WWAT WorldWater Develops Project

WWAT WorldWater Develops Project with San Diego County’s Valley Center Municipal Water
District for Solar Powered Pumping System Up to 1.2 Megawatts

PENNINGTON, N.J., Aug 29, 2007 (BUSINESS WIRE)—WorldWater & Solar Technologies
Corp. (OTC BB: WWAT.OB) (formerly WorldWater & Power Corp.), developer and
marketer of proprietary high-power solar systems, announced today it will build a
photovoltaic system up to 1.2 Megawatts to provide electricity and water pumping
power for the Valley Center Municipal Water District (VCMWD) of Valley Center,
California. The system will be owned by Solar Power Partners of Mill Valley,
California, which will operate it for VCMWD under a 20-year Power Purchase
Agreement (PPA). The actual size of the system will be determined by the results
of environmental and site engineering work.

The system will use WorldWater’s proprietary AquaMax(TM) drives to provide
pumping power for drinking water and irrigation. VCMWD is the second largest
water provider in San Diego County behind the City of San Diego.

Gary Arant, General Manager of VCMWD, commented, “Our Board’s vote for this
project was enthusiastic and unanimous. Throughout the process, all involved
recognized the importance of securing clean, reliable, cost effective electric
energy to meet our commitment to our customers and community. With this in mind,
WorldWater, VCMWD’s staff and Solar Partners worked very hard to bring this
project to this point in the process. We are very excited and anxious to keep the
project moving forward and bring it on-line as soon as possible.”

In 2006, WorldWater worked with VCMWD’s Board of Directors on a project
feasibility study and later procured rebates on their behalf from the California
Public Utility Commission through the California Solar Initiative Program.
WorldWater will engineer, supply and construct the system, and will maintain it
for Solar Power Partners. The planned site is near VCMWD’s Betsworth pumping
station in Valley Center. Pending environmental study approvals and final
engineering, construction will start this year with completion scheduled for May
2008.

Quentin T. Kelly, Chairman and CEO of WorldWater, said, “We were selected largely
because of our patented AquaMax(TM) technology which has proven itself highly
effective in water utility operation. It’s the only system that seamlessly
switches back and forth from solar power to the grid or uses solar power alone
for the multifaceted and critical pumping needs of a water district when the grid
goes down.”

Craig Hunt, Co-Founder and CEO of Solar Power Partners, said, “SPP is greatly
pleased to have the Valley Center Municipal Water District as our PPA customer,
and to be working closely with WorldWater to develop this exciting project.”

Aquamax(TM) is the unique solar technology capable of powering electric pumps up
to 1,000 horsepower and operates automatically in combination with grid, battery
and diesel power. The system operates unattended and protects customers from
paying peak grid rates during sunny periods. WorldWater is designated as a
preferred solar supplier by the Association of California Water Agencies (ACWA).

Solar Power Partners, Inc. (SPP(TM)) is a developer, owner, and manager of
mid-size commercial solar energy facilities, built and operated to provide
solar-generated electric power for commercial, educational, public sector,
industrial and agricultural customers. SPP(TM) provides an innovative turnkey
service that bundles development, financing and on-going operations tailored to
meet customers’ specific needs, though the use of Power Purchase Agreement
financing.

California’s State Legislature authorized the Valley Central Municipal Water
District in 1911. The District serves residential, commercial and agricultural
customers in northern San Diego County and covers over a 100 square mile with
nearly 300 miles of water lines.
