-
preliminary designs and line estimates (and specifically including coverage for all section
of population including the SC/ ST/ vulnerable/ marginalised )
8
Gram Sabha Resolution approving the scheme technology and estimates (for SHS/
SGS) and give go ahead for Water Schemes
Disclosure of water security plan details within the habitations and at GP level
Preparation of detailed technical designs of all components and detailed cost
estimates with technical specifications (lump sum provisions be avoided) for Detailed
Project Report. Realistic assessment of O & M costs be done
Submission of brief proposals by GP to DWSC/SPMU for technical and
administrative approval as per delegation of powers
9
KEY ACTIVITIES AND TECHNICAL ASPECTS PLANNING PHASE (3-4 MONTHS)
Submission for Technical Sanction
Receipt of Technical Sanction of SHS/SGS
Bid document: Scope of work with technical specifications and detailed BoQ with
complete technical specification and reference relevant BIS /NBC
- Defect Liability Period – preferably 12 months.
- Liquidated damages clause for delay, performance, environmental and social
safeguard. 10
KEY ACTIVITIES AND TECHNICAL ASPECTS PLANNING PHASE (3-4 MONTHS)
Disclosure of finally approved/sanctioned scheme(s)
Disclosure of community contribution
11
KEY ACTIVITIES AND TECHNICAL ASPECTS PLANNING PHASE (3-4 MONTHS)
Collection of initial (upfront) contribution (ownership feeling)
Reference to HGM maps/ Hydro-geologist report regarding under ground source
Storage capacity should be sum of Maximum deficit and maximum surplus (mass curve)
Detailed maps and detailed drawings with Auto CAD be prepared
Technical Specification with reference to relevant B I S e. g. Concrete grade, pumps,
fittings, etc. 12
Few points to be kept in mind in preparation of DPRs / technical designs
KEY ACTIVITIES AND TECHNICAL ASPECTS PLANNING PHASE (3-4 MONTHS)
Disclosure of all technical and financial details of selected contractor and contract.
Bid Invitation (Technical and Financial) and selection of construction contractor(s) by
GP/GPWSC, as per procurement process (with SO and Technical Department assistance).
Quality controls of materials and construction supervision by GPWSC/ SO
Engineer (Work Finishing and desired workmanship).
- Sample testing in test house (Labs.)
Execution of work with environmental and social safeguards.
13
KEY ACTIVITIES AND TECHNICAL ASPECTS IMPLEMENTATION PHASE
Commissioning of scheme and trial runs
a) Equitable distribution as per design (Quantity, Duration & Pressure).
b) Ensuring disinfection and measurement of residual Chlorine (by choloroscope).
Independent quality check and monitoring by the Third Party (Independent
Construction Quality Surveillance Consultant).
14
Source Water Quality test, Yield test of source.
Recording of measurements, check measurements and payment authorization.
KEY ACTIVITIES AND TECHNICAL ASPECTS IMPLEMENTATION PHASE
Technical and Social Audit and their disclosures.
After completion of the work, preparation of implementation phase completion
report (IPCR) and its disclosures
15
As built/completion drawings of all component. Hidden works/under ground works
e.g. T W (Strata chart during drilling and pipe assembly drawing during lowering of
assembly) ,
KEY ACTIVITIES AND TECHNICAL ASPECTS IMPLEMENTATION PHASE
16
GPWSC take over works from the Contractor.
Continuous IEC activities with monitoring at household and community level.
Compilation & recording of all maps and completion drawings. Due care should be given
for completion drawing of Distribution System (pipe line, fittings, valves, depth etc.).
KEY ACTIVITIES AND TECHNICAL ASPECTS POST IMPLEMENTATION PHASE (O & M)
Preparation of O & M budget, decide on subsidy and tariffs.
17
Disclosure of charges fixed, methodology, charges collected; defaults, etc. at
Habitation/ GP level.
Collection of charges, as applicable by GPWSC.
KEY ACTIVITIES AND TECHNICAL ASPECTS POST IMPLEMENTATION PHASE (O & M)
Water quality Monitoring and surveillance
Carrying out of O&M by GPWSC with assistance from SOs (preferably for
