2. The state has been able to provide water to 79% of the urban and
59% of the rural population and efforts are being made to cover the
rest of the population.
Accordingly a very ambitious project known as Kerala Water
Supply Project (KWSP) was derived with support of International
Corporation - Japan International Corporation Agency (JICA). Five
Schemes under KWSP:
•Trivandrum
•Meenard
•Cherthala (Kollam)
•Kozhikode (Calicut)
•Pattuvam (in Kannur District)
KERALA WATER SUPPLY PROJECT
(KWSP) & PATTUVAM SCHEME

3. KERALA WATER SUPPLY
PROJECT (KWSP)
• The Government of India is the borrower and the Kerala Water
Authority is the executing Agency. This Project aims at rehabilitating
and augmenting the water supply systems of two urban regions
namely Kozhikode and Thiruvananthapuram and to construct new
water supply systems for three rural regions namely, Pattuvam of
Kannur district, Cherthala of Alappuzha district and Meenad of
Kollam district. Pattuvam Scheme is the north most beneficial area
from this massive project.
• The international consultants M/s TEC consortium (with Black &
Veatch, GKW, STC, CED) led by M/s Tokyo Engineering
Consultants Company Ltd (TEC). Japan has been selected by the
KWA to manage the implementation of the project.

KERALA WATER SUPPLY
PROJECT (KWSP) & PATTUVAM
SCHEME
Kerala is a state located in
southwestern India. Neighboring
states include Karnataka to the
north and Tamil Nadu to the south
and east, and the Arabian Sea is to
the west. Major cities include the
state capital of Trivandrum
(Thiruvanaputhram), Kollam,
Cochin, Calicut (Kozhikode) and
Kannur (Cannore).

6. The Pattuvam Scheme is in Kannur District is the northern most
area benefits with the KWSP. The objective of the scheme is to
supply safe and potable water to 530,000 consumers in 10 villages,
7 semi-urban areas and 1 municipality in the Kannur District by
constructing new facilities. Facilities include technical components
for water abstraction, raw water transmission, water treatment,
treated water transmission, storage reservoirs and distribution
networks.
The project area covers 350 km2 and the water demand of the area
is estimated as 93 MLD. The source is at Pazhassi Barrage at
Valapattanam River at Kuiloor and the method of extraction is by
intake well. The raw water is boosted through steel pipe of 1100
mm diameter for a length of 11 km, to the Treatment Plant. The
capacity of the Treatment Plant located at Peruvalathuparamba is
93 millions liters per day.

10. Project Highlights
• About 1,000,000 cubic meters of earthwork; 720 kilometres of
pipelines; 25,000 cubic meters of concrete and 2000 tonnes of steel.
Total project value is USD80 Million.
• The project is unique in its nature and complexities, characterised by
its spread across a large area. In view of the massiveness of the
project and the complexities in the nature of the work components, it is
a challenge and however essential and important for the Senior
Resident Engineer to put in place a comprehensive project
management, supervision, quality assurance and control during the
implementation.
• The Project is being executed following a fast track approach.
